As late as 1980, the United States had more kilometers of metro lines per capita than all large developed countries but the United Kingdom—thanks in part to large public investments in projects like Washington’s Metro and San Francisco’s BART. In the decades since, both the United States and the United Kingdom have stagnated, falling behind even as other countries, particularly China, but also India and many in Europe and South America, have invested in massive new construction campaigns. Much of the world’s urban areas are rapidly becoming dominated by metro service.
In this post, I exploit data from the newly expanded Transit Explorer database, which now includes all metro lines worldwide plus other fixed-route transit services in many countries. The database has been significantly expanded since I wrote about findings from its last update in January. This geospatial database allows me to investigate when and where transit is being built.
The first trend is unambiguous: Worldwide, metro service availability has expanded exponentially. In 1950, only 24 metropolitan areas in 13 countries globally could boast of a subway, elevated line, or monorail (automated light metros didn’t yet exist). Today, 232 metropolitan areas in 63 countries can make such a claim.
Metro construction has accelerated. The number of kilometers of metro lines in active service has expanded from just over 7,000 in 2000 to more than 23,000 today—a tripling of service even as the global population has grown by only about 30 percent during that time. There are almost 7,000 additional kilometers of metro lines currently under construction globally.
The increase in metro service availability in since 2000 has been driven by Chinese cities, which now host more than 40 percent of world metro kilometers. European cities have been steadily increasing their metro route length since the 1970s, however, and Indian cities have accelerated subway and elevated construction since 2010.
Cities in the United States had a plurality of the world’s metro kilometers until 1960. At that point, cities in the now-European Union accumulated more route kilometers (European cities now have about double the total metro kilometers as those in the United States). Chinese cities passed those in Europe in terms of length in about 2010—and Indian cities are expected to host more metro service than the United States by 2025, given current construction activity.
One major explanation for the United States’ declining rank in terms of metro service availability is the fact that the New York City region—which had the world’s longest metro system until the mid-1980s—now has fewer subway or elevated kilometers than it did in 1940, at its peak.
The New York region now has the 13th longest metro system in the world (including the Subway and PATH)—shorter than systems in nine Chinese cities (not all shown on the following graph), plus London, Moscow, Seoul. By 2025, it will be the 15th longest, passed by Delhi and another Chinese city. Remarkably, Shanghai’s metro system is now twice as long as New York’s Subway—despite the former only opening its doors in 1993. New York City has no serious plans to expand its system, even as virtually every other major metropolitan area is doing so.
The result of the United States’ limited progress in providing metro services to its residents is that the number of metro kilometers per resident in the country is now lower than it was in the 1980s. It had the second-most-plentiful metro service per-capita in the world until that point (after the United Kingdom)—but on this metric it has now been passed by the European Union, as well as China, Japan, Russia, and South Korea, among other countries.
Even when incorporating data on light rail and streetcar lines—which US cities have been more focused on building than metros—transit service availability has declined since the 1970s. Indeed, all of the rail transit construction that’s occurred in the United States since the 1980s has done little more than keep up with population growth.
Up until 2000—perhaps surprisingly given lower transit ridership—the United States had more kilometers of metro and light rail lines per capita than residents of neighboring countries or many large European countries for which the Transit Explorer database has complete information (the database does not yet include light rail or streetcar lines for all countries).
But the United States has lost its position on this metric to France and Spain in the years since. France went from having about half the per-capita urban rail miles as the United States in 2000 to significantly more today. And countries like Italy and the Netherlands have been rapidly expanding their services in recent years.
What’s next for the United States? The federal government’s infrastructure law, passed in 2021, will send hundreds of billions of dollars to cities for new transit projects. So far, though, that hasn’t been enough to spur a massive investment in new transit lines compared to past efforts. Transit agencies in major cities are facing a “fiscal cliff” due to declining ridership that may make it more difficult for them to continue to provide adequate daily service. And construction costs are rising rapidly due to inflation.
Using the data embedded in the Transit Explorer database, I calculated key statistics on how transit investment has changed over time in the United States and a number of other countries. These data point to some intriguing trends, notably a decline in investment stateside combined with significant expansion in countries like Canada, Egypt, France, Israel, and Turkiye (I have not yet assembled data for countries in south and east Asia, where transit expansion is proceeding even more quickly).
