Providence Should Use In-Motion Charging for Buses

The future of bus transit is in-motion charging. This technology, increasingly common in Central Europe, is a hybrid of the trolleybus and the battery-electric bus (BEB), offering significant off-wire range with no need for centralized recharge facilities. Moreover, the range of batteries is improving over time and so is the recharge rate; in the limit, a pure BEB system may work, but in the present and near future it is not yet reliable in cold weather and requires diesel or oil heaters when the temperature is below freezing.

My original post on IMC technology speaks largely of New York and Boston, but Providence is an excellent place for implementing this technology as well, at least as good as Boston and far better than New York. As Rhode Island is thinking of how to invest in urban transit, it should take this technology into consideration, in addition to proposals for light rail along its busiest route (the Rapid, formerly the 99 and 11 buses) or a diesel BRT.

Transit Forward RI 2040

The guiding program, adopted in 2020, is called Transit Forward, and aims for a statewide plan including regional connections as well as the core of a solid mass transit network in Providence. The Rapid route is to be turned to light rail, perhaps, and multiple other core routes are to be upgraded to BRT standards (including the Rapid if light rail is rejected). This can be viewed here or here. Here is the metropolitan bus map:

Proposed metropolitan bus and light rail map for Providence; an N in front of a number means it’s a new route – it doesn’t denote night buses as in other cities

Observe that multiple trunks are designed to have very high all-day frequency. Already today, service on Broadway and Westminster from Downcity to Olneyville interlines to a bus every 7.5 minutes; the proposal is to boost this to a bus every 7.5 minutes on Westminster and also one every 5 on Broadway. Past Olneyville, the buses branch at lower frequency. South Main is to have a core trunk route every 10 minutes and also a less frequent regional bus. The Angell/Waterman one-way pair is to have three routes running every 20 minutes, two every 30, and two less frequent express buses; closer in, this one-way pair shares the bus tunnel between Downcity and College Hill with routes running on Hope, labeled N117 in the plan.

On net, this is a massive expansion of bus frequency available to people in and around Providence. Were it available when I lived there, I would have an easier time traveling to Pawtucket, East Providence, and other such locations, often for gaming purposes; with the network as it is (or as it was in 2012), I would walk 6 km from my home in Fox Point to a gaming store in Pawtucket and it would still be faster than waiting 40 minutes for the bus in the evening.

IMC and branching

IMC as a technology permits buses to run about 10 km off-wire; the current frontier of the technology is that a minimum of 20-30% of the route needs to be wired. UITP presents it as an advantage in that the wiring cost is only 20-30% of that of a traditional trolleybus, but in fact the wiring cost is much lower, because the trunks can be wired while the branches are left unwired.

This advantage is hard to realize in a city like Chicago or Toronto, with a relentlessly gridded bus network and little branching. Both cities rely on rapid transit for downtown access, and have a bus grid layered on top of their radial metro systems to provide everywhere-to-everywhere connectivity and feed the trains. In such an environment, IMC saves 70-80% of the cost of a trolleybus, minus the additional cost of procuring a bus with a backup battery. This may sound like a lot, but trolleybus expansion is rare globally, so reducing the cost by a factor of 4 does not necessarily turn it into an attractive investment.

But in Providence, there is no grid. About 4 km of wire in each direction, from Downcity to past Henderson Bridge, are enough to electrify nearly the entire bus network connecting the city with East Providence. Another 3 km along South Main and I-195 complete electrification to the east. The N117 may need a short stub on Thayer in addition to the bus tunnel; Broadway and Westminster, totally around 6 km, should be enough to electrify buses to and beyond Olneyville; the core of Broad is planned to carry the N12 and R, both at high frequency, and is therefore a prime target for wiring as well; Charles should be enough to wire most of the buses going due north or northwest.

This way, a core trolleybus network with maybe 30 km of wire in each direction can electrify most of the bus network in Providence, without having to deal with the teething problems of BEBs.

The issue of legibility

One minor benefit of wire in Providence is that it helps casual riders make sense of the public transportation network. A big disadvantage of bus networks over rail is their poor legibility: the map has too many routes and a user is expected to know them all over an area, and there is no indication on the street as to where the buses go. Marked bus lanes help solve the latter problem, as does wire.

Trolleybuses are not streetcars. Their ride quality is that of a bus – usually better, occasionally worse, depending on who I ask. Their network structure is usually like the core of an urban bus network, and not like that of a modern light rail network, which a casual user can get at a glance. The presence of wire makes the system easier to see on the ground, helping improve legibility.

This is especially important in cities without grid networks – precisely the environments in which on purely technical issues IMC is already strongest. In Vancouver, the buses are largely gridded, and so it is generally clear where they go: they run on major streets like Broadway, King Edward, 41st, Arbutus, and MacDonald. But in Providence, it’s not always clear, especially in the seams between two networks. Broadway has a few choices of street connections toward Kennedy Plaza – do buses go on Sabin? Or Fountain? Or Empire to Washington? Westminster has no clear connection – do buses turn left or right on Franklin/Dave Gavitt Way? Wire helps make it clear for the confused passenger who doesn’t live in town, or who lives on the East Side and isn’t familiar with the Federal Hill street network.

