Trainline Connectors

Metal, Push Pull Coupling, Harsh and Hazardous environments, Power Connector

All Amtrak special service receptacles are modifications of Pyle-National’s standard Trainline connector MU (multiple unit 27 pole receptacles). All parts are common to all other 27 pole receptacles except the receptacle housings, which are keyed differently to prevent inter-mating of any other 27 pole jumpers. Receptacles can be supplied with or without leads. Wire configuration, per Amtrak standards, calls for 1-#10 wire, five shield twisted pairs, and balance #12 wire. Jumpers are keyed differently from all other 27 pole jumpers to prevent mis-mating. Plug housings are painted blue to match the blue painted receptacles. Jumpers for use between locomotives and between locomotives and lead cars have a suffix “LOCO” following AMTR of the jumper part number. This indicates that the wiring circuitry is different than for car to car jumpers and are not electrically interchangeable.
