Transit Project Openings in 2024: A Global Review

Despite the ridership struggles facing transit systems in the United States, nations and cities around the world are investing dramatically in new lines. In this annual post, I review what projects were completed in 2023—and what’s coming over the next year.

Data for this compilation can be viewed freely on Transit Explorer or purchased for use in Shapefile, GeoJSON, and CSV formats. Transit Explorer has been dramatically expanded since last year, now covering metros—as well as many other types of lines—around the world. In addition, the interactive website for the first time allows users to “turn back the time” by seeing what transit in each city looked like in the past.

Previous compilations of new and planned transit projects on The Transport Politic can be found here: 2009 | 2010 | 2011  | 2012  | 2013  | 2014  | 2015  | 2016  | 2017 | 2018 | 2019 | 2020 | 2021 | 2022 | 2023

New transit investments completed in 2023

In 2023, 1,760 kilometers of urban transit—meaning fixed-guideway rail and bus projects within metropolitan areas—opened for service around the world. 1,100 new stations opened along those lines, although many other already existing stations got new service, too. The trends in 2023 represented a continuation of recent trends; in 2022, 1,819 kilometers opened, and in 2021 1,795 kilometers opened.

The majority of the new service came in the form of metro lines, including subway, elevated, and monorail services, which accounted for 64 percent of the total new route mileage. New light rail options added another 10 percent; commuter rail and regional rail another 16 percent; and bus rapid transit routes about 6 percent.

The new lines were concentrated in China, where 45 percent of new route kilometers opened, almost all of which were in the form of metros. That said, Russia (11 percent), the United States (5 percent), Thailand (4 percent), and India (3 percent) also added substantial new transit options. Overall, European Union countries added about 5 percent of new routes.

Major projects that opened included:

  • Bangkok Pink and Yellow Line monorail lines;
  • Beijing Subway Line 17;
  • Chengdu Metro Line 19;
  • Chongqing Metro Line 18;
  • Dalian Metro Line 5;

Historical Trends Show a Decline in Investment in High–Quality Transit in the US—And an Uptick Elsewhere

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).

(Relatedly, for the Urban Institute’s Urban Wire, I calculated key trends in housing adjacency to rail and bus rapid transit stations in the US, as well as Canada, England, and France.)

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.

Openings and Construction Starts Planned for 2023

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 greeted enthusiastically 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.

On separate posts, I analyzed trends in transit investments around the world and examined accessibility to transit stations in the US versus Canada, England, and France.

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 Explorer now 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.

Data can be viewed freely on Transit Explorer or purchased for non-commercial use in Shapefile, GeoJSON, and CSV formats for those who would like to use the data for research or other uses, such as in Excel, R, ArcGIS, or QGIS.

New transit investments completed in 2022

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).

DOT Elections Infrastructure United States

The path to a better transport system runs through progressive states and cities

We’re two weeks out from the 2020 United States presidential election, and the winner will undoubtedly play an important role in directing American urban policy. Given the importance of the presidency and the high stakes of the position on every policy area, it is hard not to focalize on this electoral race as key in establishing what sort of future the United States will have.

Hoping to respond to the economic crisis brought on by COVID-19 and the prospect of Democratic control over both houses of Congress and the White House, Senate Democrats have begun preparations for a $1 trillion infrastructure package. If the legislation pulls from this year’s House-passed H.R. 2 and from Joe Biden’s presidential platform, the legislation could include new funding for electrification; increased support for transit and intercity railways; and requirements that states “fix it first” before expanding highways. These are good concepts, and indeed, there is a lot of room for federal intervention, especially when it comes to filling the gaps left by declining tax revenues over the past several months, particularly when Americans support a potential big federal stimulus by an enormous margin.

Yet the key questions regarding transportation in the United States—whether the country is able to truly adapt its mobility system to mitigate the devastation wrought by climate change; whether we integrate transportation and land-use planning so as to reduce exurban expansion and automobile dependency; whether we harness access as a tool to reduce inequality, rather than as a mechanism to further empower and enrich a lucky few—are in fact more often than not in the hands not of the federal government, but rather in those of elected officials at the state and municipal levels.

This reality of the U.S. federal system will continue to be the case no matter which presidential candidate wins the election, and no matter how exciting their proposed policies may be.

States and cities make most choices on transportation infrastructure—and their choices have been regressive

The federal transportation legislation authorizing expenditures on transportation—reauthorized every five years or so, and known by such acronyms as FAST, MAP-21, and SAFETEA-LU—is typically the big story when it comes to transportation (though it may not be next year, depending on the scale and inclusiveness of a new infrastructure-focused stimulus). It’s essential for members of Congress, who can advertise it as meaningfully contributing to their respective district’s surface transportation infrastructure needs, to the tune of an average of more than $60 billion annually nationwide. It’s important in defining the overall patterns of spending, such as the share of funds to be distributed to road projects versus transit investments.

