Many people have heard that certain regions are well-suited for these projects, for example the Northeast Corridor is unusually good for HSR because it links four major cities and several medium-size ones on a single line. By implication, there has to be a flip side, i.e. regions that are poorly-suited for HSR and cities that are poorly-suited for new rapid transit. If there weren’t – if every region were like the Northeast Corridor – then the ridership models would just have higher first-order estimates. Several proposals I’ve seen in comments and on my blogroll in the last few days are in areas where the urban geography makes it harder to justify such projects. These and a few others are the examples I will use in this post.
As usual, there’s a caveat that difficult does not equal bad. Some of these ideas are worth pursuing, but have more challenges that their easier counterparts do not, and if those challenges are solved, then they can perform well. One of the biggest success stories of modern rail investment, the TGV, is in an urban geography that’s not particularly conducive to rail: France’s secondary cities surround Paris in all directions (although Lyon and Marseille are collinear with Paris), the stub-end layout of stations in Paris and many other cities forces awkward branching, Lyon needed a business district to be built from scratch around Part-Dieu. France made this work, and it’s possible some of the projects on this list can be made to work in similar vein.
High-Speed Rail in Sweden
Project: greenfield HSR lines connecting Stockholm with Sweden’s major secondary cities, Gothenburg and Malmö.
The problem: Stockholm, Gothenburg, and Malmö do not lie on a straight line. The three cities are quite small by the standards of more populated countries: Stockholm has a bit more than 2 million people, Gothenburg has a bit less than a million, Malmö has 700,000. A line connecting just two of them, or even a Y-shaped line, is unlikely to get enough ridership to justify the construction costs of full HSR. There are no large intermediate cities: the largest, Linköping, has about 100,000 people. As noted above, French urban geography is not great for HSR, either, but at least the LGV Sud-Est could serve both Lyon and Marseille, and France’s greater population ensures that its secondary cities are large enough to generate enough traffic to fill an HSR line.
As a silver lining, Malmö is adjacent to Copenhagen, and the difficult part, bridging the Øresund, has already been done. While international lines tend to underperform, the tight cultural and economic connections between the Scandinavian countries make it likely that international projects within Scandinavia would be exceptions to the rule. Copenhagen would add another 2 million people at the end of the line. However, even that is unlikely to generate enough ridership to pay for 500-odd kilometers of greenfield HSR (plus a connection to Gothenburg).
Because of its poor urban geography for conventional HSR, Sweden has investigated cheaper solutions, allowing higher speeds on legacy track or on greenfield tracks built to lower standards. As a result, there is research into the possibility of high-speed tilting trains, running faster than the 250 km/h Pendolino. This research is likely to be useful in the UK and US, where the urban geography is better-suited for HSR but fully greenfield construction is obstructed by suburban development near the rights-of-way and by high construction costs, but the original context was faster speeds within Sweden.
High-Speed Rail in the Pacific Northwest
Project: greenfield HSR connecting Portland, Seattle, and Vancouver. This is not officially proposed anywhere that I know; current plans focus on incremental improvements to the Amtrak Cascades. However, every American HSR fantasy map I’ve seen (including the ones I’ve drawn) includes this link, since at least superficially based on city populations it would succeed.
The problem: getting out of the major cities involves a slog on curvy legacy track in areas where it’s hard to straighten the right-of-way. Heading north of Seattle, the route goes along the water, in terrain that is too hilly for an easy inland cutoff all the way to Everett, 50 km north. Getting out of Vancouver is also hard, because of suburban development in Surrey, and becomes even harder if one wants the Vancouver station to be Waterfront rather than Amtrak’s current stop, the less centrally located Pacific Central. The Northeast Corridor is said to have slowdowns near the major stations, leading to proposals to bypass them with new tunnels, but at no point are there 50 nearly-continuous km of low curve radii; the New Haven Line does not look as curvy, while the Shore Line farther east is easy to bypass on I-95.
The Seattle-Portland segment is much easier: the route heading south of Seattle is not constrained, and north of Portland it is possible to run alongside I-5. However, the most important intermediate cities, Tacoma and Olympia, can only be served with exurban stations, since getting into their centers would require the mainline to detour on curvy alignments.
Through-Run Commuter Rail in Chicago
Project: there are many proposals by transit activists to construct new infrastructure to enable through-running on Metra, analogous to Crossrail, SEPTA Regional Rail, the Paris RER, and multiple S-Bahns. Details differ, but other than the lines through Union Station, through-running generally means connecting Metra Electric to some of the lines feeding into Union Station from the north or the Union Pacific lines; UP-North is especially notable for serving dense neighborhoods and not having any freight traffic.
The problem: the layout of the lines entering the Chicago central business district makes it hard to build a coherent network. What I mean by coherent is that commuter lines can make multiple CBD stops to serve different CBDs, or different parts of the same CBD: in New York, a Penn Station-Grand Central connection would let trains serve both the West Side and the East Side. Look at the map proposed by Sandy Johnston, in the second link above: there is no station on the Near North Side, there is no connection from the West Loop stations to the Loop, and effectively lines are still going to be split between lines bound for the West Loop and lines bound for the Loop in the through-run system.
None of this is the fault of any of the people drawing these maps. To serve both the West Loop and the Loop, a line would have to go east-west in the vicinity of Union Station, where there is no legacy line pointing in the right direction. The options boil down to a long greenfield east-west subway, and an awkward transition to the preexisting east-west lines, BNSF (which is too far south) and UP-West (which is too far north), which to add another complication carry heavy freight traffic.
A system prioritizing north-south connections runs into different dilemmas, concerning the tradeoff between service to the Near North Side and easier connections to the rest of the North Side Metra lines. A north-south line connecting UP-North to Metra Electric through the Near North Side would be beautiful, and miss all other Metra lines and most L lines. Sandy’s proposal has Metra Electric swerving west to meet UP-North just north of its terminus at Ogilvie Transportation Center, meeting all L lines and potentially the North Side Metra lines but missing the job centers in the West Loop and Near North Side.
Rail to LaGuardia
Project: construct some rail extension to LaGuardia Airport. Which rail extension varies based on the proposal. The most mainstream proposal, in the sense that it was supported by Giuliani until it was torpedoed by neighborhood opposition, would have extended the Astoria Line east to airport grounds. More recent proposals from various activists have included not just the Astoria Line extension, but also a Northeast Corridor spur, an AirTrain from the Astoria Line, an AirTrain from Jamaica with JFK connections, a subway shuttle under Junction, and a subway running from the airport to 125th Street along the route of the M60 bus.
The problem: all of the above ideas face the same pair of problems. At the airport end, the airport competes with other urban destinations, rather than complementing them by lying on the same straight line with them. An extension from the west, such as the Astoria Line extension, needs to choose between serving the airport and serving the Astoria Boulevard corridor, which has high residential density and no nearby subway service; Astoria Boulevard itself is so wide that as with Queens Boulevard, an elevated line in its middle would be an improvement. Farther east, there is nothing that a LaGuardia extension could be continued to, because of Flushing Bay. An extension across the bay going to Flushing or College Point could be useful, but an extension of the 7 to College Point would be even more useful and avoid underwater tunneling. The bay, and more generally the Long Island Sound, dooms any proposal for a loop returning to the mainline, in the manner of Zurich Airport, while a spur would again compete for capacity with more important lines. Compare this with LAX, which, going along the Harbor Subdivision, is collinear with Inglewood, the Slauson corridor, and Union Station, and would have an easy connection to El Segundo.
At the other end, the question with every airport extension is, what does it connect the airport to? The answer for LaGuardia has to be the Upper East Side, where as I remember most riders originate; but there is no good way of connecting to the Upper East Side, which has no east-west subway line, and shouldn’t, as there are perhaps a hundred kilometers of higher-priority tunnels in the region. A connection to 125th Street is ruled out by the fact that Second Avenue Subway has an even better connection to 125th. The Astoria Line serves the Midtown hotel cluster well, and has a connection to the Lexington trains to the Upper East Side, but I doubt that it can beat a taxi across the bridge in non-rush-hour traffic.
Providence East Side Tunnel
Project: restore rail service through the East Side Rail Tunnel, with a new connection to Downcity at the western end and connections to new or restored rail lines in and beyond East Providence. In Jef Nickerson’s version, the trains are light rail and drop to the surface at the Downcity end. In mine, they continue elevated through Downcity, with a new station replacing Providence Station for both commuter and intercity rail. All versions include a stop at Thayer Street for Brown University service, should one be constructable at reasonable cost.
The problem: there’s no real need for local or regional service from the east along the tunnel (intercity service could be sped up by about half a minute to a minute by avoiding curves in Pawtucket). Light rail service would run into the problem of incredibly spread-out suburbanization east of Providence. Commuter rail would run into separate problems: the legacy lines go along the water in East Providence and don’t serve the town itself well; beyond East Providence, the line going north serves the same suburbs as the existing Providence Line minus Pawtucket, while the line going south would need extensive and costly restoration work to get to Fall River, and only passes through small and low-density intermediate points.
Cutting off Providence Station to move the city’s main station to the south is useful, but the only rail from Providence to Pawtucket and Woonsocket goes due north of Downcity and would be left out of this system. Shoehorning it to the same station that leads to the East Side Tunnel would produce every adverse impact of viaducts on cities: heavy visual impact coming from elevated-over-elevated grade separation, squeal coming from low curve radii, takings of condo buildings near the existing Providence Station.
