Abstract
A method for establishing a predicted brake pipe pressure gradient is disclosed and generally includes installing an end-of-train unit on a railcar of an active train for sensing brake pipe pressure; installing a head-end-unit on a locomotive in the active train; transmitting brake pipe pressure data from the end-of-train unit to the head-end-unit; calculating predictive brake pipe pressure gradient between a first end of the brake pipe at the locomotive and a second end at the railcar; and displaying the predictive brake pipe pressure gradient for an observer in the locomotive.