This can be better than light rail

RIPTA is interested in making its highest-intensity route, now the R and in the future the N12, into a light rail line. I get where it’s coming from, but I have some worries. Providence development is frustratingly almost linear, but not quite; the train station is in a street loop off Main, and on the map above, the N12 veers off the straight path to connect to it. I don’t know what the optimal way is of serving such a destination, and it’s likely the answer will change over time based on changes in the technology and in other connections.

IMC can be good precisely for this. If the route is partly wired, then small deviations based on changes in the plan are viable, albeit at the cost of legibility. The same goes for uncertainty over which routes connect to which: the R today interlines the old 99 on North Main to Pawtucket and the old 11 on Broad to South Providence, but the plan is to instead connect South Providence to Downcity via the Jewelry District using the N8, and instead have the N12 primary route continue southwest to Warwick via Elmwood and Reservoir. Such changes require a commitment to mode: swaps are fine as long as both routes use the same mode – if they’re both light rail then it is viable and the same is true if they’re both buses, but not if one is rail and the other is bus. IMC downgrades both to a bus, but in a way that permits higher ride quality to some extent and lower emissions at very low costs.

EU Reaches Deal for Eastern European Infrastructure Investment

EU Commission President Ursula von der Leyen announced this morning that the EU will proceed with a coordinated investment plan for Ukraine, whose EU membership is a foregone conclusion at this point, as well as for surrounding EU member states. This will include a cohesion fund for both war reconstruction and long-term investment, which will have a component marked for Belarus’s incorporation into the Union as well subject to the replacement of its current regime with a democratic government.

To handle the infrastructure component of the plan, an EU-wide rail agency, to be branded Eurail, will take over the TEN-T plan and extend it toward Ukraine. Sources close to all four major pro-European parties in the EU Parliament confirm that the current situation calls for a European solution, focusing on international connections both internally to the established member states and externally to newer members.

The office of French President Emmanuel Macron says that just as SNCF has built modern France around the TGV, so will Eurail build modern Europe around the TEN-T network, with Paris acting as the center of a continental-scale high-speed rail network. An anonymous source close to the president spoke more candidly, saying that Brussels will soon be the political capital of an ever closer economic and now infrastructural union, but Paris will be its economic capital, just as the largest city and financial center in the United States is not Washington but New York and that of Canada is not Ottawa but Toronto.

In Eastern Europe, the plan is to construct what German planners have affectionately called the Europatakt. High-speed rail lines, running at top speeds ranging between 200 and 320 km/h, are to connect the region as far east as Donetsk and as far northeast as Tallinn, providing international as well as domestic connections. Regional trains at smaller scale will be upgraded, and under the Europatakt they will be designed to connect to one another as well as to long-distance trains at regular intervals.

For example, the main east-west corridor is to connect Berlin with Kyiv via Poznań, Łódź, Warsaw, Lublin, Lutsk, and Zhytomyr. Berlin-Warsaw trips are expected to take 2.5 hours and Warsaw-Kyiv trips 3.5 hours, arranged so that trains on the main axis will serve Warsaw in both directions on the hour every hour, timing a connection with trains from Warsaw to Kaunas, Riga, Tallinn, and Helsinki and with domestic intercity and regional trains with Poland. In Ukraine, too, a connection will be set up in Poltava, 1.5 hours east of Kyiv, every hour on the hour as in Warsaw, permitting passengers to interchange between Kyiv, Kharkiv, Dnipro, and Donetsk.

Overall, the network through Poland, Ukraine, and the Baltic states, including onward connections to Berlin, Czechia, Bucharest, and Helsinki, is expected to be 6,000 km long, giving these countries comparable networks to those of France and Spain. The expected cost of the program is 150 billion euros plus another 50 billion euros for connections.

How to Spend Money on Public Transport Better

After four posts about the poor state of political transit advocacy in the United States, here’s how I think it’s possible to do better. Compare what I’m proposing to posts about the Green Line Extension in metro Boston, free public transport proposals, federal aid to operations, and a bad Green New Deal proposal by Yonah Freemark.

If you’re thinking how to spend outside (for example, federal) money on local public transportation, the first thing on your mind should be how to spend for the long term. Capital spending that reduces long-term operating costs is one way to do it. Funding ongoing operating deficits is not, because it leads to local waste. Here are what I think some good guidelines to do it right are.

Working without consensus

Any large cash infusion now should work with the assumption that it’s a political megaproject and a one-time thing; it may be followed by other one-time projects, but these should not be assumed. High-speed rail in France, for example, is not funded out of a permanent slush fund: every line has to be separately evaluated, and the state usually says yes because these projects are popular and have good ROI, but the ultimate yes-no decision is given to elected politicians.

