A track inspection car supported on railroad track by flanged wheels mounted on a truck, and having means for engaging a tractor-truck at one end and wheels with highway tires at the other. The wheels are relatively vertically displaceable by selectively inflating pneumatic springs for converting the car from on-track operation to an off-track trailer-truck configuration. A pair of ultrasonic sensor probes are mounted on the wheel truck coupled to a computer in the car. The car also includes an on-track driving motor, a driver station, a computer operators station, an observer\s station, and a water supply for creating a fluid acoustical coupling between the sensors and the rails.
