Ironic that you'd say that, since in Third World and poor Old World countries train is by far the most common mode of transportation. And when it's not a train, it's a bus, short-haul trains for the poor masses. Only in a modern and prosperous capitalist country do you find middle class citizens owning automobiles, free to travel where they will.
Personally I kind of like trains and don't understand why they are not more successful, considering that it's one of the most efficient modes of transportation. My wife and I even planned a long train trip, but from our home that meant roughly fourteen hours minimum sitting in coach before we could transfer to a sleeper car. Oh wait, now I remember why trains are not more successful . . .
Anyway I think the left only likes trains because they know "someone else" will have to subsidize their travel.
