Abstract

A track brake control system for providing braking of a railway vehicle is disclosed. The control system operates upon receipt of an emergency braking command. The control system includes a member for receiving deceleration information from one or more sensing devices. The control system further includes member for comparing the deceleration information with a reference value or reference profile. Further, the control system includes at feast one regulating device for continuously adjusting a braking demand signal to a track brake so as to cause deceleration of the railway vehicle based on the this comparison.
