Authoritarian Leaders and Agenda Setting
On Tuesday, Andrew Cuomo proposed a new signature initiative: a $450 million AirTrain to LaGuardia, connecting to the Mets’ stadium on both the 7 train and the LIRR. The proposal has practically no merit even as an airport connector: Ben Kabak and Yonah Freemark both note, with helpful graphics, that the connection is so circuitous it’d be slower than the existing bus-subway options to nearly every destination, including everywhere in Manhattan. Capital New York notes that in general, transit activist reactions to the plan were cold, precisely because it’s such bad transit.
The interesting aspect of this is about the counter-criticism, and the discussion it led to. (In contrast, Cuomo’s general hostility to transit and intercity rail is not news, and it’s unlikely someone with such a history could come up with cost-effective transit plans.) The main reaction to the criticism is not “where would you spend $450 million instead?”. That question has a few answers, all of which are boring: the general MTA capital plan, or, if the money is to go to expansion, Second Avenue Subway Phase 2, the next item on the city’s transit agenda now that Phase 1 is nearing completion.
Instead, the main reaction is “how would you connect to LaGuardia instead?”. That question, too, has a definite answer, which Ben talked about in his post, and which I pointed out in my post about airport connectors last year: an extension of the N to the east, with several stops (for example, at Steinway and Hazen) to serve more of Astoria and not just airport riders. The N takes a direct route to Manhattan, passing through or next to the top areas for LaGuardia passengers, as seen in the second map here. But even that is the wrong question. There are probably more cost-effective subway extensions in New York, having nothing to do with LaGuardia; I have to say probably, since at no point has the MTA proposed large enough a slate of possible extensions that we can compare projected costs per rider and say “this is the best.” There might even be better ways to extend the N eastward than to LaGuardia: an elevated line over Ditmars, a short segment of the Grand Central Parkway, and Astoria Boulevard would serve East Elmhurst, a dense, transit-deprived section of Queens, and would probably produce higher ridership than a swerve from the GCP to the airport.
Such is the power of a governor who’s accountable to nobody: he proposes a scheme, and even the criticism is on the governor’s own terms of providing service to LaGuardia. Yonah compares travel times to various destinations on various alignments for connecting LaGuardia to the subway. Nate Silver’s response has an infographic with travel times from the airport to city hall in various American cities – an infographic that is of little use to New York, where the main destination is far north of city hall, but is well within the general topic of LaGuardia’s airport connections. Even I, cognizant of this agenda-setting power, have to at least mention an alternative LaGuardia connector, knowing readers will want a plan.
The cheeky response to this is that in a democracy, this wouldn’t happen. Now, the US is a democracy. Cuomo has to stand for election every four years. The worst infrastructure disasters tend to be in countries that are authoritarian through and through: Russia’s elevated winter Olympics costs in Sochi and Qatar’s human rights abuses in the World Cup preparations are the two biggest recent examples. But democracies with insufficient checks on political power are susceptible to this as well. This is common in the third world, where corruption is more common – hence the abuses of the World Cup last summer, in a solidly democratic country – but can also happen in developed countries with democratic deficits.
Usually, the phrase democratic deficit refers to the EU, and by analogy other supranational organizations. But in the US, it’s a useful framework for thinking of local and state governments. Rick Scott, Scott Walker, and John Kasich needed nobody’s approval to reject federal funding for intercity rail. Chris Christie did not need anyone’s approval to cancel ARC, or to cause traffic jams in retribution against a mayor who refused to endorse him; in a recent article in New York YIMBY, defending the cancellation of ARC as originally proposed, I made sure to take multiple barbs at Christie, just to avoid playing into the agenda of canceling ARC to posture about government waste while diverting rail money to the New Jersey Turnpike.
Cuomo’s power is if anything even greater: the New York state government works by a three men in a room model, in which the governor, the speaker of the State Assembly (just indicted for corruption), and the majority leader in the State Senate (currently relatively powerless and dependent on Cuomo) wield all practical power. In such a system, Cuomo does not have the power to shoot protesters, thankfully, but does have the power to propose megaprojects that glorify him, without a broad discussion with stakeholders, in which the MTA’s long-term expansion plans and cost-benefit ratios would come into play.
Last year, in writing about elite infrastructure projects that are not about meeting a service need, I noted that talking about such projects in terms of cost-effectiveness is moot, because they were never intended to be about benefiting the wider public. We could discuss where to spend money on transit in New York in the way that would benefit the largest number of riders. We could even discuss what the optimal way of connecting to LaGuardia is, before comparing the best connection with non-airport projects to see where it should lie on the list of future expansions. But it would be pointless, because Cuomo is not interested in spending money on benefiting the largest number of riders; he frankly does not care about transit riders. When the time came to support transit riders, for example in signing a lockbox bill guaranteeing that money the state government had promised the MTA would indeed go to the MTA, he vetoed the bill instead.
In such a climate, as soon as we talk about tweaks to Cuomo’s plan, Cuomo’s already won; whatever happens, he will reap the credit, and use it to buy political capital to keep building unnecessary megaprojects. Even trying to make the best of a bad situation by making the airport connector better is of little use, since Cuomo will support the plan that maximizes his political capital and not the one that maximizes transit usage even within such constraints as “must serve LaGuardia.”
This is evident in his response to criticism among transit activists. After listing the many pundits and activists who oppose the plan, Capital New York included a response from the governor’s office, which said, in so many words, “our plan is better because it doesn’t go through populated neighborhoods, where there would be NIMBYs.” What those of us who want good transit view as a feature – connecting to underserved neighborhoods and not just to the airport – Cuomo regards as a bug. A plan that included additional stops in Astoria might well attract community support, while still offering much faster trip times to Manhattan because of the direct route, but would rely on non-airport ridership, which Cuomo doesn’t care about, to keep the cost per rider reasonable.
Because of this disconnect between what would work for transit users and what would work for Cuomo, the only reasonable answer to the plan is a simple no, which should be said as sharply as possible. No working with the proposal: it’s terrible, a true stone soup. No tweaks: Cuomo wouldn’t want any ingredients that would improve the soup, and would insist on keeping the stone in anyway. (He doesn’t have to eat it, he doesn’t use transit either way.) And, within the parameters of a transit conversation in which people are desperate to see expansions, no discussion that validates Cuomo’s original plan.
Update 7/28: in a joint announcement with Joe Biden, Cuomo has just announced $4 billion in airport improvements at LaGuardia, bundling the rail connector into the larger projects. I have nothing to add that I didn’t already cover in this post and in my older post about elite infrastructure investments.
Who Rides Commuter Rail?
I’ve had an argument in comments with the author of Purple City about who commuter rail should serve. He’s argued before that cities should make sure outer suburbanites can get to the center via express commuter rail, and I will add that American cities do do that, and orient commuter rail too much around the needs of peak-hour outer suburbanites. Insofar as I think cities should have commuter rail there’s no disagreement, but what I think they do wrong is focusing too much on the peak. The two practices in contention are the low off-peak frequency (for example, Metra’s Union Pacific-North Line, which has no freight to speak of, has worse than hourly off-peak service), and the stop distribution, which has trains making few or no stops in the city proper.
The common thread of these two practices is that they optimize one variable: peak travel time for a suburban commuter to the CBD. This neglects other sources of ridership on commuter rail, which are suppressed in the US but significant in countries with more modern operating practices. I will contrast the peak-focused approach with a rapid transit approach, using examples that I believe will show that the latter is bound to get far more ridership, even in the suburbs.
First, let us imagine a contrasting system, one in which North American commuter rail looks more like an RER, an S-Bahn, or a Japanese commuter rail network. Such a system will have the following features:
1. Relatively consistent stopping pattern. The busier lines may have local and express trains, but the express trains will stop at the same major stops. Local trains will make all local stops over a fairly wide stretch.
2. Low ratio of peak to off-peak frequency, in the vicinity of 2:1 or even less. In a major city like Chicago or New York, a line that can’t support half-hourly service all day, at a bare minimum, will likely have no service at all; the only exceptions I can think of are services at range so long they’re practically intercity, like New York-Hamptons or New York-Allentown.
3. An urban stopping pattern that’s not too express. If there’s a parallel subway then it’s okay to have a somewhat wider stop spacing than in the inner suburbs beyond the subway’s range, but still closer to the 2-3 km range than the 4-5 km range of Metra.
