Faster than a speeding car. Exactly as powerful as a locomotive. Able to leap absolutely nothing. Look, up on those tracks! It's an engine! It's a caboose! It's Supertrain!
Say what you like about abandoned steel works, space ships, and Nakatomi Plaza, there's just no better place for an action scene than the top of a train. Even crappy terrible not really a Bond movie at all Skyfall got that much right. There's speed, and height, and danger, and excitement, and OH BOY I HOPE HE DUCKS BEFORE THEY GET TO THAT TUNNEL OR SPLAT! Ahem. Anyways, trains are awesome.