So, you have your urban rail line. It’s mostly above ground, so constructing new express overtakes is feasible. It has decent frequency, and carries trains to destinations at a variety of distances from city center. But it’s not an overcrowded subway line that brushes up against line capacity, requiring all trains to run at the same speed. Do you run express trains?
I’m going to focus on regional rail in this post, since with two Tokyo-area exceptions, proper subways are incapable of running express trains without dedicated express tracks due to their high frequency. On a line with a train every 10 minutes it’s feasible to mix trains of different speeds with timed overtakes; on a line with a train every 2 minutes, it’s not. I’m going to use the LIRR and Caltrain as examples, and then apply the derived general principles to other cases in the US, including future regional rail schemes.
The basic tradeoff of express service is that it provides faster service to the express stations at the cost of frequency at the local ones. This can be done in two ways: expresses that stop once every few stations, and local-then-express patterns. Jarrett Walker calls this limited versus express, based on bus service patterns; with trains, both types are called express. The subway in New York, the Chuo Rapid Line, Seoul Subway Line 1, and Caltrain baby bullets are examples of the first kind; the Caltrain limited-stop trains and the peak-hour trains on some LIRR lines are examples of the second kind.
Express trains of either kind but especially the first reduce line capacity, even with very long overtake segments. If train X overtakes train L, then there needs to be an available slot ahead of train L, and after the overtake there’s a slot opening up behind L. The Chuo Rapid Line runs a mixture of local (“rapid”) and express (“special rapid”) trains for most of the day, but at rush hour, there are only local trains, peaking at 28 trains per hour; on the shoulders of rush hour, there are some express trains, with total traffic of about 20 tph. The LIRR runs 23 tph on the Main Line at the peak, so this is an issue, which the LIRR unsatisfyingly resolves by running trains one-way at rush hour. It’s less an issue on Caltrain given constructable overtake locations, but right now the overtake locations are inconvenient and the trains are pulled by diesel locomotives, increasing the stop penalty and reducing the capacity of a mixed local-express line.
The second kind of express service is bad industry practice and should not be used. It avoids the capacity problems of the first kind at low traffic levels, but at high traffic levels the speed difference is still too large. It is used when the trains are a special CBD shuttle and makes it impossible to serve passengers who are cheap to serve, i.e. those getting off short of city center. Caltrain’s limited-stop trains do this because of capacity problems during rush hour, when they need to get out of the baby bullets’ way. The LIRR does this because of a cultural belief that trains exist only to shuttle people from Long Island to Manhattan and back; due to the same belief, it runs trains one-way at rush hour rather than giving up on rush hour express runs as JR East does.
The first kind of express service may or may not be warranted. It depends on the following questions:
1. What is the line’s expected traffic level? Low traffic, up to about 4 tph for a regional line, favors an all-local configuration to prevent cutting local stations’ frequency unacceptably. Very high traffic favors all-local configuration for capacity reasons, or else investment into long overtakes or even full four-tracking. Intermediate traffic, in the 6-12 tph range, is the best zone for express trains.
2. Have local trains already been sped up by use of good industry practices? Level boarding, high-acceleration EMUs, better track maintenance allowing higher speeds between stations, good timetable adherence allowing less schedule padding, and infrastructure preventing delays on one train from cascading to others allowing even less padding can all significantly reduce the speed difference between local and express trains. In some extreme cases, a local train can end up not much slower than an express train hauled by a diesel locomotive.
3. How long is the line, and how many stations does it have? Longer lines and shorter interstations both favor express trains, all else being equal. Intercity rail, which also has higher stop penalties because of the higher line speed, deserves more than one stopping pattern even at low frequencies.
4. How big is the difference between minor and major stations? It is crucial not to confuse current ridership with ridership potential, since lines with express service often pick winners and losers, after which the better-served express stations steal riders who live closer to bypassed minor stops. This is common on Caltrain, where some but not all express stops are major job centers.
5. Can intercity trains plausible substitute for express service?
It is question 4 that makes the difference in many cases. On the LIRR, the Main Line has a clear distinction between major stops (Mineola, Hicksville) and minor ones (all the rest). The Montauk Line does not. Note the ridership levels of the stations, going eastward from Jamaica to the end of electrification:
Queens Village: 791
Floral Park: 1495.5
New Hyde Park: 1725.5
Merillon Avenue: 766.5
Carle Place: 386
Cold Spring Harbor: 2083
Deer Park: 2708.5
Central Islip: 1787
St. Albans: 93.5
Rockville Centre: 3425
Massapequa Park: 1672.5
There are three ends of electrification: Babylon, Huntington, and Ronkonkoma. All have markedly more ridership than nearby stations, especially Ronkonkoma, though in all cases it’s an artifact of their being the ends of electrification, with many people driving in from farther east. Ronkonkoma has nothing nearby that justifies its ridership level, the highest of any suburban LIRR station; it’s a park-and-ride that has a lot of ridership because it’s the end of electrification and has express service.
In contrast, in Mineola and Hicksville, there really is a concentration of activity justifying their status. Both have trivial transit usage as job centers, but there’s enough of a core, especially around Mineola, to justify higher service, and Hicksville is also the junction of the Main Line with the Port Jefferson Branch: see the census bureau’s OnTheMap tool.
But there are no special stations on the Montauk Line. Excluding St. Albans, which is in New York itself and has to compete with cheaper and more frequent if slower bus-to-subway options, the ratio between the busiest and least busy stations is 2.4:1. A similarly flat situation occurs east of Hicksville, excluding the two end-of-electrification stations.
What this means is that the LIRR should only run local trains on the Babylon Branch and east of Hicksville, while maintaining express service on the Main Line west of Hicksville when there’s enough capacity for it. A similar analysis of other lines in the New York area should give the following answers:
Hempstead, West Hempstead, Long Beach, and Far Rockaway Branches: all local due to short length.
Port Washington Branch: probably all local due to short length, but if additional local stations are added in Queens, then some express trains to Great Neck may be warranted.
New Haven Line: very long, sharp distinction between major and minor stops all the way but especially west of Stamford, high frequency, four tracks give enough capacity for everything. The current configuration of nonstop trains to Stamford continuing as local to New Haven and local trains turning at Stamford is fine, except that the express trains should also stop at New Rochelle (a junction with the Hell Gate Line, which deserves service, but also a major stop in and of itself, with the third highest weekday ridership of Metro-North’s suburban stations) and maybe also Greenwich; HSR overtake considerations may require stopping also at Rye and Port Chester.
Harlem Line: generally favors local trains, except that White Plains is a major job center and thus a far more important stop than all others, independently of its better service. There are four tracks south of Wakefield, favoring express trains, but conversely charging subway fares and allowing free transfers to the subway would lead to a ridership spike as people switch from the overcrowded 4 and 5 trains. There’s a big dropoff in ridership north of North White Plains, so the current configuration of locals that turn at North White Plains and expresses that go nonstop south of White Plains is fine, as long as off-peak frequency is raised.
Hudson Line: favors express trains because of length and four-tracking. Although on paper there are more and less important stations, this is an artifact of service patterns. The secondary stations in Yonkers serve higher density than the busier stations in the proper suburbs, and the dense parts near Tarrytown are actually in Sleepy Hollow, about equidistant from the Tarrytown and Philipse Manor stations: see the New York Times’ population density map.
Erie Lines and West Shore Line: probably all local since the population density thins too uniformly going north, with Paterson as the major exception. There are somewhat denser anchors at the outer ends of some lines – Spring Valley and Nyack – but Harlem Line-style nonstops run against a capacity problem, coming from the fact that this part of the network is necessarily highly branched.
Rest of New Jersey Transit: the main lines (Northeast Corridor, Morristown) are very long and have some distinguished suburban job and population centers (Metropark, New Brunswick Morristown) deserving express service, but the branches (North Jersey Coast, Montclair, Gladstone) do not. However, the fare structure and off-peak frequency lead to much less ridership on the inner-urban segments in Newark, Orange, etc., than would be expected based on population density. In addition, the difference between major and minor stops is fairly small on all lines when taking electrification into account, sometimes as small as on the Babylon Branch: see ridership data per line and per station.
Although my initial decision in my regional rail plan to pair the Erie lines with the Atlantic and Babylon Branches of the LIRR was aesthetic, creating a northwest-to-southeast line, in reality the systems are fairly similar in their characteristics. More or less the same can be said about the Staten Island-Harlem system. There are no direct connections to intercity rail except at Jamaica and in the Metro-North tunnel to Grand Central, the lines pass through urban or dense-suburban areas, the interstations are fairly short, and there’s relatively little distinction between major and minor stops. (White Plains is the major exception, and Paterson is a secondary one.) This makes the Lower Manhattan-based system much more RER-like than the Penn Station-based one, which is longer-distance and practically intercity at places.
Finally, the same set of questions in the other three major Northeastern cities generally lead to the conclusion that no express trains are needed.
In Boston, there’s too little difference between major and minor stops on each line (see PDF-page 70) – somewhat more than on the Babylon Branch, but much less than on the LIRR Main Line. The most prominent major station is Salem, but the low-ridership stations farther in on the Rockport/Newburyport Line are in working-class suburbs; the ridership there is depressed because of fare and schedule issues coming from competition with buses, and good regional rail would get much more additional ridership from Lynn and Chelsea than from Salem and the suburbs farther out.
In Washington, current traffic demand is so low that express service would seriously eat away at the frequency offered to local stations. MARC and VRE ridership is so low that any analysis of travel demand has to start from geographic and demographic information rather than from preexisting ridership; the only major outlying destination on any of the lines is Baltimore, which can be connected to Washington by intercity rail, and which conversely has much less Washington-bound commuter traffic than the Washington suburbs. The closest thing to justifiable express service is that when the commuter lines closely parallel Metro, they should have wider stop spacing.
