This 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 50562-2 supports the implementation of non-conventional applications in electric traction power supply systems.
NOTE EN 50562 Part 1 establishes the code of practice for 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 other malevolent acts etc. 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 patch processes for updating the IT-Security applications should be independent
from Safety applications.
