Abstract

See full text

An apparatus for inspecting a railroad track may include a first sensor, a second sensor, and a controller. The first sensor may detect a first signal while the second sensor may detect a second signal. The first signal may correspond to a response of the railroad track, at a first location on the railroad track, to a motion of a rail car wheel on the railroad track. The second signal may correspond to the response of the railroad track, at a second location on the railroad track, to the motion of the rail car wheel on the railroad track. The controller may generate, based on the first signal and the second signal, a transfer function corresponding to the response of the railroad track at the second location to stimuli applied at the first location. Defects in the railroad track may be detected by analyzing the transfer function.
