Abstract
A rail car truck has a pair of side frames, connected by a bolster, with the side frames each having pedestals at the opposite ends thereof which are designed to seat upon roller bearing adapters which are supported on the rail car truck wheel sets. Shear pads are positioned between each of the side frame pedestals and the corresponding roller bearing adapter. The shear pads include notches designed to interlock with projections on each side frame pedestal and notches designed to interlock with projections on each roller bearing adapter, whereby the shear pad is interlocked to both the side frame pedestal and the roller bearing adapter, preventing relative movement between the shear pad and the side frame pedestal and between the shear pad and roller bearing adapter in a direction parallel with the longitudinal dimension of the side frame.
