(9)In its report to the European Parliament and to the Council on its experience acquired in applying Regulation (EC) No 91/2003, the Commission referred to the fact that long-term developments will probably result in the suppression or the simplification of the data already collected under that Regulation, and that the aim is to reduce the data transmission period for annual data on rail passengers. The Commission should continue to provide reports at regular intervals on the implementation of this Regulation.
