Claim 15:
16. A sensor device comprising:
an audio sensor configured to be mounted on a railroad vehicle, the audio sensor being configured to (i) monitor sounds emanating from one or more components of the railroad vehicle as the railroad vehicle moves along a track and (ii) generate sound data associated with the monitored sounds emanating from the one or more components;
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 non-anomaly sounds are removed from the filtered sound data;
compare the filtered sound data with known sounds to determine if an anomaly sound is present within the generated sound data; and

a wireless communication module configured to transmit an anomaly signal responsive to a determination that an anomaly sound is present within the generated sound data.
