scope:

NEN-EN 13848-6 characterises the quality of track geometry based on parameters defined in EN 13848-1 and specifies the different track geometry classes which have to be considered. This European Standard covers the following topics: - description of track geometry quality; - classification of track quality according to track geometry parameters; - considerations on how this classification can be used. This Standard applies to high-speed and conventional lines of 1435 mm and wider gauge railways provided that the vehicles operated on those lines comply with EN 14363 and other vehicle safety standards. This Standard forms an integral part of EN 13848 series.
