1. An apparatus for detecting a temperature range of a railroad train wheel or bearing wherein infrared radiation radiating from the wheel or bearing of a train traversing a railroad track is indicative of a temperature range of the wheel or bearing, the apparatus comprising:

  • a sensor for sensing infrared radiation radiating from the wheel or bearing within two or more infrared wavelength ranges and generating signals indicative of the sensed infrared radiation in each of the wavelength ranges; and

    a processor determining a temperature range of the wheel or bearing from the generated signals.
