Such fitting should in principle be carried out in the frame of the EU funded project. In certain cases, it is however necessary to grant a derogation to this imple- mentation rule. The scope of such derogation is limited to the implementation strategy of the ‘control-command and signalling TST. () ERA/REC/2011-03/ERTMS.
