A testing device for conducting the Initial Terminal Inspection of the air brake system of a made-up train includes a first valve assembly for at least charging and applying the brakes through the test device operable from the location at which the device is coupled between the train brake pipe and a supply of compressed air, and it also includes a second valve assembly for releasing the brakes actuated by receipt of a remotely-transmitted signal. The Initial Terminal Inspection requires that the brakes of a train be inspected in both their applied and their released positions. A testing device is normally connected to the train brake pipe at the locomotive end. The inspection of the brakes in their applied position requires the inspector to walk the length of the train, usually from the locomotive end to the far end of the train. This can be a distance of a half mile or a mile or more. When the inspector reaches the far end of the train, completing the inspection of the brakes in their applied positions, the release of the brakes can be triggered by transmitting a signal to the second valve assembly from the inspector's remote location at the end of the train. The signal is received by the second valve assembly, for instance at a solenoid valve within the second valve assembly. Upon this release of the brakes, the inspector returns to the locomotive end of the train, inspecting the brakes along the route.

An integrally cast bearing adapter arrangement is provided in the pedestal of a railcar truck side frame, which side frame is cast with a pedestal jaw having a roof, and vertical walls of a first and second leg which roof and walls operate as a bearing adapter to receive a bearing assembly for an axle end without introducing the manufacturing and assembly tolerances from discrete component assemblies, thereby avoiding the lateral displacement associated with the added tolerances and operating to minimize angular displacement between each mated axle and side frame.

Railcar truck bearing adapter construction

A railcar truck side frame has a pedestal jaw arrangement, which inclines the bearing adapter for the axle and bearing assembly with a relative slope in the side-frame longitudinal direction, to provide transfer of the forces causing angular displacement of the axle to stop lugs on the side-frame outer surface and to minimize axle angular displacement and, consequently, truck warping and hunting.

A railway vehicle bolster having an air brake system air reservoir formed integrally in a cavity defined by a top web and side walls of said bolster by enclosing the cavity with end walls and a bottom wall. Air inlet and outlet means provide communication between the air brake system and the reservoir.

A railway coupler yoke assembly is provided. A yoke, draft gear and follower are assembled as a unit assembly and maintained as such by the installation of bands at various locations about the assembly. Such yoke assembly can then be shipped and stored as an assembly until the time of installation in a railway car. At such time, the bands are cut and the assembly is placed in the railway car.
