Light Rail? Lite Impact!

It’s interesting to remember that when Seattle tried to build a transit system in the late 1960s (defeated in two votes), it would have been a heavy-rail system like those in Manhattan or Washington D.C. Transit advocate Jim Ellis used to make the case for heavy rail by arguing that light rail had small trains and short stations, and was too slow to have much effect. But light rail is what Seattle, like many other cities, ended up with. The main reason is that after early cost-overruns for heavy rail, President Reagan sharply cut federal funding. Cities still needed transit and light rail was much cheaper.

How has this worked out? Not very well. A survey in CityLab concludes the gains from light rail, such as the system in Seattle, are marginal. Light rail ridership has barely budged since 1990, while heavy rail shows significant gains. Bottom line: “Most light-rail systems fell short on attracting significant new crowds of riders or shifting commuters away from their cars. ‘They were sold on the idea of reducing congestion, and that didn’t happen anywhere,’ said Jeff Brown, a professor of urban planning at Florida State University. In Sacramento, San Jose, and Pittsburgh, transit’s overall mode share has declined since the early 1990s. San Diego’s has stayed flat. Even Portland, Oregon, which probably has the most fleshed-out light rail network in the U.S., has gained only a couple of percentage points in its portion of commuters using transit since its MAX opened.”

Part of the reason is capacity (shorter trains) and speed (at street level). Many of the light-rail lines, to save money, followed existing freeways, which put them far away from residential areas. The unrealized hope was that drivers who disliked the negative aspects of bus riding would be attracted to the cachet of rail (so-called choice riders, rather than captive riders). That meant light-rail lines extended out to upscale commuters (who continued to resist transit), rather than connecting urban tissue. There was little integration with bus lines. Meanwhile, light rail was quite costly, and those tax dollars were subtracted from bus systems — another blow to class and racial equity.

Still, there are some plus factors. Light rail does stimulate development and retail, and has been part of urban revitalization and placemaking. They certainly score better than trendy streetcars, which have tiny numbers of commuters. They do better than buses in farebox revenues. They generate juggernaut transit constituencies and pass huge bond issues. Their day may yet come, as systems mature.

But for now, light rail is another awkward stepchild of the Reagan austerity.

  1. Read Sound Transit’s response to the essay Dave Lange and I published in late 2018 suggesting that Seattle’s light rail trains would be too small to handle peak loads as it extends northward from the U District, beginning with Northgate opening in 2021 and Lynnwood a few years later.

    Bottom line: Seattle light rail works like heavy rail and is plenty big enough.

    Quoting Sound Transit staff: “In the 1990s when the region took action to move forward with building a high-capacity regional transit system, the light rail system at the core was designed to provide substantially greater capacity than many others around the country. Each station was designed to include platforms stretching 400 feet, one third longer than a football field, and long enough to accommodate four-car light rail trains. Our system was also designed for faster speeds and higher reliability that come from a predominantly grade-separated system.”

  2. I wish our region had gone with dedicated bus right of way as the best of both worlds. I find our light rail cars too small and slow. I’m not that tall and my knees bump the seats. But the debate is over. We have to keep trusting Sound Transit.
