Abstract
A pipe bracket for use in a freight brake control valve on a railway freight vehicle is provided. Four access ports are preferably provided on a first side of the pipe bracket. The freight car piping, including a brake pipe, brake cylinder line, emergency reservoir line and an auxiliary reservoir line are connected to a second side of the pipe bracket. The freight brake control valve further includes an service portion coupled with a third side of the pipe bracket and an emergency portion coupled with a fourth side of the pipe bracket. A plurality of passageways are included within the pipe bracket for providing fluid communication from the freight car piping to the service portion and the emergency portion. The access ports are preferably connected to each of the passageways within the pipe bracket to permit testing of the fluid pressures within the passageways.
