I love watching out of the back window. It's easiest to do on Amtrak long distance trains with Superliner cars. No obstructions.
More difficult to do on the commuter routes. Cab cars are sometimes off limits, though a conductor did let me look out the back window once.
Easy to do on the light rail routes, but I was hassled by a security guard for taking photos once. Said that I might be a terrorist trying to take a picture of the controls or something. Nonsense.
