A train inspection system is one of various systems of inspection which are essential to maintain the safe running of rail transport.

In 1919, the Signaling Club became the Signal Division of the newly created American Railway Association (ARA) and the Telegraph Superintendents became its Telegraph and Telephone Section.
A hirail vehicle used by Sperry Rail Service to inspect tracks for defects. Robust inspections are key to a safe railroad and discovering flaws and wear in tracks early enough that they can be addressed before causing a derailment, or becoming so severe that the work must be done immediately, regardless of whether it is a convenient time to do so.
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 ...
Since the 1990s, Loram has also been offering rail inspection services. Loram adapts commercial consumer vehicles for use on rails, and has developed a computerized, laser inspection system which compares the rail to a pre-determined profile in order to identify damage. Each rail is identified using its Differential GPS location. The rail ...