It leads to a dynamic in which it’s useful to invest in the ability to carry large projects on a permanent basis, but not pre-commit to them. So every agency should have access to public expertise, with permanent hires for engineers and designers who can if there’s local, state, or federal money build something. This public expertise can be in-house if it’s a large agency; smaller ones should be able to tap into the large ones as consultants. In France, RATP has 2,000 in-house engineers, and it and SNCF have the ability to build large public transport projects on their own, while other agencies serving provincial cities use RATP as a consultant.

It’s especially important to retain such planning capacity within the federal government. A national intercity rail plan should not require the use of outside consultants, and the federal government should have the ability to act as consultant to small cities. This entails a large permanent civil service, chosen on the basis of expertise (and the early permanent hires are likely to have foreign rather than domestic experience) and not politics, and yet the cost of such a planning department is around 2 orders of magnitude less than current subsidies to transit operations in the United States. Work smart, not hard.

However, investing in the ability to build does not mean pre-committing to build with a permanent fund. Nor does it mean a commitment to subsidizing consumption (such as ongoing operating costs) rather than investment.

Funding production, not consumption

It is inappropriate to use external infusions of cash for operations and, even worse, maintenance. When maintenance is funded externally, local agencies react by deferring maintenance and then crying poverty whenever money becomes available. Amtrak fired David Gunn when the Bush administration pressured it to defer maintenance in order to look profitable for privatization and replaced him with the more pliable Joe Boardman, and then when the Obama stimulus came around Boardman demanded billions of dollars for state of good repair that should have built a high-speed rail program instead.

This is why American activists propose permanent programs – but those get wasted fast, due to surplus extraction. A better path forward is to be clear about what will and will not be funded, and putting state of good repair programs in the not-funded basket; the Bipartisan Infrastructure Framework’s negotiations were right to defund the public transit SOGR bucket while keeping the expansion bucket.

Moreover, all funding should be tied to using the money prudently – hence the production, not consumption part. This can be capital funding, with the following priorities, in no particular order:

  • Capital funding that reduces long-term operating costs, for example railway electrification and the installation of overhead wires (“in-motion charging“) on bus trunks.
  • Targeted investments that improve the transit experience. Bus shelter is extremely cost-effective on this point and a federal program to fund it at a level of around $15,000/stop (not more – it’s easy to make local demands that drive it up to $50,000) would have otherworldly social rates of return. Washington bureaucrats are loath to be this explicit about what to do – they try to speak in circumlocutions, saying “standards for bus stops” instead of just funding shelter, or “transit asset management” instead of just committing to not playing the SOGR game.
  • Accessibility upgrades. This require close federal control to eliminate local waste, because much of the money would be going to New York, which has a long-term problem of siphoning accessibility money to other priorities like adding station access points or repairing stations, and has a uniquely incompetent local environment when it comes to construction costs.
  • Planning aid for improving bus-rail interface; these two modes are often not planned together in American cities, and commuter rail is not planned in conjunction with other modes. San Jose, for example, has a proposal for large expansion of bus service, part of which is parallel to Caltrain; the local agency, VTA, owns one third of Caltrain and could expand rail service within the county and integrate it with bus service better, but does not do so.
  • Rail automation, to reduce long-term operating costs. Bus automation could go in this bucket too but is at this point too speculative; save it for one or two stimuli in the future.

Avoiding local extraction

Local government has very little democratic legitimacy. It’s based on informal power arrangements, in which direct elections play little role; partisan elections are rare and instead primaries reign with severe democratic deficits (for example, it’s hard to form any kind of base for opposition to challenge a sitting New York mayor or governor). Without national ideology to guide it, it is the domain of cranks and people with the time and leisure to attend community meetings on weekdays at 3 pm. Local community takes its illegitimate power and thieves what others create, whether it is the market or the state.

Recognizing this pattern means that federal funding should not under any circumstances coddle local arrangements. If, for example, California cannot spend money cost-effectively because it is constrained by referendum, federal funding can be used to bypass this system, but never work under its rules. If the local business community is traumatized by cut-and-cover construction in the distant past, the feds should insist that subway money that they give will be used for cut-and-cover instead of mined stations.

The typical surplus extraction pattern concerns car dominance. State DOTs are in effect highway departments; transit planning is siloed, usually at separate agencies. They use their power to demand the diversion of transit money to roads. For example, in Tampa, a plan to increase bus service led to a DOT demand to pave the routes with concrete lanes at transit agency expense (with federal or state transit funding). The list of BRT projects that were just highway widenings is regrettably too long. The feds should actively demand to keep transit funding for transit, and not roads, social services, policing, or other priorities.

In particular, the feds should give money for some bus improvements, but demand that agencies prioritize the bus over the car. No bus lanes? No signal priority? No money. Similarly, they should demand they engage in internal efficiency measures like stop consolidation and all-door boarding with proof of payment ticket collection, which a larger and more expert FTA can give technical assistance for.

