Abstract

A hot box detector system is provided in which an infra-red scanner (16) is arranged to scan the wheel bearings of railway rolling stock passing over a section of track (10) and to generate signals which are processed to determine the temperature of the bearing, the nature of the bearing, and, for signals derived from bearings within a closed housing (24, 26), to determine if the scanned surface of the housing is an inner sidewall (32, 34) or an outer sidewall (36, 38) of the housing (24, 26) relative to the bogie (22) to which the bearing belongs. Train speed is also determined from wheel detectors 12, 14. The signals are then normalised to account for differences in the heat dissipating characteristics of the inner outer sidewalls, and the air stream cooling resulting from the movement of the train before being analyzed to determined whether or not the bearing is overheated. <IMAGE>
