Trains don’t have steering wheels for turning. There are people at a central hub changing track switches to move trains from one track to another. They don’t call it left or right, they probably use more meaningful terms like northbound/southbound track.

Ah, so its the central hub people that tell the Frankford-bound El drivers to take a left go northbound instead of going straight to New Jersey. Never knew!

edit: I'm catching on!
