UIC Leaflet 606-2: Standardizing Rail Signaling and Trackside Cabling

Introduction to UIC Leaflet 606-2

UIC Leaflet No: 606-2 is an international standard from the International Union of Railways (UIC) that defines specifications for cabling and telecommunication systems in railway signaling. It ensures the safe, reliable, and interoperable operation of trackside and onboard equipment.

Scope and Purpose

The leaflet provides guidance for the design, installation, testing, and maintenance of railway signaling cabling, including fiber optic and copper systems. Its main goal is to standardize communication infrastructure to minimize faults, enhance safety, and support high-speed and conventional rail operations.

Key Components

• Cabling Standards: Defines specifications for copper and fiber optic cables, connectors, and routing.
• Trackside Equipment: Establishes requirements for signal cabinets, junction boxes, and protective enclosures.
• Testing and Maintenance: Standardizes procedures for cable testing, fault detection, and preventive maintenance.
• Interoperability: Ensures compatibility between different rail signaling systems and control centers.