If it’s possible to do so technologically, then the commuter line may be interlined with a subway line, even. This is usually hypothetical, since subways and commuter trains, where both exist, are almost always technologically incompatible; Tokyo and Seoul are the two major exceptions, with London a borderline case. However, it’s useful to consider such hypothetical cases, to examine what would happen to train service. I will consider two such cases: having Vancouver’s Evergreen Line take over West Coast Express (the original argument), and having Boston’s Red Line take over Old Colony Lines. Neither situation is technologically possible, even ignoring FRA and Transport Canada regulations, as both Boston and Vancouver build subway tunnels for much smaller trains than run on the mainline, but this discussion may be useful in cases where a takeover is feasible, such as when the commuter line is an isolated branch. I prefer to discuss the hypotheticals since the two examples in question are purer examples of priorities: outer-suburban peak service, or rapid transit-style service.
Vancouver
Vancouver’s rail service consists of the SkyTrain network, which gets about 400,000 weekday riders, and the West Coast Express, a peak-only commuter rail network running 5 trains per day per direction, with 11,000 weekday riders. SkyTrain’s under-construction Evergreen Line will intersect the West Coast Express at Port Moody and Coquitlam, and then serve more stations in Coquitlam off the mainline, while the WCE continues much farther to the east, into the Vancouver exurbs. The WCE connects Port Moody to Waterfront in 25 minutes and Coquitlam in 30 minutes; the Evergreen Line is projected to take 33 and 38 minutes respectively, with a transfer at Broadway/Commercial. Despite the slower service, the much higher frequency, all-day service, and connections to more of the Vancouver metro area win: the projected ridership for the Evergreen Line is about 23 million a year (see Table 2 on PDF-p. 4 here), which corresponds to about 75,000 per weekday.
Now, what’s in contention is whether it would be wise to have the same treatment at WCE stations farther east. The potential ridership at those stations is lower since they’re in less built-up areas, so it is likely cost-ineffective to build an Evergreen Line branch along the Canadian Pacific mainline and have it replace the WCE, but if such a line were built, it would most likely have the same effect on travel times: people would have to transfer at Broadway/Commercial, and not including the transfer time take 8 minutes more to get to Waterfront. The eastern end of the line, Mission, has 75-minute service now, and this would change to 83-minute service plus a transfer.
I claim that Mission residents would still take the train more often if it were 8 minutes lower. The reason is simple: as a proportion of overall travel time, the 8 minutes are more important to a 25-minute Port Moody commuter than to a 75-minute Mission commuter. Mission commuters live farther out, so they’re somewhat less likely to care about service to various neighborhoods along the way, but they’re even less likely to care about 8 minutes. They also are less likely to care about very high frequency, since their trips are longer, but they do care about service availability all day, even if they’d be okay with half-hourly service. Moreover, the Evergreen Line will connect to secondary nodes like Metrotown better than the WCE does, and eventually have direct service to Central Broadway and UBC, both of which draw commuters from the entire region.
In the present, the WCE works as a placeholder – it’s possible to reduce staffing and improve turnaround times to allow off-peak service, but there’s too little population east of Coquitlam to justify a SkyTrain extension, and so far population growth is fastest in inner-suburban Port Moody and Surrey (see here and here) and not east of Coquitlam. In the future, if those areas grow then it will make sense to replace the WCE with SkyTrain. WCE upgrades are unlikely – adding infill stations is practically impossible, as the line hugs an active port, with no good station sites. While SkyTrain’s driverless configuration keeps operating expenses down, it makes it impossible to extend branches to the suburbs cheaply by running them at-grade and in mixed traffic with freight.
Boston
Several of Boston’s subway branches are parallel to extant or closed commuter lines. The Orange Line runs alongside the Northeast Corridor to Forest Hills, the Blue Line took over parts of the narrow-gauge Boston, Revere Beach and Lynn Railroad, the Green Line D Branch took over a commuter rail loop used by the Boston and Albany, and the Red Line took over a New Haven Railroad branch line to Ashmont and runs alongside the Old Colony Lines to Braintree. At the time the Braintree extension opened the Old Colony Lines were closed for passenger service, but they have been since reopened, running from Braintree to South Station with just one stop in between, either JFK-UMass or Quincy Center (never both, except on trains that skip Braintree); off-peak frequency is about every two hours on each of two lines, and with some off-peak trains skipping Braintree, service to Braintree is worse than hourly. The Red Line takes 26-27 minutes to go from Braintree to South Station, the Old Colony Lines take 19-21 minutes.
As is projected in Vancouver, ridership on the Red Line is much higher: according to the 2014 Blue Book, on PDF-pp. 14 and 74, the busiest MBTA commuter rail station, Providence, gets 2,325 riders per weekday and the busiest Old Colony station, Bridgewater, gets only 1,036, while the Braintree extension’s five stops get 6,975, 4,624, 8,655 (Quincy Center), 4,785, and 5,122 (Braintree). Those five stops get 30,000 riders between them, meaning 60,000 since it’s unlikely people ride internally on the extension; this is nearly half the entire MBTA commuter rail ridership, and three times the ridership on the Old Colony Lines (counting Greenbush, which diverges at Quincy, as a third line).
As in Vancouver, I claim that a Red Line extension taking over the Old Colony Lines would have much higher ridership. Of course the frequency per line, already middling since the Braintree extension is a branch, would not be very good; but at the range of the suburbs served by these lines, half the current frequency of the Red Line, giving about 20 minutes at the peak and 30 off-peak, is enough, and is a massive improvement over multi-hour headways. The extra 5-8 minutes of travel times matter less as one moves farther out, again; travel time to South Station from the first Old Colony stations past Braintree, South Weymouth and Holbrook/Randolph, is 28 minutes, about the same as from Braintree on the Red Line, and those two stations have a bit more than 500 weekday riders each.
Moreover, the Red Line has something the commuter trains don’t: service to multiple centers within the inner Boston region. Downtown Crossing is closer to most jobs than South Station, saving people the walk. Cambridge is a major job center in its own right (it has more jobs than any New England city except Boston, ahead of Providence, Worcester, and Hartford). Back Bay is a bit more accessible via the Orange Line at Downtown Crossing or the Green Line at Park Street than via commuter rail at South Station.
Like SkyTrain, the Red Line can’t run on mainline rail tracks, and there is not enough population to justify an extension, nor enough population growth in New England for such an extension to ever pencil out. However, it’s possible to modernize commuter rail, as I have written before. This would not provide direct service to Downtown Crossing or Cambridge, but could provide cross-platform transfers to Back Bay, decent frequency all day, and, since regional EMUs can have very good performance characteristics, much higher average speeds than with today’s slow diesel locomotives even if trains make more stops.
General Remarks
The examples of Boston and Vancouver’s ridership patterns suggest that it’s okay to sacrifice speed to provide coherent service. It’s worth noting here that the bulk of present-day ridership on North American commuter rail would not benefit too much from such sacrifice. North American commuter rail provides awful service in the off-peak or to non-CBD destinations: even the Newark CBD, relatively well-served by New Jersey Transit, has a 26% mode share as a job center as of 2000, as per an Alan Voorhees Transportation Center report called Informed Intuition (PDF-p. 13). There’s a huge amount of latent ridership on North American commuter rail, which is why rapid transit gets so much more ridership than peak-focused commuter rail.
This doesn’t change much at different ranges of distance from the center. The few minutes saved by expressing through the city to the CBD matter a great deal to the suburbs right beyond city limits, but those innermost suburbs are precisely the ones that could make the most use of service to multiple city nodes. Farther out, where commuters to the city tend to be more likely to be working at the CBD, since it is more specialized than most secondary nodes, frequency and service to everywhere matter less, but the extra few minutes matter even less.
However, since present-day riders are precisely the narrow slice of potential users who are okay with the current setup, they have the potential to engage in NIMBY protests against any attempt at modernization. Why change what works for them? This is why Long Island representatives oppose such modernization attempts as letting Metro-North access Penn Station; it’s entirely a turf war. Even reforms that do not degrade trip times to the CBD are unlikely in this political situation, for example mode-neutral fares: the people paying premium fare to ride the LIRR or (to some extent) Metra are the ones who are okay with paying this fare, and who may object to increased train crowding coming from lower fares.
Judging by the ridership multiple between the Evergreen Line and WCE, there are likely to be a few million weekday rides coming out of Eastern Queens and Long Island if the LIRR is modernized, but those are not the Manhattan-bound commuters who dominate the discussion today. Instead, they are people who have gotten used to unusable commuter rail, and drive to work, or take long bus-subway commutes to avoid paying higher fares. They do not seem like a significant source of regional rail ridership because they are not current riders (or they ride local transit instead), but they are precisely what makes the difference between the low ridership of every North American commuter rail system and the higher ridership of many European systems.