It may also be prudent to give transitional resources, up to a certain point. Funding private-sector retraining for workers displaced by automation is good, and in some limited cases public-sector retraining, as long as it doesn’t turn into workfare (there is no way for the subway in New York to absorb redundant conductors or surplus maintenance staff). If moderate amounts of capital funding are required for bus improvements, such as traffic signal upgrades to have active control and conditional TSP, then they are good investments as well.

Conclusion

Funding public transportation is useful, provided there is enough of a connection between the source of funds and the management thereof that the money is not wasted. A larger and more technocratic federal government is an ideal organ for this, with enough planning power to propose bus network redesigns, rail planning, integrated fare systems, and intermodal coordination. It can and should have technical priorities – shelter is far and away the lowest-hanging fruit for American bus systems – and state them clearly rather than hiding behind bureaucratic phrases (again, “transit asset management” is a real phrase).

It’s fundamentally an investment rather than consumption. And as with all investments, it’s important to ensure one invests in the right thing and the right people. A local transit agency with a track record of successful projects, short lead times from planning to completion, technical orientation, and the ability to say no to highway departments and other organs that extract surplus is a good investment. One that instead genuflects before antisocial groups that launch nuisance lawsuits is not so good an investment, and funding for such an agency should be contingent on improvement in governance of the kind that will make local notables angry.

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.

No Federal Aid to Transit Operations, Please

This is the third in a series of four posts about the poor state of political transit advocacy in the United States, following posts about the Green Line Extension in metro Boston and free public transport proposals, to be followed by an Urban Institute report by Yonah Freemark.

In the United States, political transit activists in the last few years have set their eyes on direct federal aid for operating subsidies for public transport. Traditionally, this has not been allowed: federal aid goes to capital planning (including long-term maintenance), and only a small amount of money goes to operations, all in peripheral bus systems. Urban transit agencies had to operate out of fares and local and state money. Demands for federal aid grew during corona, where emergency aid to operations led to demands for permanent subsidies, and have accelerated more recently as corona recovery has flagged (New York’s subway ridership is only around 60% of pre-corona levels). But said demands remain a bad idea in the short and long terms.

In the early 20th century, when public transport was expected to support itself out of fares, operating costs grew with wages, but were tempered by improvements in efficiency. New York City Transit opened with ticket-takers at every subway entrances and a conductor for every two cars; within a generation this system was replaced with automatic turnstiles and one conductor per train. Kyle Kirschling’s thesis has good data on this, finding that by the 1930s, the system grew to about 16,000 annual car-miles (=26,000 car-km) per employee.

And then it has stagnated. Further increases in labor efficiency have not happened. Most American systems have eliminated conductors, often through a multi-decade process of attrition rather than letting redundant workers go, but New York retains them. The network today actually has somewhat less service per employee than in the 1930s, 14,000 car-miles as of 2010, because fixed costs are spread across a slightly smaller system. Compare this with JICA’s report for Mumbai Metro comparing Japanese cities: Tokyo Metro has 283,871,000 car-km (PDF-p. 254) on 8,474 employees (PDF-p. 9), which is 33,500/employee, and that’s without any automation and with only partially conductor-less operations; Yokohama gets 40,000.

Moreover, the timeline in the US matches the onset of subsidies, to some extent: state and local subsidies relieved efficiency pressure. In Canada, TTC saw this and lobbied against subsidies for its own operations in the 1960s, on the grounds that without a breakeven mandate, the unions would capture all surplus; it took until the 1970s for it to finally receive any operating subsidies.

Federal subsidies make all of this worse. They are other people’s money (OPM), so local agencies are likely to maximize them at the expense of good service; this is already what they do with capital money, lading projects with local demands for betterments figuring that if everyone else hogs the trough then they should as well.

Then there is the issue of wages. Seniority systems in American unionized labor create labor shortages even when pay is high, because of how they interact with scheduling and tiered wage structures. Bus drivers in Boston earn around $80,000 a year, a pay that German bus and train drivers can only dream of, but starting drivers are in probational status and have a lower wage (they are not even given full-time work until they put in a long period of part-time work). Moreover, because drivers pick their shifts in seniority order, drivers for about the first 10 years are stuck with the worst shifts: split shifts, graveyard shifts at inconsistent intervals, different garages to report to. New York manages to find enough bus drivers to fill its ranks but only by paying around $85,000 a year; other American cities, paying somewhat less, are seeing thousands of missed runs over the year because they can’t find drivers.

And outside aid does nothing to fix that. Quite to the contrary, it helps paper over these problems and perpetuates the labor gerontocracy. New York City Transit has learned to react to every crisis by demanding a new source of income; there is not enough political appetite for transparent taxation, so the city and state find ever more opaque sources of funds, avoiding political controversy over wanton inefficiency but creating more distortion than a broad income tax would.

Instead of subsidizing current consumption, a developmental state should subsidize production. Don’t pay money to hire more bus drivers; pay for automating subway systems, for better dispatching, for better planning around intermodal integration. Current American wages, not to mention the unemployment rate, scream “invest in labor-saving technology” and not “expand labor-intensive production.”