Over the past century, transit construction in the US waxed and waned. Overall, the number of kilometers of rail transit systems added reached its apex (at least since the 1920s) in the 1990s, when about 1,000 kilometers of new commuter rail lines were opened. During the first decade of the 2000s, the country added the most heavy rail (subway/metro) and light rail lines, generating more than 500 new kilometers over ten years, a record.
Since 2010, however, rail transit construction has lost steam in the US. The number of kilometers opened declined by about 30 percent between the 2000s and 2010s, and the first few years of the 2020s suggest further decline by 2030. At the current rate, less than 500 new kilometers of rail transit will open by then—the lowest figure since the 1970s.
Nevertheless, among the countries in the Transit Explorer database (meaning, excluding Australia, plus south and east Asian countries), the US now has the most kilometers of metro rail (heavy rail or light metro). As of 2023, it has about 1,350 kilometers in operation, of which about a third are in the New York region.
But the growth rate of active metro lines in the US has been slower than in other countries since 2000, increasing by only about 10 percent in route length (the US population grew by 18 percent over the same period). The length of metro systems more than doubled in Brazil and increased by 45 percent in Spain, by contrast.
And there are about 1,700 kilometers of metro in operation in the European Union’s seven most populous countries (Germany, France, Italy, Spain, Poland, Romania, and the Netherlands), whose collective population is almost identical to that of the United States. Their metro route length has increased by 30 percent overall since 2000—three times as fast as the US. (Those countries’ populations collectively grew by only about 4.5 percent between 2000 and 2021.) It is worth noting that Russia’s urban metro rail systems have also expanded tremendously since 2000, outpacing Spain as of 2022.
We can see similar trends when examining the number of light rail, tramway, or streetcar stations in operation across the countries in the database. Since 1980, US cities have invested heavily in light rail, adding about 1,370 stations nationwide. That’s a lot, but it is less than in those seven EU countries combined (2,100 stations), and even just in France (1,450 stations).
And some countries, like Italy, are planning very large investments in new tramways in the coming year.
Transit expansion plans, of course, vary by metropolitan area. Among regions in the US and Canada, New York has by far the largest number of line kilometers of light or heavy rail, followed by the Bay Area, Mexico City, Washington, DC, Los Angeles, and Toronto.
But New York actually has fewer active heavy rail lines in service than it did in 1950. And neither it nor Chicago has added much light rail or subway service since the turn of the millennium. Neither has any major expansion plans actually funded for completion over the next five years, either.
Los Angeles, Montreal, Seattle, and Toronto, on the other hand, stand out as having the largest transit expansion plans in terms of new route kilometers that are currently under construction or planned, meaning projects are funded and almost ready for construction.
And when controlling for urban area population, New York is arguably an under-performer when it comes to overall transit route length. The New York urban area currently has fewer light or heavy rail kilometers per capita than the Baltimore, Bay Area, Denver, Philadelphia, San Diego, St. Louis, and Washington, DC regions. It goes to show that having the maximum amount of transit route length isn’t necessarily directly correlated with having the most transit ridership; the New York area carries more people on transit than all those regions combined.
But New York, as noted, also stands out for having no light rail or subway projects that are either under construction or funded. This situation contrasts strongly with the Minneapolis and Seattle urban areas, whose rail transit expansion plans are the largest in the US on a per-capita basis.
New York’s limited transit expansion prospects are particularly remarkable when compared to the plans of many other world regions. Cairo, Istanbul, Paris, Riyadh, Tel Aviv, and Toronto each have many light rail or metro lines under construction today—and many more kilometers planned (Paris is likely to soon overtake London and New York in terms of total kilometers of such routes). London, on the other hand, has none.
Different regions are investing in different ways. Among routes that are currently under construction, Casablanca, Copenhagen, Los Angeles, Seattle, Tel Aviv, and Toronto have focused heavily on light rail projects. Cairo, Istanbul, Lagos, Montreal, Paris, and Riyadh are building at least 50 kilometers of metro rail each. And Bogota, Paris, and Rio de Janeiro are building many kilometers of bus rapid transit.
