CCM procedure exists at ERA. This procedure is based on the former procedure originally approved by the ERTMS Control Group and takes account of the return of experience accumulated over the past years.

Any modification to the ERTMS specification is analysed via a Change Request (CR). CRs can only be submitted in the CCM tool by the representative bodies. More information about the submission of CRs can be found in the restricted ERTMS area.
