ABSTRACT:
To measure undulatory wear of the rails, a carriage moving along a railroad track has three measuring bases formed by girders each supported on two rollers and each having a rail sensor providing a measurement of deformation of the rail intermediate the support rollers defining the respective measuring base. The measuring bases have different lengths to provide measurements of the amplitude of undulations of given wavelength values. The length of each successively shorter measuring base is related to the length(s) of the longer one(s) to include amplitude measurements for wavelength values not provided by the longer measuring base(s).
