Abstract
It comprises a chassis (1) resting on at least one rail (3) by means of contact members (4, 4') connected to a vehicle (V) traversing the track. It comprises at least a detector (2) delivering an electric signal representing the distances separating a rectilinear reference space defined by the position in space of said chassis (1) and successive points on the surface of the rail line (3) traversed. The contact members of the chassis (1) with the rail (3) are constituted by two shoes (4, 4') articulated on the chassis (1) about axes (5) perpendicular to the longitudinal axis of the rail. The extent of these shoes (4, 4') in the longitudinal direction of the rail (3) is at least equal to twice the wavelength (l) of the undulatory deformations of the rail of short wavelength, but less than the wavelength (L) of the undulatory deformations of long wavelength.
