Systems for retarding the speed of a railcar comprise: a brake; a hydraulic actuator moving the brake between a closed position in which the brake applies braking pressure on a wheel of the railcar and an open position in which the brake does not apply braking pressure on the wheel of the rail car; a hydraulic circuit comprising a first manifold and a second manifold; a pump configured to pump hydraulic fluid into at least one of the first manifold and the second manifold; and a logic element controlling pressure of the fluid in the first manifold such that when the wheel enters the brake and forces the brake towards the open position. The logic element reacts to maintain a selected pressure in the first manifold, thus causing a selected braking pressure to be applied by the brake on the wheel of the railcar.
