Regional Rail for New York: What Can Be Done Now

MTA Chairman Joe Lhota recently proposed to through-route commuter rail lines in the New York area, as was proposed in the past by the RPA, the Institute for Rational Urban Mobility, and more recently myself. Lhota proposed other, less flashy ideas for integration, including better track sharing at Penn Station and lengthening platforms to accommodate 10-car trains. Although a network that looks like my proposal should still be the goal for the next 20 years, there are several things that can be done in the very short run. None is do-it-tomorrow immediate, but neither does any require very difficult modification of equipment or organization or significant infrastructure investment. Most should not require extensive studies.

Note that this is not a wishlist of the most important commuter rail reorganization projects in the region. Many of those reorganizations do not have anything to do with interagency integration, and are therefore not included. Only projects that are very cheap and would come from or benefit integration are on this list.

1. Integrated ticket machines at Penn Station. This requires the physical tickets on New Jersey Transit to look like those on the LIRR and Metro-North (and thus some modifications to the fare barriers at Secaucus and Newark Airport), and some reprogramming of ticket machines, but no change otherwise. Ideally a ticket from (say) Hicksville to Newark should cost less than the sum of tickets from Hicksville to New York and New York to Newark, to encourage reverse-peak traffic, but strictly speaking the discount is not needed. Amtrak and commuter rail machines should also be integrated, though the physical tickets can still be different if switching over is too hard.

2. Integrated concourses at Penn Station. This means treating the upper and lower concourses as belonging to all three railroads. This requires Amtrak to give up its single-file queuing and accept that people already can walk around and get to its trains from other railroads’ turfs. Trains should be announced on all concourses, and all access points to a platform should be clearly signed with the next train’s type and schedule.

3. Timed transfers. Although a clean integrated timetable is impossible, because trains interline on some inner segments to increase capacity, a partial version is still possible. What this means is that, with hourly off-peak service on each branch, Morris and Essex trains should arrive at Penn Station just before the hour, as should one of the several hourly trains on the New Jersey side of the Northeast Corridor, and then two or three branches going to the east (say, to New Haven and Port Washington, and on one additional LIRR line for service to Jamaica) should leave just after the hour, with the tightest connection done cross-platform. This would make trips from New Jersey to JFK and from Long Island to Newark easier, and the choice of services to participate in the system should be consistent with even spacing on interlined trunks.

4. Modification of rolling stock. Metro-North’s M8s can run under 60 Hz catenary and third rail, but unfortunately not 25 Hz catenary; as lower frequency requires a larger transformer, modifying the trains to run on the New Jersey side of the Northeast Corridor may be too hard in the very short term (though not in the medium and long terms). However, NJT’s ALP-46 locomotives and Arrow EMUs can run on 12 kV 25 Hz and 25 kV 60 Hz catenary, and thus modifying them to run on Metro-North’s 12 kV 60 Hz catenary is easy, allowing them to run from the NJT network to the New Haven Line. Unfortunately, because locomotives accelerate more slowly than EMUs and the Arrows are quite old, they do not have very good performance for short-stop service, for which through-running is the most useful.

5. Voltage change on the Northeast Corridor’s New Jersey side to 25 kV 60 Hz. This voltage change was done to the Morris and Essex lines and much of the North Jersey Coast Line. It is somewhere on Amtrak’s wishlist of projects, but I do not know how high it is. This allows M8s to run through, ensuring the better rolling stock is available for the service that needs it the most. It may possibly be bundled with Amtrak’s installation of constant tension catenary south of New Brunswick to reduce costs. Since this eliminates the need for 25 Hz transformers in the future, this meas future NJT rolling stock would be lighter.

6. Depending on 4-5, rolling stock sharing along interlined services. In practice this means M8s on local Northeast Corridor services, which would also allow adding and serving infill stations in New Jersey (for example, more regular service to North Elizabeth, and perhaps a station at South Street in Newark), and Arrows and locomotives on express services from Penn Station and New Jersey to New Haven.

