Cast iron block braking of class 150 wheel : comparison of single clasp & tandem pusher arrangements (TM-PBS-097)

The comparative frictional behaviour of high phosphorus (P30) brake blocks in the tandem pusher (UIC 250 mm x 2) arrangement and the single clasp (BR 'R2') arrangement is described. Results were broadly similar, both arrangements having a large scatter in friction values over the various conditions tested, with a minimum...