In Philadelphia, on most lines, express service eats away at frequency too much. The one exception is the PRR Main Line, with the SEPTA Main Line a possibility. Many lines have sharp differences between local and express stations: for example, Cornwells Heights on the Trenton Line is much busier than the rest. But a combination of low frequency and lack of easy overtakes (on the Trenton Line, the inner tracks should be mainly used by intercity trains, with only the occasional regional rail overtake if required) makes this not useful. The PRR Main Line actually has less difference between major and minor stops than many others, but it is longer and has short interstations and higher frequency. The SEPTA Main Line has the frequency to support multiple stopping patterns, though the population density near the minor stations is high and the problem, as in other Northeastern cities, is high fares and lack of integration with urban transit.
If new high-speed rail construction has to largely follow Interstate corridors, then a new line from New Haven to Boston can serve either Providence on I-95 or Hartford on I-91/84/90, but not both. However, there’s still the possibility of building a completely greenfield alignment between Hartford and Providence; the FRA is investigating this as option 13 of NEC Future and Amtrak is proposing this in the latest update of its Vision. Since the terrain is hillier than on the coast, it requires some investigation as to whether it’s possible to connect Hartford and Providence without excessive tunneling. The answer turns out to be yes, but only at the cost of slowdowns both north and south of Hartford that impose real costs relative to following I-95: construction is likely to be more expensive and travel time including a Hartford stop is 9 minutes longer.
I believe the alignments depicted in this map are near-optimal for New Haven-Providence via I-95 and via Hartford. The New Haven-Hartford alignment is similar to that of Penn Design with two major differences: Penn Design diverges to cut off some curves near Hartford, but to guarantee sufficient curve radius it has to slice a significant chunk of downtown New Britain; and Penn Design also straightens the route in New Haven with a tunnel, which is unnecessary as the time savings do not justify the expense. Amtrak prefers getting to Hartford from Danbury, but to get there from New Rochelle requires long suburban tunnels, which my alignment avoids. I have not seen a detailed Hartford-Providence alignment, and I drew a line based on Google Earth elevation with an eye toward avoiding tunneling, which means there may be some further optimization, for example a rigorous cost-benefit analysis of viaducts versus curve avoidance.
The Hartford-Providence greenfield route has no tunnels except in Providence itself, where the line tunnels under Olneyville for about 2 kilometers. In Connecticut the route has many viaducts, but does not need to tunnel through the inland hills. Rather than giving detailed cost estimates, which are possible but not with sufficient reliability or precision, I am going to qualitatively describe construction challenges for each route and then the differences in travel time, which favor not serving Hartford. The final decision should boil down to the question, what cost is it acceptable to impose on New York-Boston travelers to allow for service to Hartford?
The I-95 route is zero-tunnel. The Hartford route has no tunnels in Connecticut, but requires a tunnel of 1.5-2 km in Providence. There exists an old railroad alignment going around the river and connecting Providence to the west without a tunnel, but the right of way was given away and to restore it would require some urban building demolitions as well as configuring a flying junction under Route 6 while also slowing down trains further.
The I-95 route has significant challenges in river crossings, since it is close to the coast. Three difficult crossings are needed, of the Quinnipiac, the Connecticut, and the Thames. The Connecticut only requires a span parallel to I-95. The Quinnipiac requires a new span parallel to US 1 and I-95 and a new approach from Union Station; there is space for this approach, and the curve radius can be kept to at least 500 meters, but it requires work on active track. The Quinnipiac span can be avoided by using the existing route around the bay, which crosses the river at a much narrower point, but this adds several slow kilometers to the route. Recent construction costs for parallel bridges are $125 million for the four-lane US 1 bridge and $554 million for a signature ten-lane I-95 span; I believe the lower cost is more indicative of the infrastructure required for a two-track rail bridge.
The Thames is the hardest, since the route of I-95 and the terrain make it hard to cross anywhere except downtown New London, a constrained urban location. There is just enough space for a station between the decks, and the alignment may impose further constraints on curve radius. There is more space north of both decks, or alternatively Connecticut could build a third I-95 deck and repurpose one of the existing decks for rail.
The Hartford route has one significant water challenge: crossing the Connecticut in downtown Hartford. There is an existing bridge, but it is single-track and would require a completely new span to be used by high-speed rail. It is also used by freight, but only by a short branch line that could be bought out.
The Hartford route also needs to cross the Scituate Reservoir, adding about 3 kilometers of viaduct. However, there is a choice of where exactly to cross it and not much development on its banks, making construction easier than on I-95 or across the Connecticut in Hartford.
Terrain and viaducts
I-95 is substantially flatter than the inland route. Only two short segments require significant overland viaducts and earthworks: the transition in southern Rhode Island from I-95 to the Shore Line, and the curve west of New London cutting off curvier parts of the Interstate. The transition is in total 16 km long but only about the western 10 km of it are difficult (of which about half require viaducts and half can be done cut-and-fill), and west of New London there are 6 difficult km requiring a viaduct north of the Niantic.
In contrast, the inland route needs to be on viaduct for a significant portion of the Hartford-Providence section. Of particular note is the Quinebaug River valley, about 13 kilometers of route of which most requires extensive grading and viaducts, as well as some takings in the built-up areas of the towns of Brooklyn and Killingly. The Willimantic River-Mansfield Hollow Lake-Natchaug River complex adds another 16 kilometers, some hard and some less hard; the Willimantic itself is in a deep valley requiring a tall viaduct of about 3 km, and the total viaduct length required appears to be about 8 km. The following 12 km, on the crest heading to I-84, require some earthworks, but probably no significant viaducts.
Urban construction challenges
I-95 has an existing route into Providence. Some curve modifications from East Greenwich northward are helpful for keeping speeds up, but the grade-separated route already exists. The main challenge is fitting regional trains if Rhode Island desires to run them: the right-of-way has room for four tracks but only if track centers are narrowed so much as to preclude tilting, reducing cant deficiency to about 125 mm. At the New Haven end, the main challenge is crossing the Quinnipiac, but once the tracks are east of the harbor, suburban development intensity drops rapidly, requiring only occasional grade separations with roads crossing I-95. Conversely, if intercity trains are all routed through Hartford then no new construction is required for any Rhode Island regional rail.
The major problem then is New London. The entire complex of crossing the city and the Thames is the biggest difficulty in the route, as outlined above in the water crossing section. In addition to geometric difficulties, there are also noise abatement issues, since the track geometry still allows very high speeds (the curve drawn above just west of New London looks like it can be eased to about 3 km, allowing 310 km/h). This is what favors putting the tracks between the two I-95 bridge decks instead of to the north.
The inland route has far greater difficulties. First, it needs to carve a partially new route into Providence, hence the Olneyville tunnel; however, it also leaves the Providence built-up area much faster, within about 6 kilometers vs. 24 for the Shore Line. In New Haven and Hartford it can for the most part transition between legacy rail routes and expressway corridors, but a substantial portion of the route is in the suburbs of those two cities, which requires more grade separations and makes curve modification harder. There are also noise abatement issues, though Shinkansen trains skip some urban stations at 300 km/h, so those issues are more about cost than about speed limits.
There are several alignment choices north of New Haven. The one I used on the map follows the Providence and Worcester’s Middletown Branch right-of-way and thence I-91, but it is equally feasible to take a more westerly route via the Amtrak line transitioning either to I-91 or Route 15; both options involve grade crossings and extensive suburban construction. In all cases, the trains are almost continuously in built-up area from New Haven until 19 kilometers east of Hartford. Grade separations have the full cost of urban or dense-suburban construction, and moreover, the transition to I-384 east of Hartford requires some additional takings.
Total new construction
This is the primary advantage of I-95, cost-wise: the track already exists from Kingston north and requires only minor facelifts. The New Haven-Kingston construction is just 124 km, whereas between the splits with the legacy Northeast Corridor in New Haven and Providence the Hartford route is 167 km.
With this in mind, nearly the entire I-95/Shore Line segment between East Greenwich and East Haven can be eased to a curve radius of 4 km. New London, where noise abatement prevents running at full speed anyway, can accommodate slightly lower radius, about 3 km on the western approach. At the New Haven end, the transition to the Quinnipiac bridge right next to the station has radius 500 meters, but the speed restriction is minor since it is so close to the station.
Hartford-Providence can also be eased to quite high curve radius. In Rhode Island, once out of the Providence built-up area, the tracks can maintain a 4-km standard, and until the transition to I-384, the worst radius is 3.1 km around Mansfield. However, from I-384 west, things become far worse: the transition to the east has a radius of 1.2 km and seems impossible to increase further, the transition to the west has a radius of at most about 1 km, and the curve west of the Connecticut bridge is 500 m and is slightly farther away from Hartford than the Quinnipiac bridge curve is from New Haven.
It is south of Hartford that things deteriorate. The worst curves on the legacy lines are in Meriden and can be bypassed, but there is a 1.3-km curve in New Britain, on an S with a 2.3-km curve just south in Kensington that makes it unfixable. At the New Haven end there’s a curve on the legacy line, bypassed on I-95 by the Quinnipiac bridge, with radius about 450 m about 2.5 km out of the station.
