To some degree, definitely. I'm just not sure how far they purposely went with it. The US highways system was entirely planned around it being an airstrip for military operations, if necessary.
I think part of the reason trains are less favored now is the economics of a single provider. As long as there's competition, the passenger or freight space purchaser wins. But there was a wave of railroad bankruptcies which left a single provider in a lot of regions. I'm pretty sure its all the government's fault - first for inflating liquidity with credit money and getting the crash, and then by regulating and subsidizing. A free market can't survive a Democratic government... The only thing free markets need is to be left alone, and that's the only thing a democracy can't do.
There was a deliberate attack on a Japanese subway that killed a bunch of people - the attacker made a chemical and put it in the ventilation. That's all I remember, but its enough to make me nervous on subways. That and all the thugs. Its just not safe.
