EN 15734-1:2010/prA1

Overview

EN 15734-1:2010/prA1 is a crucial European standard that specifies the requirements and definitions for braking systems of high-speed trains. Managed by CEN Technical Committee CEN/TC 256, this standard aligns with the latest EU legislation, specifically Directive (EU) 2016/797, which governs interoperability within the rail system. As an amendment to EN 15734-1:2010, it updates annex ZA to ensure compliance with current EU directives. This standard plays a key role in defining safety, performance, and compatibility criteria for braking systems critical to the operation of high-speed rail networks.

Key Topics

• Braking System Requirements: Defines essential safety and performance criteria for service brakes, emergency brakes, parking brakes, and dynamic braking systems tailored for high-speed trains.
• Safety Definitions: Clarifies terminology used consistently across railway applications to ensure precise communication regarding braking components and operations.
• Interoperability Compliance: Aligns with the essential requirements of Directive (EU) 2016/797, ensuring braking systems support the interoperability of rolling stock across EU rail networks.
• Brake State and Fault Indication: Specifies monitoring, fault detection, and diagnostic functions essential for maintaining braking system reliability and safety.
• Wheel-Rail Adhesion and Protection: Covers protection mechanisms such as wheel slide protection to enhance braking efficiency under varying rail conditions.
• Compatibility and Control Commands: Addresses the integration of braking systems with traction control and other on-board systems, supporting coordinated and reliable train operation.
• Emergency and Rescue Braking Requirements: Establishes performance standards ensuring braking systems are effective in critical situations and suitable for rescue operations.

Applications

EN 15734-1:2010/prA1 serves a vital role for a range of stakeholders in the railway industry, including:

• Train Manufacturers: To design and manufacture braking systems for high-speed trains that comply with up-to-date EU regulations and interoperability standards.
• Rail Operators: Ensures braking systems meet safety and operational performance criteria, reducing risk and improving passenger safety.
• Regulatory Bodies and Certification Authorities: Provides a reference framework for assessment, certification, and authorization of rail vehicles within the EU rail infrastructure.
• Component Suppliers: Guides the development of braking system components compatible with high-speed train requirements and interoperable with various rolling stock.
• Rail Infrastructure Managers: Supports integration of trains within the railway network by specifying standardized braking requirements that affect operation and safety.

Related Standards

• Directive (EU) 2016/797: EU legislative framework addressing interoperability and safety of the rail system, which EN 15734-1:2010/prA1 supports through compliance requirements.
• TSI for Rolling Stock – Locomotives and Passenger Rolling Stock (Commission Regulation EU No 1302/2014): Technical Specifications for Interoperability referencing this standard as a means to demonstrate conformity.
• EN 15734-2: Braking systems of high-speed trains – Part 2: Complements Part 1 by providing detailed technical specifications and testing procedures for braking systems.
