Abstract
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.
