What Is UIC Leaflet 814?

UIC Leaflet 814 is a standard from the International Union of Railways (UIC) that specifies the design, testing, and operational requirements for braking systems on railway vehicles.
It ensures safe, reliable, and interoperable braking performance for both freight and passenger rolling stock.

Importance of UIC Leaflet 814

Braking systems are critical for train safety, operational reliability, and ride comfort.
UIC 814 standardizes brake performance, system integration, and emergency response to maintain consistent safety levels across European railways.

Specifies functional and emergency braking requirements
Defines test procedures for system reliability
Supports interoperability between different wagon types
Ensures safe train operation under normal and degraded conditions

Scope and Technical Coverage

The leaflet applies to all types of rolling stock including freight wagons, passenger coaches, and locomotives.
It provides guidance on brake system design, installation, testing, and maintenance.

Brake types and system configurations
Performance requirements under load and speed conditions
Emergency braking and fail-safe mechanisms
Integration with vehicle control and safety systems
Maintenance, inspection, and testing procedures

Key Technical Parameters
