The Commission considered that the Council's amendments to the proposal for a directive substantially altered the Commission's objective in its original proposal insofar as they tended to reduce the scope of interoperability and technical compatibility of structural subsystems and, for financial reasons (cost/benefit justification), attached restrictive conditions to the application of TSIs which gave priority to the maintenance of existing national networks. The Commission, for its part, had geared its proposal towards an integrated trans-European high-speed rail system which took account of users' needs and regretted that the Council was unable to support it.�
