CEN/TC 256/SC 1/WG 18 - Switches and crossings - Performance and acceptance

This European Standard deals with mechanical rail joints for flat bottom rails 46 kg/m and over. The scope of this standard is: to
establish requirements for insulated and non-insulated rail joints, for stressed rail (continuous welded rail, CWR) and unstressed rail (jointed track); to define mechanical and electrical requirements for type approval and for acceptance of insulated rail joints which are manufactured in a factory (prefab construction) as well as assembled onsite (site construction). This standard specifies the minimum requirements. Special applications as for instance tram systems may require different demands in certain paragraphs and should be agreed between customer and supplier. The scope also excludes expansion joints (it is covered in EN 13232-8), and special joints in switch constructions.

This document determines the interface between moveable parts and the actuation, locking and detection equipment, and defines the basic criteria for switches and crossing with moveable parts in respect of the interface.
It concerns:
—   rules, parameters and tolerances for alternative positions of the moveable parts;
—   criteria and limits for the forces which move and restrain the moveable parts.

This document:
—   Establish a working terminology for fixed crossings and their constituent parts, and identifies the main types;
—   specifies the different and varying ways by which crossings can be described using the following parameters:
—   geometry of the crossing;
—   types of construction;
—   design criteria;
—   manufacturing processes;
—   tolerances and inspection.

This document:
—   establishes a working terminology for crossings with moveable parts, which means crossings with moveable parts to close the gap of the running edge, and their constituent parts, and identify the main types;
—   lists the minimum requirements for the manufacture of crossings with moveable parts and/or their constituent parts;
—   formulates codes of practice for factory inspection and tolerances for crossings with moveable parts and/or their constituent parts;
—   establishes the limits and extent of supply;
—   lists the method by which crossings with moveable parts and their constructional parts should be identified;
—   lists the different and varying ways by which crossings with moveable parts can be described, using the following parameters:
—   geometry of crossings;
—   types of construction;
—   performance requirements;
—   design criteria;
—   tolerances and inspection.

The scope of this part is:
-   to describe the design process of switches and crossings, and the use of the other parts of this standard;
-   to define the main criteria to be taken into account during the design of the layout, including the safety and functional dimensions as well as geometrical and material aspects;
-   to define the main criteria to be verified during the design approval;
-   to define the geometrical and non-geometrical acceptance criteria for inspection of layouts assembled both in the fabrication plant and at track site in case of layouts that are delivered non or partially assembled or in a "kit" form;
-   to determine the limits of supply;
-   to define the minimum requirements for traceability.
This European Standard applies only to layouts that are assembled in the manufacturing plant or that are assembled for the first time at trackside.
Other aspects such as installation and maintenance also influence performance; these are not considered as part of this European Standard.

This document:
—   establishes a working definition for switches and their constituent parts and identify the main types;
—   specifies the minimum requirements for the manufacture of the switches and/or constituent parts;
—   specifies codes of practice for inspection and manufacturing tolerances of both full and half sets of switches and their constituent parts;
—   establishes the limits and scope of supply;
—   lists the methods by which switches and their parts should be identified and traced;
—   lists the different and varying ways by which switches can be described using the following parameters:
—   geometry of the switches;
—   types of construction;
—   performance requirements;
—   design criteria;
—   tolerances and inspection.

This document defines the main wheel/track interaction criteria to be taken into account during the geometrical design of railway switches and crossings (S&C) layouts.
It specifies:
—   characterization of wheel and track dimensions;
—   geometric design principles for wheel guidance;
—   design principles for wheel load transfer;
—   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 units. There are also simplified definitions of the safety and functional dimensions, which can be used in conjunction with the general principles as the basis for more in-depth assessment.

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.

This part of EN 13232 covers the following subjects: to establish a working terminology for expansion devices, for their constituent parts and for the types; to specify the minimum manufacturing requirements for expansion devices and their constituent parts; to formulate codes of practice for inspection and tolerances; to define the method by which expansion devices and their parts should be identified and traced.

This document:
—   establishes the design process for switches and crossings (S&C), and the use of the other parts of this standard;
—   specifies the geometric design principles for wheel guidance;
—   establishes the basic limits of supply;
—   establishes the applied forces and their adequate support;
—   specifies 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.

The scope of this European Standard is:
-   to establish material requirements for cast austenitic manganese steel for fixed crossings and cradles for crossings with moveable parts designed to be welded or bolted to rails;
-   to formulate codes of practice for inspection, testing of un-machined and machined heat-treated castings;
-   to list the methods by which crossings should be identified and traced;
-   to define limits of weld rectification by the supplier;
-   special requirements for pre-hardened crossings.
Geometrical aspects, as machining tolerances and inspection of finished crossings are covered in EN 13232-6 and EN 13232-7 and therefore not in this European Standard.
This European Standard specifies the minimum requirements for cast manganese crossing components. Special applications (for instance tram systems) can require different demands in certain paragraphs and need to be agreed between customer and supplier.
