How to Waste Money on Public Transportation
This is the fourth in a series of five (not four) posts about the poor state of political transit advocacy in the United States, following posts about the Green Line Extension in metro Boston, free public transport proposals, and federal aid to operations, to be followed by a post about how to do better instead.
I think very highly of Yonah Freemark. His academic and popular work on public transport and urbanism ranges from good to excellent, and a lot of my early thinking (and early writing!) on regional rail and high-speed rail owes a debt to him.
But I think he’s wrong in his proposal for a Green New Deal for transportation. This is a proposal by the Climate and Community Project (not the Urban Institute as I said in previous posts – sorry) to decarbonize transport in the United States, through fleet electrification and investments in public transport. Yonah is one of several authors; I identify him with the public transit-related parts of the report, but I want to make it clear that it’s the report I’m criticizing, regardless of who wrote what.
The fundamental problem of the CCP report is what I’ve been building up to in the last three posts in this series: it tries to please everybody by throwing money everywhere and making conflicting promises. The Green Line Extension was built this way under Deval Patrick, and costs ballooned, and what passed for discipline under Charlie Baker just reinforced the same long-term loss of state capacity that led to the cost explosion.
For example, here’s its take on fleet electrification:
In other words, there is a compelling and immediate need to decarbonize this fleet within a decade. And that’s feasible: buses are replaced every 10 to 15 years on average, and commuter rail trains about every 25 years; currently, commuter trains in the United States are on average 22 years old. Publicly owned vehicles would be replaced with the electric equivalent; for privately owned contracted vehicles (the case for many school buses), and requirements for electrification would be written into contracts and tax credits given to assist the transition of buses from fossil fuels to electric. The commissioning of thousands of new transit vehicles would produce new, good-paying union jobs in manufacturing. The shift to electric transit vehicles would affect maintenance requirements, and the Department of Transportation must ensure the mechanic and operator workforce is fully prepared for the electric transition through workforce retraining assistance. This may require retraining, such as encouraging mechanics to retrain as electric vehicle charging installers.
Electrifying existing diesel railways would require overhead catenary electrical wires to be useful for electrified trains (though the trains themselves actually cost less than diesel vehicles). The cost of railway electrification infrastructure alone is between roughly $1 and $5 million per mile. There are roughly 6,600 miles of non-electrified commuter rail in the United States, plus roughly 20,800 miles of non-electrified Amtrak service (with some overlap between the two). Amtrak’s routes are mostly owned by freight rail companies, but we suggest joint electrification that includes both passenger trains and freight trains, using this program for Amtrak and another we lay out below for the freight lines. To electrify the national passenger rail network of existing lines would cost between $27 and $137 billion. In addition, new trains would have to be purchased to run on these electrified lines.
I cite this pair of paragraphs because of something they show about the study: it is not uniformly bad. The second paragraph is a decent idea (though $1m/mile is very cheap), and trying to workshop how to wire the national freight network is not necessarily a bad idea, even if the report doesn’t go into enough detail about what the business barrier to electrification is for the private carriers.
But the first quoted paragraph is awful. Here’s the key thing: “The commissioning of thousands of new transit vehicles would produce new, good-paying union jobs in manufacturing” is a giant waste of money. Bus vendors outside North America consistently produce equipment for much less than the protected North American market; the Boris Bus, at £350,000 per unit (around $500,000), is both cheaper than American buses and locally considered expensive, a prime example of Boris Johnson’s poor performance as mayor of London.
The passenger rail industry does not exist in the United States, and attempts by American governments to coerce it to build factories domestically in order to create well-paying jobs have resulted in ballooning costs. The premium for recent American rolling stock orders, behind bespoke regulations, protectionism, informal state-level protectionism, and agency heads that know less than recently-graduated interns who make one quarter of what they do (less, if those interns are European), looks like 50% over European equivalents. Nor does this do much job creation, except perhaps for sitework consultants: the premium for some recent orders has been $1 million per $20/hour 4-to-6-year job created. Those are not objectively good jobs – the wages are not much higher than present-day retail, food service, and delivery jobs – but backward-looking politicians consider them inherently moral, and the report coddles them instead of looking forward.
Then, the report has the following recommendations for how to spend money on improving public transportation:
End the use of federal infrastructure funding for new highway infrastructure, except for focused opportunities that improve equity. Provide immediate funds for a quick-start infrastructure program for walking and cycling. Vastly expand support for transit and metropolitan network planning.
Appropriate $250 billion over 10 years, or $25 billion annually, in federal funding bill to support transit operations funding throughout the United States.
Increase federal support for transit and intercity rail capital projects to $400 billion over 10 years, or $40 billion annually, providing funds for new lines, maintenance of existing infrastructure, and upgrades designed for equitable accessibility.
Require metropolitan planning organization voting systems to be proportional to resident population. Mandate adjustments to local zoning policy to enable more dense, affordable housing near transit in exchange for federal aid. Implement regional commuter benefits throughout the nation.
This, I’m sorry, is a bad program. The $40 billion/year capital investment is not bad, but the proposal explicitly includes maintenance, making it vulnerable to the state of good repair scam, in which agencies demand escalating amounts of money for infrastructure with nothing to show for it. The $25 billion/year operating aid is likely to be a waste as well.
Transit agencies can invest money prudently, but the report says nothing about how to do it, instead proposing to zero out highway funding (which is a good way to save money, but is less relevant to mode shift than American transit advocates think it is). The one concrete suggestion for what to do with the money is “One goal, for example, would be for all residents to have access to a bus or train with a short wait within at most a 15-minute walk at all times of the day.” This is a standard I can get behind in a dense place like New York; nearly everywhere else, it means overfunding coverage routes in low-density areas, often middle-class white flight suburbs, ahead of workhorse urban routes. Writing years ago about New Haven, Sandy Johnston noted that a bus reform there would cannibalize the circuitous suburban bus branches to add service on the core routes through the city and Hamden. The CCP report would do the opposite, boosting frequencies where they are least useful.
Finally, the MPO rules seem weak. I get what Yonah (and perhaps the other authors) wants to do here: he wants to incentivize more housing production near mass transit nodes. But MPO voting weights are not especially relevant. What is relevant is using state power to disempower local communities, which are dominated by NIMBYs even in places where the residents vote YIMBY at the state level, such as San Francisco. The report talks about banning single-family zoning (okay, but duplexes are not TOD), but that’s it. Then it suggests extracting developer profits through mandatory inclusionary housing, which acts as a tax on TOD and reduces housing production. The authors of the study are left-wing, but do not propose public housing, only taxes on TOD to subsidize some local housing; Yonah knows this is not how social housing works in Paris, but he still proposes this for the United States.
