I’m still having a hard time justifying the time and expense of MetroLink light rail over streetcars.
Others have made good arguments in favor of light rail, including the ability to move large numbers of people at high speeds which results in substantially lower travel time.
While I have some interest in MetroLink making its way into various parts of the county surround the City of St. Louis it is here in the city where I’m mostly concerned. I assume we still have the greatest population density of the region and we can certainly handle an increase in population. I see an excellent in-city transit system as a means of attracting more city residents. Transit as a means of shuttling suburbanites the 20 miles from their split-level ranch to downtown is a lesser priority for me. Yes, I know that if we get them on rail it is one less car (or SUV) they’ll drive into the city.
But I want a first class transit system in the City of St. Louis. And first class doesn’t include buses. The Northside and Southside MetroLink routes currently being planned include much of their route at grade — that is in dedicated medians in the center of streets such as Chouteau and Natural Bridge. These routes will also make a loop around downtown at grade.
Here is a good opportunity to look at what would happen if we substituted streetcars on the route exactly as planned. First myth we have to dispel is that streetcars run in the street and have to compete with traffic. Not true. Look at New Orleans and you’ll see a couple of routes that run mostly on dedicated medians but running in the street as needed. The same is true of San Francisco with their streetcar lines. Ditto for Portland.
Portland’s streetcars have a modern look — not retro lines as in New Orleans and San Francisco. On the surface you’d be hard pressed to tell the difference between Portland’s streetcars and light rail. But when you look closer it becomes more apparent:
The Portland Streetcar is designed to fit the scale and traffic patterns of the neighborhoods through which it travels. Streetcar vehicles are 2.46 meters (about 8 feet) wide and 20 meters long (about 66 feet), about 10 inches narrower and 1/3 the length of a MAX (TriMet’s light rail system) double car train. They run in mixed traffic and, except platform stops, accommodate existing curbside parking and loading. The Portland Streetcar is owned and operated by the City of Portland.
Size is a big factor in that streetcars are narrower and shorter than a typical light rail train. This allows for them to maneuver through the streets. Metrolink’s planned loop through downtown at grade certainly means they’ll have to pick a different car stock than our current system. The narrower and shorter trains also mean fewer passengers per run (but still greater than a bus).
At this point an in-median streetcar system and in-median light rail look very similar. Both are operating on a dedicated right of way and are most likely similar in size to each other. I’m far from an expert on these systems so at this point I’m speculating but rail type and speed are probably the main differences. Portland brags about how its system required little in the way of construction but light rail is certainly a bigger undertaking because of the speeds. The bed for the rail is more massive and crossings require gates. Money aside, fewer crossings for light rail verses streetcars means those walking or bicycling will have fewer places to cross the lines. This is a net reduction in our interconnectedness.
My problem with in-street MetroLink is that it not friendly to other modes of transportation. The cost of street crossings is high enough that pedestrians, bicyclists, scooterists and auto drivers will all have to make right turns coming from side streets until they get to the next crossing. With streetcars in the same median you could have crossings not necessarily every block but certainly more often. The downside is a slowing of transit time. Compared with bus service on the street and stopping every block, streetcars are a good middle solution between buses and light rail.
The number of stops affects transit time but also convenience. In particular the Northside route has the potential to renew interest in a long-neglected part of the city. The number of proposed stops along Natural Bridge is more frequent than our current system, ranging between 0.4 miles to 0.9 miles. I’d argue that the in-street/median portions of these routes should be designed more like the streetcar lines in New Orleans and San Francisco where they are easily crossed by pedestrian, bike or car. When they get into the old rail right-of-way let them pick up speed there. Think of it has a hybrid streetcar/light rail system.
