Abstract (en)
[origin: EP0418522A1] The track is divided into successive sections starting from a start point and for each of these sections and for each line of rails the wavelengths and/or amplitudes of the longitudinal undulations of the tread of the rail are measured and the transverse profile of the rail head is measured. A reference profile is then compared with the measured transverse profile and the transverse cross-section of metal to be removed in order to correct the transverse profile of the rail is determined, then the longitudinal cross-section of metal to be removed in order to correct the longitudinal profile of the rail is determined as a function of the amplitudes of the longitudinal undulations of the rail. The total cross-section of metal to be removed is determined and as a function of a working speed, of the metal removing characteristics of the tools and, as a function of this total cross-section of metal to be removed, the minimum number of tool passes necessary is determined.
