US 8,707,775 B2 · System and method for testing a rail car brake system

Abstract

A system for testing a rail car brake system includes a valve manifold having valves that selectively supply and vent test air to or from the brake system. A control circuit is operatively connected with the valve manifold and configured to operate in a first mode to automatically position the valves according to a prescribed test and to operate in a second mode to allow manual positioning of the valves. A method for testing a rail car brake system includes connecting test air to a valve manifold, connecting the valve manifold to the brake system, and testing the brake system using a control circuit configured to automatically position valves in the valve manifold according to a prescribed test. The method further detects a failed test result in the brake system and troubleshoots the brake system using the control circuit to manually position valves in the valve manifold.
