A system for retarding the speed of a railcar comprises a brake; a hydraulic actuator moving the brake between a closed position in which the brake applies braking pressure on the wheel of a railcar, and an open position in which the brake does not apply braking pressure on the wheel of the railcar; a hydraulic circuit provided with a pump arrangement for supplying hydraulic fluid to the hydraulic actuator; and a control circuit coupled to the hydraulic circuit for controlling the flow of hydraulic fluid to move the brake between the closed and open positions.

Systems for retarding the speed of a railcar

Devices, a system and a method for controlling travel of a railcar along a set of rails are provided, the railcar having wheel treads that ride on the rails. A railcar stop is selectively movable between a first position wherein the railcar is free to travel along the rails, and a second position wherein the railcar stop is configured to engage the tread of the at least one of the wheels to thereby stop and prevent travel of the railcar in at least a first direction along the rails. The railcar stop is further configured to be selectively movable in the first direction along the rails from the second position to a third position to thereby disengage the railcar stop from the tread of the least one of the wheels.
