European foreword

This document (prEN 13232-5:2020) 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 13232-5:2005+A1:2011.

This document has been prepared under a mandate given to CEN/CENELEC/ETSI by the European

Commission and the European Free Trade Association, and supports essential requirements of EU

Directive 2016/797/EU.

For relationship with EU Directive 2016/797/EU, see informative Annex ZA, which is an integral part of

this document.

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 the inspection of layouts.

augmented switch

switch with inside headcut shifted towards the stock rail thereby increasing the width of the switch rail

profile

Note 1 to entry: The amount of augment may be parallel to the stock rail running edge or tapered.

4 Performance requirements
4.1 General

Switch operating, signalling systems, heating systems, load bearing supports, maintainability, safety and

security against theft are all major factors which shall be taken into account during the design of

switches.

The performance criteria of switches shall be based on information given by the customer. The design

and selection of type of switches will be influenced by axle loads, frequency of traffic and speed.

Information supplied in Clauses 5 and 6 shall be used in the selection of the type of switches and the

design.
4.2 Materials

The materials used shall be specified using the respective European Standard or by their mechanical

and chemical characteristics where a European Standard does not exist.

The grade and specification of the rails to be used shall be specified by the customer according to series

EN 13674. Materials for other components shall be agreed between customer and supplier.
