C & NW PINPOINTS ITS DERAILMENT PROBLEMS

Chicago & North Western is taking an electronic approach to the prevention of derailments by determining the precise locations where track conditions are conducive to rock-and-roll wheel uplift. The system measures track deviations in cross level and alignment and relates their combined effect in producing rock-and-roll action that will cause a car's wheels to lift from the rail at a critical speed. Pick-up device includes two gyroscopes, one sensitive to the roll axis of the axle and the other to the turn axis. Both are in fixed position with respect to the axle.
