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.

Measuring method of at least one geometrical characteristic of the transverse profile of the head of at least one rail of a railway track having two parallel lines of rails, comprising determining a reference base perpendicular to the axis of the track and parallel to a tangent line to the rolling surfaces of the two lines of rails; determining the distances separating at least two longitudinal side lines of the tracing of the head of a rail from said reference base; and calculating from these distances at least one characteristic of the actual transverse profile of the head as a function of its position with respect to the other line of rails. Device for the measurement of at least one characteristic of the transverse profile of the head of at least one rail of a railway track having two parallel lines of rails, comprising a measuring carriage resting laterally and vertically against the two lines of rails of a railway track defining a reference base perpendicular to the longitudinal axis of the track and parallel to a tangent line to the rolling planes of the two lines of rails; at least two detectors delivering signals representative of distances separating at least two longitudinal side lines of the tracing of the head of a rail from the reference base; and an electronic device comprising a calculating unit determining by the signals delivered by the detectors a characteristic of the actual transverse profile of the rail as a function of its position with respect to the other line of rails.
