Recently we unloaded a 1994 BN covered hopper at the grain terminal. What made this car unusual was the electrical cables which ran the length of the car,with the cables ending at connecting jacks at the car's ends.One cable appeared to be fastened to a sensor on a brake beam.First time we saw such a device. What was it's purpose ? All I can surmise is it sent a signal when the brakes were on or off. Any other thoughts ? Joe
