Stacionarieji geležinkelio įrenginiai. Elektrinės traukos maitinimo sistemų sauga. 2 dalis. Bendrieji principai, taikomi ne įprastiniam naudojimui, funkcijoms ir savybėms

This document defines the process, protective measures and demonstration of safety in accordance with prEN 50126-1:2017 and prEN 50126-2:2017 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: This document supports the implementation of non-conventional applications, functions and properties in electric traction power supply systems that remain after the application of prEN 50562 1:2025. NOTE EN 50562 1 establishes the code of practice for conventional applications, functions and properties in electric traction power supply systems. This document applies to electric traction power supply systems, which are new or are undergoing major changes as defined in the legal framework. For similar technology and similar hazardous scenarios, the safety considerations can be used as a guideline. This document does not apply to: — 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 other malevolent acts etc. It is assumed that those aspects are handled on the overall system level. NOTE For railways IT-security is covered in CLC/TS 50701. Because of the short life cycles of IT-security applications it is advisable to separate IT-security functions from safety functions at least on virtual levels. E.g. the frequent patch processes for updating the IT-security applications is expected to be independent from Safety applications.