7. Platform raising on the North Jersey Coast Line and the Morris and Essex lines, if service using M8s rather than Arrows is desired. Because of the voltage, it’s actually easier for M8s to serve the Morristown Line other than their inability to serve low platforms: it would only require 8-21 km of reelectrification rather than 88-101. The Morris and Essex lines also have a more inner-suburban distribution of ridership than the Northeast Corridor Line, which gets most of its ridership from more distant stations, and this makes them in one sense better-suited for through-service. (In another sense, the Northeast Corridor is better, since it serves downtown Newark, a secondary CBD that draws some commuters from suburbs and boroughs east of Manhattan.)

It is my belief that all of the above, possibly except #5 and #7, are feasible within months or at worst a very small number of years, and would not require additional environmental work. Even #5 and #7, which are more expensive, are still close to two orders of magnitude cheaper than a full through-running plan with new tunnels serving Lower Manhattan.

The medium term is more expensive – perhaps an order of magnitude less than the full program rather than two – and would include further modernization, allowing full through-service on every line and more efficient equipment utilization. It can also assume friendlier regulations, which a snap integration cannot, and this in particular means better rolling stock in the future and higher speeds even with existing rolling stock. Clockface schedules and frequent off-peak service would allow planning infrastructure repairs and upgrades around specific schedules. For example, the current local Stamford-Grand Central schedule is 1:06, but an express train I recently took from New Haven came to Grand Central more than 10 minutes ahead of schedule, suggesting excessive padding; minor upgrades should allow an M8 to do Stamford-New York in an hour minus turnaround time making local stops, and more ambitiously New York-New Brunswick in 45 minutes minus turnaround time.

Lhota can’t do much in the long term, because this requires an enormous investment into concrete, a political decision and a longer-term one than Lhota’s term as MTA chair. However, he can both implement the above seven points within his term, and also set in motion various work rule reforms and small-scale capital project planning and apply for the requisite FRA waivers to permit the medium-term reforms to succeed.

Followup on the Providence Regional Rail Shuttle

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.

Netroots Nation and How the 99% Talk Hurts Consensus

For the first time since 2006, I went to Netroots Nation, as it’s held in Providence. There was one panel about public transportation, entitled “Saving Public Transportation,” whose speakers included Larry Hanley, who dominated the discussion; a moderator; and three political activists: including a local union leader, a Sierra Club representative, and a state legislative candidate who Greater City is supporting. The discussion focused on preserving bus operations rather than on expansion – in fact Hanley made the point that agencies expand capital while cutting back service because the federal government only pays for capital rather than operating funds.

Since the panel was entirely political, and dealt mostly with funding issues, when it was time for questions I asked about the saddling of transit agencies with highway debt; I specifically mentioned Massachusetts’ putting Big Dig mitigation debt on the MBTA. I wanted to see if the panelists would say anything about mode shifting or about the relative power of highways and transit.

Instead, Hanley, who took the question, ignored what I said about highway debt, and instead answered about refinancing debt at lower interest rates, as issue his union is harping about. In reality, according to his union’s own figures, the MBTA could save $26 million a year by refinancing debt; for comparison, its deficit this year, which it plugged with service cuts and a large fare hike, was $163 million, and its total debt payments in 2006 were $351 million, of which $117 million came from the Big Dig. Although the parts of this debt that are not from the Big Dig come from true transit projects, those were voted on by the state legislature, rather than by the MBTA; transit’s low position in the transportation funding food chain is thus responsible for 13.5 times as much money as could be extracted from the banks.

So at first pass, Hanley was pivoting to an issue he was more comfortable talking about, which happens to involve a fraction of the amount of money in question. But at second pass, something more insidious happened. Instead of answering a question about transportation priorities and getting state governments to assume debt they’d unfairly loaded onto transit agencies, which would require clashing with other departments with their own agendas, Hanley preferred to shift blame onto banks. He did not include figures during the panel and so I could not know he was talking about such a small amount of money; his explanation for focusing on the banks is that the MTA renegotiated deals with contractors to get lower prices, so it should do the same with the banks.

