Division Essential requirement 2.4.1 Section 2:

‘The electrical equipment must not impair the safety and functioning of the control and command and signalling installations.’

This requirement is met by the criteria defined in the control command TSI, in the paragraph dealing with the electromagnetic compatibility of the rolling stock and the signalling system.

The constraints to operation over existing infrastructure are dealt with on a case-by-case basis. It is imperative to respect the limits defined for existing installations. To find out the different infrastructure characteristics, refer to the ‘Register of infrastructure’ in which the information is given on a line by line basis.

The relevant characteristics to validate in respect of this TSI are defined in Section 4.1.9.
