Abstract
A single car test device includes a housing; a source port, on the housing, to be connected to a source of pressurized air; a brake pipe port, on the housing, to be connected to the brake pipe connector; and valves, in the housing, selectively interconnecting the ports to each other and atmosphere to perform tests. A brake cylinder sensor is to be connected to a brake cylinder tap. A sensor module on an interface device, remote from the housing, is to be mounted on the test ports on a control valve for determining pressure at the test ports. A controller is connected to the valves, the sensor module and the brake cylinder sensor and includes a program performing a plurality of component tests which form a single car test. The interface device includes reservoir charging valves controlled by the controller.