The theme of lack of willingness to prioritize flow throughout these recommendations. There is no discussion of how to prioritize good investments, how to increase efficiency (the report points out operating costs for all US transit combined are $50 billion/year; this is 2.5 times the German level, for similar ridership, not per capita), how to make sure that progress does not get extracted by programs for groups thought inherently moral.
Quick Note: the LaGuardia Transit Connector
It’s amazing how much good can happen when an obstacle like Andrew Cuomo is removed. In lieu of his backward air train proposal, hated by just about everyone not on his payroll, Governor Kathy Hochul is moving forward on a better set of alternatives for a mass transit connection to LaGuardia. It’s interesting to see what the process is looking at but also what it isn’t; so far this looks better than the alternatives analysis for Interborough Express (ex-Triboro).
So far I have not seen analysis, only drawings of 14 alternatives. As with the IBX study, the LGA plan distinguishes different modes of public transit – there are bus, light rail, subway, and even ferry options. But it doesn’t stop there. It looks at multiple alignments: the scope is how to connect LGA to the rest of the city the best, and this can be done from a number of different directions – even a backward train (as light rail) along an alignment similar to Cuomo’s is present, and will likely not advance further because of its circuitous route.
Among the 14 alternatives, I think the obviously best one is a subway extension (slide 12 above); another subway option, a branch following the Grand Central Parkway (slide 11), is inferior because of branching splits frequencies and ridership at the cut off Astoria-Ditmars Boulevard station is high. A subway extension promises a connection in around 30 minutes to Times Square, every 5 minutes all day, with good connections to other destinations via the transfers at Queensboro Plaza and in Midtown.
The one thing that I’m sad the analysis hasn’t looked at is intermediate stations. It’s around 4.5 km from Ditmars to the main LGA terminal along the proposed alignment, passing through redevelopable industrial land and through residential land in Astoria Heights awkwardly tucked between airport grounds and Astoria proper. The same quality of service that the airport could get, these neighborhoods could get as well, except a hair faster because they’re closer.
Extending the Astoria Line is especially useful since it is short and not especially crowded until it hits Queensboro Plaza and inherits the crowding of the 7 train and its riders. In the context of deinterlining the subway, this is especially valuable: right now 60th Street Tunnel carries the N and W from Astoria but also the R from Queens Boulevard, and under deinterlining the tunnel would carry only Astoria riders, and so to match the high demand to 60th Street it’s valuable to create as much ridership as possible on the Astoria Line past Queensboro Plaza.
I hope that the alternatives analysis considers multiple stopping patterns in the future – that is, not just a nonstop route from Ditmars to the airport, but also an option with intermediate stations. (This does not mean local and express trains – either all trains should run locals, or all should run nonstop.) The cost of those stations is not high as it’s an elevated line, and the stop penalty on the subway is less than a minute since the top speed is so low (it looks like 45 seconds in practice comparing local and express trains on the same line).
The Interborough Study
I was excited about the idea of Interborough Express (IBX) as announced by New York Governor Kathy Hochul, and then last week her office released a preliminary report about the alternatives for it, and I got less excited. But it’s not that the study is bad, or that Hochul is bad. Rather, the study is a by the numbers alternatives analysis, shorter than the usual in a good way; its shortcomings are the shortcomings of all American planning.
The main rub is that the report looks at various options for the IBX route, broken down by mode. There’s a commuter rail option, which bakes in the usual bad assumption about commuter rail operations, including heavier trains (lighter trains are legal on US tracks as of 2018) and longer dwell times that are explained as a product of the heavier trains (dwell times have nothing to do with train mass). That’s par for the course – as we saw yesterday, everything that touches mainline rail in North America becomes stupid even in an otherwise understandable report.
But even excluding commuter rail, the study classifies the options by mode, focusing on bus rapid transit and light rail (and no subway, for some reason). It compares those two options and commuter rail on various measures like expected ridership and trip times. This is normal for American alternatives analyses for new corridors like IBX: they look at different modes as the main decision point.
This is also extraordinarily bad governance. There are some fundamental questions that are treated as afterthoughts, either not studied at all or mentioned briefly as 1-2 sentences:
- How far north should the line go? The IBX plan is to only go from Jackson Heights to the south, in contrast with older Triboro proposals going into the Bronx.
- What should the stop spacing be? The stops can be widely spaced, as in the current proposal, which stops mainly at intersection points with other lines, or more closely spaced, like an ordinary subway line.
- Under a light rail option, should the line be elevated where the trench is too narrow or at-grade?
- Should freight service be retained? What are the benefits of retaining freight rail service on the Bay Ridge Branch and what are the incremental costs of keeping it versus taking over the right-of-way?
- How large should the stations be?
- How frequent should the trains be? If freight service is retained, what frequencies are compatible with running freight on the same tracks for part or all of the line?
A better study must focus on these questions. Some of them, moreover, must be decided early: urban planning depends on whether the line goes into the Bronx or not; and industrial planning depends on what is done with freight service along the corridor.
Those questions, moreover, are more difficult than the modal question. A BRT option on a rail corridor without closely parallel arterial roads should be dismissed with the same ease that the study dismisses options not studied, and then the question of what kind of rail service to run is much less important than the scope of the project.
But American planning is obsessed with comparing public transit by mode rather than by corridor, scope, or any other aspect. Canadian planning has the same misfeature – the studies for the Broadway SkyTrain extension looked at various BRT and light rail options throughout, even though it was clear the answer was going to be SkyTrain, and omitted more fundamental questions regarding the cost-construction disruption tradeoff or even the scope of the project (the original studies from 2012 did not look at truncating to Arbutus, an option that had been talked about before and that would eventually happen due to cost overruns).
So overall, the IBX study is bad. But it is interestingly bad. Andrew Cuomo was a despicable governor who belongs in prison for his crimes. Less criminal and yet similarly loathsome people exist in American public transit. And yet, Hochul and her office are not like that, at all. This is not a sandbag, or a corrupt deal. It’s utterly ordinary in its failure; with all the unique failures of the Cuomo era stripped, what is left is standard American practice, written more clearly than is usual, and it just isn’t up to par as an analysis.
Hochul has been moving on this project very quickly, and good transit advocates should laud this. It should not take long to publish a report comparing alternatives on more fundamental questions than mode, such as scope, the role of freight, and the extent of civil infrastructure to be used. The costs and benefits of IBX heavily depend on the decisions made on such matters; they should not be brushed aside.
