Abstract
An improved railway car retarder, fitted with fluid power cylinders, such as hydraulic or pneumatic cylinders. The cylinders function to temporarily release the force of retarder friction rails on train car wheels. The retardation function is still carried out by conventional spring assemblies and the functional integrity of existing retarders is not disrupted.
