Abstract:
An apparatus and method for inspecting a rail joint bar transported along a railway rail by an inspection vehicle is provided. The apparatus and method includes a pair of ultrasonic transducers housed in liquid-filled wheels. The wheels are positionable for a stored position to a measurement position in rolling contact with the vehicle surfaces of the rail joint bars on each side of the rail. The ultrasonic transducer transmits a signal into the rail joint bar and the reflected signal is detected by the transducer and analyzed to identify flaws in the rail joint bar.
