Rail Inspection

Ultimate Flaw Detection services

Q Rail NDT inspection group offers a comprehensive range of flaw detection services by experienced personnel, qualified to US & European standards.

Rail flaw detection, for over two decades, has become a major part of our services to several European, South American, US and others around the world. Quantum has a sophisticated rapid twin rail (Track) surface, volumetric inspection for both Vignola and groove rail type (Ri59, etc.).

Our rail integrity evaluation uses various testing machines in accordance with UIC and the European standards, EN ISO 16729 Pts 1 and 3 (Rails UT, and ET).

Our automated and intelligent system rail flaw detection and analysis provides fast, reliable, accurate, certified inspection services & permanent data storage.

Members of our Industry Advisory include:

Exclusively presenting a state-of-the-art intelligent rail inspection system, with which Quantum rail has provided many valuable and second-to-none services to the Rail industry in Europe.Rail bound Jeep type vehicle RTI 8000SX system with faster processing capabilities and ROM transducers is ideal for the evaluation of Rolling Contact Fatigue Cracks (RCF). The probes configurations are unique for interrogation of Thermic, Flash Butt and other types of rail welds. This Rail NDT rail flaw detection vehicle provides detailed rail weld inspection, compound fissure type defects, bolt-hole cracks, RCF location and evaluation, squats & Wheel-burns at speeds of 30 miles per hour; making it the fastest and most reliable rail flaw maintenance system management.

Setting the latest innovation

A Game Changer: RET Walking Stick


Q Rail NDT has developed the first RET walking stick in the UK. Q Rail NDT has developed, designed and manufactured its innovative QuRET, in conjunction with Ether NDE flaw detection unit. It has successfully carried out a series of RCF/head checks and GCC evaluations with remarkable accuracies, consistencies and detection speed. QuRET, can detect complicated defects in one pass of the railhead using WideScan© Rail probe that has been characterized using artificial flaws of different sizes, orientation and probe-to-rail-clearance. The test rail contains 9 EDM notches, machined on the gauge side at between 18˚ to 22˚ to the vertical, simulating a series of RCFs with varying depths of: 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0 mm. This will be used to determine sensitivity levels that may be achieved using this probe. The active face of the probe, with an 80 mm scan width, can easily be contoured to suit different railhead profiles.
