Abstract
A snubbed railway car truck including a side frame having a bolster opening defined by a pair of columns. A bolster end is disposed in the bolster opening. Resiliently biased friction shoes are provided with friction faces which engage friction faces of wear plates mounted on the columns. Lands are provided on the bolster and the side frame columns along the opposite upstanding edges of the friction plate. The lands are provided with planar stops which engage during permisible relative turning between the side frame and bolster. The lands are inclined relative to the plane of the wear plate friction surface to prevent gouging during relative turning movement of the bolster and side frame.
