Investigation into the changes in adhesion between a sliding wheelset and rail during braking (with a view to specifying the required performance of the P train HK brakes) (IM-PS-174)

A previous memorandum (Reference 1) described in detail how the wheelslide activity during braking of APT-E has been monitored on a continuous basis by recording brake torque and wheelset speed for the six hydrokinetically braked axles of the train. The report also gives details of the way in which this...
