SIST EN 13232-3:2004/kFprA1:2011

Railway applications - Track - Switches and crossings - Part 3: Requirements for wheel/rail interaction

This part of this European Standard specifies:
- characterisation of wheel and track dimensions;
- geometric design principles for wheel guidance;
- design principles for wheel load transfer;
- deciding whether movable crossings are needed.
These are illustrated by their application to turnout components:
- switches;
- crossings;
- check rails.
but the principles apply equally to more complex layouts.

Overview

EN 13232-3:2003/FprA1 is a CEN European standard that defines requirements for wheel/rail interaction in railway switches and crossings (turnouts). It covers the characterization of wheel and track dimensions, geometric design principles for wheel guidance, principles for wheel load transfer, and guidance on when movable crossings are needed. The standard applies to turnout components such as switches, crossings, and check rails and supports interoperability requirements under EU Directive 2008/57/EC (see Annex ZA).

Keywords: EN 13232-3:2003, wheel/rail interaction, switches and crossings, turnout design, CEN, railway track.

Key Topics and Requirements

• Wheel and track dimension characterisation
  • Definitions and parameters for wheel profiles and rail/head geometry relevant to turnout performance.
• Geometric design for wheel guidance
  • Principles ensuring wheels are guided safely through switches and crossings to minimise derailment risk and wear.
• Wheel load transfer design
  • Concepts for distributing vertical and lateral loads between wheel and rail at key turnout locations.
• Criteria for movable crossings
  • Guidance to decide when a movable nose or swing crossing is required to maintain acceptable wheel/rail contact and reduce impact forces.
• Turnout component application
  • Application of principles to switches, crossings and check rails; principles extendable to more complex layouts.
• Interoperability and regulatory linkage
  • Amendment A1 and Annex ZA clarify the standard’s relationship to the TSI and EU Directive 2008/57/EC, providing a presumption of conformity where cited.

(Note: the standard provides requirements and design principles rather than prescriptive numeric values in this summary.)

Practical Applications

EN 13232-3 is used to:

• Design new turnouts and complex track layouts with predictable wheel/rail behaviour.
• Specify requirements for component manufacturers (switch blades, crossing noses, check rails).
• Assess and upgrade existing switches and crossings to reduce wear, noise and risk of derailment.
• Support conformity assessment and interoperability documentation under EU rail directives.

Keywords: turnout design, movable crossings, rail wear, interoperability, TSI compliance.

Who Should Use This Standard

• Track and turnout designers and engineers
• Infrastructure managers and asset owners
• Manufacturers of switches, crossings and check rails
• Maintenance planners and railway safety assessors
• Regulatory bodies assessing conformity with the EU TSI and Directive 2008/57/EC

Related Standards

• Other parts of EN 13232 (switches & crossings series) and relevant TSI documents for HS/CR infrastructure (see Annex ZA for mappings). For regulatory compliance, consult the corresponding TSI and national implementations.

Keywords: EN 13232 series, railway interoperability, EU Directive 2008/57/EC.

This draft amendment is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical Committee
CEN/TC 256.
This draft amendment A1, if approved, will modify the European Standard EN 13232-3:2003. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has
the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
