An electromagnetic straight air brake equipment, especially to an air brake command system for railway vehicles for controlling the brake pipe pressure by employing an electric brake command type brake controller and electropneumatic convertor valve arrangement. This invention makes it possible to assemble the brake controller and the master controller into one handle, and requires no pneumatic piping leading to the operator's cab since the pneumatic apparatus is all located beneath the floor of the railway vehicle.

Straight air brake control system

An electropneumatic master controller for an electromagnetic straight air brake system for railway vehicles has a brake valve, brake solenoid valve, a release solenoid valve, and an electrical interface circuit. The electrical interface circuit includes a first and a second sensor and a first and a second comparator which are responsive to the pressure of the control line and straight air line to open and close the brake and release solenoid valves for applying and releasing the brake cylinder.
