A drive and axle assembly is disclosed for a railway vehicle, the assembly comprising two side frames (5) parallel to one another and an axle (2a) mounted horizontally between the side frames in a manner which allows the axle to move both vertically and in a fore-and-aft direction. Ends of the axle have respective flycranks (6a). A crankshaft is mounted horizontally and substantially parallel to the first axle between the two side frames and ends of the crankshaft have respective cranks (6d) each arranged in an in-phase relationship with the corresponding flycrank (6a) of the adjacent end of the axle (2a). Coupling rods (8a) fixed to the respective crankshaft cranks and the adjacent axle flycranks ensure that rotation of the crankshaft causes rotation of the axle. At least one tie rod (12a) couples the axle to the crankshaft such that the lateral distance between the crankshaft and the axle remains constant.
