Fixed installations for railway applications - Electrical safety, earthing and the return circuit - Part 2: Provisions against the effects of stray currents caused by DC traction systems; German version EN 50122-2:2022+A1:2025
Abstract
This document specifies requirements for protective provisions against the effects of stray currents, which result from the operation of DC traction systems. As several decades experience has not shown evident corrosion effects from AC traction systems and ac-tual investigations are not completed, this document only deals with stray currents flowing from a DC traction system. This document applies to all metallic fixed installations which form part of the traction system, and also to any other metallic components located in any position in the earth, which can carry stray currents resulting from the operation of the railway system. This document applies to all new DC lines and to all major revisions to existing DC lines. The principles can also be applied to existing electrified transportation systems where it is necessary to consider the effects of stray currents. This document does not specify working rules for maintenance but provides design requirements to allow maintenance. The amendment A1 to EN 50122-2 includes changes to the title of the standard and sections 4 to 8, Annexes A to D and the bibliography.
