ABSTRACT:
A redundant sensor system for predicting railway hazards including breaks in each rail, the location of the breaks, and determining when a railway vehicle has a flat wheel. Vibration sensors are distributed along both rails of a railway. Each sensor has a detection band at least within the sensing range of adjacent sensors and it is positioned such that the sensor detects vibration in both the horizontal and vertical axis of the rail. A central processor evaluates the data from these sensors and identifies the rail break, the location of the break, and the flat wheel.