And after thinking about this, I realized how it shows exactly how despite appearances, the “We are the 99%” slogan is the exact opposite of any sort of democratic consensus. It silences any notion that there are different interests among the 99%. The auto workers and Providence’s carless residents are both members of the 99%; they have diametrically different interests when it comes to transportation. But in the Grand Struggle, the 99% must be united, and thus the leaders shift any discussion to the common enemy, no matter the relative proportions of the amounts of money in question.

After Scott Walker’s win, Matt Yglesias wrote that different industries have clashing interests just as much as labor and business do. But even within the framework of fighting big business’s influence, two of the most influential opposing interest groups, the union movement and small business, have different interests and are hostile to each other. Dean Baker wrote in The Conservative Nanny State that small businesses are being coddled because they pay lower wages and benefits on average; in general, the American union movement has not organized small businesses and supports the businesses it has already organized, and is hostile toward new companies, which are usually non-union. Small business in turn is hostile toward regulations on wages, starting a business, and so on.

The 99% framing papers over all of that. The voices that dominate the protests believe themselves to be the true representatives of 99% of the population, and by implication their own issues to be the most important. Other issues are subsidiary, or outright distractions from the primary needs. Any movement that claims to represent everyone is not consensual but nationalistic, and just as nationalism requires the elites to declare a certain archetype to be Real Americans (or Britons, or French) and everyone else to be one of many negative stereotypes, so does this 99% framing require movement leaders to coopt or downplay other groups’ issues.

Consensus comes from clashing points of view. The Swiss Socialists are farther left than what is considered serious liberal opinion in the US, and the Swiss People’s Party is about as far right as the Tea Party; they and the centrist parties are more or less in a grand coalition. The consensus comes from the realization that no single faction will ever dominate, and thus the best it can do is distill how it can advance its stated goals (poverty reduction, smaller government, greater national cohesion, etc., depending on the party). The Occupy protesters have very high supermajority requirements at their general assemblies, but they do not have this clash, this diversity in either viewpoints or demographics. They have procedural near-unanimity but not actual consensus governance, leading to a system that excludes most interest groups that comprise the 99%; unsurprisingly, the movement has severe problems with race, since its center is white and thinks it speaks for everyone.

Of course, within the union movement something similar is happening, with the dominant group being the older members. This is what New York-area transit commenter Larry Littlefield calls Generation Greed, spanning people of all political classes.

The end result is that no matter how much rhetoric is thrown around about new politics, forward-looking progressives, and so on, what ends up is a repetition of an old hierarchy, one with Real Working People and with fake ones. It has to; when it has no capability of dealing with tensions between transit users and other groups, or between whites and blacks, or between labor and small business, it cannot project any unity of the 99% otherwise. And without unity, it’s a movement without any clear policy agenda.

Commuter Rail, Urban Infill Stations, and Shuttle Train Rapid Transit

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.

Destination Centralization

It’s by now a commonplace that jobs are more centralized than residences, in terms of CBD concentration. But what I think is worse-known is that destinations in general are incredibly centralized, both across and within metro areas. In other words, people from out of town, especially out of country, are more likely to visit the more central metro regions, and within those regions are more likely to visit city center.

For good examples, take tourist travel to Britain and France, both conveniently capital-centric for this discussion. London has 15.6 million annual international visitors, slightly more than its metro area population; Paris has 9.7 million, slightly less than its metro area population. Most secondary cities in both Britain and France don’t even come close: the same ratio in Glasgow, Leeds, Manchester, Liverpool, and Birmingham ranges from one quarter to one half, and in secondary French cities is even lower, down to one ninth for Marseille. (Nice and Monaco, a specialized tourist region, punch above their weight; so does Edinburgh.) You can peruse the numbers and see that the same observation is true in a number of countries with one well-known global city, excepting those with a different region specializing in tourism.

