Abstract
The present invention provides a single axle railway truck. An axle box with journal bearings is provided at each axle end. Each axle box includes a spring support from which two springs extend upwardly wherein their upper ends are received in spring retainers. The spring retainers extend from a lower surface of suppport beams and, accordingly, the support beams are themselves supported by the springs. A cylindrical dampening device has its lower end connected to the axle box and its upper end to a bracket extending outwardly from the support beam. A traction rod, or alternatively a shock absorber, extends from a side of the axle box to a mounting bracket near an end of the support beam.
