AirTrain, which carries passengers between JFK terminals and a couple of miles to the Jamaica train station, runs completely without operators, with no room allocated for an operator, you can peer through the windshield forward. It works quite well.

But it was built this way, there were no operators to lay off, and no unions to bargain with.

Actually, there were unions to bargain with. The people wearing red at the station saying which train is which are from the same union.