Despite this avalanche of funding from Washington, the administrators at the U.S. Department of Transportation are not the primary decisionmakers when it comes to what actual planning choices are made about new transportation projects.

The failure of the Obama Administration to make good on its proposed intercity rail plan is a case in point. After convincing Congress to devote billions of dollars to a national network, high-speed rail became a policy against which to rally among conservatives. Several states run by Republican governors simply sent back grants (free money!) the administration had allocated to them.

The result, then, was that a theoretically national plan for investment became a series of planning choices made state-by-state, each picking whether or not they wanted to engage in the overall program. One can imagine a similar outcome if a future administration makes a similar push for new rail investment.

Moreover, the U.S. government distributes transportation funds primarily by pre-determined formula to states, cities, and transportation agencies. For example, in 2020, of federal highway funds more than 90 percent is distributed directly to state governments to do, largely, what they wish.

It is true that certain programs, like the New Starts transit capital program, are more discretionary in that they give the U.S. Secretary of Transportation more oversight over what projects to advance. But, for the most part, even programs like that are largely formulaic; if you follow the rules for developing a transit project, and it scores well enough based on standardized criteria, you can get it in line on the federal list.

Those lower levels of the public sector, in fact, are those that make most of the choices related to what roads should be built or expanded, and what transit lines to promote.

Indeed, consider how different levels of government have distributed funds to transportation. Between 1956 and 2017, the federal government allocated a total of about $3.1 trillion in 2017 dollars to highways, transit, and rail investments around the country (most of which was simply sent down to lower levels of government to spend). During the same period, states and localities spent way more of their own funds: $8.9 trillion.

Since 2000 alone, the story is similar: The federal government has devoted roughly $1.2 trillion to surface transportation, while states and localities have spent $3.4 trillion raised by their own sales taxes, gas taxes, and the like.

In other words, not only does the federal government largely allocate decision making about what transportation projects to build to states and localities, while handing them control of most of the money that it raises, but also states and localities raise way more money that they use to spend on their own objectives.

U.S. governments at all levels have contributed to an infrastructure system that prioritizes road-based travel above all else. Transport Databook.

Unfortunately, neither the federal government nor lower levels of government have been particularly effective custodians of their massive expenditures on transportation—at least when it comes to achieving more sustainable and equitable outcomes. Since 1956, the federal government has devoted just 21 percent of its surface-transportation expenditures on transit or rail investments; states and localities, just 22 percent.

In other words, both have participated in the creation of an American society dependent on the private automobile for most of its function.

An infrastructure stimulus won’t be equitable or sustainable without buy-in from states and cities

If Democrats take the presidency, retain control of the House, and inherit the Senate, they are likely to push a new federal stimulus bill. It may well offer billions of dollars for improved transportation infrastructure, and if you take what Democrats have said over the past year seriously, it will include a vast expansion in support for transit, new climate-focused policies, and a renewed national rail program.

Yet the role of states, municipalities, and other public-sector entities will only be heightened if a stimulus is passed. States will be the entities deciding whether to participate in bringing improved inter-city rail to their communities. Cities will have to determine whether they want to use federal funds to renovate streetscapes to prioritize pedestrians and bicyclists. Transit agencies will have to identify new bus and rail projects that serve the most passengers.

In other words, even with new federal funds, lower levels of government are ultimately those entities making choices about what kinds of projects they want to build. And there’s little stopping states and cities from spending their own money on new highway expansions that encourage pollution, sprawl, and further exacerbate inequality. Because of the focus on what happens in Washington, however, the actions those entities take is typically less visible. Road projects continue at a reckless pace throughout much of the country despite what we know about climate change.

Fortunately, some states have made progress. California, for example, has altered its system of measuring street performance away from prioritizing moving cars. Yet localities in that state continue to push destructive road investments.

Along with a federal stimulus, then, we need action for change within lower levels of government.

General Infrastructure

Openings and Construction Starts Planned for 2020

20 new transit lines will open in the U.S., Canada, and Mexico in 2020.

These new transit lines won’t be adequate alone to counter the large-scale investment in highway construction that dominates most metropolitan regions. But they will significantly improve public transportation for thousands of riders in many large cities.

There’s also a lot more on the way. About 60 more major transit projects will be under construction in 2020 and are expected to open by 2026. Some cities, like Montréal and Seattle, will essentially double the size of their urban rail systems during that time.

Transit Explorer
Use Transit Explorer 2 to examine current, under construction, and proposed transit projects throughout North America.

This compilation of new transit projects is based on The Transport Politic’s transit database, Transit Explorer 2. This database is frequently updated and provides information about existing, under construction, proposed, and cancelled fixed-route transit throughout North America.

Thanks to support from Chicago Cityscape, Transit Explorer 2 is much faster and more usable for people accessing the site than previous versions.

In addition, the data it includes has been improved and expanded dramatically compared to the past. It includes almost 7000 transit stations (including for commuter rail, not previously included), and almost 1000 transit lines. Now additional information, such as the year that stations were opened and their grade—e.g. subway or elevated—is also available.

