ABSTRACT:
A device for testing an air brake system of a locomotive, an air brake system having a compressed air source, a conduit for the ingress and egress of compressed air and a brake valve which is communicatively connected to both the compressed air source and the ingress/egress conduit. The device is particularly for testing the functionality of the brake valve of the air brake system. The testing device includes a trackside stand for placement in proximity to a locomotive servicing site, and a storage reservoir for holding a predetermined volume of compressed air. The trackside stand is further comprised of a conduit having one end for communicative connection to the storage reservoir and an opposite end for communicative connection to the ingress and egress conduit of the locomotive air brake system. Subsequent to the interconnection of the testing device to a locomotive air brake system, the various integrated functions of the brake valve can be tested by directing predetermined volumes of compressed air to and from the brake valve. The testing device also includes an air pressure testing gauge to determine the accuracy of the air pressure gauges of the locomotive air brake system, and an arrangement of pipe and testing conduits and shutoff valves permits one storage reservoir to be utilized in conjunction with a plurality of trackside stands.
