DEVELOPMENTS IN WAGON BOGIE DESIGN

Cast-steel bogie frames and bolsters are being used for goods stock on many railways. Basically, there are two designs, one employing springs without friction damping and the other, springs which are friction controlled. The bogies can be of either the plank or plankless type, but the self-aligning spring plankless type gives better riding qualities with consequent reduction of wear on bogie guides and on wheel flanges and rails. There is also a reduction in cost and weight due to the elimination of the plank. Friction controlled bogies have long travel bearing springs, although they can be designed for short travel springs, with adequate reserve travel and constant control of spring action. Tests have shown friction controlled bogies give improved riding of wagons at all speeds with consequent reduction in wear and maintenance. Unit brake beams are described.