Mixing Circumferential and Radial Transit
Nearly all rapid transit lines belong to one of two categories: radial lines (a large majority), which connect city center with outlying neighborhoods or suburbs; and circumferential lines (a minority), which go around city center and often serve secondary centers and usually intersect all or nearly all radial lines perpendicularly, such as Paris’s Lines 2 and 6, Moscow’s Circle Line, Seoul’s Line 2, New York’s G train, and Shanghai’s Line 4. In this post, I’m going to discuss an uncommon third category, that of lines that combine circumferential and radial functions: they go toward city center, like a radial line, but then change direction and become circumferential. The G train in New York was like this until 2001, and Line 3 in Shanghai is like this today. This is apropos a proposal by a team Penn Design graduate students to build a variant of Triboro RX in New York that combines Triboro’s circumferential orientation with a radial commuter line. I believe such mixed lines are a recipe for low ridership and strained transfer points, and the Penn Design proposal is inferior to the original Triboro proposal.
First, some details about the mixed lines in question. The example most accessible to most readers is the historical G train in New York. When it first opened in the 1930s as part of the IND, it was designed to both connect Brooklyn and Queens without going through Manhattan and provide local service along radial lines, running alongside express trains that would serve Manhattan. Thus the northern half of the G ran under Queens Boulevard as a local, while the E and F trains provided express service and went to Manhattan. From the start, this arrangement was unstable. Demand for service to Manhattan was much greater than to Brooklyn, so people riding the G inbound changed to the E or F at the first express station after the one they boarded. With overcrowded express trains and undercrowded local ones, the Transit Authority was compelled to build a track connection in 1955 to add a Manhattan-bound local service, and to build a second track connection in 2001 to add another Manhattan-bound local train and remove the G from Queens Boulevard entirely.
In Shanghai, Line 3 was built as an (almost) entirely above-ground line, interlined for part of the way with the circular Line 4. The northern half of Line 3 is radial, running parallel to the overcrowded Line 1. However, where Line 1 enters the traditional center and serves People’s Square, Line 3 swerves west to go around it (missing Lujiazui, the new high-rise CBD to the east of People’s Square), interlining with Line 4, and leaving the loop southward to intersect Line 1 again at Shanghai South Railway Station. Its ridership disappoints not only by the standards of Line 1, but also by those of Line 4: 642,000 on 2014/4/30, the system’s busiest day, compared with 1,384,000 on Line 1 and 907,000 on Line 4. Line 6, which likewise combines a radial function at its northern end with a circumferential one at its center, serving Century Avenue but not Lujiazui or People’s Square, has even lower ridership, 376,000, although this is several times the original projection.
There’s a discussion on Human Transit, in which consensus is that the best circumferential lines connect secondary activity nodes that generate trips in their own right. Now, the G train connects Downtown Brooklyn (the largest business district in New York outside Manhattan) with Long Island City (one of the business districts of Queens), but it lacks the other positive feature of circumferential lines: transfers to the radial lines, to allow one-transfer trips from anywhere to those secondary nodes. The G has good transfers only to other IND lines, and at the Queens end, its transfer to the Queens Boulevard trains was cut in 2001 since, for operational reasons, it was cut not to its old junction with the E and F (Queens Plaza) but one station short (Court Square). Other G transfers are very recent and require a considerable amount of walking.
In contrast to the underperforming G, circumferential lines that both connect important activity nodes and have plenty of radial transfers are backbones of their cities’ transit systems. Shanghai’s Line 4 is fairly busy as noted above. Seoul’s Line 2 is according to a forum post the busiest in the system. Paris’s Lines 2 and 6 are only about average in ridership but combined would be the second busiest after Line 1 (and per route-km are third and fourth, only behind Lines 1 and 4, but are only narrowly ahead of many other lines). The juxtaposition of Shanghai’s Lines 3 and 4 in particular suggests that subway lines shouldn’t try to mix radial and circumferential functions.
Let us go back to the impetus for the post, Triboro RX. The proposal is to largely use existing freight rail lines, all of which are lightly used and could be turned over to the subway, to provide a semicircular line connecting nodes of activity in the Bronx, Queens, and Brooklyn. Because of the focus on using an existing right-of-way to reduce costs, the line misses the most important nodes in Brooklyn and Queens, which are served by the G in any case. However, it passes within half a kilometer of the Hub in the Bronx and, via a short greenfield tunnel, connects to Yankee Stadium, the Bronx’s busiest subway station; it also connects to Brooklyn College and 74th Street/Broadway in Queens, both busy stations if not as central as Downtown Brooklyn or Long Island City. Moreover, it provides direct Bronx-Queens service, which in the existing system requires circuitous routes through Manhattan with difficult transfers, and has reasonable transfers to nearly all subway lines. At the end, the lack of service to Downtown Brooklyn ensures it cannot be a very well-patronized line, but as the right-of-way is almost entirely in place, its cost per rider could be quite low.
In contrast, the Penn Design proposal, called Crossboro, severs the connection to the Hub and Yankee Stadium, and replaces it with service along the Northeast Corridor to Coop City, making sparse stops, at the same locations Metro-North plans to for Penn Station Access; this is 4 stops in 10 km in the Bronx, compared with stops spaced roughly every 800 meters in Queens and Brooklyn, as in the original proposal. The trains would be certified for mainline operation, on the model of the London Overground, rather than segregated from mainline traffic.
The problem with the Crossboro idea is essentially the same as that of the G train until 2001. Most riders at the four Bronx stops are interested in getting to Manhattan, and not to the neighborhoods served by Crossboro, so they’d look for transfer opportunities. The only such opportunity in the Bronx is at Hunts Point, to the 6, which unlike the E and F on Queens Boulevard runs local and provides slow service to Manhattan. With the extra transfer, there is no advantage to Bronx riders over continuing to walk or take the bus to the 2, 5, and 6 trains to Manhattan. Moreover, because of the poor transfers within the Bronx, it’s impossible to use the line to connect from Queens to anywhere in the western half of the Bronx, including Yankee Stadium and the Hub: there’s a connection only to the 6, and none to the 2, 4, 5, or B/D, or to Metro-North.
The principle in action here is that, especially when there are no compelling destinations, it’s critical to make sure the line provides connectivity between large regions. This means connecting to all or almost all radial lines in a region well-served by radial subways but poorly served by preexisting circumferential ones. Not including the 1, which no proposal connects to, the Bronx has five subway lines, all providing radial service to Manhattan; it is a feature of Triboro that it connects to all five (though the connection to the 2/5 requires a long walk), ensuring that people from nearly everywhere in the Bronx can use the line to get to its destinations in Queens and Brooklyn with one transfer. To get from anywhere to anywhere would require two transfers, but to get from a random station in the Bronx to one in Queens or Brooklyn often already requires two transfers, usually at busy Manhattan stations that are out of the way for the crosstown traveler.
Mixing radial and circumferential service interferes with this principle, since the radial component has to come at the expense of completing the circle (or semicircle in a geographically-constrained city like New York). Thus, it’s harder to use the line to get to a large enough variety of points of interest to make up for the fact that it misses the city’s most important destinations. Of course, such a line is also wanting as a radial line, since it misses the center. Thus, ridership underperforms, and the line usually fails to achieve its stated purpose.
What is the MTA Reinventing, Anyway?
In the last few years New York’s MTA has gone through multiple cycles in which a new head talks of far-reaching reform, while only small incremental steps are taken. The latest is the MTA Transportation Reinvention Commission, which has just released a report detailing all the way the MTA could move forward. Capital New York has covered it and hosts the report in three parts. Despite the florid rhetoric of reinvention, the proposals contained in the report are small-scale, such as reducing waste heat in the tunnels and at the stations on PDF-pp. 43-44 of the first part. At first glance they seem interesting; they are also very far from the reinvention the MTA both needs and claims to be engaging in.
Construction costs are not addressed in the report. On PDF-p. 53 of the first part, it talks about the far-reaching suburban Grand Paris Express project for providing suburb-to-suburb rapid transit. It says nothing of the fact that this 200-km project is scheduled to cost about 27 billion euros in what appears to be today’s money, which is not much more than $150 million per km, about a tenth as much as New York’s subway construction. (Grand Paris Express is either mostly or fully underground, I am not sure.) The worst problem for transit in the New York area is that its construction costs are an order of magnitude too high, but this is not addressed in the report.