New York Publishes a Bad Benchmarking Report
I’ve grown to intensely dislike benchmarking reports. It’s not that the idea of benchmarking bad. It’s that they omit crucial information – namely, the name of the system that one is compared with. The indicators always have a wide variety of values, and not being able to match them with systems makes it impossible to do sanity-checks, such as noticing if systems with high costs per car-km are consistently ones that run shorter trains. This way, those anonymized reports turn into tools of obfuscation and excusemongering.
The MTA in New York recently published such a report, including both US-wide and international benchmarking for the subway as well as commuter rail. The US benchmarking is with comparable American systems – exactly the ones I’d compare, with the systems listed by name as NTD data is wisely not anonymized. The international benchmarking for the subway is with CoMET, which includes most of the larger global systems as well as a handful of smaller ones, like Vancouver; for commuter rail, it’s with ISBeRG, which has an odd list of systems, omitting the RER (which is counted in CoMET), all of Japan except JR East, and any S-Bahn, skipping down to Australian systems, Cape Town, and Barcelona.
That, by itself, makes much of the international benchmarking worthless. The standard metric for operating costs is per car-km. This is covered in pp. 8-9, showing that New York has fairly average costs excluding maintenance, but the second highest maintenance costs. But here’s the problem: I’m seeing a comparison to an undifferentiated mass of other systems. One of them is an outlier in maintenance costs, even ahead of New York, but I do not know which it is, which means that I cannot look at it and see what it does wrong – perhaps it has an unusually old fleet, perhaps it is small and lacks scale, perhaps it is domestically viewed as scandal-ridden.
Far more useful is to look at complete data by name. For example, JICA has complete operating cost data for Japanese metro systems. Its tables are complete enough that we can see, for example, that overall operating costs are around $5/car-km for all systems, regardless of scale; so scale should not be too important, or perhaps Tokyo’s wealth exactly cancels out the scale effect. There are, on table 2.37 on PDF-p. 117, headcounts for most systems from which we can impute labor efficiency directly, using train-km data on PDF-p. 254; Yokohama gets 1,072 train-hours a year per driver at 35 km/h (the rough average speed I get from Hyperdia).
And here’s the thing: without the ability to fill in missing data like average speed, or to look at things the report didn’t emphasize, the report is not useful to me, or to other independent researchers. It’s a statement of excuses for New York’s elevated operating and maintenance cost, with officious proclamations and intimidating numbers.
For example, here’s the excuse for high maintenance costs:
High maintenance costs for NYCT are largely attributable to 24-hour service. Most COMET peer agencies shut down every night, allowing for four hours of continuous daily maintenance. In comparison, NYCT subway’s 24-hour service requires maintenance to occur within 20-minute windows between late night trains, reducing work efficiencies. Additionally, maintenance costs for NYCT have risen recently to support the improvements as part of the Subway Action Plan, which have led to a significant improvement to on-time performance year over year since inception.
Okay, so here we’re seeing what starts like a reasonable explanation – New York doesn’t have regular nighttime maintenance windows. But the other American systems studied do and they’d be above global average too; Boston has regular nighttime work windows but still can’t consign all track maintenance to them, and has almost the same maintenance cost per car-km as New York. Moreover, track maintenance costs per car-km should feature extensive scale effects – only at freight rail loads is the marginal track wear caused by each additional car significant – and New York runs long trains.
Then there is the Subway Action Plan line, which is a pure excuse. Other systems do preventive maintenance too, thank you very much. New York is not unusually reliable by global standards, and the benchmarking report doesn’t investigate questions like mean distance between failures or some measure of the presence of slow restrictions – and because it is anonymized, independent researchers can’t use what it does have and get answers from other sources.
The study has a section on labor costs, showing New York’s are much higher than those of some peer cities. Thankfully, that part is not anonymized, which means I can look at the cities with overall labor costs that are comparable to New York’s, like London, and ignore the rest; New York’s construction labor costs are higher than London’s by a factor of about 2, despite roughly even regionwide average wages. Unfortunately, a key attribute is missing: labor efficiency. The JICA study does better, by listing precise headcounts; but here the information is not given, which means that drawing any conclusion that is not within the purview of MTA’s endless cold war on its unions is not possible. As it happens, I know that New York is overstaffed, but only from other sources, never anonymized.
It’s worse with commuter rail. First of all, at the level of benchmarking, the study’s list of comparisons is so incomplete and so skewed (three Australian systems, again) that nothing it shows can be relevant. And second, commuter rail in North America comes with its own internal backward-looking culture of insularity and incompetence.
The report even kneecaps itself by saying,
While it is true that benchmarking provides useful insights, it is also important to acknowledge that significant differences exist among the railroads that pose challenges for drawing apples-to-apples conclusions, particularly when it comes to comparisons with international peers. Differing local economies, prevailing wages and collective bargaining agreement provisions can have dramatic impacts on respective labor costs. Government mandates, including safety regulations, vary widely, and each railroad exists in a unique operating environment, often with different service schedules, geographic layouts and protocols. Together these factors have also have a significant impact on relative cost structures.
To translate from bureaucratic to plain English, what they’re saying is that American (and Canadian) practices for commuter rail are uniquely bad, but controlling for them, everything is fine. The report then lists the following excuses, all of which are wrong:
• Hours of Operation: LIRR provides 24 hours of service 7 days per week, and MNR provides 20-22 hours of service 7 days a week
• Ungated System: Neither LIRR nor MNR operate gated systems, therefore they require onboard fare validation/collection
• Branch Service: Both LIRR and MNR run service to and from a central business district (New York City) and do not have ability to offer through-running service
• Electrification: Both LIRR and MNR operate over both electrified and non-electrified territory, thereby requiring both electric and diesel fleets
It’s impressive how much fraud – or, more likely, wanton indifference and incuriosity – can fit into just four bullet points. Metro-North’s hours of service are long, but so are those of the JR East commuter lines; the Yamanote Line runs 20 hours a day, which means the nighttime maintenance window is shorter. Ungated systems use proof-of-payment ticketing throughout Europe – I don’t know if Rodalies de Catalunya runs driver-only trains, but the partly-gated RER and the ungated S-Bahns in the German-speaking world do. Through-running is a nice efficiency but not all systems have it, and in particular Melbourne has a one-way loop system akin to that of the Chicago L instead of through-running. Finally, electrification on the LIRR and Metro-North is extensive and while their diesel tails are very expensive, they also sometimes exist in Europe, including in London on a line that’s partly shared with the Underground, though I don’t know if they do in the report’s comparison cases.
The report does not question any of the usual assumptions of American mainline rail: that it must run unusually heavy vehicles, that it run with ticket-punching conductors, etc.
