The friction brake system components described herein were developed on behalf of the United States Department of Transportation for the Advanced Concept Train I (ACT I), a 220-passenger rapid transit rail vehicle. The choice of chrome copper as disc material and disc-associated friction lining was made to meet the severe friction-brakes-only operating mode and utilises the high friction coefficient and diffusivity of chrome copper. Results from dynamometer tests and from a limited programme of rail trials, corresponded well with predictions contained in the thermal analysis. Braking rates were maintained and occasionally exceeded during simulated round trip tests at disc surface temperatures to 850 K.
