Abstract
A method for inspecting a rail vehicle includes receiving signals representative of temperatures of a wheel of the rail vehicle and generating a sensed wheel temperature profile of the wheel based on the signals. At least a portion of the sensed wheel temperature profile is representative of the temperatures of the wheel. The method also includes identifying waveform attributes in the sensed wheel temperature profile and designating the sensed wheel temperature profile as at least one of a typical wheel profile and an atypical wheel profile based on the waveform attributes in the sensed wheel temperature profile.