For a much more useful benchmarking, without anonymization, let’s look at German S-Bahns briefly. There is a list of the five largest systems – Berlin, Munich, Hamburg, Frankfurt, Stuttgart – with ridership and headcounts; some more detail about Berlin can be found here. Those five systems total 6,200 employees; the LIRR has 7,671 and Metro-North 6,773. With 2,875 employees, the Berlin S-Bahn has more train-hours than the LIRR, Metro-North, and New Jersey Transit combined; about as many car-km pro-rated to car length as the LIRR times 1.5; and more ridership than all American commuter rail systems combined. The LIRR in other words has more workers than the largest five German S-Bahns combined while the Berlin S-Bahn has more riders than all American commuter rail systems combined.
The excuses in the report highlight some of the reasons why – the US sticks to ticket-punching and buys high-maintenance trains compliant with obsolete regulations – but omits many more, including poor maintenance practices and inefficient scheduling of both trains and crew. But those are not justifications; they are a list of core practices of North American commuter rail that need to be eliminated, and if the workers and managers cannot part with them, then they should be laid off immediately.
Platform Edge Doors
In New York, a well-publicized homicide by pushing the victim onto the subway tracks created a conversation about platform edge doors, or PEDs; A Train of Thought even mentions this New York context, with photos from Singapore.
In Paris, the ongoing automation of the system involves installing PEDs. This is for a combination of safety and precision. For safety, unattended trains do not have drivers who would notice if a passenger fell onto the track. For precision, the same technology that lets trains run with a high level of automation, which includes driverless operations but not just, can also let the train arrive with meter-scale precision so that PEDs are viable. This means that we have a ready comparison for how much PEDs should cost.
The cost of M4 PEDs is 106 M€ for 29 stations, or 3.7M€ per station. The platforms are 90 meters long; New York’s are mostly twice as long, but some (on the 1-6) are only 70% longer. So, pro-rated to Parisian length, this should be around $10 million per station with two platform faces. Based on Vanshnook’s track map, there are 204 pairs of platform faces on the IRT, 187 on the IND (including the entire Culver Line), and 165 on the BMT (including Second Avenue Subway). So this should be about $5.5 billion, systemwide.
Here is what the MTA thinks it should cost. It projects $55 million per station – but the study is notable in looking for excuses not to do it. Instead of talking about PEDs, it talks about how they are infeasible, categorizing stations by what the excuse is. At the largest group, it is accessibility; PEDs improve accessibility, but such a big station project voids the grandfather clause in the Americans with Disabilities Act that permits New York to keep its system inaccessible (Berlin, of similar age, is approaching 100% accessible), and therefore the MTA does not do major station upgrades until it can extort ADA funding for them.
Then there is the excuse of pre-cast platforms. These are supposed to be structurally incapable of hosting PEDs; in reality, PEDs are present on a variety of platforms, including legacy ones that are similar to those of New York, for example in Paris. (Singapore was the first full-size heavy rail system to have PEDs – in fact it has full-height platform screen doors, or PSDs, at the underground stations – but there are later retrofits in Singapore, Paris, Shanghai, and other cities.)
The trains in New York do not have consistent door placement. The study surprisingly does not mention that as a major impediment, only a minor one – but at any rate, there are vertical doors for such situations.
So there is a solution to subway falls and suicides; it improves accessibility because of accidental falls, and full-height PSDs also reduce air cooling costs at stations. Unfortunately, for a combination of extreme construction costs and an agency that doesn’t really want to build things with its $50 billion capital plans, it will not happen while the agency and its political leaders remain as they are.
The TransitMatters Rail Electrification Report
At TransitMatters, we’ve just released a report about the costs and benefits of rail electrification. It’s anchored to our proposal to electrify and modernize the commuter rail system in the Boston area, but much of the analysis is broader than that. The non-Bostonian reader may still be interested in the description of construction costs of electrification and the short case studies of Israel, Denmark, Norway, New Zealand, Britain, Canada, and the United States. The latter two, covering Toronto and the Bay Area, are unusually expensive and we go over why that came to be and how it is possible to avoid them. The section on alternatives and why they are all inferior to stringing wire and running EMUs is of general interest as well, and I hope European policymakers read over and take it as a sign they should electrify more lines (ideally, all of them, as is being done right now in South Korea, India, and China).
The Toronto problem
When we came up with the cost range of $800 million to $1.5 billion, there was a lot of skepticism. The Reddit thread‘s two most common kinds of comment are “great, this can’t happen fast enough” and “it will cost billions because of unspecified MBTA problems.” As I said in responding to one of the comments, the higher-cost comparison cases all have specific reasons for their higher costs: Britain has clearance restrictions that do not exist anywhere else in the world, and Caltrain had unusual managerial incompetence regarding the related signaling project where the MBTA is actually doing well. But Toronto still looms large.
As I said on Reddit,
I’m not too worried about Caltrain’s errors, which were truly bespoke. Toronto worries me more, because while the specifics are avoidable, the ultimate cause is reproduced: Toronto and Boston are both huge cities with heavy peak commuter rail traffic and should have electrified generations ago, so now the benefits of electrification are so high that managers can afford to be careless about costs and still have above-water benefit-cost ratios.
So it is important to be careful and avoid Toronto’s problems with cost control. This means baking cost control into the program from the start, and aggressively protecting the budget from use by other actors as OPM:
- The budget should be set at a standard level with standard contingencies. Do not aim for the ceiling; aim for average. Nor should anyone include 100% contingency as used by Toronto; if you budget money for the project it will be used, so optimize for minimizing overall cost rather than for just-in-case funding.
- Designs should be standard, and variations should be accommodated only based on cost minimization. Basically, if it’s good enough for Germany, France, Denmark, Norway, Israel, etc.,, it’s good enough for the United States.
- If NIMBYs push back, the state should fight back. They want noise walls? Nope, EMUs are a lot quieter than diesels, quality of life will improve. They want trenches? Nope, that’s too expensive.
- Under no circumstances should passenger rail electrification money be used for corporate welfare for freight rail companies. They can pay their own way for clearance for double-stacked containers.
The importance of maximum electrification
Based on the observations that the lifecycle costs of DMUs are about twice those of EMUs, and that operating and capital costs are both driven by the peak rather than off-peak, it’s possible to establish financial rates of return on electrification. Not counting the speed and reliability benefits to passengers, the ROI is around 0.3-0.5% per US-size car per hour at the peak. Lines that run 8-car trains every 15 minutes at rush hour run 32 cars per hour and so have an ROI of 10-16%; this is why outside the US and Canada, cities that run such long trains at such frequency have long electrified their tracks.
