battery electric vehicle
A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that exclusively uses chemical energy stored in rechargeable battery packs, ...
developed in response to zero emission
rail car requirements in certain environments. It was created in the hopes to replace the RRV Hi-Rail type
road-rail vehicle that is used for ultrasonic rail flaw detection as well as non-zero emission trolleys that do not have full
rail inspection
Rail inspection is the practice of examining rail tracks for flaws that could lead to catastrophic failures. According to the United States Federal Railroad Administration Office of Safety Analysis, track defects are the second leading cause of ...

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.