Free Public Transport: Why Now of All Times?

This is the second in a series of four posts about the poor state of political transit advocacy in the United States, following a post about the Green Line Extension in metro Boston, to be followed by the topics of operating aid and an Urban Institute report by Yonah Freemark.

There’s a push in various left-wing places to make public transportation free. It comes from various strands of governance, advocacy, and public transport, most of which are peripheral but all together add up to something. The US has been making some pushes recently: Boston made three buses fare-free as a pilot program, and California is proposing a three-month stimulus including free transit for that period and a subsidy for car owners. Germany is likewise subsidizing transport by both car and public transit. It’s economically the wrong choice for today’s economy of low unemployment, elevated inflation, and war, and it’s especially troubling when public transport advocates seize upon it as their main issue, in lieu of long-term investments into production of transit rather than its consumption.

Who’s for free public transit?

Historically, public transit was expected to be profitable, even when it was publicly-run. State-owned railroads predate the modern welfare state, and it was normal for them to not just break even but, in the case of Prussia, return profits to the state in preference to broad-based taxes. This changed as operating costs mounted in the middle of the 20th century and competition with cars reduced patronage. The pattern differs by country, and in some places (namely, rich Asia), urban rail remained breakeven or profitable, but stiff competition bit into ridership even in Japan. The norm in most of the West has been subsidies, usually at the local or regional level.

As subsidies were normalized, some proposed to go ahead and make public transport completely free. In the American civil rights movement, this included Ted Kheel, a backer of free public transit advocates like the activist Charles Komanoff and the academic Mark Delucchi. Reasons for free transit have included social equality (since it acts as a poll tax on commuters) and environmental benefits (since it competes with cars).

Anne Hidalgo has attempted and so far failed to find the money for free public transport in Paris, and other parts of Europe have settled for deep discounts in lieu of going fully fareless: Vienna charges 365€ for an annual pass (Berlin, which breaks even on the U-Bahn as far as I can tell, does so charging 86€/month).

In the United States, free transit has recently become a rallying cry for DSA, where it crowds out any discussion of improvement in the quality of service. Building new rail lines is the domain of wonks and neoliberals; socialists call for making things free, in analogy with their call for free universal health care. Boston has gotten in on the act, with conventional progressive (as opposed to DSA) mayor Michelle Wu campaigning on free buses within the municipality and getting the state-run MBTA to pilot free buses on three routes in low-income neighborhoods.

What’s wrong with free transit?

It costs money.

More precisely, it costs money that could be spent on other things. In Ile-de-France, as of 2018, fare revenues including employer benefits amounted to 4 billion euros, out of a total budget of 10.5 billion. The region can zero out this revenue, but on the same budget it can expand the Métro network by around 20-25 km a year – and the Métro is as far as I can tell profitable, subsidies going to suburban RER tails and buses. For that matter, the heavy subsidies to the suburbs, which pay the same cheap monthly rate as the city, could be replaced with investment in more and better lines.

The experiments with actually-free transit so far are in places with very weak revenues, like Estonia. Some American cities like it in context where public transport is only used by the desperate and no attempt is made at making service attractive to anyone else. Boston is unique in trying it in a context with higher fare revenue – but the buses are rail feeders, so the early pilot piggybacks on this and spends relatively little money in lost revenue, ignoring the long-term costs of breaking the (limited) fare integration between the buses and the subway.

What’s wrong with free transit now?

Free transit as deployed in the California proposal is in effect a stimulus project: the government gives people money in various ways. Germany is doing something similar, in a package including 9€ monthly tickets, a 0.30€ fuel tax cut, and a cut in energy taxes.

In Germany, unemployment right now is 2.9% and core inflation (without food and energy) is 3%. This is a country that spent a decade thinking going over 2% was immoral, and now the party that considers itself the most budget hawkish is cutting fuel taxes, in a time of conflict with an oil and gas exporter and a rise in military spending.

In the United States, unemployment is low as well, and inflation is high, 6.4%. This is not the time for stimulus or investments in consumption. It’s time for investments in production and suppression of consumption. So what gives?

The Green Line Extension

This is what I hope to be the first in a series of four posts about the poor state of political transit advocacy in the United States, to be followed by posts about free transit, operating aid, and an Urban Institute report by Yonah Freemark.

The Green Line Extension in Boston opened on Monday. Or, at least, the Union Square branch did; the main line to Tufts is expected to open in a few months. I rode it with Marco Chitti in the afternoon, a few hours after the formal opening ceremony. It was incomplete, with some access points not yet open, and the station fare barriers not yet functional (ticket receipts are checked by staff). There were many railfans on the platforms taking photos, and we accidentally let the first arriving train go because of a misunderstanding over whether it was in service; at least during the first day, it was not yet intended for a general audience.

