Overview
EN 13232-8:2023 - Railway applications - Track - Switches and crossings for Vignole rails - Part 8: Expansion devices (CEN) defines requirements and good practice for devices that permit longitudinal relative rail movement while maintaining correct guidance and support. The standard updates and supersedes earlier editions and is part of the EN 13232 series covering switches and crossings for Vignole (flat‑bottom) rails.
What the standard covers
- Establishes a working terminology for expansion devices, constituent parts and device types (e.g., adjustment switches / bayonet type, expansion switches with movable stock or switch rails).
- Specifies minimum manufacturing requirements for expansion devices and their components.
- Provides codes of practice for inspection and tolerances, including tools, critical dimensions and inspection procedures.
- Defines identification and traceability methods and acceptance testing.
- Describes design inputs and outputs, design rules, performance requirements, materials and assembly documentation.
- Sets procedures for testing longitudinal forces caused by rail expansion/contraction and methods for examining structural defects.
Key technical topics and requirements
- Types and terminology: clear definitions for adjustment switches and expansion switches, expansion capacity, mean/design position and relative displacement.
- Design rules: inputs required from the customer (axle load, tonnage, speed, etc.), wheel/rail interaction considerations, and specific design constraints for expansion behavior.
- Tolerances & inspection: critical dimensions, required inspection instruments and certification practices for manufacture and installation.
- Testing & acceptance: methods for measuring longitudinal forces, acceptance tests and limits/extent of supply.
- Identification: marking and traceability to support maintenance and safety compliance.
Practical applications
- Enables reliable installation of expansion devices in locations where longitudinal rail movement is expected, such as:
- Interrupted continuously welded rail (CWR) joints
- Track sections adjacent to moving civil structures (bridges, viaducts, abutments)
- Layouts where thermal expansion or shrinkage must be accommodated
- Used in new track construction, turnouts (switches and crossings), refurbishment and maintenance projects to ensure safe wheel/rail interaction and long‑term performance.
Who should use this standard
- Railway infrastructure designers and engineers
- Switch & crossing manufacturers and suppliers
- Track installation and maintenance contractors
- Inspection and certification bodies
- Infrastructure asset owners and safety assessors

4 Design
4.1 Design inputs
The following information shall be supplied by the customer to the supplier:
— axle load;
— gross annual tonnage;
— train speed;
— nominal track gauge;
— direction of traffic;
— track geometry.
In addition the customer shall decide:
— the type of expansion device to be applied;
— the expansion capacity of the expansion device as well as the maximum displacement rail/support.
If the latter is not provided, it shall be estimated to be half the expansion capacity of the device;
— the basic rail section and grade;
— the rail inclination to be applied through the expansion device;
— the fastening system to be applied;
— the nominal support spacing;
— type of support structure, e.g. bearer, slab track;
— special requirements, e.g. limits of vertical and horizontal end rotations, limits of local vertical and
horizontal radii of track, limits of uplift movements on rail supports adjacent to the gap between
the structure and the abutment or between the structures.
The following elements shall be agreed between customer and supplier:
— the special rail profiles to be applied for the construction (if applicable);
— the constructional length;
— the machining details of the rail sections;
— the maximum support spacing in service.
4.2 Design rules
4.2.1 General rules
4.2.1.1 Support panel
In the case where one side is moveable, a number of bearers shall be restrained from moving when laid
on ballast. This is normally a minimum of four bearers. The incoming rails may, for example, have low
resistance fastenings on the restrained bearers to permit movement of the moveable rails.
All restrained bearers shall be linked to each other. This can be achieved by the use of a bearer strap,
guard rail, continuous base plate etc.
In the case when both sides are moveable, the bearers shall be restrained from moving by means of a
steel strap. This is to ensure bearer distance does not change and prohibits the bearers from moving
from their nominal position during operation and/or maintenance.
4.2.1.2 Fastenings
The fastenings are dependent on the application of the expansion device; therefore the rail fastenings
shall be specified by the cust

The standard EN 13232-8:2023 presents a comprehensive framework for railway applications specifically focusing on switches and crossings for Vignole rails, with a particular emphasis on expansion devices. Its scope plays a crucial role in the development and maintenance of robust railway infrastructure by addressing essential aspects of expansion devices. One of the strengths of EN 13232-8:2023 is its establishment of a clear and concise working terminology for expansion devices and their constituent parts. This foundational element aids in enhancing communication among stakeholders, ensuring that all parties involved have a mutual understanding of the components and their functions. In terms of manufacturing, the standard specifies minimum manufacturing requirements for expansion devices and their parts. This aspect is vital as it ensures a uniform quality and performance standard across the industry, ultimately contributing to the safety and reliability of railway operations. By defining these requirements, the standard reduces variability in manufacturing practices, leading to more consistent outcomes. The formulation of codes of practice for inspection and tolerances is another key strength. This section of the standard provides guidance for the evaluation of expansion devices, thereby facilitating effective quality control processes. The specified tolerances ensure that the components will function properly within their designated environments, which is essential for minimizing risks in railway applications. Moreover, EN 13232-8:2023 defines the method by which expansion devices and their parts should be identified and traced. This provision enhances traceability, thereby improving accountability throughout the supply chain. In the event of a failure or issue, the ability to trace back components to their origin plays a pivotal role in mitigating risks and ensuring accountability. Overall, EN 13232-8:2023 serves as a relevant and authoritative standard for railway applications, focusing on the vital area of expansion devices. By establishing clear terminology, manufacturing requirements, inspection codes, and traceability methods, the standard significantly contributes to the advancement and safety of railway infrastructure.
