Claim 0:
1. A sensor device comprising:
a housing configured to be mounted on a first railroad vehicle;
an audio sensor coupled to the housing and being configured to (i) monitor sounds emanating from one or more wheels of the first railroad vehicle as the first railroad vehicle moves along a track and (ii) generate sound data associated therewith;
a CPU configured to:
generate, based on audio signatures included in the sound data, filtered sound data, wherein portions of the sound data having audio signatures associated with track sounds are removed from the filtered sound data;
compare the filtered sound data with known wheel sounds to determine if a wheel anomaly sound is present within the generated sound data; and

a transmitter configured to transmit a wheel anomaly signal responsive to a determination by the CPU that a portion of the generated sound data is indicative that a first one of the one or more wheels has a wheel anomaly.
