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.
This most likely will be done with laser-optical transmitting transducers in ultrasonic testing. Eliminating contact with the rail could one day allow high-speed detection of flaws. (Testing of rail is currently able to be done at 80 km per hour with a Speno US-6 Ultrasonics train) Another need for the future is a complete rail inspection system.
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 ...
These systems are initially calibrated to a particular ‘neutral state’ by measuring the rail with neutral compression (no pulling or pushing) and an agreed neutral ambient temperature. The system then measures the rail to detect if these parameters get too far from neutral state, and will alert if the rail is approaching a breach of ...
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 ...
These rail parts had to be examined individually by a hand-held ultrasonic scanner. The induction system was augmented by mobile semi-automated ultrasonic inspection equipment in 1960. Today, Sperry performs both induction testing and ultrasonic testing with its rail service vehicles. [2]
For inspection purposes, modern catenary maintenance vehicles often include computers and software that can analyze and store data on catenary conditions. Amtrak's Plasser MTW 100 Catenary Inspection and Maintenance Car includes a catenary wire measuring system which is capable of storing data on catenary conditions for up to 100 miles of track ...
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.