The problem is that electrification is relatively unfamiliar in North America. It exists, but is sporadic, and there have been very few recent projects, so managers think it’s a Herculean task. In Boston I’ve seen reticence to wire more track due to institutional conservatism, even in plans that spend comparable amounts of money on things the region is more used to, like station platform upgrades and extra tracks. Worse, I’ve seen this in New Jersey, which is largely already electrified but uninterested in finishing the job.
Against such conservatism, it’s important to remember that failure to undertake a high-value investment isn’t any more moral than a large investment that goes to waste. When your ROI hits double digits, you waste public benefits by avoiding or even just delaying the project – and the above calculation comes just from savings on operating, maintenance, and capital acquisition costs, without the large benefits to passengers, the environment, etc.
Can large cities afford not to electrify? Yes. They have money for many kinds of waste, including for forgoing the benefits of commuter rail electrification. But just because they can afford to waste money and social benefits doesn’t mean they should. So, please, no talk of DMUs, or bi-modes, or pilot programs, or batteries – just wire your system already and import some high-quality EMUs.
I want to go back to the problem of early commitment as I explained it two months ago. It comes out of research done by Chantal Cantarelli and Bert van Wee about Dutch cost overruns, but the theory is more generally applicable and once I heard about it I started seeing it in play elsewhere. The short version is that politically committing to a megaproject too early leads to lock in, which leads to compromised designs and higher costs. The solution, then, is to defer commitment and keep alternatives open as much as possible.
The theory of lock in
The papers to read about it are Cantarelli-Flyvbjeerg-Molin-van Wee (2010), and Cantarelli-Oglethorpe-van Wee (2021). Both make the point that when the decision to build is undertaken, it imposes psychological constraints on the planners. They are not long or difficult papers to read and I recommend people read them in full and perhaps think of examples from their own non-Dutch experience – this problem is broader than just the Netherlands.
For example, take this, from the 2010 paper:
Decision-makers show evidence of entrapment whenever they escalate their commitment to ineffective policies, products, services or strategies in order to justify previous allocations of resources to those objectives (Brockner et al, 1986). Escalating commitment and justification are therefore important indicators of lock-in. The need for justification is derived from the theories of self-justification and the theory of dissonance which describe how individuals search for confirmation of their rational behaviour (Staw, 1981; Wilson and Zhang, 1997). This need arises due to social pressures and “face-saving” mechanisms. The involvement of interest groups and organizational pushes and pulls can also introduce pressures into the decision-making process, threatening the position of the decision-makers, who may feel pressure to continue with a (failing) project in order to avoid publicly admitting what they may see as a personal failure (McElhinney, 2005). “People try to rationalize their actions or psychologically defend themselves against an apparent error in judgment” (Whyte, 1986) (“face-saving”). When the support for the decision is sustained despite contradicting information and social pressures, the argumentation for a decision is based on the need for justification.
The focus on face-saving behavior leading to escalation is not unique to the literature on transportation. In international relations, it is called audience cost and refers to the domestic backlash a political leader suffers in case they back down from a confrontation they were involved in earlier; this way, small escalations turn into bigger ones and eventually to war, or perhaps to a forever occupation.
There are a number of consequences of lock in:
- Projects will follow designs set long ago, especially ones that were hotly contentious. For example, California High-Speed Rail has stuck with the decision to build its alignments via Palmdale and Pacheco Pass, since the possibilities of changing Palmdale to the Grapevine/Tejon alignment and Pacheco to Altamont Pass both loomed large (there was a NIMBY lawsuit trying to force a change to Altamont). However, at the same time, there are plans to potentially run the partially-built system without electrification, since that issue was never in contention and is not part o the audience cost.
- There are unlikely to be formal cancellations. California is again a good example: high-speed rail lives as a hulk, not formally canceled even when the governor said of the idea to complete it, back during the Trump administration, “let’s be real,” defending the initial construction segment between Bakersfield and Fresno as valuable in itself. Formal cancellation is embarrassing; a forever construction project is less visible a failure.
- Prioritization is warped to tie into real or imagined connections with the already-decided project. California is not as clear an example of this as of the other two points, but in New York, once the real (if not yet formal) decision to go forward with Second Avenue Subway was made in the 1990s, the Regional Plan Association tied in every proposed expansion plan to that one line.
Cantarelli-van Wee treat early commitment as a problem of bad planners, who become psychologically wedded to potentially incorrect solutions. However, it is instructive to shift the locus of moral blame to surplus extraction by political actors, such a local politicians, power brokers, and NIMBYs.
In the story of HSL Zuid, much of the extra cost should be blamed on excessive tunneling. In the flat terrain of Holland and near-coastal Brabant, no tunneling should have been needed. And yet, the line is 20% underground, partly to serve Schiphol, partly to avoid taking any farmland in the Groene Hart. The Groene Hart tunneling has to be understood in context of rural NIMBYism (since at-grade solutions to habitat loss exist in France).
In this formulation, the problem with lock in is not just at the level of planners (though they share most of the blame in California). It’s at the level of small actors demanding changes for selfish reasons, knowing that the macro decision has already been made and the stat cannot easily walk away from the project if costs rise. These selfish actors can be NIMBY, but they can equally be local power brokers wanting a local amenity like a detour to serve them or a station without commercial justification. In Germany, an extra layer of NIMBYism (albeit not on connected with lock in – we have late commitment here) is demands to include freight on high-speed lines, in order to take it off legacy lines, which design forces gratuitous tunneling on high-speed lines in order to moderate the grade.
California is a good example of a non-NIMBY version of this. The state politically committed to building high-sped rail in the 2008 election, for which it showed clear maps of the trains detouring via Palmdale and going to San Francisco via Pacheco Pass. By the time further environmental design showed that the Los Angeles-Palmdale route would require tens of km more tunneling through Soledad Canyon than anticipated to avoid impact to an ecologically sensitive area, the state had already pitched Palmdale as a key high-speed commuter suburb, and Los Angeles County made housing plans accordingly. The county subsequently kept agitating for retaining Palmdale even as other alignment changes in the area were made, turning Palmdale into its pet project.
The planning literature undertheorizes and understudies problems arising from localism. In conversations with people in the European core as well as the United States, there’s an unspoken assumption that the community is good and the state is bad. If the community demands something, it must represent correction of a real negative externality, rather than antisocial behavior on behalf of self-appointed community leaders who the state can and should ignore. It doesn’t help that the part of Europe with the least community input is the Mediterranean countries, which Northern European planners look down on, believing any success there must be the result of statistical fudging.
