Ground-breaking milestone in wheel inspection technology
The Nordco Wayside Cracked Wheel Detection System represents a milestone in the railroad industry. Responding to the safety and economic concerns related to broken wheels, the American Association of Railroads (AAR) initiated a research program with the Transportation Technology Center (TTCI) for detecting cracks in railroad freight car wheels using ultrasonic methods. Developed in partnership with TTCI, and first installed at a key Union Pacific yard in Nebraska, the Wayside Cracked Wheel Detection System is the first wayside wheel inspection system that directly mitigates the risks and costs associated with internal wheel defects. This exciting new system has been featured in:

Real-time assessment of wheel flaws
The Wayside Cracked Wheel Detection System consists of four inspection stations per rail, with one ultrasonic test head per station (for a total of eight test heads).
As the car passes over the inspection stations on flange-bearing track, the system sprays couplant onto the lower surface of the rail wheel using a fine mist. The inspection probes assess the integrity of the wheels as they pass through the inspection stations at speeds up to 5 mph (8 km/h). Each inspection station inspects one wheel in a four-wheel sequence, so that the workload is spread and equalized over the entire system, minimizing the risk for individual inspection station failure.
The system then provides real-time assessment and reporting of flaw types, flaw sizes, and flaw locations that appear in and across the tread and rim of the wheel.
