ABSTRACT:
A railroad car (12) has a set (B1) of brakes acting on wheels (W1) at one end of the car and a set (B2) of brakes acting on wheels (W2) at the opposite end of the car. A mechanism (38) for applying a brake force produced by operation of a hand brake (HB) includes a force splitter (40) interconnected with the hand brake and one set (B1) of wheels to transmit the brake force to this set of brakes. A first torque unit (54) is interconnected with the force splitter to transfer the brake force from one end of the car to the other. A second torque unit (74) is interconnected with the first torque unit and the other set (B2) of brakes to transmit the brake force to this other set of brakes. Application of both sets of brakes in response to operation of the hand brake prevents movement of the car.
