EN 13803: Standards for Railway Light Signals and Signal Lamps

Introduction to EN 13803

EN 13803 is a European standard specifying electrical and optical requirements for railway light signals. It ensures that signal lamps are reliable, visible, and interoperable across different railway networks, contributing to safe train operations.

Scope and Purpose

The standard applies to the design, installation, and testing of light signals used in railway signaling systems. Its purpose is to maintain visibility under various weather conditions, standardize electrical and optical performance, and support interoperability between signaling equipment.

Key Components

• Optical Performance: Requirements for luminous intensity, color, and viewing angle to ensure clear visibility.
• Electrical Requirements: Specifies voltage, current, and power consumption limits for signal lamps.
• Reliability and Maintenance: Defines service life, failure rate, and maintenance intervals for signaling equipment.
• Compatibility: Ensures integration with interlocking systems, ETCS, and other signaling equipment.
