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.
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 ...
Rail inspection cars and HiRail trucks are the answer to today's high mileage inspection needs. The first rail inspection cars were created by Dr. Sperry. Since then, many new models have rolled out. These rail inspection cars are basically their own train with inspection equipment on board. The probes and transducers are mounted on carriages ...
Video / image inspection systems [ edit ] These systems rely on an array of video devices in various locations between the rails and either side of the track, looking for particular bogie components (such as brake beam, springs, friction wedges, etc) and this data is then put through image analysis to determine if there are maintenance issues.
As of 31 December 1994, Amtech had shipped over 3.1 million tags to railways in North America. The AAR reported that over 95% of the North American rail car fleet was tagged. Over 3,000 readers have been installed by the railways in North America as of the end of 2000. Amtech was bought by TransCore.
The other main activity for which specially designed Speno trains are used is measuring and inspecting railway tracks. With these trains the tracks can be inspected in "real time" while the train runs over the tracks: with video, infra-red recorders, acceleration equipment and other high-tech measuring tools the quality of the rails and points is monitored and recorded.
Founded in 2002, 10East's software as a service known as RailDOCS supports the signal and communications infrastructure needs of railroads in North America. [4] RailDOCS suite of applications provides railroads with tools to manage preventative maintenance, test and inspection, and configuration management for their signals.
A contract was let in 1972 to begin grading the route for the Railroad Test Track (RTT), a planned 14 mi (23 km) high-speed loop operating conventional rail vehicles up to 160 mph (260 km/h); within the high-speed loop, a Dynamics Track sub-loop 9.9 mi (15.9 km) long would investigate passenger and freight train dynamics at slower speeds.