Instead of tackling this question, the report prefers to dwell on how to raise money. As is increasingly common in American cities, it proposes creative funding streams, on the last page of the first part and the first six pages of the second part: congestion pricing, cap-and-trade, parking fees, a development fund, value capture. With the exception of congestion pricing, an externality tax for which it makes sense for revenues to go to mitigation of congestion via alternative transportation, all of these suffer from the same problem: they are opaque and narrowly targeted, which turns them into slush funds for power brokers. It’s the same problem as the use of cap-and-trade in California.
One of the most fundamental inventions of modern government is the broad-based tax, on income or consumption. Premodern governments funded themselves out of tariffs and dedicated taxes on specific activities (as do third-world governments today), and this created a lot of economic distortion, since not all activities were equally taxed, and politically powerful actors could influence the system to not tax them. The transparent broad-based tax, deeded to general revenue through a democratic process, has to be spent efficiently, because there are many government departments that are looking for more money and have to argue why they should get it. Moreover, the tax affects nearly all voters, so that cutting the tax is another option the spending programs must compete with. The dedicated fund does neither. If the broad-based tax is the equivalent of market competition, a system of dedicated funds for various government programs is the equivalent of a cartel that divides the market into zones, with each cartel member enjoying a local monopoly. In this way there’s a difference between the hodgepodge of taxes the MTA levies and wants to levy and Ile-de-France’s dedicated 1.4-2.6% payroll tax: the payroll tax directly affects all Francilien workers and employers, and were it wasted, a right-wing liberal politician could win accolades by proposing to cut it, the way New York Republicans are attacking the smaller payroll tax used to fund the MTA.
The proposals of where to spend the money to be raised so opaquely are problematic as well. There is a set of reforms, based on best practices in Continental Europe and Japan, that every urban transit system in the first world should pursue, including in their original countries, where often only some of those aspects happen. These include proof-of-payment fare collection on buses, commuter trains, and all but the busiest subway systems; all-door boarding on buses; mode-neutral fares with free transfers; signal priority and bus lanes on all major bus routes, with physically separated lanes in the most congested parts; a coherent frequent bus network, and high off-peak frequency on all trains; and through-service on commuter rail lines that can be joined to create a coherent S-Bahn or RER system. As far as I can tell, the report ignores all of these, with the exception of the vague sentence, “outfitting local bus routes with SBS features,” which features are unspecified. Instead, new buzzwords like resiliency and redundancy appear throughout the report. Redundancy in particular is a substitute for reliability: the world’s busiest train lines are generally not redundant: if they have parallel alternatives those are relief lines or slower options, and a shutdown would result in a major disruption. Amtrak, too, looks for redundancy, even as the busiest intercity rail line in the world, the Tokaido Shinkansen, has no redundancy, and is only about to get some in the next few decades as JR Central builds the Chuo Shinkansen for relief and for higher speeds.
The only foreigners on the Commission are British, Canadian, and Colombian, which may have something to do with the indifference to best industry practices. Bogota is famous for its BRT system, leveraging its wide roads and low labor costs, and Canada and to a lesser extent the UK have the same problems as the US in terms of best industry practices. Swiss, French, German, Japanese, Spanish, and Korean members might have known better, and might also have been useful in understanding where exactly the cost problems of the US in general and New York in particular come from.
The final major problem with the report, in addition to the indifference to cost, the proposal for reactionary funding sources, and the ignorance of best industry practices, is the continued emphasis on a state of good repair. While a logical goal in the 1980s and 90s, when the MTA was coming off of decades of deferred maintenance, the continued pursuit of the maintenance backlog today raises questions of whether maintenance has been deferred more recently, and whether it is still deferred. More oversight of the MTA is needed, for which the best idea I can think of is changing the cycles of maintenance capital funding from five years, like the rest of the capital plan, to one year. Long-term investment should still be funded over the long term, but maintenance should be funded more regularly, and the backlog should be clarified each year, so that the public can see how each year the backlog is steadily filled while normal replacement continues. This makes it more difficult for MTA chiefs to propose a bold program, fund it by skimping on maintenance, and leave for their next job before the ruse is discovered.
I tag this post under both good categories (“good transit” and “good/interesting studies”) and bad ones (“incompetence” and “shoddy studies”) because there are a lot of good ideas in the report. But none of them rises to the level of reinvention, and even collectively, they represent incremental improvement, of the sort I’d expect of a city with a vigorous capital investment program and industry practices near the world’s cutting edge. New York has neither, and right now it needs to imitate the best performers first.
Putting Rail Lines in Highway Medians
North Americans are in love with trains that go in highway medians. A large fraction of urban rail construction since World War Two, both light rail and full metro, has used highway medians as cheap at-grade rights-of-way to extend train service, often deep into the suburbs. Some proposed longer-range lines are supposed to go in medians as well: Florida had reserved space in the I-4 median for Orlando-Tampa high-speed rail, and Xpress West planned to go from Las Vegas to the outskirts of the Los Angeles area in the I-15 median. The Texas Central Railway, a private group backed by JR Central planning high-speed rail between Dallas and Houston, is considering several alignments, but markets the route as following I-45 (no mention of median) in some public discussions. In nearly all cases, both urban and intercity, it borders on incompetent to design rail lines in highway medians; intercity lines frequently follow highways on one side, but even that tends to be overrated in American discussions in my experience.
Urban Rail
For urban rail, the reason to use highways is that, in most of North America, they’re everywhere, and they’re usually equipped with generous medians and shoulders, allowing relatively cheap placement of rail tracks. Of note, this is generally not the cheapest option: construction on extant (often disused) rail rights-of-way tends to be cheaper. However, in many cases, a rail right-of-way is unavailable, hosts heavy freight traffic, has been permanently turned into a trail, or has commuter trains without integration into the rest of the urban transit network. Examples include the Dan Ryan half of the Red Line and both halves of the Blue Line in Chicago, the Orange and Silver Lines in Washington, the outer ends of BART, the Spadina line in Toronto, and several light rail lines. Often they run on one side of the road, but more frequently they’re in the median, which was often reserved for it when the road was built (as in Chicago and Calgary).
The problem is that nobody wants to live, work, or hang out next to a busy grade-separated road. Living or working a kilometer or two away, with easy access by car, is great for the driver, but within close walking distance, there is just too much noise, pollution, and blight, and the pedestrian environment is unwelcoming. The transit-oriented development in Metrotown and Arlington could not have happened next to a freeway. Christof Spieler frames this as a decision of spending more money on routing trains near where people live versus staying on the easy rights-of-way. But this isn’t quite right: the Expo Line in Vancouver was assembled out of an interurban right-of-way and a city center tunnel, both out of service; the line’s high ridership comes from subsequent development next to Metrotown and other stations.
Other times, the routing comes from a deliberate decision to integrate the trains with cars, with large park-and-rides at the ends. This is common on newer light rail systems in the US (though not Canada, as Calgary prefers integration with connecting buses) and in the Washington and San Francisco suburbs. This makes things even worse, by extending the radius within which the environment is built for cars rather than for people, and by encouraging the same park-and-ride construction elsewhere, along abandoned railroads and greenfield routes, where the preexisting environment is not car-oriented.
I do not want to categorically say that cities should never build urban rail alongside highways. But I cannot think of a single example in which this was done right. Calgary is a marginal case: it did build light rail along highways, and had some success with transit-oriented development, but those highways are arterials rather than freeways, and this makes the pedestrian environment somewhat better.
The situation is somewhat different for suburban rail, but usually the scale of suburban rail is such that there’s not much new construction, only reappropriation of old lines. These lines are long and the environments low-density, making it hard justify the costs of new lines in most cases. Where new suburban rail is built, for examples the Grand Paris Express, and various airport connectors, it is typically in environments with such expected traffic density that the rules for urban rail apply, and we tend to see more underground construction or usage of extant rights-of-way.
Intercity Rail
The reasons favoring highway alignments intercity rail in the US are somewhat different. Tellingly, HSR in Europe is frequently twinned with motorways. It is not about integration with cars, since those alignments are rarely if ever meant to have major stops in their middle. Instead, it’s about picking a pre-impacted alignment, where there are fewer property takings and fewer NIMBYs. This logic is sound, but I often see Americans take it to extremes when discussing HSR.
The first problem is that roads are almost never as straight as HSR needs to be. The design standards I have seen after briefly Googling give the radius of a motorway capable of about 120 km/h as, at a minimum, 500-700 meters. With these curves, trains, too, are capable of achieving about 120 km/h – less at 500 meters without tilting, more at 700 meters with tilting. The most recent high-speed lines are built with a minimum curve radius of 7 km; about the absolute minimum that can be done, with design compromises and tilting trains, is 4 km. This implies that the trains have to deviate from the motorway alignment whenever it curves. In flat regions the road curves are much gentler than the minimum, but still too sharp for full-speed running. Both Florida HSR and Xpress West noted that the trains would have to slow down whenever the Interstate curved, because the need to run in the median would prevent them from curving gently enough to maintain full speed.
