An articulated railway vehicle includes a truck having at least two wheeled axles, a truck frame supported on the axles, pairs of transversely spaced upright springs centered longitudinally of the truck and supported on the truck frame, a pair of body units aligned longitudinally of the truck and spaced apart longitudinally of the truck, elements projecting longitudinally from one of the body units and spaced apart transversely of the truck corresponding to the outer pair of springs and seated respectively thereon, and additional elements projecting longitudinally from the other body units and spaced apart transversely of the truck corresponding to the inner pair of springs and seated respectively thereon, the springs being distortable in shear generally longitudinally of the truck to accommodate relative swivel between the car bodies with each other and the truck, and transversely of the truck to cushion lateral forces. The bodies are connected to each other by a pivot structure above the center of the truck, which is connected to the truck frame to transmit longitudinal forces therebetween while accommodating relative swivel, transverse and vertical movements of the bodies with respect to the truck frame as are permitted by the springs.
