EN 15220: Railway applications — Brake indicators standard

Railway systems rely on effective braking mechanisms to ensure safe and efficient operations. As an engineer or technical personnel in the railway industry, understanding and adhering to relevant standards is crucial. One such important standard is EN 15220: Railway applications — Brake indicators.

1. Introduction:

EN 15220 is a European standard that specifically addresses brake indicators used in railway applications. It provides guidelines and requirements for the design, construction, and performance of brake indicators installed on rolling stock. These indicators play a vital role in providing essential information about the status of brakes to train operators, maintenance personnel, and passengers.

2. Scope and Purpose:

The primary purpose of EN 15220 is to establish uniform criteria for the functionality, reliability, and visibility of brake indicators across different types of rolling stock. The standard ensures that brake indicators meet specific technical specifications, enabling accurate monitoring of the braking system’s condition.

3. Technical Requirements:

EN 15220 outlines various technical requirements that brake indicators must fulfill. This includes specifications related to the display format, color coding, brightness, contrast, readability, and response time. The standard also covers aspects such as mounting arrangements, electrical connections, and compatibility with existing signaling systems.

4. Performance Evaluation:

Brake indicators undergo thorough testing to assess their compliance with the standard’s requirements. These tests evaluate parameters such as luminous intensity, resistance to mechanical shock and vibration, temperature resistance, and electromagnetic compatibility. By meeting these criteria, brake indicators can ensure reliable and consistent performance under varying operating conditions.

5. Usage and Benefits:

Complying with EN 15220 offers several benefits to railway operators and passengers. Brake indicators provide clear visual feedback on the condition of the braking system, allowing train operators to make informed decisions. Maintenance personnel can quickly identify issues and perform necessary repairs or replacements promptly, ensuring optimal safety and reducing potential downtime. Moreover, passengers can have confidence in the functionality of the braking system, enhancing their overall experience and trust in railway services.

In conclusion, EN 15220 plays a crucial role in standardizing the design and performance of brake indicators in railway applications. Adhering to this standard ensures that brake indicators meet specific technical requirements, enabling accurate monitoring of the braking system’s condition. By providing clear and reliable information, these indicators contribute to safer and more efficient railway operations.
