ABSTRACT:
A hydraulic braking system for a rail car is provided. The system includes a hydraulic pump or motor adapted to engage a rail car axle or wheel. When rotating, the axle or wheel drives the hydraulic pump causing a hydraulic fluid to circulate. By restricting the flow of fluid to the pump, a braking force can be applied to the axle for slowing and stopping the rail car. Various programmable electronic controls can be added to the braking system for allowing control at a central location.
