ultrasonic rail flaw detection.
A newly developed alternative is the HANDWave DRT (Dual Rail Tester). It is capable of performing ultrasonic rail flaw detection equivalent to current rail bound testers, and can be separated into two separate Single Rail Testers (HANDWave SRT) or towed behind a rail vehicle.
