Car control/communication trainlines are employed throughout the entire length of the car to transmit the electrical signals that operate door controls and indicators, public address systems, and brake applied/released indications. Multiple unit locomotive control trainlines carry traction and dynamic brake commands and indications between equipment, typically: locomotive to coupled locomotive, cab car to locomotive, and locomotive to a power car positioned at the opposite end of the train. The Cadillac cable assemblies are environmentally protected by individual contact sealing boots as well as an outer “O” ring. A locking tab holds receptacles’ cover open to facilitate easier plug connection and removal, whereas a locking cover is optionally available. Covers are offered in a variety of colors. The 30amp, 600 V trainlines feature an operating temperature range of -40° F to 140° F (-40°C to 60° C), a dielectric strength of 1000 V RMS, and 54 +/-10 lbs contact mating.