The result of all this expansion is that New York’s once-dominant position as having the world’s longest metro network—a position it claimed from London in the 1910s—has eroded. New York pulled down many of its elevated lines and didn’t do much to expand its Subway network. Meanwhile, London took on the mantle in the 1980s through its expansion with the Docklands Light Railway, and, through systematic, relentless expansion, Moscow took the crown from London in the 2010s. Systems in East Asia are even larger. At the same time, Paris, Cairo, and Istanbul have massive expansion plans with many new lines opening over the next five years.
These conditions overall tell a story of declining US commitment to transit expansion in the context of large growth in other countries around the world. There are some exceptions—Seattle, in particular, has a big investment in new lines planned. But while the world is building out ever more accessible transit systems, the US appears to be falling behind.
Last year, three lines Americans have been waiting on for decades—the Green Line extension in Boston, the Crenshaw Line in Los Angeles, and the Silver Line to Dulles Airport outside Washington—finally opened. Though they took years to be completed, they were greetedenthusiastically by riders and political officials content to bring better service to more people.
Similar reception greeted new rail and bus lines opening in Athens, Cairo, Guadalajara, Helsinki, Paris, and dozens of other cities around the world. And much more is planned for 2023: Finally, Long Island Rail Road service will reach the sub-sub-sub-basement of Grand Central Terminal. Toronto’s Eglinton light rail line will connect the city crosstown. And Honolulu, Gebze, Riyadh, Tel Aviv, and Thessaloniki will get their first metro services.
This year, I leveraged data assembled in the Transit Explorer database to identify which projects opened in 2022, which are planned for opening in 2023, and which will be under construction this year—for a later opening date.

The Transit Explorer database now includes all fixed–guideway urban transit systems (meaning rail and bus rapid transit) across North America, South America, Africa, and nine Western European countries, plus metro systems throughout Europe and in parts of the Middle East. Transit Explorernow includes about 29,200 urban transit stations and about 6,700 urban transit lines (covering 78,000 kilometers). (It also includes some intercity rail systems.) These are the geographies for which I provide details about transit line openings below.
Istanbul’s metro network—spanning continents—is becoming one of the world’s largest.
Bogota is a bus rapid transit haven—but a new metro system is planned.
Overall, 517 kilometers of new fixed-guideway urban transit services opened in 2022 across the countries covered by the Transit Explorer database. Of these, the countries with the largest increases in kilometers were the United States (196 kilometers); Egypt (77 kilometers); Mexico (60 kilometers); France (39 kilometers); and the United Kingdom (34 kilometers).

Planned 2023 openings
Almost 1,100 kilometers of fixed-guideway urban transit is planned to open in 2023 in the parts of the world covered by Transit Explorer. Of these, about half will be in the form of metro rail services. The countries with the largest expansions planned for opening are the United States (242 kilometers); Saudi Arabia (169 kilometers); Turkiye (127 kilometers); Mexico (98 kilometers); and Canada (78 kilometers). That said, all investments aren’t equal: 57 percent of new US route kilometers will be bus rapid transit or arterial rapid transit. In many other countries, new kilometers are much more likely to be metro rail or light rail services: Saudi Arabia (100 percent); Turkiye (83 percent); and Canada (93 percent).
Brasil
Rio de Janeiro: TransBrasil, 32 km bus rapid transit route
Canada
Edmonton: First phase of Valley Line, 13 km light rail route
Among the countries in the Transit Explorer database, there will be roughly 1,900 kilometers of new fixed–guideway urban transit projects under construction in 2023, but planned to be opened after 2023. About 43 percent of those kilometers will be in the form of metro services. 554 kilometers will be under construction in the United States, 305 kilometers in France, and 172 kilometers in Canada.

» The city’s mayor has announced a multi-billion-dollar plan that would bring new light rail and bus rapid transit routes to the city’s core, but critics are suggesting it won’t work. It depends on the design.
Nashville is booming. The region that encompasses it is growing by an average of 100 people a day, and the rhythm has held up for several years now. The combined city-county Nashville-Davidson has added more than 60,000 residents since 2010 alone.
Developers are catching up, constructing thousands of new residential units, office buildings, and other projects; much of the development is happening downtown.
