Sperry Rail Service is a company contracted by most of the major railroads in North America to inspect rail. The rail flaw detector car was invented by Dr. Elmer A. Sperry. To railways and railfans, Sperry's name is most likely associated with the Sperry Rail Detector car. 


A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the crosslevel of the two rails. The cars use a variety of sensors, measuring systems, and data management systems to create a profile of the track being inspected.