Overall travel time
The explicit assumptions on trains are aggressive, based as always on the need to keep speeds up in big cities and on the only partially fixable New York-New Haven segment. Trains accelerate like the N700-I (26.74 kW/t, more than any high-speed train that currently exists except the Talgo AVRIL), cant deficiency is 175 mm as on the E5/E6 and on the AVRIL, cant is 200 mm as on the Tokaido Shinkansen, and initial acceleration is 0.89 m/s^2 as on the N700-I. With these performance specs, the minimum curve radius required for a full speed of 360 km/h is 4 kilometers; the Tohoku Shinkansen has such radius and JR East intended to run trains on it at 360 km/h before deciding to reduce speeds to 320 for reasons that are not track geometry.
For simplicity of computation I’m going to ignore grades. Since the I-95 route is flat, with very few grades higher than about 1%, this is justifiable there; it’s a little less justifiable through Hartford because a few segments have 3% grades, but they are also quite limited.
Without any schedule padding, we can set the following speed zones for I-95, measuring from 0 km point in Providence and going southbound:
0-0.6 km: 90 km/h (curve around Providence Station)
0.6-4.5 km: 120 km/h (two 450-m curves)
4.5-7.5 km: 180 km/h (Mashapaug Pond curve is too close to 120 km/h to matter, curve into Cranston is about 1 km)
7.5-17 km: 250 km/h (no curves, trains can achieve 270 in between curves but this would only save 5 seconds)
17-22 km: 220 km/h (curves have radius about 1.4 km and the controlling curve at km-point 17 can be eased a bit)
22-92 km: 360 km/h (full speed to New London)
92-103 km: 310 km/h (speed restriction in New London and the curve north of the Niantic River)
103-162 km: 360 km/h (full speed to East Haven)
162-167 km: 250 km/h (curve around an East Haven hill, though trains can barely accelerate fast enough for it to matter going eastbound)
167-168 km: 100 km/h (New Haven approach)
The time taken to transition between speed zones is the average of acceleration and deceleration time penalty. This gives a technical travel time of 33:40 for nonstop trains. If trains have a top speed of 300 km/h, this raises the technical travel time to 37:28.
Now, let us set speed zones for the Hartford route:
0-0.6 km: 90 km/h (curve around Providence Station)
0.6-4.5 km: 180 km/h (curve north of Hartford)
4.5-6.5 km: 200 km/h (curve into Johnston)
6.5-10 km: 240 km/h (curve west of I-295)
10-57 km: 360 km/h (full speed to the Hampton-Mansfield area)
57-86 km: 310 km/h (Hampton and Mansfield impose a 310 km/h restriction to km-point 67, and trains going eastbound can’t accelerate to 360 before they have to slow down again anyway)
86-88 km: 220 km/h (gentler curve in the transition to I-384)
88-101 km: 200 km/h (transition curve to I-384, further curves on I-384 making speedup between transition curves pointless)
101-103 km: 160 km/h (transition curve)
103-109 km: 200 km/h (minor opportunity to make up time, saves 20 seconds over 160 km/h)
109-110 km: 130 km/h (curve on eastern approach to bridge)
110-112 km: 110 km/h (curve on western approach)
Hartford Station: all trains stop since curves limit time savings from not stopping, as at New Haven and Providence
112-127 km: 250 km/h (New Britain curve, speed increase to 270 km/h in between is possible but saves only about 8 seconds)
127-153.5 km: 270 km/h (Kensington and Berlin curves preclude higher speed)
153.5-155 km: 210 km/h (S-curve precludes easy straightening, and significant speed boost requires significant residential takings)
155-169 km: 250 km/h (this requires straightening the kink around and north of the I-91 underpass, otherwise 210 km/h to km-point 162, 160 km/h to km-point 164, and 200 km/h farther south)
169-172 km: 120 km/h (New Haven approach, legacy line curve)
The travel time is 25:30 for nonstop trains from Providence to Hartford and 16:10 from Hartford to New Haven. With a minute of dwell time at Hartford, this is exactly 9 minutes longer than I-95.
Compatibility with other plans
Although I-95 requires less construction overall than Hartford and the construction difficulties are about comparable, Hartford is more compatible with other intercity rail plans for New England, which reduces the advantage of I-95. Under an I-95 option, it is still useful to serve Hartford (and Springfield), which means the Amtrak Shuttle line needs to be electrified, double-tracked, and partially curve-modified anyway. Under the Hartford option this is not required except to provide regional service to Wallingford and Meriden, so the bypassed parts of the legacy line could be built to lower standards.
That said, 60 km of 160-200 km/h electrified track is still a lot cheaper than 60 km of 250-270 km/h track, which means that this reduces the cost advantage of I-95 but does not eliminate it. Of course 60 km of 250-270 km/h track is cheaper than 60 km of 360 km/h track, but I-95 still involves much less overall greenfield track construction.Hartford is also more compatible with any plans Rhode Island might make for southward commuter rail service. The current plans are too low-ridership to bother accommodating, but future plans might involve higher service levels.
Conversely, I-95 is useful for Shore Line East service, since regional trains could use the Quinnipiac bridge as a shortcut. The tracks cross in East Haven and a track connection could be built; it is likely that there will always be enough capacity for 5 km of track-sharing between intercity and regional trains. I-95 is also useful for the New London connection in case anyone wants to build a New London-Norwich regional train serving Mohegan Sun on the way.
Neither route is particularly expensive by the standards of what both Penn Design and Amtrak think are appropriate budgets. At French construction costs, 124 km of high-speed track with no tunnels, few viaducts, and a mostly preexisting Interstate right-of-way should be about $2.5 billion. Likewise, the cost of 167 km with only 2 km of tunnel and a fair number of viaducts should be less than $4 billion, possibly down to $3.5 billion.
However, in case there’s only enough money for part of the route, construction has to be phased. The Hartford route has no track connections to usable passenger railroads between Hartford and Providence, so the only useful partial construction there is the entire Hartford-Providence segment at once plus electrification of New Haven-Hartford(-Springfield). The I-95 route comes sufficiently close to the legacy track in East Haven and Old Saybrook, giving three segments each of which can be built separately: across the Quinnipiac, from East Haven to Old Saybrook, and from Old Saybrook to Kingston.
Every possible train station on a route deserves an answer to two questions: what is the time advantage gained by skipping it?, and who is served by it?. Stations very close to urban terminals, for example Back Bay, have a very low stop penalty because of low approach speeds, but don’t add much service since people can just ride to the urban terminal. Suburban stations such as Route 128 and even Stamford given necessary track upgrades impose high enough a cost that they should also be skipped by express trains even if there’s a fair number of people who’d use them on the local trains.
Between New York and Boston, there are three stations where the answers to both questions favor express stops: New Haven, Hartford, Providence. With New Haven and Providence, the time cost of serving them is so low given urban curves that the only way to skip them at speed is to build new urban tunnels, which cost a lot of money relative to how much time they save. With Hartford, the situation is the same if all trains go via the inland route that serves it.
However, on some level, the time cost of serving Hartford is 9 minutes, compared with about 2 for Providence. But this is not really comparable, so we can’t just say “9 minutes is too much,” as it would be if a station on a running line imposed a 9-minute stop penalty. If we skip an intermediate station that imposes a time penalty of 4 minutes, the express trains gain 4 minutes but there are still local trains serving it. In contrast, if we go via I-95 we save 9 minutes but have no way of serving Hartford on local trains; trains can branch off north of New Haven and serve Hartford and Springfield at lower speed, but this only connects Hartford to New Haven and points south rather than to Providence or Boston. So we lose something more fundamental than stopping train frequency.
So it’s not enough to say that Hartford should be skipped because it saves the trains 9 minutes. That cost-benefit calculation depends on how important serving Hartford is to people. It’s up to the potential users of Northeast Corridor HSR and the politicians providing the funding to decide whether it’s worth it to connect Hartford with Providence and Boston.
I do not know many people who live in Boston proper. I know about a hundred who live in the Greater Boston area, but only a small minority lives in the city proper, as is of course true in general. I know many people who live in Boston suburbs or in secondary cities like Worcester, but the largest concentration lives in the urban parts north of the river: Cambridge, Somerville, and Watertown. This is true even if I exclude everyone with Harvard or MIT affiliation. In the geek community, Boston proper is where Chinatown is and where the train station is; the social centers are around MIT and Harvard, the jobs seem to be centered in Cambridge as well, and Brandeis graduates often gravitate toward Cambridge and Somerville.
What this means is that I don’t know what people in Greater Boston think about things very reliably. I know the attitudes in Greater Cambridge, or at least the part of Greater Cambridge that goes to conventions. Just as the Providence I inhabited was really a Greater East Side, one in which more people know more residents of Back Bay than of Olneyville, the Greater Boston I inhabited is a specific subculture that’s very active in New England, with specific attitudes that aren’t found elsewhere. For example, support for public transit is quite high, while at the same time enough events don’t and can’t take place in the urban core that people still figure cars are needed, leading to a culture of carpooling.
I keep being reminded by this every time I read pieces by Aaron Renn about attitudes in a city. His latest piece about gentrification is a more subdued example since he talks mostly about the actual effects of gentrification, but the point about people’s attitudes toward it is still there. An earlier piece about Rhode Island mindsets is more indicative. To Aaron, people in and around Providence identify with the state or with their local town rather than with the region. The people I have met are not like that, and often live in southern Massachusetts while still identifying with Providence somehow. For example, one of the Waterfire performers performs in Plymouth and Providence (and Providence is the bigger draw) and lives just outside the census-defined Providence metro area. For another example, I know a recent Brown graduate who is from a Providence suburb of Massachusetts who identifies with Rhode Island and southern Massachusetts, having gone to another college in Providence and to grad school at Brown.