Yet the city’s transportation system isn’t made for the growth. The highway system is bottleneck-after-bottleneck, and the transit system is underfunded and underused.
Nashville Mayor Megan Barry’s hope is to offer an alternative through a massive new transit program that she announced in October. It would rely on voter-supported tax increases.
But the proposal could face the same problems previous Nashville transit efforts have—namely inadequate public support and vocal opposition. These opponents, as I describe below, are relying on inadequate and deceptive claims to critique investment in transit, but they’re right that the system won’t automatically be effective in attracting riders. Nashville needs better transit, but it’s got to design its system appropriately if it’s going to work.
Fixed-guideway transit for Nashville
Mayor Barry’s plan is to have the city’s voters approve a significant increase in four local taxes in a May 1 referendum. The proposal would increase the sales tax incrementally and add surcharges on existing hotel, rental car, and business taxes. Funds would raise enough to fund $5.4 billion in capital investments, plus a billion more in operations costs over the next 14 years, when construction will be completed. That’s not as large as Los Angeles’ or Seattle’s 2016 referenda, but it’s a big investment in a much smaller metropolitan area.
Indeed, Nashville’s plan would be enough to provide the city’s almost 700,000 inhabitants a large new transit network, encompassing 26 miles of light rail, 25 miles of bus rapid transit (BRT), and significant improvements to the existing bus service and Music City Star commuter rail line.
Lines would largely extend out from downtown, where a $936-million, 1.8-mile transit tunnel would separate trains and BRT services from street traffic. It would make Nashville the fifth U.S. city to invest in a modern light-rail downtown tunnel, after Buffalo, Seattle, Los Angeles, and Dallas* (like Seattle, it will include both trains and buses).
As the map below indicates, light rail lines would extend northeast along Gallatin Pike, west along Charlotte Avenue, northwest along a former rail line, and southeast along Murfreesboro and Nolensville Pikes, all major arterial routes. Four BRT corridors would fill in the gaps. The result would be an urban core generally well served by fixed-guideway transit services.
As currently described, the network would feature relatively high-performance light rail corridors, “traveling in their own lanes,” with transit signal priority and frequent weekday service. The trains would begin running 2026, with full completion by 2032.
The rapid bus corridors, which would be implemented more rapidly, would be electric, have limited stops, also feature transit signal priority, and, “where feasible and supported by the community,” include dedicated lanes and off-board payment.
In sum, the network is projected to attract significantly more riders than the existing regional network, which carries about 33,000 daily bus riders and 1,200 commuter rail users. The city estimates that the rapid bus corridors would see between 9,600 and 11,600 boardings a day and the rail corridors between 61,100 and 71,400. If these projections are realized, the city’s system will carry more riders per mile than those in Charlotte, Dallas, and Denver, and it would more than double existing use of the system.
Over the 2018 to 2032 construction period, about $900 million, or about 10 percent of the total, would go to operations and maintenance costs, with the rest paying for the massive expenditures related to the new rail and bus lines.
That’s a very capital-heavy allocation of resources, and it has its limitations. Light rail service on weekends, for example, would only be scheduled for every 30 minutes. And some local buses would continue to provide service only every 30 minutes, at best. But a new Frequent Transit Network would offer service every 15 minutes or faster on the 10 busiest bus routes, which would have significantly longer hours and an expanded fleet.
The opposition
Assuming these outcomes play out as planned, should the voters endorse Nashville’s proposal? Would the city be getting its money’s worth?
For critics of the project, massive investment in transit simply doesn’t make much sense. Vanderbilt University Associate Professor of Economic Malcolm Getz epitomizes the opposition, and he has produced a lengthy critique that’s been used by local media as evidence for the proposal’s failings. A few years ago, Getz was a key opponent of Nashville’s proposed Amp BRT line, which ultimately failed in the face of state legislative and local business opposition.
Getz’s arguments are similar to those used by most opponents of transit investment in cities across the U.S.: For one, he argues, transit does not reduce congestion and in fact may make matters worse if trains or buses take space away from cars on the street. Two, transit is slow because it requires transfers and thus will not increase ridership. Three, the benefits would go to just few people (since most people don’t use transit), and transit would accelerate gentrification. And four, the availability of new types of car services, combined with tolled express lanes, actually would be more beneficial.
