Dallas is building a light rail system. I was reading about it in relation to this discussion: http://www.dallasobserver.com/news/dart-has-spent-5-billion-...

It doesn't seem to be working all that well yet. Expensive on a passenger mile basis with not all that many riders. But not hopeless either.

I guess optimistic transit corridors are something that is a good fit for federal spending. Ever bigger cities aren't really good for anybody, but they also seem to be self reinforcing, where a bunch of economic factors work better when density is already high.
