Read the original question. He asked how they stayed centered on the rails. Gravity keeps them ON the rails. Toe-in is also a clue, but where?

BTW, locomotives are diesel-electric. The engine turns an alternator converting the rotating power to electrical power which is piped to traction motors. They used to be exclusivly DC but are now AC. A chopper circuit is used with BF'n semiconductors to convert the DC electrical power to AC. Speed sensing circuitry keeps the motors at peak efficiency and doesn't allow for wheel slippage. RUN 8 all the time!

What you want, when you want it. AMEN!
