Abstract

Measuring method and system by laser diastimeter of shiftings of the long welded rail in operation constrained to the track sleepers and under construction free from the track sleepers. The method allows only one person for carrying out all of the check operations provided by the LWR rules in operation and under construction with automatic filling of the suitable check forms.
