The probes and transducers are mounted on carriages located underneath the inspection car. Modern-day inspection cars now use multiple NDT methods. Induction and ultrasound methods can be used in rail inspection cars and operate at testing speeds of more than 30 mph (48 km/h). Increased Camera systems for detection of broken joint bars or ...
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 ...
A train inspection system is one of various systems of inspection which are essential to maintain the safe running of rail transport. Because safety is of high importance when train cars move across the rails, there must be inspections. The cars are heavy and have moving parts that can break or become defective.

Sperry Rail Service Vehicle. Dr. Elmer Sperry began developing a method of locating internal rail defects in 1911. To build a railway test car, he contracted the American Railway Association in 1927. Construction on this first car began in June 1927. The body was metal-faced plywood, and was mounted on a Kalamazoo motor car bed. This car was ...

A railway track (CwthE and UIC terminology) or railroad track (NAmE), also known as permanent way (CwthE) [1] or "P Way" (BrE [2] and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade.
Bogie performance detectors can provide early detection of bogie defects, and early warning of derailment risks through flange climb or rail break. [5] Bogie performance detectors most often use optical methods, and are installed adjacent to the track with wheel sensors clamped to the rails.
