This also includes requirements applicable to vehicles on electrified lines.
It also applies to all aspects of fixed installations which are necessary to ensure electrical safety during maintenance work within electric traction power supply systems.
This document applies to new electric traction power supply systems and major revisions to electric traction power supply systems for:
a) railways;
b) guided mass transport systems such as
1) tramways,
2) elevated and underground railways,
3) mountain railways,
4) trolleybus systems,
5) electric traction power supply systems for road vehicles, which use an overhead contact line system, and
6) magnetically levitated systems, which use a contact line system;
c) material transportation systems.
This document does not apply to:
a) electric traction power supply systems in underground mines,
b) 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 electric traction power supply system,
