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 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 “Railway applications/Track - Track geometry quality” as
listed below:
 Part 1 : Characterization of track geometry
 Part 2 : Measuring devices - Track recording vehicles
 Part 3 : Specification for measuring devices - Devices fitted on track maintenance machine
 Part 4 : Specification for measuring devices - Track measuring trolleys and manually operated devices
 Part 5 : Geometric quality assessment

1 Scope
This Part of this European Standard specifies the requirements for the homologation of track geometry quality
parameters as measured by various measuring devices. These measuring devices are described in Parts 2, 3, 4 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 methods and the presentation of results.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies. (including amendments).