The upshot of this is that it is extremely hard to make any generalization about a city from our own social circles. I live in social circles that are well within Richard Florida’s creative class, but aren’t really what urban leaders seem to care about. I went to a Providence event called Geeking Out once, and it turned out to be about subsidizing smartphone app developers. It’s clearly geeky; it also has no overlap with the geeks I know who teach children how to build robots, or go to fandom conventions. When we talk about cities and urban politics, we never say things like “the city needs to attract more talent.”
But the same difficulty of generalization of course affects the elites as well as people who perceive themselves as normal. If Aaron’s experience talking to urban development leaders is indicative of what they too think, then their social circles also consist mainly of other urban development leaders and their immediate families. There is nothing inherently wrong with that, but there is a real danger of overgeneralizing from an unrepresentative social network. Aaron himself doesn’t do this, but people in positions of power do. The New England I inhabited was a bubble in which downtown Boston didn’t really exist; the Providence that the power brokers seem to inhabit is one in which it is more important to improve transit access to the Jewelry District than to South Providence and Olneyville. I say this as someone who in a year in Providence visited Olneyville once and South Providence never, but because I never saw myself as representative of transit riders, I formed opinions based on where preexisting ridership is and where usable rail infrastructure is and not on gut feeling about where service should go. We all have subcultures, but some subcultures think of themselves as more normal than others, and a few think of themselves as not subcultures at all but as representative of everyone.
In lieu of a real post, I want to discuss a few possible rail projects that are not completely thought-out. By this I mean rail projects that probably have critical constructibility and cost problems, but not obvious ones. They lie somewhere between true trolling – say, transcontinental HSR from New York to Los Angeles – and projects that are difficult and not yet proposed but need to be seriously considered, such as new train tunnels to Lower Manhattan or a Geary subway.
The projects are roughly ordered from most serious to most frivolous. The projects for the Northeast may well be feasible and should be at least considered, and the first was probably originally not done due to agency turf issues. The rolling stock projects are the most speculative – they suggest things to be done by competent rolling stock manufacturers that probably would’ve done them already if they could. The non-Northeastern infrastructure projects are somewhere in between. Make of this what you will. Just, please, do not use any of this as the basis for any alternative proposal, and do not link with a description like “Why have transit agencies not thought of this?” unless you know what you’re doing.
ARC-North: the proposals for cross-Hudson tunnels that connect to Penn Station, including ARC Alt G and now Amtrak’s Gateway, would have the new tunnels connecting to the south of the main intercity through-tracks: ARC goes to the southern tracks, currently used by New Jersey, and Amtrak eventually wants to add tracks to the south. I propose that when they eventually build such a project, they build the new tunnels to the north, connecting to the existing northern pair of East River Tunnels; a connection to Grand Central could then be built from one of the two East River tunnel pairs, the one not used by intercity trains.
Right now, the northernmost tracks have the most access points and the southernmost tracks the fewest. The system would take advantage of the reduction in demand to Penn Station after East Side Access opens. In case the present-day North River Tunnel diameter is too narrow to allow for higher speeds, the new tunnel could then be used (also) by intercity trains at 200 km/h while letting commuter trains go to Grand Central without reducing capacity there.
Northeast Corridor to Market East, on the cheap: a short connection between North Philadelphia and North Broad, similar to that proposed for the Chestnut Hill West Line but used for the Northeast Corridor instead, would let intercity trains serve Market East or Suburban Station, in addition to 30th Street Station. Trains continuing down to Washington would probably not want to use such a connection, as it would slow them down because of the sharp turn in the SEPTA tunnel, but trains continuing on the Keystone Corridor would emerge from 30th Street oriented the right way. Right now trains to the Keystone Corridor have to either reverse direction (as they do today) or use a connection that skips 30th Street Station (as the fastest New York-Chicago trains did in the Broadway Limited era). It could be useful for local HSR trains if there ever were HSR from Philadelphia to Pittsburgh.
Philadelphia Bypass: also on the subject of HSR from New York to the Keystone Corridor, if express trains skip Philadelphia, it would be useful to build a bypass roughly along existing freight routes and I-276, starting at Trenton and ending somewhere between King of Prussia and Exton. The cost may not justify this in terms of cost per minute saved on New York-Pittsburgh (and New York-Cleveland, and New York-Chicago).
Providence Downcity Station: using the East Side Rail Tunnel, trains could continue west to Downcity, and then connect to the legacy tracks by hopping over I-95 in Federal Hill. For commuter trains, an underground station at Thayer Street is necessary. This is a pick-your-poison project in terms of takings: there are tradeoffs between curve radius, i.e. noise, and takings, and also between both and centrality. One option would be a curved station over City Hall Park, which would become the new Kennedy Plaza, and then what is now Kennedy Plaza would be landscaped and turned into the new City Hall Park. Another would go straight west, cutting through Citizens Plaza, and have a station elevated over Memorial Boulevard.
To troll even further, trains could use abandoned trackage starting from East Providence and then go to Fall River (reconstructing more abandoned trackage) and Newport (building new tracks through Bristol and over the Mount Hope Bridge).
Old Erie Line Revival: New Jersey Transit’s Main Line trains do not use the Erie Main Line south of Paterson, which is abandoned, but instead go along the Lackawanna’s old Boonton Branch. The right-of-way for the original Erie line is still intact, and serves the center of Passaic better. It might be useful to rebuild the tracks, which would require viaducts, and realign the Main Line. Service on all lines would probably require too many outlets – not even a dedicated tunnel to Lower Manhattan, combined, could be used for all lines serving that part of North Jersey, so some would have to be severed and turned over to light rail (maybe the Northern Branch) or the subway. The old Erie line is actually the best candidate for being part of a subway extension, since it serves dense communities and has a natural terminus at Paterson, where it would probably have to go underground.
Steinway Tunnel Widening: the Steinway Tunnel was widened from trolley loading gauge to IRT loading gauge when what is now the 7 was built. Since the rest of the 7 is built to the wider BMT/IND loading gauge, widening the tunnel is a useful capacity reliever to spend money on. It’s probably supremely expensive – I’m sure the MTA has studied it in the past; it’s also far from the most crowded Queens-Manhattan crossing point. But the cost may compare favorably with other means of providing extra capacity, and it may also be beneficial to let some Flushing Line trains serve Broadway and some Astoria Line trains serve 42nd Street.
Subway to Burbank: Los Angeles’s Red Line does not go straight north along Vermont to Burbank, but swerves west to swerve more of Hollywood and serves Universal City and North Hollywood on the Valley side of the mountains. Since Downtown Burbank is a major secondary employment center, soon to be served by HSR, why not extend the city’s transit system in that direction? The Orange Line there should be a no-brainer, but more speculatively, the MTA could find money (another ballot measure, maybe?) and program another a subway branch off the Red Line that serves Burbank, with excessive splitting prevented by a new Vermont subway, or even (to troll further) an entirely new line that follows Western south of the mountains.
San Jose – Almaden Street Station: San Jose has a medium-sized CBD, roughly comparable to Providence or Burbank, but Diridon Station is separated from it by a freeway. Since there’s already a plan to spend large amounts of money of turning it into a multi-level train station, which the local technical activists have dubbed Diridon Intergalactic (or Pangalactic), why not also move the station? Trains could go on an alignment like this, elevated over Almaden, on a viaduct dedicated to Caltrain and HSR so that only four tracks would be needed. It would also bypass the current reverse curve between Tamien and Diridon, obviating the need for an iconic bridge. In a realistic, cost-conscious blended plan this is too expensive, but they should at least compare the cost with both a blended plan and the proposed full-fat business plan before rejecting it.
San Francisco – Embarcadero Station: with Transbay Terminal facing every planning and constructibility problem known to humanity, and the current terminal at 4th and King too far from the CBD, why not extend the trains under King Street and then the Embarcadero and build a station near the Ferry Building? Building this close to water is a nightmare, and the curve from King to the Embarcadero may be too sharp, but at least this connects to BART directly and has no station length constraints. On the third hand, the Embarcadero is wide but possibly not wide enough for three platforms and six tracks.
Tilting HSR: tilting HSR trains are either relatively low-speed (the Pendolino is limited to 250 km/h, with a few derivatives capable of a bit more) or relatively low-tilt (Talgos are capable of 180 mm of cant deficiency, and the latest Shinkansen trains have active suspension allowing up to about the same for the E5 Series. However, trains capable of 250 mm cant deficiency and 360 km/h are feasible; this is the main subject of Martin Lindahl’s thesis, which I (and others) have been quoting as a ready source of HSR track standards around the world. That said, probably the only place in the world that needs such trains is the Northeast Corridor, due to its unique combination of long straight stretches, on which very high speeds are possible or could be with minor infrastructure upgrades, and long curvy stretches, on which even major upgrades could not bring up to full HSR standards.
Catenary-free HSR: there’s new technology for catenary-free light rail, which is intended for use in historic city centers with aesthetic opposition to trolleywire. The contactless power supply is buried under the tracks, with each segment activated only when a train is completely above it. Although the technology is still low-speed, it could be useful for HSR. Pantographs generate disproportionate noise at high speeds, and Japan specifically has been squeezing every possible decibel out of low-noise pantographs. Being able to eliminate the pantograph would carry this to its logical conclusion. On the margins, it would also permit narrower rights-of-way, since no space for catenary poles would be needed.
