Description of 25/30467840 DC 2025This document defines the process, protective measures and demonstration of safety in accordance with EN 50126-1 and-2:2017 for AC and DC electric traction power supply systems for railways. This document can also be applied to urban rail and trolleybus systems. All these systems can be elevated, at-grade and underground. This document has two parts: EN 50562 Part 1 establishes the code of practice for conventional applications in electric traction power supply systems. NOTE EN 50562 Part 2 supports the implementation of non-conventional applications in electric traction power supply systems. This document applies to electric traction power supply systems, which are new or are undergoing major changes. For similar technology and similar hazardous scenarios, the safety considerations can be used as a guideline. This document does not apply to other systems including those listed below as they were not considered: – underground mine traction systems, – cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the traction power supply system, – suspended cable cars, – funicular railways, – magnetic levitated systems, This document does not consider aspects like IT-security or protection against any other malevolent acts. It is assumed that those aspects are handled on the overall system level. NOTE For railways IT-security will be covered in TS 50701 Railway Applications – IT-Security. Because of the short life cycles of IT Security applications, it is recommended to separate IT-Security functions from Safety functions at least on virtual levels. E.g. the frequent
