An electrical trainline junction box formed from a housing having first and second opposing sides, an identification module positioned in the housing, and first and second receptacles positioned in each of the first and second opposing sides. The first and second receptacles have a plurality of electrical contacts arranged in a predetermined geometry so that only one possible orientation and electrical connection to trainline flanges is possible. The flanges include contact pins in inserts coupled to the flanges by sleeves. The outer surface of the inserts and the inner surface of the sleeves are keyed to allow only a single orientation of the inserts relative to the sleeves. The outer surface of the sleeves is shaped to allow only a single orientation of the sleeves relative to the flanges, thus ensuring that the proper electrical connection is made when the junction box is installed.

A trainline integrity locomotive test device is provided that is configured to provide conventionally provided End-Of-Train (EOT) functionality required for a single locomotive test as well as functionality necessary for troubleshooting electrical problems in trainline electrical conductors, wherein the trainline integrity locomotive test device includes a reduced number of components in comparison with a conventional EOT device. Additionally, the test device is provided in more compact, durable and robust form relative to conventional EOT devices. As part of the transmission of trainline integrity data from the test device to the Head-End-Unit, a communications heartbeat signal is substituted for brake pipe pressure conventionally detected by EOT devices, so as to provide an indication of data communication reliability.