Data can be viewed freely on Transit Explorer 2 or purchased for $25 in Shapefile or GeoJSON formats for those who would like to use the data for research or other uses, such as using ArcGIS or QGIS.

New transit investments completed in 2019

In 2019, roughly 200 miles of new fixed-guideway transit service was opened throughout North America; these projects cost a total of roughly $7 billion to complete.

In Canada, the most exciting intervention was the opening of the Confederation Line in Ottawa, which includes a new downtown tunnel and a light rail network that replaces an oversubscribed busway; it is designed to eventually carry about 240,000 daily riders. The Confederation Line’s benefits will be magnified by several extensions planned for the next few years.

In the U.S., the opening of a new busway on 14th Street in Manhattan attracted considerable attention, as the project immediately increased transit ridership but did not ramp-up surrounding traffic. It may be a model for other American cities looking to improve their bus options—demonstrating that giving bus services dedicated lanes and freeing them from being stuck behind cars is an effective way to get people to ride.

Planned openings in 2020

In 2020, several long-awaited projects will open across the continent, including three heavy-rail routes, two new light rail lines, two commuter or regional rail extensions, and 13 improved bus projects.

In Vancouver, the metropolitan region has already opened four RapidBus bus rapid transit routes, which include dedicated bus lanes, queue jumps, all-door boarding, and relatively high levels of frequencies. A fifth new line is planned for opening in April.

In Miami, a new downtown rail link will leverage the infrastructure built by Virgin Trains to extend the region’s Tri-Rail commuter rail system into the center of the city for the first time.

But the largest investments by far are being completed in the Honolulu, Los Angeles, San Francisco Bay Area, and Washington regions. In Hawaii, the first phase of that state’s first rail line—an elevated route—will open. In Los Angeles, the Crenshaw Line, a $2.1 billion light-rail route that includes a subway portion and a new station near LAX Airport, will be completed. In the Bay Area, the BART rapid transit system will continue its slow path toward downtown San Jose with a $2.4 billion extension to Berryessa station. And outside of Washington, the Silver Line will finally reach Dulles Airport, thanks to a $2.8 billion extension

Each of these projects is considerably delayed compared to original projections. Honolulu’s rail transit first phase was supposed to open in 2012; the Crenshaw corridor was supposed to open in 2016. BART’s extension all the way into central San Jose—now put off for many years into the future, was supposed to open in 2018. And Metro service to Dulles was originally planned for 2016.

A busy decade to come

Despite the relatively limited investments made in transit improvements in the 2010s, cities throughout North America will expand their fixed-guideway transit networks substantially beyond 2020.

In this final section, I document all of the transit projects in the U.S., Canada, and Mexico that are already under construction or will enter construction in 2020 (at least preliminary work will be underway), and thus that are highly likely to be completed. The same cannot be said for the dozens of other proposed projects on Transit Explorer 2, many of which will fall to the wayside thanks to funding crises, political backlash, and other problems.

Four metropolitan regions will see extensive improvements to their transit systems in the coming years if projects under construction this year are completed.

Montréal will open the new REM automated heavy rail system in phases, roughly doubling the scale of its current metro network and creating new transit links throughout the metropolitan area.

Thanks to referenda passed in 2016, both Los Angeles and Seattle will open large new extensions to their rail networks. In L.A., a new subway line will open to the west side, making travel to UCLA far less burdensome, and a light-rail subway downtown will allow commuters to travel from the west to the east side of the region without having to change trains. In Seattle, meanwhile, new light-rail extensions will open south, east, and north of the existing route, creating a regional transit network out of what is now a relatively limited service.

And in New York, the opening of the East Side Access project—which will bring Long Island Rail Road trains to Grand Central Terminal—and the Penn Station Access project—which will bring Metro-North trains to Penn Station—will radically improve the accessibility of the region’s central business district. The two projects will make it possible for people commuting from Connecticut and Long Island to have direct access to both the east and west sides of Manhattan’s central business district, saving hundreds of thousands of people each up to an hour a day in travel time.

In addition, Vancouver is expected to complete the first phase of its subway underneath Broadway—now the heaviest-used bus corridor in North America. Honolulu will complete its rail project. Boston will expand its urban rail transit system for the first time since the 1980s. San Francisco will get a new subway downtown for light-rail trains. And Washington will get the U.S.’ first true circumferential transit line with the Purple Line light-rail project.

Despite the massive investments planned throughout North America in the coming years, cities throughout the U.S. and Canada should be investing considerably more in improved transit—especially through better buses. These countries continue to under-allocate street space for buses compared to much of the rest of the developed world, and the result is that most cities are failing to take advantage of the lowest-cost mechanism to improve public transportation options and reduce automobile dependency.

We can only hope that, as we move into the 2020s, more cities will learn from New York’s success on 14th Street and find the political means and financial capacity to dedicate more space on their streets to people, rather than to cars.
