ABSTRACT:
A test device and a method of testing leakage of a brake cylinder on a railroad car having a brake pipe and brake valve. The method includes charging the brake pipe, discharging the brake pipe at least at a service rate to actuate the brakes by charging the brake cylinder and simultaneously with charging the brake cylinder charging a reference volume to the brake cylinder pressure. Discharging of the brake pipe is terminated and the pressure in the reference volume is maintained. The difference of pressure between the brake cylinder and the reference volume, at a fixed period after the beginning of maintaining the pressure in the reference volume, is measured to determine the leakage.
