Beyond DC has a great post about the Department of Transportation soliciting proposals for high speed rail corridors. This is a great development, one step closer to catching up to the rest of the civilized world with a real train network.
As these corridors are planned, I really hope there is a serious effort to build the HSR lines along interstate highways. This minimizes the need for right-of-way acquisition, and it makes our interstate corridors multi-modal. I imagine in some areas it may drive up the cost of construction, but as long as we have these corridors already built and engineered for high speeds, I believe it makes the most sense to put the trains there too.
In any event, I'm very excited about the prospect of being able to hop a train to Chicago and get there in less than 20 hours. With any luck, I'll be able to do that before I retire.
