Division 7.1 PrinciplesF1

Implementation of this TSI and conformity with the relevant points of this TSI must be determined in accordance with an implementation plan that must be drawn up by each Member State for the lines for which they are responsible.

This plan must take into account:

1. (a)

   the specific human factors issues associated with operating any given line;

2. (b)

   the individual operating and safety elements of each line involved; and

3. (c)

   whether implementation of the element(s) under consideration is to be:

   • for all trains on the line, or not,

   • only for certain lines,

   • applicable on all lines,

   • applicable to all trains running on the network;

4. (d)

   the relationship with implementation of the other subsystems (control-command and signalling, rolling stock, etc.).

At this time any specific exceptions that may be applicable should be taken into account and documented as part of the plan.

The implementation plan must take into account the various levels of potential for implementation from any of the following events, namely when:

1. (a)

   a railway undertaking or infrastructure manager commences operations;

2. (b)

   a renewal or upgrade to the existing operational systems of a railway undertaking or infrastructure manager is introduced;

3. (c)

   new or upgraded infrastructure, energy, rolling stock or command control and signalling subsystems, requiring a corresponding set of operating procedures, are put into service.

It is commonly understood that the full implementation of all elements of this TSI cannot be complete until the hardware (infrastructure, control and command, etc.) that is to be operated has been harmonised. The guidelines set out in this Chapter must therefore only be seen as an interim phase supporting migration to the target system.