Of note, the European examples of HSR running in motorway alignments have it running alongside the roads, not in the medians. I invite the reader to spend a few minutes following French LGVs on Google Maps and seeing this. This is because there invariably have to be small deviations from the road, which in a rural area are trivial when one runs next to the road but require viaducts when one runs between the road’s two carriages.
There may also be an issue regarding reusing the Interstates. To transit supporters who view HSR as a replacement for freeways, this has an element of poetic justice, or just plain practical reuse of infrastructure they think is obsolete. I chanced upon this while looking up Interstate design standards, but I’ve seen similar proposals elsewhere, as well as dissimilar proposals making use of interstate terminology, as a reminder of past national greatness. It comes from the same place as proposals to reuse auto factories to produce rolling stock: there’s a romantic aspect in addition to or instead of an economic one.
But the most fundamental problem is that the contentious experiences of the freeway revolts and modern-day NIMBYism have soured Americans on any process that involves brazen takings. What I mean by brazen is that carving a new right-of-way, especially through a populated area, looks obvious on a map. In contrast, sticking to a preexisting right-of-way and incrementally widening it or straightening curves is less controversial, even when it involves eminent domain as well, and opposition remains much more local, based on the specific properties being taken, rather than stated in general principles. I am not completely sure why this is so; my suspicion is that widening and straightening are more easily justified as things that must be done, whereas a new right-of-way looks gratuitous.
In either way, Americans have convinced themselves that NIMBYs are a major obstacle to infrastructure construction. While zoning is a notoriously NIMBY-prone process, infrastructure often isn’t. In the English common law world, expropriations are if anything easier than in France, where farmers are especially powerful, or Japan, where rioters threatened to block the construction of Narita Airport. NIMBYs are good at getting their names out in the media, but when it comes to blocking construction, they are relatively powerless; California HSR is facing NIMBYs in the Central Valley, many of whom are conservative and politically opposed to the project regardless of local impact, but so far they have not managed to delay construction.
However, NIMBYs are a convenient bogeyman for public projects, as their motives are openly selfish. They give charismatic, authoritarian leaders the opportunity to portray their infrastructure projects as battles between the common good and backward-looking parochial interests. As I’ve noted multiple times before, New York’s livable streets community (which is similar politically to the set of HSR supporters in the US) tends to overblow the importance of NIMBYs to the point of seeing NIMBYs even when the concerns have nothing to do with NIMBYism: see, for example, the reaction to the opposition of two Harlem politicians to a plan to speed up only the whitest bus route through the neighborhood.
California HSR Should Not Have Been Funded This Way
Last month, California made a budget deal for the formula that would be used to distribute its cap-and-trade revenues. The state’s cap-and-trade bill does not deed the money to the general budget but to a separate account, to be distributed based on a variety of goals including subsidies to programs that reduce greenhouse gas emissions. The recent deal is to give most of the money to transportation (including transit-oriented development): this year the budget gives $600 out of $850 million to transportation (see PDF-p. 6 here), of which $250 million will go to high-speed rail, and according to an informational hearing the long-term deal gives 80% of revenues to transportation, including 15% to high-speed rail. Transit bloggers who are not in the process of moving across oceans covered the issue last month as the deal was made: Streetsblog wrote about the plan, Robert Cruickshank wrote multiple times in support of the decision, and Bruce McFarling explained how HSR’s projected emissions reductions should entitle it to a share of the cap-and-trade proceeds.
In reality, although it’s a good thing that California HSR is getting funded, it’s a bad way of funding it, betraying both environmental incompetence and political mistrust. The basic problem is that the HSR project is not going to reduce emissions enough to justify 15% of the pot, nor is transportation such a big share of California’s emissions inventory to deserve 80%: it accounts for only 37% of statewide emissions. Electricity, and related sources of emissions such as building heating and industrial emissions, get far less than their share of emissions.
Bruce’s post runs the numbers on HSR, notes that the projections are currently $250-400 in construction costs per ton of CO2 reduction, and proposes that if cap-and-trade results in a carbon cost of $75 per ton then this justifies using the revenues for 20-35% of the cost of HSR. The projected revenue from cap-and-trade is a range whose top end is $5 billion statewide, corresponding to about $11 per metric ton; at this level, assuming HSR saves $250/t-CO2 means it should get 4.4% of its funding from emissions reduction, or (at the current cost of $53 billion in constant dollars) about $2.3 billion over the lifetime of the program. If the revenue is indeed $5 billion a year, this spending level is projected to be reached in 3 years.
For some evidence of what the state is really doing, consider how the deal comments on each share of the funding. The informational hearing details the investment strategy as follows:
25% for a permanent source of funding for transit operations, distributed based on greenhouse gas criteria.
20% for affordable housing and miscellaneous urban planning goals (including TOD), of which at least half must be for affordable housing (including TOD, again); the money is to be distributed based on “competitive GHG performance.”
15% low-carbon transportation, based on both long-term clean air and GHG goals.
13% energy, including electricity and building efficiency.
7% natural resources, waste diversion, and water projects.
15% HSR.
5% “new or existing” intercity rail, based on GHG criteria.
Note that internally to four categories, comprising 65% of the total funds, the hearing mentions greenhouse gas criteria. In three out of the four, comprising half of the funds, the hearing implies that the decision of how to distribute the funds will be based on competitive grants according to which project reduces emissions the most.
The key point here is that the state has effectively said what the best way is to ensure the spending side of cap-and-trade will reduce emissions optimally: projects will compete for scarce funding based on greenhouse gas criteria. Once it has made the political decision to distribute funds by a formula that disproportionately goes to transportation, it has no objection to using greenhouse gas criteria internally to each category. The problem is that the transportation projects in general and HSR in particular would never make it out of a grant process based on such criteria if they were not shielded from competition with non-transportation priorities.
There are two legitimate ways to distribute funds coming out of an externality tax, which is what cap-and-trade really is. One is to let the tax side do the work of reducing impact, and put the money into the general budget. This is common practice for most developed countries’ fuel taxes (though not the US’s). In this approach, HSR would compete with all of the state’s other budget priorities. If the state wanted to reduce other taxes against the cap-and-trade funds rather than raise spending, it could. If it wanted to spend the money on unrelated things, such as education, it could as well. There already is a more or less open and democratic budget process for this.
The other way is to reduce all political discretion, and distribute the funds based entirely on greenhouse gas criteria, without breaking the money into categories. The state seems to prefer this way, judging by its use of this process within each category. With other externality taxes there is another option, of giving the money directly to victims of the externality, e.g. spending cigarette taxes on lung cancer treatment; however, the bulk of damage caused by climate change is to developing countries, and spending cap-and-trade revenues on targeted aid to vulnerable developing countries is politically unacceptable.
The state’s hybrid approach is effectively a slush fund. High-level politicians, including Governor Jerry Brown, want to build a visible legacy, and HSR is far more visible than making household appliances consume less electricity. Emissions reductions are secondary to this concern. They’ll be happy to make their legacy a project that reduces greenhouse gas emissions, but they have no quantitative preference for projects that reduce emissions more than others. On the contrary, when they pull strings, they might even make decisions that make these projects less environmentally beneficial: the decision to connect Los Angeles to Bakersfield via Palmdale rather than directly has no technical merit, and judging by LA County’s support appears to be motivated by concerns for development in the Palmdale area. As the incremental cost of going through Palmdale is about $5 billion, nearly 10% of the HSR cost, the result is that the state is going to spend a substantial amount of cap-and-trade money on spurring more development in the High Desert exurbs.
Needless to say, when the cap-and-trade bill was passed, it did not state or even imply that the state could use the money to spur more development in the exurbs. The bill did not adopt a GHG-only approach, but listed several additional goals, none of which included transportation. Chapter 1, Part 2, paragraph h states,
It is the intent of the Legislature that the State Air Resources Board design emissions reduction measures to meet the state wide emissions limits for greenhouse gases established pursuant to this division in a manner that minimizes costs and maximizes benefits for California’s economy, improves and modernizes California’s energy infrastructure and maintains electric system reliability, maximizes additional environmental and economic co-benefits for California, and complements the state’s efforts to improve air quality.
There is an explicit mention of air quality, and explicit mentions of energy and electricity, which are only getting 13% of the funding despite accounting for 54% of emissions. Elsewhere the list of legislative intents includes vague terms such as technological leadership, but the only explicit mention of transportation in the bill is in paragraph c, which says that historically California provided leadership on several environmental issues, including emissions limits on cars as well as energy efficiency and renewable energy.