For business travel specifically, one look at the distribution of four- and five-star hotels in a country and a metro region will show similar centralization. For example, consider the New York hotels shown on Five Star Alliance. Counting separately listed hotels in Connecticut, there are 56 five-star hotels, of which 50 are in Manhattan (mostly in Midtown), four in Fairfield County, and one each in Hoboken and Huntington. On hotels.com, there are 40 four-and-a-half- and five-star hotels; of those I can find information about 37, and of those 36 are in Manhattan and one is in White Plains. In Boston, Five Star Alliance shows 18 hotels, one in Cambridge and the rest in Back Bay and Downtown Boston; hotels.com shows 11, all downtown or in Back Bay. In Philadelphia, Five Star Alliance shows 8 and hotels.com 4 of which I can find information about 3, and in both cases all hotels are in Center City.

Let’s untangle what this means. Of course there’s a concentration of activity in Manhattan, Downtown Boston, and Center City. Just not that much. Manhattan has 22% of the jobs in Greater New York; it doesn’t have 50 in 56 jobs, or even 50 in 56 jobs that require commuting (it has 36% of jobs that involve out-of-county commuting).

I believe this boils down to a specialization of usages that attract visitors from far away. There is tourism in the Hamptons and the Jersey Shore, in the Poconos and the Hudson Highlands, in Vermont and Cape Cod. However, a huge fraction of it is local. I doubt anyone from California has ever visited the Northeast for the primary purpose of skiing in Vermont, unless it involved a corporate retreat with a lot of locals. The things that are special enough to attract people from far away are by definition uncommon. Moreover, unless those are obscure niches, they will be famous enough to have the resources to pay for prime location. They’ll cluster in the CBDs of the largest cities because everything else relevant to them is in the CBDs of the largest cities; the main factor that can break agglomeration economics, high cost, is less relevant to them.

It’s the same reason why CBDs so often host corporate headquarters, major law firms, and similar outfits. Once the cluster has been established, everyone wants to be in it, and as a result of competition, only the richest users, typically the ones with the most global networks (thus, most likely to bring in outside travelers), can afford it.

What this means for an intercity transportation network is that being located downtown has great value, even in very suburbanized metro areas. A station in the San Francisco CBD is more valuable than one in San Jose or Gilroy, and a station in Downtown Los Angeles is more valuable than one in the San Fernando Valley or Palmdale. The same is of course true of the intermediate cities, and this is why there’s a good reason to serve their downtowns rather than skirt them as the LGVs do. (Of course, there are other reasons – cost and noise – to not serve their downtowns. However, ignoring costs, the benefits are on the side of downtown stations, making a value engineering decision to avoid urban areas less obvious.)

This is one primary advantage of high-speed rail over flying: it gets you closer to your destination. To leverage that, operators make sure to locate their stations as close as practically possible to the CBD. In no place that I am aware of did HSR serve a city at a peripheral location, except when necessary for line geometry. Japan National Railways built Shin-Osaka because it was impossible for a through-line to get to Osaka Station above ground, and SNCF builds peripheral stations for small towns to avoid expensive urban construction; in neither case do trains pass by a CBD but stop elsewhere, and in both countries HSR builders make major effort when reasonably practical to serve city centers.

Bus and Rail Mantras

Bus is cheaper than rail. Paint is cheap. Rail only made sense a hundred years ago when construction costs were lower. Trains have no inherent advantage over buses. It doesn’t cost more to operate a bus than to operate a train. All of those are true in specific sets of circumstances, and Curitiba and Bogota deserve a lot of credit for recognizing that in their case they were true and opting for a good BRT system. Unfortunately, the notion that buses are always cheaper than trains has turned into a mantra that’s applied even far from the original circumstance of BRT.

The advantage of buses is that dedicating lanes to them and installing signal priority are financially cheap, if politically difficult in the face of opposition from drivers. Even physically separating those lanes is essentially cost-free. This advantage disappears completely when it comes to installing new lanes, or paving an existing right-of-way. Hartford is paving over an abandoned railroad at a cost of $37 million per km.

Not to be outdone, New York’s own MTA just proposed to pave about 8.5 km of the Staten Island Railway’s North Shore Branch for $371 million. A light rail alternative was jettisoned because the MTA insisted on continuing the line to the West Shore Plaza, along what is possibly the least developed road in the city.

