I don't see how it will be sustainable. The maintenance on this thing is going to be crazy, as well as paying employees, etc. Tickets are going to cost $25-30, which isn't horrible, but I'm not sure the mass appeal is going to be there like some are predicting. Car travel is an ingrained way of life for most Americans. I'm just not sure if most people want to park near the train station, wait for the train, travel to Madison, take a bus or cab downtown, find a way back to the Madison station later on, etc. I hate to say it, but I think most people are too lazy or lack the forethought to plan ahead for something like that.
