On Amtrak cars I noticed there are little green lights(on the outside) on each one pointing straight to the next car. My question is what are they there for?
I still don't know what that means...the brakes have air and work? I was beginning to think I was the only one to see those lights. Thanks I don't know much about the operation of a train.Actually, they are brake indicator lights.