Another, related mantra is that light rail is cheaper than heavy rail. This contributed to the MTA’s decision not to pursue a Staten Island Railway-compatible solution, which would allow lower capital costs and cheaper maintenance since trains could be maintained together with the existing fleet without modifying the existing yard. As with all mantras, this one has a kernel of truth: it’s much cheaper to build on-street light rail than elevated rail or a subway. As with the BRT mantra, this is not true when the discussion is about what to do in an existing right-of-way.

Worse, because the MTA believed its own hype, it completely missed the point of surface transit. People who believe these mantras about bus, light rail, and heavy rail can easily miss the advantage of on-street running wherever the streets are more central than the railroad rights-of-way. The North Shore Branch hugs the shore for much of the way, halving station radius. The most developed corridor is Forest Avenue, hosting the S48, the third busiest bus in the borough and the busiest in the same area and orientation as the line in question. (The busiest in the borough, the S53, crosses the bridge to connect the North Shore to the subway in Brooklyn.) Of the three other east-west routes in the North Shore, the one that the North Shore Branch parallels the most closely, the S40, has the lowest ridership. It would be both vastly cheaper and better for bus riders to have dedicated bus lanes on Forest, or possibly Castleton, which hosts the S46.

In cities that did not develop around mainline rail corridors but rather around major streets, the only reason to use mainline rail corridors for urban transit is that reactivating them for rail can be done at much lower cost than building on-street light rail. New York is for historical reasons such a city: Staten Island development follows Forest and Castleton rather than the North Shore Branch, and for similar reasons Park Avenue in Manhattan and the Bronx is a relatively unimportant commercial corridor.

Now, these mainline corridors have great use for regional transit. Queens Boulevard can’t be easily used for train service to Long Island, and Lexington Avenue can’t be easily used for train service to Westchester. Staten Island has great potential for regional transit – but only if it’s electrified rail going through a tunnel to Manhattan. It’s expensive, but it’s what it takes to be time-competitive with the ferry and with buses to the subway. A more competent agency than the MTA would keep planning and designing such high-cost, high-benefit projects, to be built in the future if funding materializes; such plans could also be used to concretely argue for more funding from the state and from Congress.

Instead, the MTA is spending more money than most light rail lines cost, to make such a mainline connection from the North Shore to Manhattan impossible in the future. The best scenario in such a situation is that the busway would have to be railstituted, for a few hundred million dollars – an embarrassing reminder of the busway folly, but still a much smaller sum than the cost of the tunnel. The worst scenario is that like on Los Angeles’s Orange Line, the need to keep buses operating during construction would make it impossible to replace them with trains.

There aren’t a lot of lose-lose (or win-win) situations with transportation, even if we ignore driver convenience, but this is one of them. It’s a fiscal disaster relative to predicted ridership and the operating costs of buses, it makes future transit expansion in the borough more difficult, and it follows a marginal route. All this is so that the MTA can say it’s finally making use of an abandoned right-of-way.

High- and Low-Speed Rail Coordination

The debate about what kind intercity rail to build tends to be either/or. On one side, there’s HSR-only advocacy: this represents the attitude of SNCF, especially in the earlier years of the TGV, and such American HSR proponents as John Mica. In this view, legacy rail is inherently slow and money-losing and the best that can be done is to start fresh; generally, this view also looks down on integration with legacy regional rail. On the other side, there’s a legacy-only advocacy, which represents how Britain upgraded its intercity rail network in and after the 1970s and also the attitude of proponents of Amtrak-plus lines in the US.

The problem with this is that there are a lot of different markets out there, and the service levels they justify and the construction challenges they impose are different. Sometimes such markets are in the same general area, and this means some lines should be HSR and some should be upgraded low-speed rail.

Countries that tried to go to one extreme of this debate are now learning the hard way that they need to do both. Britain radically optimized its intercity main lines, which now have the highest average speed in the world except for HSR – but it needs more, and this requires it to build a new HSR line at immense cost. In the other direction, France’s TGV-only strategy is slowly changing. SNCF still doesn’t care about legacy intercity lines, but the regions are investing in regional rail, and one region even uses the high-speed line for local service. Japan gets away with neglecting most of the intercity lines because its physical and political geography is such that markets that can support HSR dominate, but other countries cannot.