The solution: late commitment
To reduce costs and improve projects, it’s best to delay political commitment as late as possible. This means designing uncertain projects and only making the decision to build at advanced stages of design – maybe not 100% but close enough that major revisions are not likely. The American situation in which there is no regular design budget so agencies rely on federal funding for the design of the projects they use the same federal funding for leads to bad outcomes over and over. California, which went to referendum without completing the environmental design first, takes the cake.
Late commitment is thankfully common in low- and medium-cost countries. Germany does not commit to high-speed rail lines early, and, judging by Berlin’s uncertainty over which U-Bahn extensions to even build, it doesn’t commit to subways early either. Sweden is investigating the feasibility of high-speed rail but rail planners who I talk to there make it clear that it’s not guaranteed to happen and much depends on politics and changes in economic behavior; overall, Nordic infrastructure projects are developed by the civil service beyond the concept stage and only presented for political negotiation and approval well into the process. Southern European planners com up with their own extension programs and politically commit close to the beginning of construction.
Do Costs Run Over or Are They Underestimated?
The literature on cost overruns for infrastructure projects is rich, much more so than that for absolute costs. The best-known name in this literature is Bent Flyvbjerg, who in the early 2000s collated a number of datasets from the 1980s and 90s to produce a large enough N for analysis, demonstrating consistent, large cost overruns, especially for urban rail. Subsequently, he’s written papers on the topic, focusing on underestimation and on how agencies can prospectively estimate costs better and give accurate numbers to the public for approval. This parallels an internal trend in the US, where Don Pickrell identified cost overruns in 1990 already, using 1980s data; Pickrell’s dataset was among those analyzed by Flyvbjerg, and subsequent to Pickrell’s paper, American cost overruns decreased to an average of zero for light rail lines.
But a fundamental question remains: are cost overruns really a matter of underestimation, or a true overrun? In other words, if a project, say Grand Paris Express, is estimated to cost 22.6 billion € in 2012 (p. 7) and is up to 35.6 billion € today (p. 13), does it mean the cost was 35.6b€ all along and the 2012 analysis just failed to estimate it right? Or dos it mean the cost was 22.6b€ then, and then the budget ran over due to failures of planning that could have been avoided?
Transit agencies that just want to avoid the embarrassment of media headlines saying “they said it costs X but it costs 2X” care mostly about underestimation. This is also true of both generic project managers and political appointees, two groups that do not care about the details of how to build a subway, and think of everything in abstract terms in which a subway might as well be a box of shampoo bottles.
However, the concrete examples that I have seen or heard of for cost overruns look like overruns rather than underestimation. That is, those projects could have been done at the original cost, but planning mistakes drove the budget up, or otherwise created conditions that would enable other forces to drive the budget up.
The Netherlands: early commitment
Bert van Wee is among the world’s top researchers on cost overruns, even if he’s less well-known to the public than Flyvbjerg. He spoke to me about the problems of early commitment in Dutch planning, in which politicians commit to a project before design is finalized. Once the political decision has been made, it is easy for actors to extract surplus, because the state or city cannot walk away easily, while a 20% cost overrun is much easier to explain to the public. This problem plagued 2000s investments like HSL Zuid. To deter this, after 2009 the Netherlands passed reforms that attempt to tackle this problem, aiming to defer the formal political decision to later in the process.
This factor seems to correlate with absolute costs, if not with overruns. American planning is extremely politicized; Canadian planning is fairly politicized too, with individual subway projects identifiable as the brainchildren of specific politicians or parties; Southern European and Nordic planning is highly bureaucratized, with design driven by the civil service and politicians making yes or no decisions late in the process.
Sweden: changes in rules
According to a senior planner at Nya Tunnelbanan, the project has run over from 22.506 billion kronor in 2013 to 31.813 today, both in 2016 price levels; in US dollars, this is $2.551b/19.6 km to $3.606b/19.6 km, all underground. The reasons for the escalation come largely from tighter regulations as well as litigation:
- Safety requirements have been tightened midway through the project, requiring a service tunnel in addition to the two track tunnels, raising excavation volume almost 50%
- An environmental court ruling slowed down excavation further
- Consensus with stakeholders took longer than expected
- Excavated rock was reclassified midway through the project from useful building material to waste that must be disposed of
Focusing on underestimation is not really germane to what’s happened in Stockholm. The problem isn’t that early 2010s engineers failed to anticipate regulations that were not in force at the time. It’s that regulations were changed later. The rock removal process today actually increases greenhouse gas emissions, just because of the need to freight it away, let alone the systemwide effects on climate of making it harder to build subways.
California: scope creep and change orders
California High-Speed Rail is such a big project that its cost overruns, in multiple stages, were amply discussed in the media. The original announcements in the early 2010s, for example here, were largely about scope creep. At-grade segments turned into viaducts; above-ground segments, particularly in the Bay Area, were turned into tunnels. The reasons were mostly about agency turf battles.
Only in one case was the problem more about underestimation than overrun: the Central Valley segment had originally been planned to follow railroad rights-of-way, but had to be redesigned to have more viaducts and swerve around unserved small towns. This was bad planning, at two points: first, the original designs assumed trains could go at 350 km/h through unserved towns, which they don’t anywhere; and second, once the redesign happened, it was so rushed that land acquisition was time-consuming and acrimonious. Even then, much of the overdesign as identified by a Deutsche Bahn postmortem could have been prevented.
The second stage is more recent: the Central Valley construction contracts have long busted their budgets due to change orders. Change orders are a common problem in California, and in this case, it involved not only the change order king Tutor-Perini, but also the usually reasonable Dragados. The situation here must be ascribed to overrun rather than underestimation: a transparent process for handling changes, based on itemized costs, is an emerging best practice, known since the early 2000s to people who cared to know, and more recently seen in the economics literature for general infrastructure. That California failed to follow this practice – which, again, was available already in the late 2000s – is the source of malpractice. The original bids could have held if the process were better.
Absolute costs and cost overruns
Cost overruns are not the same as absolute costs. They are not even obviously correlated: witness the way the US eliminated most overruns on surface light rail projects in the 1990s and 2000s, to the point that projects with large overruns like the Green Line Extension are exceptional, while absolute costs have skyrocketed. But if we understand the problem to be about cost overruns from an ambitious but achievable budget rather than about underestimating a final cost that could not be improved on, then the study of the two topics is inherently intertwined.
