Railway applications - Track - Switches and crossings for Vignole rails - Part 2: Requirements for geometric design

This document:
—   establishes the design process for switches and crossings (S&C), and the use of the other parts of this standard;
—   specifies the geometric design principles for wheel guidance;
—   establishes the basic limits of supply;
—   establishes the applied forces and their adequate support;
—   specifies tolerance levels.
These are illustrated herein by application to a turnout. The main switch and crossing components are represented in turnouts and the principles used in turnouts apply equally to more complex layouts.

—   spécifie les niveaux des tolérances.
Dans le présent document, ces aspects sont présentés en les appliquant aux branchements. Les principaux composants des appareils de voie sont représentés dans des branchements. Les principes appliqués dans les branchements sont également applicables dans les assemblages plus complexes.

Železniške naprave - Zgornji ustroj proge - Kretnice in križišča za Vignolove tirnice - 2. del: Geometrijske zahteve pri projektiranju

Ta del evropskega standarda zajema naslednje vsebine:
– načela geometrijskega projektiranja za usmerjanje koles;
– opredelitev osnovnih omejitev dobave;
– delovanje sil in njihova ustrezna podpora;
– ravni tolerance.
Te vsebine so v tem dokumentu ponazorjene z uporabo za kretniški sistem. Glavni sestavni deli kretnic in križišč so predstavljeni v kretniških sistemih, pri čemer se načela v zvezi s kretniškimi sistemi prav tako uporabljajo za kompleksnejše postavitve.

European foreword
This document (EN 13232-2:2023) has been prepared by Technical Committee CEN/TC 256
“Railway applications”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of
an identical text or by endorsement, at the latest by April 2024, and conflicting national
standards shall be withdrawn at the latest by April 2024.
Attention is drawn to the possibility that some of the elements of this document may be the

This document supersedes EN 13232-2:2003+A1:2011.
This series of standards “Railway applications – Track – Switches and crossings for Vignole
rails” covers the design and quality of switches and crossings in flat bottomed rail. The list of
Parts is as follows:
— Part 1: Definitions
— Part 2: Requirements for geometric design
— Part 3: Requirements for wheel/rail interaction
— Part 4: Actuation, locking and detection
— Part 5: Switches
— Part 6: Fixed common and obtuse crossings
— Part 7: Crossings with moveable parts
— Part 8: Expansion devices
— Part 9: Layouts
Part 1 contains terminology used throughout all parts of this series. Parts 2 to 4 contain basic
design guides and are applicable to all switch and crossing assemblies. Parts 5 to 8 deal with
particular types of equipment including their tolerances. These use Parts 1 to 4 as a basis. Part 9
defines the geometric and non-geometric acceptance criteria for inspection of layouts.
The changes introduced in this document set the geometric parameters for switch and crossing
design in the context of the design process, providing more detail to the user of the standard. A
number of figures have been also updated to improve clarity.
This document has been prepared under a Standardization Request given to CEN by the
European Commission and the European Free Trade Association.
Any feedback and questions on this document should be directed to the users’ national
standards body. A complete listin
