If we wanted to build an efficient passenger rail system for max use in the states, we'd have to suspend a metric ton of laws at every level of government, exercise a serious amount of eminent domain and essentially tell every lawyer in the nation to get bent. Personally, I'd love to see it happen. But given the extreme cost and snails pace of most large infrastructure projects we have, I won't hold my breath. Last I read, just to rebuild a bridge that was already there (F Scott Key), it's going to cost $2B and take another four years. Of course that's before any budget increases and delays due to whatever litigation can be dreamed up.
