Railway applications - Track - Switches and crossings for Vignole rails - Part 1: Definitions

This European Standard provides an accepted "terminology" for switch and crossing work. With the assistance of diagrams, the various components are given definitions, and these specific names are regarded as obligatory.
The definitions cover the constituent parts and design geometry of switch and crossing work, and include the movement of switches. Additional terminology of a more specific nature will be defined in the relevant part of the series.
The present definitions set out the terms most generally used for the geometrical form and the construction of switches and crossings, omitting those of too special a nature.

European foreword

This document (prEN 13232-1:2020) 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 13232-1:2003.

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.

1 Scope

This document provides an accepted “terminology” for switch and crossing work. With the assistance of

diagrams, the various components are given definitions, and these specific names are regarded as

obligatory.

The definitions cover the constituent parts and design geometry of switch and crossing work.

Additional terminology of a more specific nature will be defined in the relevant part of the series.

The present definitions set out the terms most generally used for the geometrical form and the

construction of switches and crossings, omitting those of too special a nature.

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain

terminological databases for use in standardization at the following addresses:
• ISO Online browsing platform: available at https://www.iso.org/obp
• IEC Electropedia: available at http://www.electropedia.org/
3.1 General definitions
3.1.1

term used to define one party involved in using the EN as the technical basis for a transaction: the

Operator or User of the equipment, or the Purchaser of the equipment on the User's behalf

3.1.2
supplier

term used to define one party involved in using the EN as the technical basis for a transaction: the Body

responsible for the use of the EN in response to the Customer's requirements
3.1.3
contact area

those parts of the rail ensuring the support and/or guidance, inside or outside, of a wheel (see Figure 4)

3.1.4
running table
upper surface of the head of a rail. See Figures 1 and 4

3.1.5
running surface

curved surface defined by the longitudinal displacement of a straight line perpendicular to the centre-

line of the track and tangential to both running tables (see Figure 2)
Figure 2
3.1.6
running plane

flat plane tangential to the running surface at the considered point (see Figure 4)

3.1.7
rail inclination

angle measured as a tangent (e.g. 1 in 20) between the normal to the running surface and the y-y axis of

the rail. See Figure 3. Rail head inclination may be achieved by inclining the rail as shown in figure3 or

by inclining the head profile only, for example by machining

plane parallel to and below the running surface at a dimension “z”. This dimension “z” is 14mm for

interoperable railways with 1435, 1524, 1600 and 1668 mm track gauge or 13 mm for 1520 mm track

gauge. This plane is used for all design work, machining, and measurements (see Figures 4 and 5)

line midway between the running edges on straight track, and half design track gauge inside the

running edge of the larger radius rail in curved track (see Figures 4 and 6)

gauge widening

intended increase in design track gauge. The radius of the low-side rail is decreased, and the distance

3.2.1
switch and crossing work

trackwork ensuring the support and guidance of a vehicle along any given route among various

diverging or intersecting tracks. The term (switch and crossing work) is amplified to include certain

items having other functions (for example, expansion devices)

Note 1 to entry: Switches are in some circumstances described as points - either word is considered acceptable.