This means that best network design is going to have to deal with both approaches’ political difficulties at the same time. Upgrading legacy rail means upgrading legacy rail operating practices, against opposition of workers and managers who are used to old and inefficient ways of doing things. And building HSR on the thickest markets means giving special treatment to some regions with infrastructure that other regions don’t justify; it’s economically solid, but the optics of this are poor.

But the advantage of doing it this way from the start is that it’s more future-proof, and allows integrated design in terms of schedules, which lines are upgraded, how cities are connected, and so on.

Doing it piecemeal may require redoing a connection along a different alignment. The issue is that HSR compresses travel times along the line only. It’s like urban rapid transit this way, or for that matter like the air network. A legacy rail system (or a national highway system, or urban buses) has fairly consistent average speed. This means that in a combined system, the optimal path between two cities may not be the shortest path, in case one is close to the HSR trunks.

For example, look at Upstate New York. None of its four major metro areas is large enough to justify a high-speed connection to New York by itself, but all four combined do. Although international service to Toronto is overrated, it could be justifiable in light of Buffalo’s relative economic integration with Ontario and also the mostly straight, partially grade-separated right-of-way available in Canada; this would further thicken the market.

If we draw a rudimentary map of other desired connections, none thick enough to warrant more than an upgraded low-speed train, the fastest connections are not always obvious. For example, with average HSR speed of 240 km/h and legacy rail speed of 100 km/h, it’s faster to get from New York to Ithaca via Syracuse than directly via Binghamton. This is why the connection to Ithaca is through a line that points toward Syracuse, even if it’s not the shortest route to Binghamton. It’s one of many small local optimization problems.

More interestingly, we get a mini-hub in Syracuse. Although it’s the smallest of the four main Upstate cities, it lies at the junction of the trunk line and lines to Binghamton and Watertown, and also has secondary cities at the right location for regional rail. (The largest comparable secondary city near Rochester is Geneva, which happens to be close to and have a good rail connection to I-90, a prime candidate for HSR corridor; thus it should get commuter service using the trunk line, which would be far faster than an all-legacy train.) This means that schedules should be set up to coordinate transfers in Syracuse.

This is a normal way to set things up in an all-legacy format, as is done in Switzerland, but it can equally apply to HSR. The construction challenges on the Empire Corridor are nowhere near as complex as those in California, Pennsylvania, and other truly mountainous states, but they’re still nontrivial. But now that we know that Syracuse should be a hub, one answer to the question “How many design compromises to make to reduce costs?” is “Build just enough to allow integrated transfers in both New York and Syracuse.”

(In practice this means HSR arriving in Syracuse on the hour and in New York whenever convenient. The main intercity line into New York is the Northeast Corridor, a very thick market that at HSR speed would have enough traffic to support show-up-and-go frequency. This is not true of lines serving Syracuse; Watertown is not Washington and Binghamton is not Boston.)

The main cost of doing things this way is political. It requires willingness to both prioritize markets and cut construction costs, as necessary to build HSR, and improve legacy rail operating practices and carefully integrate services, as necessary to build a working legacy rail network. The fiscal cost is not outrageous – those legacy lines are cheap relative to everything else (rebuilding the unelectrified New York-Scranton line is $550 million), and HSR on thicker markets will at least partially pay for itself.

Once we discard the notion that present-day Amtrak operating patterns are adequate, the question stops being about whether one trusts Amtrak or not, and purely about how to build a new transportation network. And then the correct answer to “High-speed or legacy?” is “Both, seamlessly integrated with each other.”

The Cost of Heavy Freight Trains

Over at Pennsylvania HSR, Samuel Walker reminds us that the dominance of coal for US freight traffic slows down passenger trains, and this has a social cost in addition to the direct costs of coal mining and burning. But another post of his, regarding cant deficiency, suggests more problems coming from mixing modern passenger trains with very heavy freight. Coal trains slow all other traffic in three different ways, of which just one is the conventional schedule conflict, and even that means more than just slowing down intercity trains.

