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 ...
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.
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 ...
Sperry Rail Service (reporting mark SRSX) is a rail inspection company founded in 1928 by Elmer Ambrose Sperry. [1] The company was the first in the world to offer nondestructive testing of railroad tracks. Since its formation, Sperry has been contracted by most of the major railroads in North America to inspect rail. To accomplish this task ...
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.
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.
KarTrak, sometimes KarTrak ACI (Automatic Car Identification) or just ACI was a colored barcode system designed to automatically identify railcars and other rolling stock. KarTrak was made a requirement in North America in 1967, but technical problems led to the abandonment of the system by around 1977.
As a train comes through the portal the system captures between 700-1,000 pictures per car, giving a 360-degree image of each rail car to. AI is used to find defects.
