ABSTRACT:
A system and method for inspecting railroad track is disclosed. The disclosed system includes lasers, cameras, and a processor. The lasers are positioned adjacent the track. The laser emits a beam of light across the railroad track, and the camera captures images of the railroad track having the beam of light emitted thereon. The processor formats the images so that they can be analyzed to determine various measurable aspects of the railroad track. The disclosed system can include a GPS receiver or a distance device for determining location data. The measurable aspects that can be determined by the disclosed system include but are not limited to the spacing between crossties, the angle of ties with respect to rail, cracks and defects in surface of ties, missing fastener components, misaligned fastener components, sunken tie plates, raised spikes, rail wear, gage of rail, ballast height relative to ties, size of ballast stones, and break or separation in the rail. The system includes one or more algorithms for determining these measurable aspects of the railroad track.