Bostonians seem to view the extension as a great success. The media’s tone is celebratory. I no longer remember what local New York media said when Second Avenue Subway opened at the beginning of 2017, but I think it was more sober, more reflective of its high costs (I was getting a lot of followers on Twitter, but I tweeted that I was looking for work in the field around that day and got a lot of boosts over that). Within a year of SAS’s opening, Brian Rosenthal’s article appeared, detailing the mess that led to the line’s $1.7 billion/km cost. And as far as I can tell, there’s no comparable look at GLX in Boston.

This is not for lack of material. The Transit Costs Project began as a case study of how GLX got so expensive – it cost $2.2 billion not including rolling stock for a total length of 7.6 km. For a subway, it’s somewhat above global average. But it’s a light rail line with a short elevated segment and the rest in existing commuter rail trenched rights-of-way.

The line isn’t even especially good for the cost. It’s still incomplete. The fare payment is especially messy. The CharlieCard system used in Boston is a legacy mid-2000s system, which the MBTA wants to replace with something called AFC 2.0 (Charlie being AFC 1.0); it gave the contract to American transit agencies’ favorite military contractor, Cubic, which recently said it’s going to have a multi-year delay because it’s prioritizing New York’s Omny contract, and there’s nothing Massachusetts can do about it. When GLX value-engineered the stations, it was expected AFC 2.0 would be done by now, so there was no need for AFC 1.0-compatible fare barriers. It isn’t, so station staff stand in front of the platform directing passengers to tap their cards to get paper receipts. Going fareless at just this station for a short period is looked down on because it’s in a rich neighborhood and it may be discriminatory.

And as far as I can tell, nobody in Boston is asking “how can we make sure it will never happen again?”. The criticism I see in the media is about gentrification; Union Square has been gentrified for at least 10 years, but local politicians like Ayanna Pressley are using the line as an opportunity to make social criticism and impose even more political restrictions, so that future lines will be even kludgier and more expensive.

The MBTA is not always like this. Small projects do not have a large cost premium in Boston. Commuter rail infill stations, designed in-house, have a cost premium over Berlin in the 1.5x area. But the MBTA lacks in-house capacity to manage larger projects; GLX is beyond its capacity, so the original project was stuck and ballooned to $3 billion, and Governor Charlie Baker restarted it as a special-purpose vehicle, rather like Crossrail, with an externally-hired project manager in John Dalton. This mirrors the other transit megaproject in the region, South Coast Rail, currently clocking around $3.4 billion for 77 km of commuter rail in existing rights-of-way, a cost in line with German greenfield high-speed rail with considerable tunneling. No in-house hires were made, and now it seems that Dalton will be let go to take his experience elsewhere; the next MBTA megaproject will start from zero.

And as far as I can tell, nobody is pointing out this pattern. Baker and his political appointees are certain that their method works, because they are ignorant of global best practices. They are not exposed to ideas outside the US, except maybe in the most globalized parts of Britain and other high-cost English-speaking countries; a European who speaks to them like a typical European does – that is, without any pretension that Americans are better people – will just never get through.

In fact, they are failures. Not Dalton, who made the project better (but who is still unemployable anywhere with low costs; Milan Metro has its own in-house team, thank you very much). But Baker, who led the privatization of the state as budget director in the Weld era 30 years ago, must be viewed as the primary villain. His secretary of transportation for much of this period, Stephanie Pollack, must be viewed in a similar way: she does not believe it is possible to compare different projects, perhaps because the ones she is involved with are deficient. People should point at them and laugh on the street and perhaps yell at them for wasting government money with their failed ideology.

The second villain, after the state capacity destroyer that is Baker, consists of Governor Deval Patrick, who let the project balloon. He did not rebuild state capacity; he instead instructed the MBTA to accept the demands of every community that wanted something – in this case, Somerville and its demand for premium-cost bike paths (“Somerville Community Path”) and oversize stations. Pressley is an heir to this tradition; unless she changes her tune, it will be best for infrastructure if she is ignored, or better yet defeated for reelection.

Right now, I do not see any political group in the Boston area that is interested in making things better. High costs to them are just “it’s our turn to hog the trough.” This has implications for federal funding: the feds should choke funding to the region if it stays like this.

The G Train

The G train is bad. I say this, 16 years after I moved to New York, 11 years after I left, and I know it’s what every New Yorker knows. Tourists walk too slowly, rent is too high for small apartments, and the G train sucks. What I want to highlight in this post is how the subway’s scheduling paradigm is especially bad for the G train and leads to a vicious cycle making the train less frequent and less useful for passengers.

The role of the G train

The G train is the only mainline subway service in New York that does not enter Manhattan; see map here. It connects what are now the region’s two largest non-Manhattan business centers, Long Island City and Downtown Brooklyn, running vaguely parallel to the East River on the Queens and Brooklyn side of it. To the south of Downtown Brooklyn, it has a tail serving the wealthy neighborhoods collectively called South Brooklyn, such as Carroll Gardens and Park Slope.