These claims—like many of the popular criticisms of transit—mislead, simplify, and contradict.
It is true, as Getz notes, that the fundamental law of road congestion means roads will fill up to their capacity, so more transit is unlikely to reduce congestion in itself. But evidence does, in fact, show that transit plays an important role in reducing overall automobile traffic, even in places like Nashville where it accounts for a small share of commuters. As such, improving transit service can be an essential mechanism to move more people around a city without having to build more highways.
Getz suggests that eliminating automobile lanes for dedicated lanes for transit will exacerbate congestion by forcing the same number of drivers into fewer lanes. But such reductions in vehicle traffic have been shown either to have minimal impact on roadway capacity or actually reduce the number of people driving. Just as importantly, transit can carry a lot more people in a lot less space than automobiles on roadways.
Of course, transit can only be effective if it’s carrying people, and that’s a shortcoming that Getz relies upon throughout his criticism. He suggests, to summarize, that there’s virtually nothing that can be done to attract people onto the region’s trains and buses because they are slow and require transfers, and thus that those vehicles will be empty no matter what.
But there are ways to make transit effective—it’s just that Getz isn’t much interested in them. As noted above, he’s opposed to dedicated lanes, but those are essential for speeding up transit and actually making them competitive with cars. Nashville’s transit system is quite low-ridership today, but one reason for that is that the service it provides is slow and infrequent, exactly the deficiencies this transit plan is designed to address.
Getz’s claim that Nashville’s transit system simply won’t be well used, and thus does not deserve significant investment, is simply a reflection of existing conditions and an unwillingness to believe that cities have the capacity to change.
Moreover, he is willing to use an argument that contradicts his other claims—that transit will induce gentrification by increasing property values near transit stations. Why, though, would transit improvements increase values if no one is using the system? There is significant evidence that transit investments increase surrounding property values, and the reason for that is that transit improves accessibility. In other words, you can’t both argue that transit won’t be used and that it will increase gentrification.
Getz’s proposed solutions include increasingly relying on ride-hailing services and putting buses in tolled express lanes on Nashville’s highways. Yet encouraging people to take Uber or Lyft into downtown wouldn’t do much at all to solve congestion—in fact, it might make it worse if people are subsidized to take those vehicles instead of the bus. Moreover, given that such services are hardly self-supporting today, and far from inexpensive, it’s hard to see this approach as effective in the long term.
While tolling expressways might be effective in cutting down on traffic, putting the buses there instead of on arterial surface streets would essentially remove transit from the places where it can actually thrive: In walkable, relatively dense neighborhoods, and relegate it to an automobile-dominated corridor.
Plus, Nashville’s massive growth requires new transportation capacity. Simply tolling some highway lanes won’t actually increase the ability of the region to handle more people. That’s why it’s so important that transit investments be offered as an alternative.
What future for the city?
Despite the limitations of Getz’s arguments, they are getting play in the local press. One reason for that is that there are reasons to be skeptical of the potential for Nashville transit improvements.
As such the city should be focusing intensely to construct larger projects along the routes and downtown to ensure that the transit investment is worth it. The existing land use code also has high parking requirements—at least one space per unit for residential uses, and one space per every 200 to 300 square feet for office uses—that should be eliminated to support a transit-focused city.
This plan is better than the previous one, focusing more on improving transit in the center, where it is likely to work best. Whereas the previous proposal would have extended light rail 30 miles from downtown, this one goes, at most, about seven miles from there. While the city extends roughly 15 miles from downtown, the underdeveloped, exurban parts are not to be served by this plan. That means that it’s designed to encourage development in the core by capitalizing redevelopment of existing built-up areas. That’s the right approach.
The inclusion of a transit tunnel downtown is a radical, expensive approach, but it’s ultimately a good idea from the perspective of making the system as effective as possible. By separating trains and BRT services from traffic, the system will avoid the pitfalls of places like Portland, where light rail vehicles crawl through downtown, and make it far more feasible for people to travel from one side of the city to another.
