This European Standard is intended to be used to set up the requirements for the acceptance of rolling stock on infrastructure in the field of
- Co-ordination of protection principles between power supply and traction units, especially fault discrimination for short circuits;
- Co-ordination of installed power on the line and power demand of the trains;
- Co-ordination of traction unit regenerative braking and power supply receptivity;
- Co-ordination of harmonic behaviour.
This standard deals with the definition and quality requirements of the power supply at the interface between traction unit and fixed installations. The standard specifies the interface between rolling stock and electrical fixed installations for traction, in the frame "supply system". The interaction between pantograph and overhead line is dealt in EN 50367. The interaction with subsystem "control-command" (especially signalling) is not dealt with in the standard.
Requirements are given for the following categories of line:
- TSI lines (high speed and conventional),
- classical lines.
For classical lines, values, if any, are given for the existing European networks. A set of values is also specified for the future network, which is named "target" network.
The following electric traction systems are concerned:
- railways;
- guided mass transport systems that are integrated with the railways;
- material transport systems, that are integrated with the railways.
This standard does not apply retrospectively to rolling stock already accepted by infrastructure managers. However, on new infrastructure, existing rolling stock may be accepted by the infrastructure manager, provided there is an agreement.
Information is given to the train operating companies on electrification parameters to enable them to confirm after consultation with the rolling stock manufacturers that there will be no consequential disturbance on the electrification system.
