Abstract
A low-profile railway car retarder system comprising a fulcrum pin, an upper and a lower lever, and two braking assemblies, is disclosed. The levers are located beneath a horizontal plan drawn from the top of the rail, thereby preventing inadvertent contact with a passing car. The braking actuator comprises an air-tight bladder which is filled with fluid or drained of fluid to cause the frictional braking members to move between closed and opened braking positions, and provides greater control than prior art systems.
