27 Pole Train-Line MU and Communication Receptacles and Jumpers
Train-Line Power Connectors by Pyle National

All Amtrak special service receptacles are modifications of Pyle-National's standard MU (multiple unit 7 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. SUFFIX L (followed by a number) - Indicates length of leads in inches and housing painted blue. S500 series suffix indicates a deviation from standard.
