This European Standard covers overhead contact lines for electric traction in heavy and light railways as well as trolley buses and industrial railways owned by public and private operators. This standard is applicable to both new overhead contact system installations and the reconstruction of existing overhead line systems such as EN 50119:2020 Railway applications - Fixed installations - Electric traction overhead contact lines for example.

This standard includes the requirements and testing for the design and construction of overhead contact lines, the requirements for structures and their structural calculations as well as verifications and requirements for designing individual parts and assemblies.