Problems that recur in postmortems of cost overruns are not just about estimation. They’re about building better and cheaper. A bureaucratized planning process in which politicians retain the right to make yes-or-no decisions on complete design reduces cost overruns by reducing leakage and surplus extraction; the overruns such a process prevents are preventable extra costs, rather than higher initial estimates. The same is true of avoiding overbuilding, of not introducing extraneous regulations, of treating environmental questions as systemic and quantitative rather than as local under a do-no-harm principle. Even the question of change orders is more transparently about reducing absolute costs in the literature, since the overruns prevented tend to be seen in higher risk to the contractor leading to higher profit margin demands.
The upshot is that this makes the study of absolute costs easier, because we can reuse some of the literature for the related problem of cost overruns. But conceptually, it means that agencies need to be more proactive and treat early budgets as standards to be adhered to, rather than just blow up the budgets preemptively so that it’s easier to stick to them.
The Invention of Bad Railroad Timetables
The rail advocate Shaul Picker has uploaded a fascinating potpourri of studies regarding commuter rail operations. Among them, two deserve highlight, because they cover the invention of bad timetable practices in New York, and, unfortunately, not only think those practices are good, but also view their goodness as self-evident. They are both by Donald Eisele, who was working for the New York Central and implemented this system on the lines that are now Metro-North, first introducing the concept to the literature in 1968, and then in 1978 asserting, on flimsy evidence, that it worked. Having implemented it in 1964 based on a similar implementation a few years earlier in the Bay Area, Eisele must be viewed as one of the people most responsible for the poor quality of American mainline service, and his idea of zone theory or zonal operations must be discarded in favor of the S-Bahn takt.
Eisele’s starting point is that commuter rail service should be exclusively about connecting the suburbs with city center. He contrasts his approach with urban transit, which is about service from everywhere to everywhere; trips short of Manhattan were 20% of single-trip ticket revenue for New York Central suburban operations and 5% of multi-ride pass revenue, and the railroad wanted to eliminate this traffic and focus on suburb-to-city commuters. From this inauspicious starting point, he implemented a timetable in which suburban stations are grouped into zones of a few contiguous stations each, typically 2-4 stations. At rush hour, a train only stops within one zone, and then expresses to city center, which in the original case means Grand Central.
The idea behind zone theory is that, since all that matters is a rapid connection to city center, trains should make as few stops as possible. Instead of trying to run frequently, it’s sufficient to run every 20 or 30 minutes, and then once a train fills with seats it should run express. This is accompanied by a view that longer-haul commuters are more important because they pay higher fares, and therefore their trips should not be slowed by the addition of stops closer in.
It’s important to note that what zone theory replaced was not an S-Bahn-style schedule in which all trains make all stops, and if there’s more demand in the inner area than the outer area then some trains should short-turn at a major station in the middle. American railroads had accumulated a cruft of timetables; Eisele goes over how haphazard the traditional schedules were, with short but irregular rush-hour intervals as some trains skipped some stations, never in any systematic way.
The first paper goes over various implementation details. For example, ideally a major station should be the innermost station within its zone, to guarantee passengers there a nonstop trip to city center. Moreover, considerable attention goes to fare collection: fares are realigned away from a purely distance-based system to one in which all stations in a zone have the same fare to city center, simplifying the conductors’ job. The followup paper speaks of the success of this realignment in reducing fare collection mistakes.
The failure of zone theory
We can see today that zone theory is a complete failure. Trains do not meaningfully serve anyone except 9-to-5 suburban commuters to the city, a class that is steadily shrinking due to job sprawl and a change in middle-class working hours. Ridership is horrendous: all three New York commuter railroads combined have less ridership than the Munich S-Bahn, a single-trunk, seven-branch system in a metropolitan area of 3 million. Metro-North would brag about having an 80% market share among rush hour commuters from its suburban shed to Manhattan, but that only amounts to about 90 million annual riders. In contrast, the modal split of rail at major suburban job centers, even ones that are adjacent to the train station like White Plains and Stamford, is single-digit percent – and Metro-North is the least bad of New York’s three railroads in this category.
Even on the original idea of providing fast service from the suburbs to city center, zone theory is a failure. The timetables are not robust to small disturbances, and once the line gets busy enough, the schedules have to be padded considerably. I do not have precise present-day speed zones for Metro-North, but I do have them for the LIRR courtesy of Patrick O’Hara, and LIRR Main Line service is padded 30% over the technical travel time of present-day equipment on present-day tracks. A textbook I have recently read about scheduling best practices cites a range of different padding factors, all single-digit percent; Switzerland uses 7%, on a complex, interlined network where reliability matters above all other concerns. With 30% padding, the LIRR’s nonstop trains between Ronkonkoma and Penn Station, a distance of 80 km, take about as long as local trains would with 7% padding.
Eisele is right in the papers when he complains about the institutional inertia leading to haphazard schedules. But his solution was destructive, especially in contrast with contemporary advances in scheduling in Europe, which implemented the all-day clockface schedule, starting with Spoorslag ’70 and then the Munich S-Bahn takt in 1972.
Zone theory and reliability
The first paper claims as self-evident that zonal timetables are reliable. The argument offered is that if there is a short delay, it only affects trains within that zone, and thus only affects the stations within the zone and does not propagate further. There is no attempt at modeling this, just claims based on common sense – and transport is a field where intuition often fails and scientific analysis is required.
The problem is that zone theory does not actually make trains in different zones independent of one another. The second paper has a sample timetable on PDF-p. 4 for the evening rush hour, and this can also be reversed for the morning. In the morning, trains from outer zones arrive in city center just after trains from inner zones; in the afternoon, trains serving outer zone stations depart city center first, always with a gap of just a few minutes between successive trains. In the morning, a delay in a suburban zone means that the trains in the zones behind it are delayed as well, because otherwise they would clash and arrive city center at literally the same minute, which is impossible.
This isn’t purely an artifact of short headways between running trains. Subway systems routinely have to deal with this issue. The key is that on a subway system, trains do not have much of their own identity; if a train is delayed, the next train can perfectly substitute for it, and cascading delays just mean that trains run slightly slower and (because the equipment pool is fixed) are slightly more crowded. The principle that individual suburban stations should only be served every 20-30 minutes means no such substitution is possible. S-Bahn trains are not as interchangeable as subway trains, which is why they cannot run as frequently, but they still manage to run every 2-3 minutes with 7% padding, even if they can’t reach the limit values of a train very roughly 1.5 minutes achieved by some big city subways.
Eisele did not think this through and therefore made an assertion based on intuition that failed: reliability did not improve, and with long-term deterioration of speed and lack of reduction in operating expenses, the express timetables at this point are slower than an all-stops S-Bahn would be.
