I'm sorry train lovers. Trains are romantic, but interurban busses are much more practical in the US. Busses are more efficient, faster*, safer, cheaper, and pollute MUCH less Even more important, the infrastructure they need is already in place.

*Faster in the US currently. Busses move at 70 mph, most rails are in bad shape and have speed limits of 65 mph or less until enormously expensive upgrades are done. Rather than putting the money into heavy rail improvements, let's think about developing maglev and other truly high speed rail systems to compete with air travel.
