A span bolster arrangement for interconnecting a pair of railway trucks and mounting a railway vehicle chassis, the span bolster arrangement including a span bolster structure having side members interconnected by lateral members and being mounted on and connected to a pair of railway trucks located beneath opposite ends thereof. The span bolster structure carries a plurality of elastic chassis support pads including primary load bearing pads and secondary stabilizing pads, which pads engage the underside of a vehicle chassis. The arrangement of the pads is such that axes of the pads intersect at a virtual point on a longitudinal central plane of the span bolster structure and approximately midway between the pair of trucks and at a height substantially corresponding to rail level.
