Other parameters, for exa

25、mple, acceleration and rail characteristics, also have an important role in contributing towards ride quality. Refer to annexes A and B for further information on these parameters. It comprises two informative annexes (annex A and annex B). This European Standard is one of the series EN 13848 “Railw

28、are described in !Part 2“ of the standard. This European Standard applies to all track geometry parameters including track gauge, longitudinal level, alignment, cross level (cant / superelevation) and twist. It defines each parameter and specifies the requirements for measurement, the analysis metho

29、ds and the presentation of results. !Parts 3 and 4 give a description of measuring devices complying partially with this Part 1 according to the specificities of respectively track construction and maintenance machines, and manual and lightweight devices.“ 2 Normative references This European Standa