In some American cities, new or proposed transit lines are either core connectors, i.e. city-center circulator streetcars built for development purposes, or far-flung commuter rail extensions with few urban stops. Both are present in Providence, with the South County extension of the MBTA and the Core Connector, but worse circulators than in Providence are proposed elsewhere (for example, in New Haven), and exurb-focused commuter rail with parking lot stations is the standard in most Sunbelt cities and also in Massachusetts. At first I thought my opposition to both was just a matter of wonky support of a specific stop distance and service pattern that falls in between those two extremes, but recently, after attending Providence urbanist blogger meetings and also rereading old threads about New Haven, I realized there’s a political and social dimension to all this.
Recall that old American cities have a donut-shaped income distribution: gentrified in the center, poor in most other urban neighborhoods and inner suburbs, and middle-class to rich in most suburbs. Those two forms of bad transit are specifically built to cater to the rich parts of the metro area, and ignore the poor parts. The problem, of course, is that the poor parts are precisely where transit ridership is concentrated. People in the gentrified cores of smaller cities can walk; people in the suburbs own cars, and those cities have too many roads and too much parking for buses to be an even semi-reasonable alternative.
In Providence, as I recently brought up, the busiest buses follow Broad and North Main, and serve working-class and poor populations. The same is true in New Haven: the busiest line by far runs on Dixwell, connecting the Yale student ghetto, the in-between poor neighborhoods, and the strip malls in middle-class Hamden. So what service addition does a study by the South Central Regional Council of Governments (SCORAG) propose? Naturally, a circulator connecting Union Station with the New Haven Green. You could chalk this up to a belief in systemwide upgrades over building a few high-performance lines, but many outlying bus stops have no shelter, and the study says nothing about that.
When Peter Brassard first pitched the idea of a local rail shuttle service in Providence and its inner suburbs to us privately, the observation one of us made (I think it was Jef Nickerson, but I’m not sure) is that it would invert the usual relationship between infrastructure investment and income. This is mostly accidental – the mainline serves Olneyville and Pawtucket but not the East Side. But something like this is more likely than not when the focus is on serving reasonably dense neighborhoods and perhaps inner-suburban malls outside walking range.
The same is true of what I believe to be the most promising rail shuttle service in New Haven – namely, a service using the Farmington Canal Trail, which runs about 200 meters east of Dixwell, and could be reused by light rail reaching downtown New Haven on city streets or rapid transit connecting to the mainline with a very short tunnel or trench. With a stop spacing of a little less than a kilometer, modern rolling stock could average 35-40 km/h in service, double the speed of the current bus.
I suspect part of the bias against such service comes from the belief that building ten kilometers of light rail is expensive. Because there’s an implicit hierarchy in planners’ mind between services, they think a downgrade is an automatic cost saver, even when it’s not – for instance, when a bus on an abandoned railroad costs far more than most rail reactivation projects do. One of these mantras is that commuter rail infill is less expensive (and then they build infill stations at $100 million apiece, strategically located away from the intersection with the main bus corridor). As a rule of thumb, each of these downgrades just raises unit costs because of various overbuilding schemes until total cost is the same as if they’d built regular urban rail, but the benefits are much lower.
But it’s more than a technical bias; it’s also political bias. The Core Connector is explicitly a development project. It may even be a successful one, if it convinces local power broker Colin Kane to drop plans for building 7,000 parking spaces in the Jewelry District, as described in a recent paywalled article in Next American City. Development projects like this never go to extant low-income neighborhoods, unless there’s an explicit effort at gentrification, and usually locals protest against the displacement; neglect is much easier and less controversial than redevelopment.
The technical and political biases merge in one of the less challenged cost-effectiveness metrics, the cost per new rider. Although it’s presented in neutral terms – the cost is compared to the predicted total transit ridership if the project is built minus the predicted total if it is not – the results privilege adding choice riders (that is, those who already own a car and drive to work) over retaining existing riders. Although transit revivals happen, most of the world’s transit cities built out their systems before most people got cars, and people simply kept using transit instead of buying cars even as they moved into the middle class. Portland may have about the same metro area transit mode share as before it built light rail, but other cities of similar age lost ground and have even lower transit use.
It’s tricks like ignoring retention that lead Boston to downrate replacing the southern half of the Silver Line with light rail on its list of possible projects even though it would be very cheap by US standards per rider, and rate new commuter rail branches well beyond the continuous built-up area as more cost-effective. The rail bias factor implied by the computation for new riders is less than 0.5%: 130 new riders against 34,000 existing ones. A Transportation Research Board analysis finds the rail bias is in the 34-43% range. I suspect that if the Silver Line served richer areas than Roxbury, Boston would use a more reasonable rail bias than 130/34,000, bringing down costs per new rider by two orders of magnitude. New York went ahead with Second Avenue Subway; it is undoubtedly the most important subway project in the region, but the next best corridors, e.g. Utica, serving less chic neighborhoods than the Upper East Side, are ignored.
The technical reason to build urban rail a certain way – own-right-of-way, stops roughly every kilometer within the city, etc. – is of course separate. Technical characteristics do not tell you which neighborhoods to serve, not without first looking into existing demand patterns. It is just fortunate that New Haven has a right-of-way closely paralleling Dixwell, and unfortunate that Providence has none paralleling Broad. But the income donuts, and more generally the connection between density and old industrial development that is usually working-class (since gentrification in such cities is within walking distance of the core rather than within transit distance), have certain social implications. The most annoying to the planner and the government official is that they must invest in poor neighborhoods as they are, and do not have a special reason to try to foist change upon them.
Or they can just build core connectors for the cities and park-and-ride extensions for the suburbs. The FTA will fund these no matter what; its cost-effectiveness metrics are biased that way to avoid having to send every penny it has available to a few expensive but high-ridership lines such as Second Avenue Subway. The developers will like them, because of real or imagined property value benefits. The state will like them – state governments are dominated by suburbanites and urban developers and view transit as pork rather than as useful spending based on ridership metrics; Rhode Island is much likelier to find support for development in the Jewelry District than for boring rail lines in already-developed Providence neighborhoods. It’s a win-win for everyone except the riders, and they don’t count.
While trying to come up with a good proposal for upgraded buses or streetcars in Providence, I tried to base route decisions on RIPTA’s most frequent buses. But as it turns out, there’s a substantial difference between the most frequent and the busiest routes, and existing policies toward investment do not reward high ridership at all.
By far the two busiest lines in the state are routes 11 (Broad Street), with 6,500 weekday riders, and 99 (North Main to Pawtucket), with 5,200. Those are also the two most frequent, with 10-minute peak and midday service, and are usually interlined. This is the only case in which frequency matches traffic: of the next batch of busiest routes – 20, 22, 56, and 60, each with about 3,000 weekday riders – only the 56 has 15-minute off-peak service, the rest ranging from 22 to 35, with the 20 and 22 having 22-23-minute frequency even at the peak. Several less busy lines have 20-minute all-day service, and the frequent network, which uses a 20-minute weekday off-peak standard, looks different from the highest-traffic network.
However, previous and proposed development-oriented transit, including the fake trolleys and now the streetcar, avoid even the 11 and 99. The fake trolleys are distinguished in branding, 20-minute frequency even on weekends and in the evenings, and consistent interlining across Kennedy Plaza. The 92 fake trolley runs from the East Side to Federal Hill without changing its number, but regular buses, including the 11 and 99, change their route number at Kennedy Plaza, and that’s if there’s a consistent route they interline with at all. (When Jef Nickerson pressed RIPTA on this issue, RIPTA said it wants to preserve flexibility.) Likewise, the streetcar is a city-center circulator, and ideas for where to extend it afterward avoid Broad Street and North Main; local transit activists I have talked to believe the preference is for Broadway, a wide street hosting two routes (27, 28) that have 4,500 weekday riders between them, still less than Broad. (The alternative route in the same direction, Westminster, has 3,500 on its two buses, but the difference comes from the routes’ respective tails west of Olneyville Square, and the segments along Westminster and Broadway look about even.)
This is not to say that the state spurns the busiest routes. After the previous Governor vetoed it six times, Governor Chafee recently signed a bill to provide bus signal priority on the busiest lines. The brand for this is called rapid bus. At best, this shows the state thinks that rich people on the East Side and the Federal Hill gentrifiers, and soon the Jewelry District gentrifiers, prefer to ride a service that’s not called a bus, even if it is one. At worst, it points to skewed priorities: the streetcar is explicitly a development tool, and much more expensive than clearly posting schedules at the top end of the bus tunnel and rearranging schedules to provide constant headways within it.
A related issue is the ability to railstitute bus routes. Among all the busy routes, route 11 is among the hardest to replace with commuter rail. Peter Brassard’s urban shuttle proposal and my Woonsocket regional rail proposal use existing railroad lines. Arguably, this could take over the longer-distance functions of the 99, whose demand primarily comes from Pawtucket rather than North Main in Providence. However, the 11 is not paralleled by any rail line. This makes it the most important corridor for any upgrade. Alternative routes, such as continuing the existing streetcar proposal farther south, do not capture the local demand on Broad, which is of moderate intensity everywhere along the corridor. The distribution of demand on Broad is linear, which is less the case for other routes, which connect various anchors spaced farther apart.
It’s not normal for the relationship between traffic and frequency to be so weak. (In New York, busy routes that aren’t frequent by a 10-minute standard are the exception, and are very close to making the cut, e.g. the B8 and Bx39 run sometimes every 10 minutes midday and sometimes every 12). RIPTA needs to be asking itself why some routes are overserved and others are underserved.