I’ve criticized the G before for its poor construction. It misses critical transfers, like the other lines built in the IND program in the 1920s-30s. In Queens it misses Queensboro Plaza and the transfer to the N/W trains on the Astoria Line, and in Brooklyn it misses every single non-IND line except the L (and, at a suboptimal location, the R). This already makes it less useful as a circumferential line – such lines live on convenient transfers to radial lines, because direct O&D service is less valuable to secondary destinations than to primary ones.

But what I realized last week, commuting from Long Island City to Downtown Brooklyn, is more delicate. My hotel was near Queensboro Plaza, which the G doesn’t serve, but the station is served by the 7, which connects to the G one stop away at Court Square; Marron’s new office is in Downtown Brooklyn right on top of the Jay Street station, on the IND-built A/C and F trains, which is either a cross-platform connection or a short walk from the G. So for my trip, the connections worked. And yet, I was regularly facing 10-minute waits on the shoulders of rush hour, and on the subway countdown clock I saw a 15-minute gap.

To explain what went so wrong that the G should have such low frequency at 10 in the morning, it’s necessary to explain how New York City Transit decides the frequency of each service during each time of day.

New York City Subway frequency

In New York, the system for deciding the frequency of each subway service at each time of day is based on average peak crowding. This means that for all trains using the service in a given time period, the crowding level at the peak crowding point of the journey is averaged; frequency is adjusted so that off-peak the peak crowding level is 125% of seated capacity, and at rush hour it is based on published standing capacity per car that works out to about 300% of seated capacity depending on car design.

This system is done per numbered or lettered service. Thus, for example, the 2 and 3 trains run on the same track most of the way, but where they diverge, the 2 is considerably busier, and therefore the 2 runs slightly higher frequency (most ridership on the 2 and 3 is on the shared segment, not the tails). As a result, on the shared trunk, there cannot be perfect alternation of 2 and 3 trains; a few times an hour, a 2 train is followed by another 2 train, which means that on the tail, the frequency is uneven. When two 2 trains follow each other with no 3 between them, the leading 2 train is more crowded than the trailing one; this variation is averaged out in the guidelines – it is not the busiest train that sets the frequency guidelines.

These guidelines are not a good way to timetable trains. The above example of how it can create uneven crowding on the 2 is one problem with this system; if instead there were regular alternation of 2 and 3 trains then the 2 would be persistently slightly more crowded than the 3, just as today there is uneven crowding whenever two 2 trains run with no 3 in between, but the frequency on both the shared trunk and the branches would be more regular. This is especially important on more complexly interlined parts of the network, where the current system leads to large programmed gaps between trains occasionally.

The G is not very heavily interlined; the issue there relates to another criticism of the guidelines, which is that they assume travel demand is fixed. If the ridership on a train is independent of frequency, which it is if the headway between trains is very short compared to the trip time (say, if the trains run every 2-3 minutes), then the sole purpose of service is to provide the capacity the passengers need, and so the guidelines make sense as a way of rationing service convenience. However, in reality, the elasticity of ridership with respect to service provision is not zero. Three years ago I did some analysis of New York’s situation and the existing literature on ridership-frequency elasticity, suggesting it is equal to about 0.4. So the low frequency of the G deters ridership, which then appears to justify the low frequency.

But 0.4 < 1. And I believe that there are two reasons why on the G, and on circumferential lines in general, the elasticity of ridership with respect to frequency should be higher.

Trip length

Circumferential lines in general tend to have shorter average trip time. Between two nearby spokes, say between Downtown Brooklyn and Williamsburg, they are the only real option; between two farther away ones, a direct radial may be an alternative.

The G is different from (say) the Ringbahn in that it misses most transfers, but this should not impact this pattern too much. The missed transfers in Downtown Brooklyn weaken the G for short as well as long trips involving a connection there. In contrast, in the middle the G does make the most important transfer, that with the L, and only misses the weaker J/M/Z.

The 0.4 estimate for ridership elasticity with respect to frequency assumes average behavior for trip length. But if trips are shorter, then the impact of frequency is larger. The 0.4 estimate comes out of an estimate of about -0.8 of ridership with respect to generalized trip time, which includes in-vehicle time, walk time, and wait time, the latter two given extra weight to account for transfer penalty. If one of the three components of trip times is shortened, the other two grow in importance.

The role of options

The G is not usually passengers’ only choice for making the trip. They can connect in Manhattan, or, in some cases, go directly via Manhattan, for example taking the N or R from Downtown Brooklyn to Queens (in the opposite direction, they serve separate station so it’s a harder choice, leading to asymmetric demand). Going between Marron and the East Village, Eric Goldwyn could connect to the L via the A/C/F or the G; I never once saw him use the G, only the lines via Manhattan.

I have not seen the impact of different transit paths on demand elasticity in the literature. It is likely that the elasticity in such case must be higher, because it is standard in economics that demand is more elastic for goods sold on a competitive market than by a monopolist.

Note also that it is to the overall system’s benefit to convince passengers to switch from radial lines to the G. The G is less crowded, so such a switch distributes ridership better on the system. And the G starts out much less frequent, so that even on a fixed operating budget, the impact of a service increase on the G on ridership is larger than on an already frequent trunk.

