If the train west of Denver hit 220 mph, I wonder how much air it would get when it hit the continental divide.
I read an article a while back that I found quite interesting. It said that around 1910, the U.S. had a big decision on whether they would build the infrastructure for an automobile-based system or a train-based system. They chose the automobile, obviously, but the article intimated that it was really a judgment call with no clear winning argument. If they had gone the other way we'd have a lot more trains and probably no interstate highway system.
My past posts echo through the hallowed halls of Chiefsplanet.
