Abstract: A system for testing trainline communications includes a command test box, a remote test box, and a controller. The command test box is coupled to a first electric coupler at a first end of a consist including one or more cars of a railroad train. The command test box applies a test signal to the first electric coupler and wirelessly transmits an indication of the test signal. The remote test box is coupled to a second electric coupler at a second end of the consist, and determines whether the test signal is present at the second electric coupler and wirelessly transmits an indication of the test signal. The controller communicates wirelessly with the test boxes to determine whether the test signal has successfully traversed the consist.