How High-Speed and Regional Rail are Intertwined

The Transit Costs Project will wrap up soon with the report on construction cost differences, and we’re already looking at a report on high-speed rail. This post should be read as some early scoping on how this can be designed for the Northeast Corridor. In particular, integration of planning with regional rail is obligatory due to the extensive track sharing at both ends of the corridor as well as in the middle. This means that the project has to include some vision of what regional rail should look like in Boston, New York, Philadelphia, and Washington. This vision is not a full crayon, but should have different options for different likely investment levels and how they fit into an intercity vision, within the existing budget, which is tens of billions thanks to the Bipartisan Infrastructure Framework.

Boston

In Boston, commuter rail and intercity rail interact via the Providence Line, which is double-track. The Providence Line shares the same trunk line into Boston with the Franklin Line and the Stoughton Line, and eventually with South Coast Rail services.

The good news is that the MBTA is seriously looking at electrifying the trains to a substantial if insufficient extent. The Providence Line is already wired, except for a few siding and yard tracks, and the MBTA is currently planning to complete electrification and purchase EMUs on the main line, and possibly also on the Stoughton Line; South Coast Rail is required to be electrified when it is connected to this system anyway, for environmental reasons. If there is no further electrification, then it signals severe incompetence in Massachusetts but is still workable to a large extent.

Options for scheduling depend on how much further the state invests. The timetables I’ve written in the past (for an aggressive example, see here) assume electrification of everything that needs to be electrified but no North-South Rail Link tunnel. An NSRL timetable requires planning high-speed rail in conjunction with the entirety of the regional rail system; this is true even though intercity trains should terminate on the surface and not use the NSRL tunnel.

Philadelphia

Philadelphia is the easiest case. Trenton-Philadelphia is four-track, and has sufficiently little commuter traffic that the commuter trains can be put on the local tracks permanently. In the presence of high-speed rail, there is no need for express commuter trains – passengers can buy standing tickets on Trenton-Philadelphia, and those are not going to create a capacity crunch because train volumes need to be sized for the larger peak market into New York anyway.

On the Wilmington side, the outer end of the line is only triple-track. But it’s a short segment, largely peripheral to the network – the line is four-track from Philadelphia almost all the way to Wilmington, and beyond Wilmington ridership is very low. Moreover, Wilmington itself is so slow that it may be valuable to bypass it roughly along I-95 anyway.

The railway junctions are a more serious interface. Zoo Interlocking controls everything heading into Philadelphia from points north, and needs some facelifts (mainly, more modern turnouts) speeding up trains of all classes. Thankfully, there is no regional-intercity rail conflict here.

Washington

In some ways, the Washington-Baltimore Penn Line is a lot like the Boston-Providence line. It connects two historic city centers, but one is much larger than the other and so commuter demand is asymmetric. It has a tail behind the secondary city with very low ridership. It runs diesel under catenary, thanks to MARC’s recent choice to deelectrify service (it used to run electric locomotives).

But the Penn Line has significant sections of triple- and quad-track, courtesy of a bad investment plan that adds tracks without any schedule coordination. The quad-track segment can be used to simplify the interface; the triple-track segment, consisting of most of the line’s length, is unfortunately not useful for a symmetric timetable and requires some strategic quad-track overtakes. The Penn Line must be reelectrified, with high-performance EMUs minimizing the speed difference between regional and intercity trains. There are only five stations on the double- and triple-track narrows – BWI, Odenton, Bowie State, Seabrook, New Carrollton – and even figuring differences in average speed, this looks like a trip time difference between 160 km/h regional rail and 360 km/h HSR of about 15 minutes, which is doable with a single overtake.

New York

New York is the real pain point. Unlike in Boston and Washington, it’s difficult to isolate different parts of the commuter rail network from one another. Boston can more or less treat the Worcester, Providence+Stoughton, Fairmount, and Old Colony Lines as four different, non-interacting systems, and then slot Franklin into either Providence or Fairmount, whichever it prefers. New York can, with current and under-construction infrastructure, plausibly separate out some LIRR lines, but this is the part of the system with the least interaction with intercity rail.

Gateway could make things easier, but it would require consciously treating it as total separation between the Northeast Corridor and Morris and Essex systems, which would be a big mismatch in demand. (NEC demand is around twice M&E demand, but intercity trains would be sharing tracks with the NEC commuter trains, not the M&E ones; improving urban commuter rail service reduces this mismatch by loading the trains more within Newark but does not eliminate it.)

It’s so intertwined that the schedules have to be done de novo on both systems – intercity and regional – combined. This isn’t as in Boston and Washington, where the entire timetable can be done to fit one or two overtakes. This isn’t impossible – there are big gains to be had from train speedups all over and there. But it requires cutting-edge systems for timetabling and a lot of infrastructure investment, often in places that were left for later on official plans.

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).