Moreover, the plan’s opponents are missing the larger issue: This transit plan isn’t really about responding to Nashville’s current travel patterns, for better or worse. It’s about creating a framework for the future development of the city around a reliable transit system.
If the proposal is successfully implemented, it will make it possible to have a transit-oriented life in a city where living without a car is now virtually impossible. It will create the groundwork for an alternative mode of development than the parking-heavy construction that currently dominates.
Despite the vocal opposition, Nashville’s citizenry may, in fact, be willing to go along with Mayor Barry’s transit proposal. It’s a big ask, and it will hit people in their pocketbooks, but the city’s residents are hardly arch-conservative; they voted 60 percent for Hillary Clinton in 2016 despite her winning only 35 percent of the statewide vote.
Even if they vote for the referendum, though, the way the transit projects that are funded by it are ultimately designed will play an essential role in determining their effectiveness. The fact that the city is proposing to include dedicated lanes only where “supported by the community” suggests that the city’s leaders are already anticipating opposition from neighbors in places such as along the West End corridor, which connects downtown to Vanderbilt University, and where the Amp project met its demise a few years back. But the transit services will only be useful for people in the city if they’re designed to be as rapid as possible.
Better transit for Nashville, then, means more than just passing new funding for the city’s system. It means making sure that the projects built are designed to work and to actually attract riders. That’s the really difficult part.
* Several cities, including Boston, Cleveland, Newark, Philadelphia, and Pittsburgh, built light rail tunnels many decades ago and have kept them operating. Tunnels in Dallas and Los Angeles are planned or now under construction.

» Boston’s Green Line extension, bloated after years of planning, gets slimmed down. A lesson for other cities.
Given how reliant the people of New York City are on their Subway, an outsider just looking at ridership data might conclude that the system must be paved with gold, or at least its stations must be decent to look at. After all, it wouldn’t be unreasonable to assume that the comfort of a transit system plays an essential role in encouraging people to abandon their cars and get on the train or bus. That’s why, some would argue, it’s so important to put amenities like USB charging and wifi into transit vehicles.
Yet anyone who has ever ridden the Subway knows first hand that its success has nothing to do with aesthetics or access to luxury amenities. Stations are hardly in good shape, trains are packed, and cell service is spotty at best. People ride the Subway in spite of these things; they ride it because it’s fast, it’s frequent, and it’s (relatively) reliable.
Too often, this simple fact is ignored by public agencies actually making decisions about how to invest. New York’s own $4 billion World Trade Center Transportation Hub—perhaps the world’s single-most expensive station—is evidence of that; rather than improve service frequency or speed, officials chose to direct public funds to a white monument that does nothing to actually ease the lives of daily commuters.
Initial plans for the MBTA’s Green Line extension, which would extend light rail service from Cambridge into Somerville and Medford—all three are close-in suburbs of Boston—featured none of the extravagances of downtown Manhattan’s new transit terminal. Yet it too was designed with unnecessary features that, while nice, did little to actually solve the travel needs of its future users. Its projected construction costs exploded such that officials announced last year the proposal could be cancelled. Now, after several months of review, the MBTA and the state government have voted to proceed with design changes meant to significantly bring down costs—but without compromising the quality of transit service to be offered to riders.
Agencies with pricey projects around the country should look for similar opportunities to minimize costs.
A rail line for one of the nation’s most transit-friendly communities
The seven-station extension of the Green Line proposed for Boston would be the region’s first rapid transit expansion since the completion of the Red Line extension in 1985. Running along two branches northwest from today’s terminus at Lechmere—one branch to Union Square in Somerville, the other to College Avenue, near Tufts University—the 4.7 miles of new track would run along existing commuter rail lines and connect to some of the country’s densest, most transit-friendly neighborhoods. See the Transit Explorer map for details.
The project would vastly improve connections of Somerville and Medford residents to jobs hubs in Cambridge and Boston and is expected to attract 45,000 daily riders by 2030. That would make it one of the most effective projects in the nation from the perspective of riders per mile operated.
The project has been in planning for decades. A 1990 lawsuit required that the line be completed by 2011 as a sort of trade-off in exchange for the completion of the Big Dig. But faced with limited funding, mounting MBTA debt, and a lack of adequate state political support, the project failed to gain traction and the state kept pushing it off. Finally, initial construction activity began in 2013 and the federal government agreed to provide a significant New Starts grant to the project in 2015.
