Many US commuter-rail trains also have reversible seats. The train crew generally orient these to be forward-facing for the direction of travel, possibly excepting the first seat in a car. (The trainsets reverse directions without being turned around themselves. Those using locomotives rather than electric traction operate in "pusher" mode for half their trips. There's an operator cab in the end car for such trips.)
