Abstract
A rail car truck includes a pair of longitudinally spaced wheelsets, a pair of laterally spaced side frames extending between and supported by the wheelsets and a bolster which extends between the side frames to support a vehicle body. There is a brace connected between the side frames to control relative longitudinal movement therebetween. The brace includes a center clamp assembly located generally intermediate the side frames and generally mid-way between the wheelsets. Each side frame mounts a pair of longitudinally spaced end blocks. There are four struts, each being inclined to the longitudinal axis of the truck and each extending from and being connected to an end block and to the clamp assembly.
