GRAVEL FIT TO TRAVEL

An infra red scanning system that can locate worn out sections of railway track bed, and which can be installed under ordinary trains, is described. The system works by measuring the temperature of the ballast during the night and differences as small as 0.1 degrees C can be detected. Degraded ballast is measurably cooler than undegraded ballast. The system can be used to prioritise maintenance schedules.
