I was just thinking about this. What motors do diesel-electric trains use?

Whoah. That's almost 3 tonnes for one electric motor. I'll stick to the 9" for now.

The article said they pull up to 1100 some amps, but never listed an operating voltage. Hmm... It states that the head generator (used for all other electricity across the train) is a 480v 3-phase AC, but the main generator (used for drive motors) doesn't have a listed voltage.