Yet even as the project advanced, its estimated construction costs mounted ominously. Federal reports show total costs rising from $1.1 billion in 2013 to $1.7 billion in 2014 to $2.3 billion in early 2015. By late last year, the project’s budget had reached $3 billion, and the state announced that it was not only cancelling certain contracts related to its completion but also that, in the context of a transit agency stretched beyond anything it could handle, it was considering cancelling it altogether.*
Redesign by necessity
But the MBTA submitted the Green Line extension to a review by a project management team, and that group released its report on how to save the project yesterday. The document details how the project’s price tag could be substantially reduced, returning it to a (still-expensive but) doable $2.3 billion cost.
The changes are reasonable because, rather than cutting the quality of service provided to riders in terms of transit service, they focus on aesthetic elements that, even if they improve the general atmosphere of the system, likely do little to actually get people onto trains. The essentials, like the frequency of trains, their speed, and their capacity, are maintained.
What the team does recommend is vastly simplifying proposed station designs. As the below chart from the report indicates, the stations would be slimmed down. 15 elevators would be replaced by six (while maintaining wheelchair accessibility throughout); escalators and fare gates would be eliminated entirely; and full-length station canopies would be cut down to shelters. In total, these changes would slash almost $300 million from the project budget, with virtually no impact on ridership experience.
The changes will make the MBTA’s built footprint less visible; there will be no Calatrava extravagances here. As the below images show, Ball Square station in Medford was initially designed to feature a plaza, a headhouse (a multi-story building featuring elevators and escalators), a concourse, and a fully covered platform. What would be built in its place is an open-air and very simple train stop, with more room for future transit-oriented development.
Customers may suffer through the cold for a few more minutes, but trains will come frequently enough that shouldn’t be a major concern. Meanwhile, MBTA will save itself millions of dollars of future maintenance costs not upkeeping expensive and unreliable machinery and not keeping thousands of square feet of interior space clean. These savings aren’t even accounted for in the capital costs of the project but they’ll pay off in a lower operating budget for years to come.
Initial proposal
Revised proposal
The management team also proposes a reduction in the size of the proposed vehicle maintenance facility and affiliated transportation building, which together will save more than $100 million and not affect the MBTA’s ability to keep trains moving. An expensive parking deck will be replaced with a parking lot. Bridges that the initial plan suggested needed to be completely replaced will be simply renovated.
If the choices about what to eliminate seem obvious, consider the alternative: The Purple Line in suburban Washington, D.C. also underwent a considerable cost-cutting process earlier this year. Yet the changes there will reduce passenger quality of service by increasing headways between trains, reducing train capacity, and lengthening the walking distance between the line and a Metro station in Silver Spring. While these efficiencies aren’t dramatic enough to imperil the overall value of the line, they will hurt the passenger experience in the long term, while those on the Green Line will not.
The changes in Boston must be approved by the Federal Transit Administration, which has final say over whether the redesigned project meets the initial project goals. And local governments need to scrounge up an additional $73 million to meet the gap in project costs that remains—without this funding, the project could still be on the chopping block. Yet these are surmountable obstacles and the project now seems likely to move forward.
Nuance by design
Boston’s example is no panacea; the quality of the transit environment does matter. While nice materials, enclosed stations, escalators, and overhead canopies may do little to expand ridership, they improve peoples’ daily experience, and that’s important. The nicer we can make the public sphere, the better our cities will be to live in.
But it’s refreshing to see a transit agency propose a cost-cutting approach that does nothing to negatively impact the level of service being proposed. Rather than take out a constricted budgetary environment on riders by reducing service, the MBTA is proposing to stick to the essentials, and that’s the right move.
Were construction costs in Boston lower, the MBTA could afford to give riders both good service and a comfortable environment. But like transit agencies around the country, the MBTA has been unable to lower costs to international standards. In this environment, it serves as a model for other agencies looking to invest in transit on a limited budget.
* There is some question as to whether the state actually can ever cancel the project, given that it was mandated through the legal process.