Consultants and Railroaders Turn New Haven Line Investment Into Shelf Art
The state of Connecticut announced that a new report concerning investment in the New Haven Line is out. The report is damning to most involved, chief of all the Connecticut Department of Transportation for having such poor maintenance practices and high construction costs, and secondarily consultant AECOM for not finding more efficient construction methods and operating patterns, even though many readily exist in Europe.
What started out as an ambitious 30-30-30 proposal to reduce the New York-New Haven trip time to an hour, which is feasible without construction outside the right-of-way, turned into an $8-10 billion proposal to reduce trip times from today’s 2 hours by 25 minutes by 2035. This is shelf art: the costs are high enough and the benefits low enough that it’s unlikely the report will lead to any actionable improvement, and will thus adorn the shelves of CTDOT, AECOM, and the governor’s office. It goes without saying that people should be losing their jobs over this, especially CTDOT managers, who have a track record of ignorance and incuriosity. Instead of a consultant-driven process with few in-house planners, who aren’t even good at their jobs, CTDOT should staff up in-house, hiring people with a track record of success, which does not exist in the United States and thus requires reaching out to European, Japanese, and Korean agencies.
Maintenance costs and the state of good repair racket
I have a video I uploaded just before the report came out, explaining why the state of good repair (SOGR) concept has, since the late 1990s, been a racket permitting agencies to spend vast sums of money with nothing to show for it. The report inadvertently confirms this. The New Haven Line is four-track, but since the late 1990s it has never had all four tracks in service at the same time, as maintenance is done during the daytime with flagging rules slowing down the trains. Despite decades of work, the backlog does not shrink, and the slow zones are never removed, only replaced (see PDF-p. 7 of the report). The report in fact states (PDF-p. 8),
To accommodate regular maintenance as well as state-of-good-repair and normal replacement improvements, much of the four-track NHL typically operates with only three tracks.
Moreover, on PDF-p. 26, the overall renewal costs are stated as $700-900 million a year in the 2017-21 period. This includes rolling stock replacement, but the share of that is small, as it only includes 66 new M8 cars, a less than second-order item. It also includes track upgrades for CTRail, a program to run trains up to Hartford and Springfield, but those tracks preexist and renewal costs there are not too high. In effect, CTDOT is spending around $700 million annually on a system that, within the state, includes 385 single-track-km for Metro-North service and another 288 single-track-km on lines owned by Amtrak.
This is an insane renewal cost. In Germany, the Hanover-Würzburg NBS cost 640 million euros to do 30-year track renewal on, over a segment of 532 single-track-km – and the line is overall about 30% in tunnel. This includes new rails, concrete ties, and switches. The entire work is a 4-year project done in a few tranches of a few months each to limit the slowdowns, which are around 40 minutes, punctuated by periods of full service. In other words, CTDOT is likely spending more annually per track-km on a never-ending renewal program than DB is on a one-time program to be done once per generation.
A competent CTDOT would self-abnegate and become German (or Japanese, Spanish, French, Italian, etc.). It could for a few hundred million dollars renew the entirety of the New Haven Line and its branches, with track geometry machines setting the tracks to be fully superelevated and setting the ballast grade so as to improve drainage. With turnout replacement, all speed limits not coming from right-of-way geometry could be lifted, with the possible exception of some light limits on the movable bridges. With a rebuild of the Grand Central ladder tracks and turnouts for perhaps $250,000 per switch (see e.g. Neustadt switches), trains could do New York-New Haven in about 1:03 making Amtrak stops and 1:27 making all present-day local stops from Stamford east.
The incompetence of CTDOT and its consultants is not limited to capital planning. Operations are lacking as well. The best industry practice, coming from Switzerland, is to integrate the timetable with infrastructure and rolling stock planning. This is not done in this case.
On the contrary: the report recommends buying expensive dual-mode diesel locomotives for through-service from the unelectrified branches instead of electrifying them, which could be done for maybe $150 million (the Danbury Branch was once electrified and still has masts, but no wires). The lifecycle costs of electric trains are half those of diesel trains, and this is especially important when there is a long electrified trunk line with branches coming out of it. Dual-mode locomotives are a pantomime of low electrification operating costs, since they have high acquisition costs and poor performance even in electric mode as they are not multiple-units. Without electrification, the best long-term recommendation is to shut down service on these two branches, in light of high maintenance and operating costs.
The choice of coaches is equally bad. The report looks at bilevels, which are a bad idea in general, but then adds to the badness by proposing expensive catenary modifications (PDF-p. 35). In fact, bilevel European trains exist that clear the lowest bridge, such as the KISS, and those are legal on American tracks now, even if Metro-North is unaware.
The schedule pattern is erratic as well. Penn Station Access will soon permit service to both Grand Central and Penn Station. And yet, there is no attempt to have a clean schedule to both. There is no thought given to timed transfers at New Rochelle, connecting local and express trains going east with trains to Grand Central and Penn Station going west, in whichever cross-platform pattern is preferred.
The express patterns proposed are especially bad. The proposal for through-running to Philadelphia and Harrisburg (“NYX”) is neat, but it’s so poorly integrated with everything else it might as well not exist. Schedules are quoted in trains per day, for the NYX option and the GCX one to Grand Central, and in neither case do they run as frequently as hourly (PDF-p. 26). There is no specific schedule to the minute that the interested passenger may look at, nor any attempt at an off-peak clockface pattern.
Throw it in the trash
The desired rail investment plan for Connecticut, setting aside high-speed rail, is full electrification, plus track renewal to permit the elimination of non-geometric speed limits. It should cost around $1 billion one-time; the movable bridge replacements should be postponed as they are nice to have but not necessary, their proposed budgets are excessive, and some of their engineering depends on whether high-speed rail is built. The works on the New Haven Line are doable in a year or not much more – the four-year timeline on Hanover-Würzburg is intended to space out the flagging delays, but the existing New Haven Line is already on a permanent flagging delay. The trains should be entirely EMUs, initially the existing and under-order M8 fleet, and eventually new lightweight single-level trains. The schedule should have very few patterns, similar to today’s off-peak local and express trains with some of one (or both) pattern diverting to Penn Station; the express commuter trains should take around 1:30 and intercity trains perhaps 1:05. This is a straightforward project.
Instead, AECOM produced a proposal that costs 10 times as much, takes 10 times as long, and produces half the time savings. Throw it in the trash. It is bad, and the retired and working agency executives who are responsible for all of the underlying operating and capital assumptions should be dismissed for incompetence. The people who worked on the report and their sources who misinformed them should be ashamed for producing such a shoddy plan. Even mid-level planners in much of Europe could design a far better project, leaving the most experienced and senior engineers for truly difficult projects such as high-speed rail.
