I didn't know they labeled steam engine with day and night signals as to whether the were going forward pulling the train, or running backward pushing the train.
The pulling engine was also marked as to whether there was one pushing or not.
I can understand if an engineer suddenly sees another engine on the same track facing him, it's nice to have signals to tell him if it's pushing a trrain or to bail out. But I don't see why the pulling engine would be labeled that there's a pusher at the other end?
