ABSTRACT OF DISCLOSURE This invention relates to railway vehicles of the kind having at least two wheel-sets, each with a live axle mounted in a respective pair of axle bearings, at least one axle bearing of one wheel-set being elastically interconnected with at least one axle bearing of the other wheel-set through bracing means providing bracing between the wheel-sets. According to one aspect of the invention said bracing means comprise a frame structure for each wheel-set which extends transversely of the vehicle and is rigidly connected between axle boxes housing said axle bearings of its respective wheel- set, said frame structures being shaped and arranged so as to be connected together by said elastic connection at a level, which is below the axle height of the vehicle. Preferably said elastic connection is at a level well below said axle height, and a bolster is located within the space so provided. According to another aspect of the invention, the vehicle has side frames connected to respective axle boxes via a primary spring mounting and is characterised in that each said side frame is of fabricated construction comprising a bridge member of I-section from which a sub-frame depends, said bridge member and sub-frame defining a space therebetween into which respective side flanges of a bolster project, each said side flange being supported by the respective sub-frame via a secondary spring mounting. According to a further aspect of the invention, each said axle box is fabricated to provide a bearing support surface which is semi-circular or less, for supporting a cartridge bearing, and the cartridge bearing is rigidly fixed in position by a part-circular strap appropriately fixed on the axle box and tightened down onto said cartridge bearing.
