Approximately 210 km of railway lines in the German Eifel region are set to be electrified. To ensure rapid implementation, an innovative railway power supply system operating at 2AC 2×25 kV 16.7 Hz will be deployed, running in parallel with the overhead line system.
Enotrac has been supporting Deutsche Bahn in the overall risk management process since the concept phase. As part of the joint CSM process involving DB Energie and DB InfraGO, Enotrac is contributing to the safe and efficient realisation of the electrification project. This support will continue throughout the implementation phase.

About the project
In 2021, several railway lines in the Eifel region were severely damaged or destroyed by flooding. As part of the reconstruction efforts, the Eifel line is set to be electrified with a new type of railway power supply system. To enable railway power transmission, 2AC 2×25 kV 16.7 Hz connection lines will be installed, running parallel to the overhead contact line (1AC 15 kV 16.7 Hz). The existing higher-level traction power network (2AC 110 kV 16.7 Hz) will feed into these new connection lines (2AC 2×25 kV 16.7 Hz) through two network coupling transformers. Along the route, three substations will connect the overhead line network (1AC 15 kV 16.7 Hz) to the new connecting lines, while switching stations will be located at junctions to other overhead lines.
The electrification project includes the Eifelbahn from Hürth to Trier-Ehrang, the Voreifelbahn from Bonn to Euskirchen, and the Erfttalbahn from Euskirchen to Bad Münstereifel. The new railway energy transmission system will be exclusively used on the Eifelbahn, whereas the Voreifelbahn and Erfttalbahn will operate with the standard 1AC 1×15 kV 16.7 Hz supply system.
Our contribution
As part of this project, Enotrac assumed several critical tasks to ensure a safe and compliant implementation.
The process began with a thorough review of the basics, guided by relevant laws, regulations, and codes of practice. Building on this foundation, the Enotrac team conducted a significance analysis and developed a comprehensive system description. A key focus was identifying and categorising potential hazards, followed by defining targeted measures to mitigate the identified risks. In line with the EN 50562 standard, Enotrac’s experts compiled and meticulously verified the required evidence. The entire Common Safety Method (CSM) process was documented in a detailed report, ensuring full traceability. Close collaboration with the assessment body (AsBo) ensured that all requirements were met, and the project fully adhered to the established safety standards.
