European foreword
This document (prEN 13232-6:2020) 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 13232-6:2005+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 inspection of layouts.---------------------- Page: 5 ----------------------
