Railway applications - Braking - Empty-loaded changeover devices
This European Standard is applicable to empty-loaded changeover devices designed to automatically sense when the load of a railway vehicle reaches a defined value (changeover mass), which represents the point at which the vehicle is classed as "loaded" and thereby requires the brake force to be adjusted accordingly to achieve the required brake performance. This European Standard also covers manually operated emptyloaded changeover devices and the associated changeover plates.
This European Standard specifies the requirements for the design, dimensions, manufacture and testing of empty-loaded changeover devices.

General Information

Overview
EN 15624:2008/FprA1 is a European Standard developed by CEN that addresses railway braking systems, specifically focusing on empty-loaded changeover devices. These devices are critical components in railway technology, designed to automatically detect when the load on a railway vehicle reaches a predefined threshold-known as the changeover mass. This detection triggers an adjustment in brake force to ensure optimal braking performance whether the vehicle is loaded or empty.
The standard sets forth comprehensive specifications for the design, manufacturing, dimensions, and testing of both automatic and manually operated empty-loaded changeover devices, including associated changeover plates. Its adoption supports safety, reliability, and interoperability within railway operations across Europe, ensuring compliance with relevant EU directives.
Key Topics
- Automatic Load Sensing: Devices must automatically identify when the vehicle load crosses the changeover mass to switch braking settings.
- Manual Changeover Devices: Guidelines also cover manually operated equipment, ensuring standardized design and operation for varying railway applications.
- Design Requirements: Detailed specifications address mechanical dimensions, materials, and construction standards to guarantee consistent performance.
- Testing Protocols: Rigorous testing procedures are outlined to verify device functionality under different loading conditions and to certify compliance.
- Interoperability Compliance: Aligns with EU Directive 2008/57/EC on rail system interoperability, enabling seamless integration within European rail networks.
- Safety and Reliability: Emphasizes braking performance standards critical to maintaining operational safety for freight and passenger rail vehicles.
Applications
EN 15624:2008/FprA1 applies primarily to railway vehicles that require adaptive braking systems based on load-such as freight wagons and passenger trains. Key applications include:
- Freight Wagons: Adjustment of braking force for wagons carrying variable loads, enhancing both safety and equipment longevity.
- Passenger Coaches: Ensuring appropriate brake force depending on passenger capacity, thus maintaining consistent stopping distances.
- Railway Brake System Manufacturers: Providing a design and testing framework for developing compatible changeover devices.
- Rail Infrastructure Operators: Implementing and maintaining braking systems that comply with European interoperability regulations.
- Safety Certification and Compliance Testing: Facilitates harmonized evaluation processes for equipment approval across multiple countries.
This standard supports the development and deployment of railway braking systems that respond dynamically to operational conditions, helping to optimize safety, performance, and regulatory compliance.
Related Standards
EN 15624:2008/FprA1 closely interacts with other railway standards and EU directives related to rail system interoperability and braking technology, including:
- EU Directive 2008/57/EC – Governs interoperability of the European rail system, under which this standard confers a presumption of conformity when implemented.
- EN 45545 – Railway applications focusing on fire protection, often considered alongside braking standards for comprehensive safety design.
- EN 14531 – Braking system components standards which complement changeover device specifications.
- TSI (Technical Specifications for Interoperability) RST Freight Wagons – Provides broader specifications for freight wagon design and safety including braking performance.
- CEN/TC 256 Standards – A series of standards related to railway applications that support harmonization and technical advancement in railway engineering.
Compliance with EN 15624:2008/FprA1 ensures that braking systems incorporate state-of-the-art load-sensitive changeover technology, enabling safer and more efficient railway operations across Europe’s diverse rail network.
For manufacturers, engineers, and railway operators, adherence to EN 15624:2008/FprA1 promotes improved braking responsiveness, reliable load detection, and regulatory compliance-all crucial factors in achieving safe and interoperable railway transportation.
