Abstract:
A thermal sensor composed of a standard bolt which has been modified to embody a temperature sensing element and placed into a bearing assembly of a train. This element contains a heat-sensitive wax that at a preset temperature expands causing the motion of a piston which exposes projections. The projection may function as an antenna either passive (reflective) or active (transmitter) that can be probed from the wayside with very high selectivity.