But more importantly, the city and the state need to ask themselves why they’re building special branding as not-a-regular-bus around routes that aren’t even the ones that most need it. The fake trolleys get emphasized and specially colored on the map. It’s RIPTA’s fault that the interlined buses aren’t consistently signed, but all of the investment decisions are on the city and the state. Even if it’s necessary to build a streetcar to the Jewelry District and the hospital, why not say that pending additional funds the city will extend it toward and then along Broad? The alignment wouldn’t be any more awkward than that already proposed, and it would only miss a relatively short segment of Broad.
Peter Brassard’s proposal for a very frequent-stop mainline train in Rhode Island received comments both here and on Greater City, dealing with issues from rolling stock to station choice to scheduling. Some are fairly trivial, some aren’t. The upshot is that the project is technically feasible, but requires political head-bashing, especially with regards to scheduling.
First, the easy part: if the line is only to run between Central Falls and Warwick, then the rolling stock should be electric; this both improves performance and eliminates a political bottleneck, because the EMU market is larger than the DMU market, and in case FRA regulations do not change and obtaining a waiver is too expensive, there are M8s ready to use. The M8s are heavier than is ideal, but their performance is to my knowledge imperceptibly worse than that of noncompliant trains in the speed range appropriate for the short stop spacing, up to about 100 km/h.
Scheduling is the problem, because there has to be track sharing with something. The line is three-tracked: there are two tracks for Amtrak, also used by the MBTA north of Providence Station, and one track for freight. The line used to be four-tracked, but was reduced to three tracks in the 1990s in order to widen the track centers and allow the Acelas to tilt. Further reduction in track centers is not acceptable: at 4 meters (more precisely 13′) the distance is shorter than the standards for greenfield construction in Europe and even Japan. Track center standards are laxer on lower-speed segments, as the trackage through Providence is, but tilting becomes unsafe for an Acela-wide train. (The Pendolino is 37 cm narrower than the Acela.)
The alternative is to slightly widen the right-of-way at certain overpasses to allow four tracks, for a minimum of 20 meters with 4-meter track centers; some work, including widening, is already required to make room for platforms, and many of the most constrained locations, such as Olneyville at 18 meters, are station stop sites. It’s this construction that would most likely be the bulk of the project cost. At much lower cost, it would also allow electrification of the full corridor, making EMUs a feasible rolling stock choice for the local trains.
With four tracks, the question becomes, what regional rail should share tracks with. The choice is between intercity trains, which are currently slow but could be sped up, and freight trains. Both require political maneuvering, because neither Amtrak nor the Providence and Worcester has operating practices that are compatible with punctual passenger service. (Amtrak is more easily reformable, but an Amtrak that’s been so reformed is an Amtrak that runs trains much faster on the Northeast Corridor, increasing the regional/intercity speed difference).
I contend that it’s actually more correct to share tracks with freight. The sharpest curves are at stations, and so no superelevation is needed, but even if it were, allowing 100 km/h passenger trains could be accommodated with minimal freight train cant excess (about 25 mm at 50 km/h). More importantly, freight and local passenger rail have similar average speeds. The speed profile is different – freight is steady and slow, local passenger rail attains higher speeds but makes frequent stops – but when headways are long enough, this is not a problem.
On page 46 of the Providence Foundation study on a similar passenger line, we see that there aren’t many freight trains, so headways are determined by passenger trains. The freight schedule on page 48 of the same study suggests that freight and passenger train speeds would be very similar. It has trains doing Pawtucket-Warwick in 23 minutes; modern EMUs with a top speed of 100 km/h (losing 45 seconds to each station stop) and making the proposed stops would do the same in 25 minutes, with 7% padding. The local passenger train is a hair faster than the freight train on the Providence-Pawtucket and Cranston-Warwick segments, in both cases by less than a minute, and a bit slower on the Providence-Cranston segment, where station spacing is denser. This is close enough that I believe that 15-minute passenger train frequency is no barrier to track sharing. Potentially even 10-minute frequency can be accommodated. It requires freight trains to be somewhat timetabled, but they’d have a window of several minutes to enter between each pair of successive passenger trains, and missing their window would not delay them by more than 15 minutes. There is, then, no technical barrier to sharing tracks with freight.
The alternative, sharing tracks with intercity trains, is more dubious. Although less construction is required, the speed difference is larger. Instead of taking 23 minutes between Pawtucket and the airport, optimized intercity trains would take 8:45, including padding and a station stop at Providence. They can pass local trains at Providence, at the cost of slowing them down by several minutes while they wait to be overtaken, but even between Providence and the airport, travel time would be 5 minutes for intercity trains and 17 for regional trains.
If there’s four-tracking in Warwick, or two stops are dropped, then it’s tight but doable. Otherwise, it’s not; 12 minutes is too long a window for 15-minute service. It would require an extra terminating track at Warwick, but that would be needed anyway. The problem then is that local Rhode Island trains and MBTA trains would interfere with each other at Providence because both would dwell at the station for too long.
Interlining the two services and having MBTA trains make local stops in Providence is possible, and in conjunction with the two-overtake schedule for Boston-Providence naturally yields a three-overtake schedule. The problem is that the more overtakes there are the more reliability suffers. If an hourly freight train misses a window and needs to be delayed 15 minutes, it’s no big deal; if the goods couldn’t take a 15-minute delay, the train would be sufficiently punctual to make the window. If a passenger train misses a window, it requires the train behind it to slow down and this is not recoverable if the schedule is so tight.
When it’s unavoidable it’s best to just invest in running trains on schedule, but in this case a three-overtake schedule is avoidable. Thus track-sharing with freight is the correct option, leaving intercity trains to have a track that’s entirely theirs south of Providence, as this shuttle concept would almost certainly take over Wickford Junction service if necessary. It conveniently also allows higher regional rail frequency should the need ever arise, and because the scheduling is loose makes it easier to shoehorn another line into this system.
This is a proposal by Peter Brassard, who comments here and on Greater City: Providence. It was published on Greater City first, and is mirrored here as the site is experiencing server problems.
Rhode Island’s commuter rail service as currently conceived may not be conducive to encouraging ridership. Distances between existing and proposed stations are too far. Much of the focus has been on extending the system further into low-density suburbs. For Rhode Island commuter rail to succeed, more needs to be done to take advantage of existing walkable urban neighborhoods that have a high potential for passengers. Some of these areas have large amounts of commercial/industrial space or development opportunities. Due to Downtown Providence expansion, the rail system will be challenged, as long as there’s no internal downtown high-frequency transit, such as the proposed Core Connector, to directly link rail passengers to the far reaches of downtown.
Rhode Island’s commuter rail doesn’t capitalize on density variations and neighborhood assets of the Providence area. If Rhode Island’s commuter rail functioned as a rapid mass-transit system, besides increasing the number of passengers, it would help to revitalize and expand development opportunities for neighborhoods along the rail line. The implementation of medium frequency shuttle train service within the Rhode Island instate rail corridor would offer predictable headway times at regular intervals that could operate in addition to MBTA commuter and Amtrak trains. Air and intercity train travelers, commuters, and the general public would greatly benefit from this level of service.
A variation to a commuter rail or shuttle train is the German S-bahn or French RER or San Francisco’s BART. An S-bahn type system is usually the same as commuter rail in suburban areas, but differs when it’s within the central urban core, where it has characteristics of a subway or metro. Usually stations within the core zone are located close together at quarter- to half-mile subway station distances and schedule headway times typically fall somewhere in the middle of commuter rail and subway schedules. Depending on the city, central core rail infrastructure can be underground or at grade utilizing existing rail corridors. A hybrid of a shuttle train and an S-bahn might best for Rhode Island.
One way to organize Rhode Island’s rail system would be to create different station tiers allowing for various levels of service and investment in station infrastructure. Tier service levels could be thought about as intercity or express (Amtrak), regional or limited (MBTA), and local (RI Shuttle trains). Shuttle trains should be able stop at all stations and MBTA trains should have stops at major commuter and Amtrak stations. The hours of operation of a shuttle train should extend to weekends and late evening at all stations. Because a shuttle train schedule would be frequent and regular, it would relieve the need to increase the number of MBTA commuter trains for Rhode Island transit needs or having to extend MBTA weekend service south of Providence.
Shuttle train stations should require a lower level of investment. Platforms could be adjacent to the freight track. Priority should be given to constructing affordable shuttle train infill stations without automotive accommodations. An infill train station could consist of as little as a single high-level concrete platform with stairs, handicapped ramp, railings, partial canopy, lighting, and signage. Some stations might require an elevator instead of a ramp for ADA access. Without the land acquisition and construction costs for parking, drop-off facilities, station buildings, or pedestrian bridges, the cost range for a barebones single 300-foot long infill platform with modest accessories should cost between $500,000 to $1-million. A typical 900-foot long platform would be roughly $2 to $4-million. Because of increased service frequency, a shuttle train could have fewer cars and utilize shorter platforms that could be extended in the future, reducing the initial infrastructure investment. Shorter trains and platforms would allow the system to develop incrementally as ridership increases.
Infill stations should mostly be located within high-density urban neighborhoods where people can either walk or take existing bus transit to stations with limited or no automotive infrastructure. To optimize use by pedestrian’s stations should be designed so that they would have direct access from sidewalks of major streets with bus routes. Major streets and bus routes can act as siphons to funnel potential passengers from adjacent neighborhoods to stations. Bus routes that intersect the rail line corridor would effectively extend the passenger capture area of a walkable neighborhood. A passenger capture area would be the total population that’s within less than a 12-minute walk and/or a 7-minute bus ride to a train station.
