Product Overview

480V Trainline Connectors

Cadillac® brand of 480V jumpers and receptacles provide head end power (HEP) to locomotive hauled passenger rail cars. Our jumpers feature integrally molded plugs and receptacles that protect the contacts from condensation, dust and debris, and can also use power from a power car or wayside ground based source. The receptacle skirt features a patented, integrally molded, expandable stabilizer to eliminate insertion problems often encountered in connectors with glued support rings. This design reinforces the front of the connector head.
