ABSTRACT OF THE DISCLOSURE: Apparatus for measuring the undulatory deformations of the rolling surface of railroad rails, comprising a chassis resting on at least one rail by means of contact members connected to a vehicle traversing the track. The apparatus further comprises at least a detector delivering an electric signal representing the distances separating a rectilinear reference base defined by the position in space of said chassis and successive points on the surface of the rail line traversed. The contact members of the chassis with the rail are constituted by two shoes articulated on the chassis about axes perpendicular to the longitudinal axis of the rail. The extent of these shoes in the longitudinal direction of the rail is at least equal to twice the wavelength of the undulatory deformations of the rail of short wavelength, but less than the wavelength of the undulatory deformations of long wavelength.
