24、+A1:2008 (E)5 Introduction This European Standard defines the minimum requirements for the principal track geometric parameters that characterise track geometry quality. Other parameters, for example, acceleration and rail characteristics, also have an important role in contributing towards ride qua
25、lity. 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 “Railway applications/Track - Track geometry quality” as listed below: Part 1 : Characterization of track geome

27、 Standard specifies the requirements for the homologation of track geometry quality parameters as measured by various measuring devices fitted on track recording vehicles.“ These measuring devices are described in !Part 2“ of the standard. This European Standard applies to all track geometry paramet
28、ers including track gauge, longitudinal level, alignment, cross level (cant / superelevation) and twist. It defines each parameter and specifies the requirements for measurement, the analysis methods and the presentation of results. !Parts 3 and 4 give a description of measuring devices complying pa
