A detector apparatus uses two scanners on the right of way for monitoring the wheels of a moving train . The scanners scan the wheels transversely to the tracks along a common axis and generate wheel temperature signals. The signals corresponding to the wheel bearing end caps or housing lids indicative of the wheel bearing temperatures are separated and analyzed so that the apparatus can detect and indicate both hot wheel and hot bearing conditions.

Infrared hot bearing and hot wheel detector

A hot box detector system is provided wherein heat signals from bearings within a housing are analyzed to determine if the scanned surface of the housing is an inner sidewall surface or an outer sidewall surface. The signals are normalized to account for differences in the heat dissipating characteristics of the inner and outer sidewalls and air stream cooling resulting from the trains movement.