However, the cap-and-trade bill is older than the current administration, and the political priorities have changed. Since a regular budget process giving HSR the money it needs would run into opposition from competing priorities, it’s best to raid a new source of revenue, one without legislative inertia or established supporters directing the money to more useful purposes.
Hence, a slush fund.
What Elites Do Instead of Providing Services
I realized last year that even when they face a problem that is evidently about city services, city governments prefer to go for monuments that glorify their leadership. The most blatant example then was Cornell NYC Tech, the city-backed university whose campus construction alone is several times as expensive as the CUNY system per student. Since then I’ve tried to collect examples of power brokers proposing similar schemes, of which the worst is Larry Summers’ proposal to solve US inequality by spending public money on airport improvements. These are, to be frank, analogs of what American transit activists have to deal with routinely, with agencies preferring expensive iconic stations to ordinary capital and operating improvements in service.
The argument for Cornell NYC Tech is that New York needs tech entrepreneurs of the kind that Silicon Valley has, and that for that it needs its own Stanford. Instead of investing in STEM education across the CUNY system, or in its dedicated technological campus at the New York City College of Technology, it decided to start a private university from scratch, inviting other universities to bid on it. The city wanted Stanford to win the bid, but instead the winning bid was a joint effort by Cornell and the Technion, Israel’s technological university. The Technion was never run this way; it was started as a German-style technical university and is now a public university, funded and run on the same terms as the other Israeli public universities.
For Cornell NYC Tech, the city has lined up $2 billion in public and private funds for campus construction, expecting 2,000 students in 2037, which at 4% interest is $40,000 per student-year; annual capital and operating spending together, from all sources including tuition, is $16,000 per full-time equivalent student at the CUNY senior colleges and $11,000 at the CUNY community colleges (see PDF-page 65 of the budget request). This is the educational equivalent of airport connectors, which cities routinely spend several times per rider on as they would on ordinary subway extensions.
Summers’ proposal for airport improvements is in a way more frustrating, and more telling. He did not propose it as part of an independent infrastructure plan, but as a way to build public works to reduce US inequality, on the grounds that JFK is “an embarrassment as an entry point” and “the wealthiest, by flying privately, largely escape its depredations.” The proportion of people who fly privately is tiny; an income level at the bottom of the US top 1%, $400,000 per year, will buy you a lot of intercontinental business-class travel or some first-class travel, while affording a late-model Learjet requires an annual income of many tens of millions of dollars. Since poor people don’t fly as much as rich people, the users of JFK skew richer than the general city public.
My frustration comes from the fact that Summers is not trying to derail the conversation: he previously wrote about inequality as a problem and proposed standard center-left solutions, including raising taxes on capital gains and inheritances, supporting unionization, and (by implication) investment in public education. He clearly cares about the problem. He just seems to think that airport investment benefits the poor more than the rich. Most likely, this comes out of years of insider schmoozing with people so rich that they do own private jets, and generalizing to the considerably broader class of rich people.
In both cases, even on its stated merits, the proposal misses key facts about the situation. Silicon Valley began around Stanford, but once the initial tech cluster formed, it became independent of the university, so that even companies formed by people with no affiliation with Stanford or the Bay Area, such as Facebook, relocated to the area. New York is not going to grow its tech industry to the proportion of Silicon Valley’s by building an enterprise university any more than the Bay Area can become a world financial center by building affiliate universities for Columbia and NYU, from which many finance workers are recruited. As for JFK, like many of its users, when I arrive my first experience is the immigration line, a humiliating experience that involves fingerprinting and standing in line possibly for hours, depending on what terminal I use and what time I arrive. Public works will not solve that.
The problem with making even the merit-based argument is that public monuments are never truly merit-based projects. The decision-making process goes in the other direction: first the city elites (or, in case Summers’ proposal makes it into a national jobs bill, national elites) decide on something they want to see built, usually with the adjective world-class thrown in: a world-class university, a world-class airport, a world-class train station, a world-class office tower. The image of a world-class monument is more important than whether it works at its stated goal, such as improving education or transportation or fulfilling a need for class A office space.
Witness all the problems involving World Trade Center, which is being built entirely for prestige value, at enormous cost. The associated PATH station is $4 billion, almost as much as Second Avenue Subway, and about the same as 20 kilometers of subway in an average first-world city. One World Trade Center cost about $12,000 per square meter. I am not aware of any office tower in the world that is this expensive outside the WTC area and Hudson Yards; the tallest recent tower built in New York excluding 1 WTC, Bank of America Tower, cost about $5,500 per square meter in 2012 dollars, while the range I have seen for office towers in the 200+ meter range is about $2,500-6,000. Meanwhile, the WTC site struggles to find tenants: 1 WTC is almost half empty.
The sentiments after 9/11 ensured WTC would be rebuilt taller, regardless of actual demand in Lower Manhattan. Viewed through this lens, 1 WTC is not really about office space, but about proving a point about the power of US and New York to come back and not surrender to terrorism. This is why the transit spending went mainly to the PATH station and not to bringing the LIRR to Lower Manhattan, as proposed by the Regional Plan Association and studied officially in subsequent years: the LIRR project would’ve been about Lower Manhattan in general, without enhancing the specific prestige of WTC, while the billions poured into the WTC site and its PATH stations are all about the prestige.
Those other projects – various overrated transit schemes such as airport connectors, but also Cornell NYC Tech and Summers’ JFK proposals – are the same. They are not about what people living in, working in, or visiting the city need. They are not even about what they want. Whereas there was a citywide impulse to rebuild WTC taller after 9/11, there is no equivalent impulse to build an exclusive technical university, except among the power brokers. They are entirely about being able to say, “we have our own ___” and “I got that built.” It looks like development, but at best provides a fraction of the advertised value, and at worst provides nothing.
Whenever an urban project is proposed, the most important question to be asked is “what problem is this solving?”. Often, the problem is real, but there are much cheaper and less glamorous solutions. At other times, the project is a solution in search of a problem, and this is often detectable when proponents tout many unrelated benefits, almost as if the project can solve every major problem.
Compare this with solid public transit projects. Consider the lines I think North American cities should be focusing on, and the lines proposed in comments, especially as the Vermont subway in Los Angeles. In every single case, there are strong arguments for why the ridership of those lines would be high relative to the cost, and why existing subway lines (if any) and surface transit options are inadequate. The problem being solved is underserved neighborhoods with high transit demand, or in the case of the crosstown lines underserved origin-destination pairs in high demand. For other lines, not listed, there might be a separate argument regarding transit-oriented development: American cities tend to oversell TOD, as the problems with Hudson Yards show, but there do exist cases in which extending a subway line can allow dense development, or the construction of a new business district. But this involves figuring out where the development comes from – for example, the housing market may be very expensive, signaling high demand, or there may be projections of high future metropolitan population growth.
Usually, support for prestige projects to the exclusion of providing public services is the hallmark of moderates, along a broad arc from the center-left to the center-right. In the last few years, Republicans too far right to be called center-right have prioritized cutting taxes and spending and weakening the unions; signature projects conflict with their opposition to government spending. Conversely, urban leftist activists tend to oppose these prestige projects, on such grounds as gentrification, displacement, and private-sector involvement in public services.
The people in between those two ends are the ones most guilty of this kind of thinking. They are usually neo-liberal enough that they believe the government should champion market solutions and oppose industrial policy, and yet what they do is in many cases exactly industrial policy: Cornell NYC Tech is an attempt to curry favor with the technology industry. They are not so conservative as to believe government is always the problem, but the role they envision for government is to partner with the private sector to build public projects, which they tend to choose on grounds of what looks good rather than what provides the best public service. They know the buzzwords of urban politics well: for example, they’ll happily argue climate change to push a desired agenda that is usually only partly related to the problem, but lack the urgency of actual environmentalist activists and often also build roads and other dirty projects.
As with most bad things in politics, it’s a result of weak democratic institutions on the local level. American mayors tend to be elected dictators, and the opposition to them tends to be based on personality rather than ideology. In this non-ideological framework, the role of government is not to balance market and state solutions based on the voters’ preferences, but to aggrandize the leaders. Signature initiatives must appeal to the broad spectrum of non-ideological voters, so they can’t involve merely increasing spending on a chosen priority like education or transportation. Doing nothing is not an option – something has to be passed to remind people that the government still exists and has a purpose. The political incentives are against any incremental improvements that lead to tangible results, and for white elephants.