Infill stations could become catalysts to renew employment opportunities in older industrial neighborhoods, reinforcing economic development. Less advantaged people from urban neighborhoods would be able to commute without needing a car. A series of stations served by frequent shuttle train service would create true rapid transit for Rhode Island passengers to quickly reach jobs or homes in adjacent cities or distant neighborhoods, not possible with the bus system. The increased use of commuter/shuttle trains would reduce traffic congestion and lower air pollution. Opportunities to concentrate additional employment and population around stations would help to limit the expansion of suburban sprawl.
There is historic precedence of having closely situated train stations within Providence documented on city maps from 1918. (Link 1) (Link 2) In addition to Union Station, previous train stations existed at Atwells Avenue, in Olneyville at Westminster Street (northbound) and Dyke Street (southbound), Cranston Street, and in Elmwood. There are likely other forgotten stations outside of Providence. I remember being told as a boy that my great-grandfather would regularly take the train to Providence from Woodlawn in Pawtucket. As late as the 1960s there were the ruins of a wooden stairway leading down to the tracks at Lonsdale and Mineral Spring Avenues.
Currently proposed urban infill stations are 300 Barton Street in Pawtucket, Olneyville, and Park Avenue in Cranston. Other potential infill stations could include Central Falls and in Providence at Reservoir Avenue, Cranston Street, Atwells Avenue, and Charles Street. Also Hunt Street, Mineral Spring Avenue, Branch Avenue, Dean Street, Union and Roger Williams Avenues could be considered. Suburban industrial infill stations could be built toward the northern end of Jefferson Boulevard and Davisville/Quonset though these locations might require additional bus shuttle service. There would be infill station opportunities with the Lincoln and Cumberland villages along the Blackstone River, for when train service would be extended to Woonsocket. A station at Route 116 with elevators and escalators reaching to the Washington Highway bridge deck would allow passengers to access buses to Lincoln and Smithfield’s office region.
For details, see this map, overlaid on a RIPTA bus map. It shows potential shuttle train stops within walkable urban neighborhoods. Distances between stops are generally at half-mile intervals.
Olneyville’s potential for a high number of passengers should be a top priority. The current proposal for Olneyville locates a platform on Harris Avenue, away from the Broadway and Westminster Street bus routes. This location was likely chosen because construction costs would be low. A direct access walkway/ramp to the Harris Avenue platform from Broadway and Westminster should be provided, which could be developed through easements with the abutting commercial property and elderly high-rise south of the proposed platform. From looking at census tract data and existing bus routes the passenger capture area for Olneyville is probably the highest with roughly 28,000 people who could reach the station in less than a 12-minute walk and/or 7-minute bus ride. If only 5% of that population used the train that would equal 1,400 people or up to 2,800 passenger trips per day. Olneyville also has over a million square feet of commercial/industrial space, much of which is vacant or underutilized, plus vacant land for new development within walking distance from the station location.
RIDOT has two alternatives, option “A” and option “B,” for a Pawtucket/Central Falls infill station. Pawtucket officials and RIDOT favor the 300 Barton Street location for a Downtown Pawtucket station. Fewer people would be within walking distance of this station, but bus service would expand its passenger capture area of roughly 13,000 to15,000 people. The lower western quadrant of Central Falls would be walkable to this station. Development opportunities would be great for Downtown Pawtucket. RIDOT/VHB’s proposed 2009 Option “A” plan would be preferable, as both proposed station platforms would have direct access to Dexter Street’s sidewalks and buses without requiring a special drop-off circle for buses within the parking lot. Option “B” should be rejected as it isolates the station creating a condition favorable to automobiles and access to Dexter Street would be indirect and circuitous for pedestrians, which might limit opportunities for smart growth development in Downtown Pawtucket. The current plans to include a parking lot and vehicle drop-off area, though expensive should probably remain, since Pawtucket is a regional center and would be a major MBTA station. In the future the current proposed parking lot could be upgraded to a multi-level structured facility.
In Central Falls a rail platform located near Sacred Heart Avenue would serve the eastern half of Central Falls and some of Pawtucket north of downtown. Roughly 8,000 people would be within walking distance of this station, which would not have pedestrian overlap with the proposed Barton Street Station in Pawtucket. The adjacent Central Falls neighborhoods that would benefit are among the poorest and highest density communities in the state. This station location should be considered in addition to Barton Street.
Other infill station possibilities include a Cranston Street station, which would have a passenger capture of roughly 13,000 to 15,000 people in Providence and Cranston. The Huntington Industrial Park on Niantic Avenue has about a million square feet of commercial/industrial space, some of which has been converted to offices. Not that it’s necessarily practical to rebuild the entire district, but the Huntington Industrial Park is built-out to a small fraction of what is permitted by current zoning. The Corliss Industrial Park at Charles Street has similarities to the Huntington Industrial Park. A Charles Street station would have an approximate capture area of about 15,000 to 17,000 people. Passengers would be more reliant on arriving by bus from the North End-Charles Street area, Wanskuck, and Elmhurst, since the potential for passengers walking to the station might be more limited.
Reservoir Avenue near Adelaide would have a capture area of about 14,000 to 16,000 people in Elmwood and the Reservoir Triangle extended by bus to parts of Cranston, South Providence, and the West End. An Atwells Avenue station might only have a capture area of 5,000 to 6,000 residents, but a station platform at this location would be a critical link to Atwells Avenue restaurant/retail tourism district, as well as, commercial and industrial space in the Eagle Square vicinity and residential neighborhoods in the Valley area, parts of Federal Hill, Lower Mount Pleasant and Olneyville. A Cranston station located at or near Park Avenue would have a rough capture area of 6,000 people from Cranston, South Elmwood, and Warwick. If a Park Avenue bus route were reinstated for the full length of the avenue, the station’s passenger capture area could be further expanded. This location would likely be a major MBTA commuter station and require automotive access and parking facilities.
To justify the construction costs for the TF Green and Wickford commuter rail stations and parking facilities, there should be as many commuters destined for Providence as for Boston. It is possible for commuters to access distant employment areas within the Boston/Cambridge area because Boston’s subway extends the reach of commuter rail stations. The expanded Downtown Providence area will be handicapped as several of the city’s employment areas are beyond reasonable walking distance and underserved by bus transit. It’s essential to build at least a portion of the Core Connector to make Providence Station viable as a destination commuter rail station.
Maximum interconnectivity to multiple stations with a large potential passenger base is the key to creating a robust rail system. The current blueprint for Rhode Island commuter rail is limited. To revive older neighborhoods and improve the state’s economic base, the rail system should serve more than just Providence and Boston commuters and intercity train travelers. Providing a handful of expensive commuter rail stations, most of which in low-density suburbs, is not enough to substantially increase commuter train ridership and insure the success of the system. It would have to be confirmed, but it’s likely that between Central Falls and Cranston there are 100,000 people that could reach the rail line by a short walk or bus ride.
It may be unconventional to propose constructing inexpensive infill train stations geared toward pedestrians and bus riders without parking, who would be served by shuttle trains, but it would transform Rhode Island’s rail system into rapid mass-transit, as well as, commuter and intercity rail. Besides being economical, urban infill stations could be built quickly. Since platforms are relatively low cost and there’s a present need to improve the regularity of train service between Providence and the airport, rather than spending years on studies, conducting a pilot program where a few or several urban infill stations could be built would be worth testing. All passenger types would benefit with this truly competitive alternative to driving within the core metro area. The passenger base for RIPTA buses would be reinforced and expanded, as would MBTA commuter trains. There may be objections from Amtrak and the MBTA or others regarding close proximity of stations and frequency of service. Since Amtrak schedules are on one- or two-hour intervals and MBTA trains run approximately on the half hour at weekday peak and less frequently at other times, urban infill stations and shuttle train service operating mostly on the freight track shouldn’t interfere with either agency. The advantages of developing a rapid-transit rail spine for Rhode Island’s people and economy would outweigh any objections.
The headline numbers for how much federal spending each state gets per federal tax dollar it sends to Washington come from the Tax Foundation and are almost a decade out of date. However, using IRS numbers for tax receipts per state, and QuickFacts’ numbers for federal spending per state and county, we can construct the numbers by state as of 2009. The picture is similar to the old numbers – the North subsidizes the South, as one would expect as the North is richer and also has a higher cost of living.
What I didn’t expect is that Rhode Island would get only 77 cents in federal spending per dollar of taxation. More precisely, in 2009 it paid $10.9 billion in taxes (more than richer states of comparable size, such as New Hampshire) and got $11.4 billion in spending; but the country as a whole ran a large deficit, and so if we divide 11.4/10.9 by the ratio of federal spending that actually came from taxes, we get 0.77. This was going on while the state ranked near the top in unemployment, and for a while, early in the recession, led the nation. The other high-unemployment states got much more than 77 cents on the dollar: California got 92 (up from $0.79 in 2004), Nevada $1.06 (up from $0.73), and Michigan $1.20 (up from $0.85); Florida, which was also hit hard, got $1.21, up from $1.02.
I have no explanation for this. Connecticut and Massachusetts, both richer than Rhode Island, do not get this little. I thought it might be because Rhode Island is a large daytime job gainer – it is one of the top states in percentage of workers who commute in from other states because of all the Providence suburbs in Massachusetts – but North Dakota is another such state because of Fargo’s Minnesota suburbs, and it got $1.60 in spending per dollar of revenue.
Update: Quickfacts decided to stop putting out the federal spending statistics. Here are numbers from 2010, which seem to be in a permalinked format. In 2010, Rhode Island got $11.8 billion in spending and paid $10.5 billion in taxes, which works out to 81 cents on the dollar, again after adjusting for the federal deficit. North Dakota got $1.47. See spreadsheet here with numbers for each state.
