Hello, I am hoping that the Forum could help me identify a pair of O gauge 3 rail A Units that a customer brought in for repair. They are red PRR with a silver stripe along the top. The truck sides look to be brass and the truck bottoms are aluminum with a raised area such as for a gear clearance, Also they have unique aluminum couplers that have a square end on the top and a long round tab that hangs down about 7/16 below the coupler. The powered unit has an E Unit or power switch lever at mid ship at the very bottom.I think they are circa 1960? They have no cab numbers or brands I will try to get some photos tomorrow. Thank you in advance--- Jim
