Abstract: A railroad car retarder, adapted for installation in a classification yard or the like, and of the weight-compensating type, is so constructed as to reduce substantially the hydraulic requirements used for positioning the retarder. This is accomplished by operating four rock shafts simultaneously from a single source of power.

Abstract: A method and apparatus for improving the rollability of railroad cars moving into a classification yard or into the straight storage sections of the classification tracks of a classification yard; at least two wheels on each truck of each car are engaged by a guide rail which may be a part of a small retarder and which extends parallel to the track. The guide rail forces the wheels, and hence the truck, into alignment with the track. As applied to storage tracks, the track is preferably inclined, through the length encompassing the guide rail, at an angle sufficient to compensate for any loss of kinetic energy due to the limited braking effect of the guide rail.

Abstract: A retarder for installation in a railroad classification yard comprises a pair of retarder levers supporting retarder elements engageable with a car wheel. Noise is suppressed by modifying those elements. The levers are actuated by a cylinder assembly presenting opposed piston rods for applying actuating forces, and in order to eliminate any moment arm tending to bend the cylinder or piston rods, the cylinder is supported by a restrainer suspended from the traffic rail in the yard, provision being made for tangential contact between opposed surfaces of the cylinder assembly and the restrainer so that lines of force are constantly concentrated substantially at the axial center line of the cylinder assembly.