Underrated Transit Projects
In between the airport connectors and mixed-traffic streetcars are some public transit proposals that would be potentially high-performing. This is a list of potential lines in the US that don’t get nearly the exposure that they deserve.
The basic rule of this post is that if it’s being built, or is on an official urban wishlist pending finding the budget for it, then it’s not underrated. Some of the most important transit projects in North America are in this category: Second Avenue Subway’s current and future phases, the Regional Connector, the UBC SkyTrain extension. What I’m interested in is lines that are only vaguely on any official wishlist, if at all, but could still get very high ridership compared to their length. It is possible that these underrated lines would turn out to be worse-performing if a study were undertaken and the costs turned out to be very high, but in no case was there an honest study. Sometimes there has been no recent study; other times there is one but it sandbags the project.
Finally, I am not including commuter rail projects on this list. Under current regulations and operating practices, nearly all North American commuter rail projects are wastes of money. Conversely, nearly all projects that assume modernization of practices are underrated. This swing, based almost entirely on organizational question, is why I’m excluding these projects from this list. The subway and light rail projects below are less sensitive to organizational questions.
Utica Avenue Subway
Location: New York
Concept: an extension of the 4 from Crown Heights along Utica Avenue to Kings Plaza, about 7 km. If Second Avenue Subway’s Phases 3 and 4 are built, then a branch can be built from Second Avenue to Williamsburg and thence under Bushwick, Malcolm X, and Utica, taking over the entirety of the line, with the 4 cut back to its current terminus; this is an additional 9 km to Second and Houston.
Why it’s underrated: the second busiest bus route in New York, the B46, follows Utica: see here for New York bus route rankings. The busiest follows First and Second, which are getting a subway. Two additional routes in the top ten, the B44 and the B41, follow Nostrand and Flatbush respectively, fairly close to Utica. The B46 has 48,000 weekday riders and the B41 and B44 have another 70,000 between them. Since subways are much faster than city buses, the expected ridership is much higher than 120,000, measured in multiples rather than in a percentage increase. In addition, the 2, 3, 4, and 5 are all busier coming to the Manhattan core from Uptown than from Brooklyn, so adding to their ridership from the Brooklyn end balances the loads better, and avoids the required increase in operating costs for the new riders.
What is being done right now: nothing.
Geary Subway
Location: San Francisco
Concept: a full subway from Market Street to the Outer Richmond District, about 9 km. This can connect to the BART subway, the Muni Metro tunnel, or a second Transbay Tube if one is built.
Why it’s underrated: the 38-Geary is the busiest bus route in San Francisco, with 57,000 weekday riders between the local, the limited, and the express buses: see here for San Francisco bus ridership. Parallel corridors are also busy: the 1-California has 29,000, the 31-Balboa has 10,000, and the 5-Fulton has 17,000. Some of the census tracts along the middle of the route, in Little Osaka Japantown, rank together with Los Angeles’s Koreatown as the densest in the US outside New York. BART’s current limiting factor is not the Transbay Tube, but the grades farther south in San Francisco, which lengthen the braking distance and make it impossible to run a full 30 trains per hour through the core segments; a Geary branch leaving south of Montgomery Street would reduce service to points farther south, but improve capacity for riders heading from Oakland to the San Francisco CBD.
What is being done right now: there were never subway plans, but there were light rail plans, which due to local merchants’ opposition to loss of space for cars were downgraded to a rapid bus. The city’s FAQ on the subject even has the cheek to portray the Boston Silver Line and the Los Angeles Orange Line as successes.
Downtown Relief Line
Location: Toronto
Concept: there are several different alignments, but all feature an east-west line somewhere between Queen Street and Union Station, with one or two bends to the north to intersect the Bloor-Danforth Line. The latter two alignments (using option 4B for the second one) feature about 12 km of tunnel; I do not know how much the first one has.
Why it’s underrated: only one subway line serves Downtown Toronto, the Yonge-University-Spadina Line. Bloor-Danforth is too far from the CBD, and requires a transfer. The transfer points are very crowded: as far as I can tell from this list, the central one, Bloor-Yonge, has 200,000 weekday boardings, apparently including transfers. Without figures that include transfers in other cities I can’t make comparisons, but I doubt any two-line, four-track station in New York has this many riders. Union Station is quite crowded as well, and DRL proposals include transfers to outlying commuter rail stations. Ridership on parallel streetcars is very high: there are 53,000 on King Street, 44,000 on Queen, and, if a more northern alignment for the DRL is chosen, 32,000 on Dundas.
What is being done right now: more studies; construction will almost certainly begin any decade now. Neither David Miller’s Transit City light rail proposal nor Rob Ford’s replacement of Transit City with subways included the DRL.
125th Street Subway
Location: New York
Concept: either Phase 5 or Phase 2.5 of Second Avenue Subway, going west along 125th to Broadway, with a station at each intersection with an existing north-south subway.
Why it’s underrated: east-west transportation in Manhattan is slow, even by the standards of Manhattan buses. The 125th Street buses in my experience are slower than walking; despite this, the various routes have about 90,000 weekday boardings between them, of which about 30,000 come from 125th Street itself. Second Avenue Subway Phase 1 is going to substantially improve east-west transportation, by serving Times Square and offering a two-seat ride from the Upper East Side to the Upper West Side and Central and West Harlem; however, passengers from East Harlem will still have to take a major detour to avoid the crosstown buses. While SAS offers a relief to the 4/5 and 6 lines, the 2/3 and A/D express lines are overcrowded as well, and a connection at 125th Street would divert some East Side-bound commuters.
What is being done right now: nothing, although (some) railfans who work at the MTA privately want to see such a line built.
Silver Line Light Rail
Location: Boston
Concept: replacement of the Silver Line buses along Washington Street with light rail, feeding into an existing Green Line portal, about 4 km of light rail.
Why it’s underrated: the Silver Line buses are the busiest in Boston, with 15,000 weekday riders on the buses to Dudley Square: see PDF-pp. 47-48 of the MBTA Blue Book. The ridership doesn’t justify a subway, but does justify dedicated lanes and rail. The Green Line tunnel has some spare capacity, has a portal pointing in the correct direction, and could take an additional train every 6 or 7 minutes, which would give riders in Roxbury faster trips through Downtown Boston.
What is being done right now: nothing – a study sandbagged the rail bias factor and assumed only 130 new transit riders on a Silver Line light rail service, making the project appear cost-ineffective.
Triboro RX
Location: New York
Concept: a circumferential subway line, with about 1 km of new tunnel and 35 km of route on preexisting rights-of-way, abandoned or lightly used by freight trains today.
Why it’s underrated: the biggest cost driver, right-of-way formation, is already present. The right-of-way in question has a few daily freight trains, but the most critical link, the Hell Gate Bridge, is four-tracked, and freight trains can be kicked out from their segment of the bridge and moved to the Amtrak tracks. The work done by Michael Frumin and Jeff Zupan in the late 1990s estimated about 150,000 commute trips per weekday (76,000 commuters each making a roundtrip per day), which is low for a greenfield line of this length but reasonable for a line on existing rights-of-way.
What is being done right now: nothing, although ever since Lee Sander mentioned the line in 2008, politicians have paid lip service to the concept, without committing funding.
Boston Circumferential Line
Location: Boston
Concept: a circumferential subway, from Harvard Square to Dudley Square or the JFK-UMass subway stop, roughly following the 66 bus route where it runs and intersecting the busiest stops of the Green Line branches and some commuter rail stops. This is about 12 km.
Why it’s underrated: although the busiest Boston bus is the Silver Line to Dudley Square, the next few are circumferential, particularly the 1 and 66, and secondarily the 23 and 28; together this is about 50,000 riders. Boston’s street network is hostile to surface transit except on a few major streets such as Washington, which is why there is no hope of making such a line light rail, which would fit the projected ridership better. A route that parallels the 66, at least until it hits the E branch of the Green Line, would intersect the B, C, and D branches at their busiest respective surface stops, and improve connectivity to Cambridge, which is increasingly a major business district of the Boston region in its own right.
What is being done right now: BRT, on convoluted alignments that don’t exactly follow either the 66 or the 1 where they are parallel but instead make detours.
Nostrand Avenue Subway
Location: New York
Concept: an extension of the 2/5 from Flatbush to the southern end of Nostrand Avenue, about 5 km.
Why it’s underrated: all the reasons that make Utica so strong apply to Nostrand secondarily; the present bus ridership may be high enough to support two subway lines rather than one. The present terminus was built as a temporary one, which is why it has side platforms rather than an island platform.
What is being done right now: nothing.
