Railway applications - Track - Track geometry quality - Part 1: Characterisation of track geometry
This EN specifies the requirements for homologation of track geometry quality parameters as measured by recording vehicles and by manually operated devices. The standard applies to all relevant track geometry parameters including track gauge, longitudinal level, alignment, cross-level (cant/superelevation) and twist. It does not however deal with conicity or railhead profile matters. It defines each parameter and specifies the requirements for measurement, the analysis methods and the presentation of results.
Bahnanwendungen - Oberbau - Qualität der Gleisgeometrie - Teil 1: Beschreibung der Gleisgeometrie
Dieser Teil der Europäischen Norm legt die Anforderungen zur Vereinheitlichung von Parametern der Qualität der Gleisgeometrie fest, wie sie von verschiedenen Messeinrichtungen gemessen werden. Diese Messeinrichtungen werden in den Teilen 2, 3 und 4 dieser Norm beschrieben. Diese Europäische Norm gilt für alle Parameter der Gleisgeometrie einschließlich Spurweite, Längshöhe, Richtung, Überhöhung (Querhöhe/gegenseitige Höhenlage) und Verwindung. Sie definiert jeden Parameter und legt die Anforderungen an die Messung, die Auswerteverfahren und die Präsentation der Ergebnisse fest.
Applications ferroviaires/Voie - Qualité géométrique de la voie - Partie 1: Caractérisation de la géométrie de voie
Cette EN spécifie les exigences pour l'homologation des parametres de qualité géométrique de la voie tels qu'ils sont mesurés par un véhicule d'enregistrement ou par un systeme manuel. Cette norme s'applique a tout parametre caractérisant la géométrie de la voie, c.-a-d. l'écartement, le nivellement longitudinal, le dressage, le nivellement transversal (dévers), et le gauche. Toutefois, elle ne traite pas en détail des problemes de conicité ou de profil de rail. Enfin, elle définit chaque parametre et spécifie les exigences pour la mesure, les méthodes d'analyse, et la présentation des résultats.

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
