Foreword
This document (prEN 13232-2:2014) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede 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 functional and geometric
dimensions and tolerances for layout assembly.
The following terms are used within to define the parties involved in using the EN as the technical basis for a
transaction:
Customer the Operator or User of the equipment, or the Purchaser of the equipment on the User's behalf.
Supplier the Body responsible for the use of the EN in response to the Customer's requirements.
prEN 13232-2:2014 (E)
1 Scope
This part of this European Standard covers the following subjects:
 describe the design process of switches and crossings, and the use of the other parts of this standard;
 geometric design principles for wheel guidance;
 definition of basic limits of supply;
 applied forces and their adequate support;
 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.
