This document specifies the minimum requirements for measuring systems fitted on track construction and maintenance machines to give an evaluation of track geometry quality when they measure any one or several of the parameters described in EN 13848-1.
This document also gives the acceptable differences from EN 13848-1 when using chord measurements.
This document does not specify:
