What Have You Done For Me Lately?

In the "what have you done for me lately?" department this article, "Sounder commuter rail facing growing pains" raises some question over the fiscal responsibility of rail as public transit. The article is from 2006. Since then the southern Sounder route has continued to do well but the route from Everett continues to flounder. How much longer does it make sense to hemorrhage money into this when funding for transit is in short supply? When one of the major obstacles to increasing transit usage is over crowded buses should Sound Transit continue to shell out four times the cost per rider for the relatively few that use an under utilized rail line?
