Abstract
A portable, single-car test unit for a railway freight brake control valve for manually executing pressure manipulations to evaluate tree operating conditions of the control valve. The pipe bracket portion is connected to a brake pipe, an auxiliary reservoir, an emergency reservoir, a brake cylinder retaining valve and a brake cylinder each being connected to a respective fluid passageway. The test unit accesses the fluid passageways at access ports, respectively connected to each passageway. Valves are utilized in the test unit to manipulate the pressure in the fluid passageways and pressure gauges measure fluid pressure in the passageways. An operator records each pressure measurement and calculates and stores the differences between selected pairs of the pressure measurements as well as elapsed time data for the measurements.