Schedule conflict reduces not just speed, but also span and punctuality. The Northstar Line in Minnesota shares track with BNSF’s Northern Transcon; since the line is freight-primary, there’s no room for off-peak service, and passenger trains can’t extend to the line’s natural terminus in St. Cloud, not without constructing additional tracks. Similarly, in Houston, plans for a commuter line to Galveston included peak-only service from the start.

Second, independently of scheduling, slow trains force faster trains to slow down by limiting the amount of superelevation that can be used. As a reminder: on curves, they bank the track, with the outer rail above the inner rail, to partly counter centrifugal force. If they do not cant the train enough, there’s cant deficiency; if they cant too much, there’s cant excess. Although there are strict limits for cant excess (in Sweden, 100 mm, or 70 on tighter curves), stricter than for cant deficiency (150 mm for a non-tilting passenger train, give or take), technically commuter trains could safely run at higher cant excess; however, for freight trains, high cant excess is unsafe because loads could shift, and the higher axle load means trains would chew up the inner track. Very heavy trains first require the track to have a lower minimum speed, and second have an even more limited cant excess because of the damage they’d cause to the track (about 2″, or 50 mm, in US practice). Walker links to a US standard guideline that uniformly assumes 3″ cant; greenfield high-speed lines go up to 180-200 mm.

And third, heavy freight trains damage tracks regardless. Coal trains also limit the amount of revenue the railroad gets out of each train, leaving limited money for maintenance, and are not time-sensitive, giving railroads no reason to perform adequate maintenance. To compensate, industry practices have to be less than perfect: cant and cant deficiency are less than the maximum permitted by right-of-way geometry and minimum speed, and freight railroads require barriers between their track and passenger track to protect from inevitable freight derailments. Even then the US safety level is well below what’s achieved anywhere else in the world with trustworthy statistics.

Of course, coal provides a great boon to the freight railroads. It’s a captive market. The railroads could price out coal and focus on higher-value intermodal traffic. Some of the lines that already focus on intermodal traffic are friendlier to passenger service, such as the FEC.

However, realistically, the end of coal is only going to come from environmental regulations. Those same regulations would apply to oil, inducing a mode shift from trucks to rail. The coal trains that would stop running would be replaced by trains carrying higher-value goods. The details depend on what the purpose and kind of environmental regulations are, but today’s environmental movement is heavily focused on climate change and not as concerned with local environmental justice, so loss of coal traffic due to a high carbon tax or local air pollution tax, both of which would also affect oil and gas, is much likelier than loss of coal traffic due to restrictions on mountaintop removal and air quality regulations at mining sites, which would not. (Of course oil causes plenty of damage to the biosphere, but the mainstream environmental movement is much more concerned with effects on humans than on other organisms.)

The political issue at hand, besides the easy to explain but hard to implement matter of avoiding catastrophic climate change, is what freight railroads are used to. Their entire business model is geared toward relatively low-value goods. A steep carbon tax is a risk: it should raise their mode share of total value of goods transported, which is currently 4% (see also figure 4.3 here), but it would come from a new set of goods, with requirements and challenges different from those of the current mix. The railroads would have to reintroduce fast freight, which most haven’t run in decades, and refine it to deal with the needs of shippers today. It’s not only a headache for the managers, but also a substantial risk of failure – perhaps rival railroads would be able to get all the traffic because they’d adapt to the new market faster, perhaps shippers would change their factory placement to move goods over shorter distances, perhaps they would not be able to cope with the immediate increase in fuel costs, etc.

Because of this, freight railroads may end up fighting a policy that would most likely benefit them. Although they represent a critical part of an emission reduction strategy, and are all too happy to point out that they consume much less fuel than trucks, fuel is a major cost to them, and coal is big business for them. These are not tech startups; these are conservative businesses that go back to the 19th century. Heavy coal trains then add a political cost as well: they help turn an industry that could be a major supporter of climate change legislation neutral or hostile to the idea.

Where Should Streetcar Corridors Be?

