ABSTRACT:
A measuring carriage (2,4,6), defining a transverse reference base extending parallel to the plane of the railway track, intended to be connected to a driving vehicle. This carriage comprises three detectors (13, 14, 15) located above and transversely to each line of rails (5) in order to cover a portion of the tracing of the rolling table. These detectors (13,14,15) are connected to an electronic processing circuit (16 to 23, 29) of their signals adapted to determine the amount of curvature (f) of the rolling table and its inclination (i) with respect to the plane of the railway track with the measurements representing the distances (Ya, Yb, Yc) between the reference base and the rolling table under the detectors.