Empire High-Speed Rail
At the beginning of the month, New York State released its draft environmental impact statement for high-speed rail from New York to the Upstate cities. The costs of HSR as proposed by the state are excessive, and as a result the state has eliminated the high-speed option. It is only considering medium-speed options – the fastest is 125 mph, for the cost of full-fat high-speed rail; it sandbagged the full-speed options. Consider the following passage, from the main document, section 3.2.2:
The dedicated right-of-way of the very high speed (VHS) alternatives would result in significant travel time savings (5:17 and 4:23 respectively for 160 mph MAS and 220 mph MAS), and commensurately higher estimated ridership (4.06 and 5.12 million respectively for 160 mph MAS and 220 mph MAS).
The length of New York-Buffalo is about 690 km. At 4:23, it is an average speed of 157 km/h. To put things in perspective, the Hikari express trains in the 1960s achieved an average of 162 km/h (515 km in 3:10) in 1965, with a maximum speed of 210 km/h.
In section 3.3.5, the 125 mph alternative, which involves greenfield dedicated track from Albany to Buffalo, is said to have an average speed of 77 mph, or 124 km/h. Considering that British express trains on the legacy East Coast and West Coast Main Lines restricted to the same top speed average about 130-140 km/h, this is unimpressive.
Likewise, the cost estimates seem too high. The cost proposed for 125 mph is $14.71 billion. That’s on existing track south of Albany with minor improvements; as per exhibits 3-19 and 3-21, 83% of the cost is said to be Albany-Buffalo, a distance of 380 km on new track plus 76 on existing track. This makes sense for a full-speed, 350 km/h line. But the cost of the full-speed 220 mph option is $39 billion, around $55 million per km from New York to Buffalo in an area with a topography that justifies at most half that.
The study also sandbags the higher-speed options, from 125 mph up, by overplaying the importance of skipped small cities. A greenfield line cannot reasonably serve Schenectady, Amsterdam, and Rome. It could serve Utica, but with some takings because the sharp curve from the tracks at the downtown station to the I-90 right-of-way to the west. Lack of service to Utica would be a drawback, but the study for some reason thinks that those four stations would need their own dedicated intercity line to New York, using a connection to Metro-North, which is said on PDF-p. 37 to have capacity problems on the Hudson Line (the Hudson Line runs 12 trains per hour at the peak today, and is four-tracked). I am told that people drive all the way from Watertown to Syracuse to take Amtrak; none of the skipped four stations is that far from Albany or Syracuse. If a regional train is needed, it can connect at Albany.
The problem is that the alignments studied are uninspiring. I don’t just mean it as a synonym for bad. I mean they avoid locations that look difficult at first glance but are actually reasonably easy. CSX bypasses Albany already; it is not a problem to run high-speed trains at low speed on the existing line between Rensselaer and a spot west of Albany where the line could transition to the Thruway, and yet exhibit 3-20 shows a passenger rail bypass of Albany.
For the full-speed option, I do not know how much tunneling and bridging the state thinks is necessary for its west-of-Hudson I-87 alignment from New York to Albany, but there’s an alignment east of the Hudson with only about 7 km of tunnel, all through the Hudson Highlands. Briefly, such a line would go east of the built-up area in Dutchess County and points north, with a possible station at the eastern edge of the Poughkeepsie urban area and another near Rhinebeck, closer to the city and to the bridge to Kingston than the present Rhinecliff station. In Putnam and northern Westchester Counties, it would utilize the fact that the ridge lines go northeast to southwest to swing to the southwest, to hook up to the Hudson Line slightly north of Croton-Harmon. With a curve radius of 4 km, and a maximum grade of 3.5%, only two tunnels are needed, one under Peekskill of about 2 km and one under the crest in Putnam County of about 5 km. Some additional viaducts are needed through the valleys in the Hudson Highlands, but from Dutchess County north the line would be almost entirely at-grade.
There is generally a tunnel vision in American high-speed rail documents like this, consisting of any of the following features:
– Excessive avoidance of greenfield alignments, even in relatively flat areas. The flip side is excessive usage of freeway rights-of-way. The Syracuse-Rochester segment is actually greenfield in the study, which is good, but there is no thought given to greenfield New York-Albany alignments, which are frankly much easier east of the Hudson than west of the Hudson.
– Questionable assumptions about the abilities of existing track in urban areas to have higher capacity, which often leads to excessive multi-tracking (as in California); there is never any effort to construct an integrated timetable to limit the construction of new tracks.
– No rail-on-rail grade separations. The study talks about Spuyten Duyvil capacity problems, which are very real if traffic grows, but says nothing about the possibility of grade-separating the junction from the Empire Connection to the Metro-North mainline to Grand Central.
– With the exception of California, which erred in the other direction, uninspiring speeds. It’s actually hard to construct a 350 km/h line that only averages 157; actual high-speed lines around the world in the 270+ range average about 180 or higher.
It’s not surprising New York is sandbagging HSR. A year and a half ago, the Cuomo administration killed an HSR study on the grounds that in a recession, the state can’t afford to build such an expensive project. Given how long it takes from the initial study to the beginning of construction, the argument is so transparently wrong that it raises the question of what the real motivation was. But whatever the real reason was, the state is not interested in HSR, and wrote a lengthy environmental impact study to justify its disinterest.
Metro-North-Everything Compatibility
The Regional Plan Association has a new study warning that Metro-North’s infrastructure is falling apart, and demands $3.6 billion in immediate spending on state of good repair. In general, my line on deferred maintenance is “you mean the agency deferred maintenance all those years and didn’t tell us?”. But in this case, despite the language, most of the proposed spending is improvements, namely rehabilitation or replacement of old movable bridges with low speed limits, rather than ongoing maintenance folded into long-term capital spending.
$2.8 billion of the proposed program is for replacing five bridges: Pelham Bay, Cos Cob (over the Mianus), Walk (over the Norwalk River), Saga (over the Saugatuck), and Devon (over the Housatonic). I believe all five should be replaced in the medium term, but the cost proposed is much higher than it should be. $560 million per bridge is quite high, and out of line with Amtrak found on PDF-pp. 29 and 56 of the Northeast Corridor Master Plan. Amtrak cites the cost of replacing the Pelham Bay Bridge alone at $100 million, and the cost of both replacing it and modifying curves on the Hell Gate Line at $500 million. It cites the cost of replacing both the Saga and Walk Bridges at $600 million.
Now, the RPA lists Saga as the easiest bridge to replace since it’s two two-track bridges, so work can be done one bridge at a time with less disruption to ongoing service, but conversely Pelham Bay is also quite cheap according to Amtrak.
But there’s a more serious problem, which is the avoidance of talking about service plans for commuter and intercity rail. If there is serious effort at adding Metro-North service to Penn Station or at raising intercity rail speeds, then the worst speed and capacity restrictions should get priority, and the infrastructure construction should be based on what promotes the desired service plans. It is very expensive and probably cost-ineffective to six-track everything from New Rochelle to Stamford, to allow three speed regimes: local, express, and intercity. I have argued before that it’s better to leave it at four tracks and bypass bad curves, around Port Chester, and make this the six-track segment. This is of course independent of maintenance issues, but suggests which bridge replacements are necessary to support these bypasses (Cos Cob) and which aren’t (the rest are less critical, especially Walk, which intercity trains should bypass on a straighter I-95 segment).
Likewise, there’s a capacity crunch west of Stamford but not one east of Stamford, and this again suggests Cos Cob as the most important priority. Finally, the slowest segment of the NEC away from immediate station areas is the western corner of Connecticut, from the state line to Stamford; Stamford’s curves are mild, while those heading out of Port Chester all the way across the Mianus are quite bad, and straightening the segment would also require straightening the bridge, which can be done easily if it’s replaced. Despite all this, the RPA and Amtrak are saying Cos Cob needs rehabilitation and not replacement, which misses opportunities to both improve reliability and speed up a slow segment.
Moreover, there is no mention of grade-separating Shell Interlocking, just south of New Rochelle. While not a state of good repair issue even in theory, the interlocking’s tight curves impose a limit of either 30 or 45 mph (so, 50-70 km/h), depending on source, in an area that could otherwise support 200 km/h or more. It is very difficult to straighten New Rochelle to sufficient curve radius for that, but 150 requires only minor takings. This may be necessary, independent of speed issues, to raise capacity enough to allow Metro-North service to both Grand Central and Penn Station. It’s possible to schedule trains through the flat junction, but this imposes an additional constraint on the schedule, on top of track-sharing with Amtrak and, in the East River Tunnels, the LIRR.
