What is BS EN 50119 about?
BS EN 50119 applies to overhead contact line systems in heavy railways, light railways, trolleybuses, and industrial railways of public and private operators.
BS EN 50119 applies to new installations of overhead contact line systems and for the complete renewal of existing overhead contact line systems.
BS EN 50119 contains the requirements and tests for the design of overhead contact lines, requirements for structures and their structural calculations and verifications as well as the requirements and tests for the design of assemblies and individual parts.
NOTE: BS EN 50119 does not provide requirements for ground-level conductor rail systems.
Who is BS EN 50119 for?
BS EN 50119 on electric traction overhead contact lines is useful for:
- Railway engineers
- Electrical and mechanical engineers
- Manufacturers of railway electric traction equipment
Why should you use BS EN 50119?
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses, or trams. BS EN 50119 provides general requirements and characteristics of the overhead contact line system designs for the supply of electrical power.
BS EN 50119 provides information on vehicle types and the characteristics of the current collectors that are to be used on the overhead contact line system design.
BS EN 50119 provides the test methods to determine the mechanical and electrical properties of contact lines.
Overall, BS EN 50119 helps you with the structures and foundations for overhead contact line systems with regard to the safety of the public, durability, robustness, maintainability, and environmental considerations.
What’s changed since the last update?
BS EN 50119:2020 supersedes BS EN 50119:2009+A1:2013. BS EN 50119:2020 includes some technical changes with respect to BS EN 50119:2009+A1:2013. These include:
- Requirements for urban mass transportation systems are included
- Requirement for rigid overhead contact line (ROCL) are included
- Clearances and geometry of overhead contact line are improved
- Urban aspects are added, e.g. wall anchors
- Monitoring devices and automatic earthing and short-circuiting equipment are included.