At a meeting of some of the Greater City people about the Providence streetcar proposal, many of us had severe criticism of the current plan. The line is too short; it is S-shaped; it detours to serve a hospital that’s close to but not on a straighter route; the frequency is mediocre; RIPTA does not have a clear plan of where subsequent lines would go. The discussion quickly turned to alternatives, involving frequent-stop commuter lines to the inner suburbs on existing trackage and perhaps a new connection to the rail tunnel, and streetcars along major corridors to fill in the gaps. It is the streetcar corridors that I want to discuss.

In brief, the existing streetcar proposal only links downtown with near-downtown job centers in College Hill and at the Rhode Island hospitals; secondary centers and neighborhoods would be served in the future, along undetermined routes. People at the meeting who know more than me believe that the western leg, serving Olneyville, is likely to be on Broadway by default, as it is a wide street, and likewise a future westward expansion would follow Manton, a similarly wide street. Instead, they propose, the streetcar should follow Westminster Street.

The issue at hand is, partially, development. Broadway looks a little more developed than Westminster (excluding the portion within downtown proper, where Westminster is a major commercial street), but this development is not dense. Westminster has developed parts and undeveloped parts that could be used for TOD. This is more than just development-oriented transit – Westminster is on the way to Olneyville – but it’s a partial reason.

But the main issue is location. The proposals that we developed at the meeting hinge on using major streets that are centrally located within neighborhoods. We prefer Hope Street to Main Street on the East Side, even though Main Street supports a higher frequency on the 99 bus than Hope Street does on the 42, because Hope Street is accessible from the entire East Side. (Both have auto-oriented commercial development that could potentially be densified.) Likewise, Westminster is closer to parts of the West End; the idea is to run down Westminster and Broad in that direction to serve the western and southern parts of the city.

This is not how I’m used to thinking about where to put favored routes, whether they are light rail or BRT. Usually I think in terms of how developed the immediate area around the street is, what destinations there are, and so on – in other words, spiky density near the route rather than general density within half a kilometer in each direction. That said, this thinking is informed by rapid transit, which is at much larger scale, and bus-oriented density is more diffuse.

The question is whether the rough sketch that came out of the meeting makes sense, or whether it’s just lines on a map. At several places, there’s tension between serving the immediate street and serving a broader neighborhood. At others, some routes are good for only part of the way: for example, in Pawtucket the streets feeding into Main are actually more central and more densely populated than that feeding into Hope, a reversal of the situation in Providence. For another example, Atwells is highly developed but not centrally located in Federal Hill, and is the opposite in Olneyville.

I’m interested to hear what existing successful practices are. Do good streetcar (or rapid bus, etc.) corridors just follow the most successful bus lines and the most developed individual streets, or do they instead serve a broader swath along the routes?

Quick Note: How Much Tunnels Really Cost

New York is currently building a 3-kilometer tunnel between Brooklyn and Staten Island, using the same EPB method that Madrid uses to build subway tunnels. The cost of the single-bore tunnel is $250 million, and the project will be completed by 2014.

Of course, this is a water tunnel rather than a train tunnel. The diameter of the tunnel is somewhat smaller than that of a single-track train tunnel. Double-track tunnels, even ones built to high-speed rail standards, are substantially wider, but the amount of concrete lining required is proportional to radius rather than to cross-sectional area. For example, the double-track Seikan Tunnel is 9.7 meters wide, little more than single-track HSR tunnels in Europe, as Japanese construction tries to minimize tunnel clearances to cut costs and instead equip Shinkansen trains with elaborate aerodynamic noses. While 9.7 is more than 2.5 times the diameter of the water tunnel in question, 250 million times 2.5 is still far below the construction cost of any recent tunneling project in New York.

The expensive part of tunneling, then, is not the actual tunnel. It’s everything else, especially the station caverns. Both ARC and East Side Access included multilevel deep caverns in Manhattan with full-length mezzanines; of course they’d be more expensive.

For what it’s worth, an 8-kilometer long, 9.7-meter wide tunnel from Staten Island to Manhattan would cost $1.75 billion at the same per-km, per-meter cost of this water tunnel. Of course stations at St. George and especially Lower Manhattan would add much more, forcing a lot of difficult choices about location, but the basic infrastructure is not all that expensive.
