Railway applications - Supply voltages of traction systems

This European Standard specifies the main characteristics of the supply voltages of traction systems, *such as traction fixed installations, including auxiliary devices fed by the contact line, and rolling stock, for *use in the following applications : *û railways; *û guided mass transport systems such as tramways, elevated and underground railways mountain *railways, and trolleybus systems; *û material transportation systems. *This European Standard does not apply to *û mine traction systems in underground mines, *û 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, *û suspended cable cars, *û funicular railways. *This European Standard deals with long term overvoltages as shown in the Annex A.
