TriMet issued a statement crowing about the success of the Westside Express rail line (the one that runs between Wilsonville and Beaverton, nicknamed "WES"). It opened one year ago, and according to TriMet 42% of the people who ride WES are making trips for which they used to drive their cars. That's an outstanding statistic, if you don't know that WES averages only 1200 riders a day. WES runs 16 trips each way on weekdays, or 32 trips total, so each trip averages about 40 riders.
WES cost $160 million to build. To put that number into perspective, the numbers being bandied about for the cost to replace the Interstate Bridges, build lots of ramps, bring light rail to Vancouver, and save civilization are in the range of $5 billion, or about 30 times the cost to build WES. About 126,000 vehicles use the Interstate Bridges each weekday, which at 1.2 occupants per vehicle means about 150,000 people. That's 125 times the ridership of WES, at 30 times the cost.
Comparisons are invidious, of course; the cost of the Interstate Bridges doesn't include the cost of the road network that gets cars to and from the bridges. Similarly, the cost of WES doesn't include the cost of the road and transit network that gets riders to and from the WES stations. These numbers do suggest, however, that instead of crowing about WES, TriMet should be working hard to bring its capital cost per rider down to the efficient level of the highway system.
