American freight service. 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.
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 high car detector is placed anywhere an excess height car could be misrouted onto a low clearance line. A shifted load detector is mainly found on railroads where double-stack trains are prevalent as the containers may become misaligned and present a hazard to bridge trusses or tunnel walls.
