ABSTRACT:
An ultrasonic track testing carriage for movement along rails in operative relationship with a test vehicle is disclosed and includes a pair of wheel frames each having guide means for following the gauge side of the rail and ultrasonic sensing means mounted in working relationship with a portion of the rail for detecting changes in the rail and the position of the sensing means relative to the rail with a main frame disposed between the wheel frames and adapted to be coupled to the test vehicle for movement therewith. Interconnecting means extends between the main frame and each of the wheel frames so as to permit each wheel frame independent freedom of motion relative to the main frame in a plane substantially perpendicular to the gauge side of the rail while simultaneously maintaining parallelism between the wheel frames. The ultrasonic sensing means associated with each wheel frame is adapted to be adjusted in a vertical, lateral and angular plane relative to the rail being inspected.
