(Case No. 7032) ABSTRACT OF THE DISCLOSURE A low-profile railway car retarder having a pair of braking bars disposed parallel and on opposite sides of a track rail and having an upper and lower pivotal lever carrying a respective one of the pairs of braking bars. A pneumatic motor pivotally connected to the outer extremi- ties of the upper and lower levers, and the height of the pivotal connection of the upper lever is substantially at the same level as the track rail so that a humped railway vehicle is permitted to freely pass through the car retarder. The pneumatic motor lifts the upper lever and depresses the lower lever to move the pair of braking bars to a closed braking position wherein pressure is supplied to the pneu- matic motor so that the pair of braking bars engage the opposite side of the wheels of a traversing vehicle at a relatively high point to exert a greater amount of retarda- tion of the vehicle.
