Apart from the Northeast Corridor, (PBUH), there are no passenger trains anymore and have not been since the 1960s. The airlines and the Interstate Highways killed off the market for train travel. In spite of all the TSA madness associated with flying these days, no thanks to the beardy ones who caused the security precautions to be ramped up, may Allah curse them, it's still faster and cheaper to fly to your destination.Decrepit stations, no information (staff follow rules saying do not ask for help). Trains dirty, slow and full of weird people. Stations designed as an example of what the world will be like when trologdytes rule the earth (hello Penn Station).
As for weird people riding trains, a lot of them are immigrants, especially in the NYC area, and wouldn't actually look out of place on the London Tube. Native born folk avoid the train if they can. I've had a few WTF moments on the train. I was traveling to Independence Hall in Philadelphia with my son by subway and we saw a drug bust go down. Two undercover vice squad cops started hassling this gentleman of the darker persuasion and told him his drug dealing days were over. My kid thought it was cool like a TV show, but I knew it was a tricky situation and hustled him out of the car. I wouldn't have minded watching it unfold if I had been by myself, but you have to think of the children.
