In that case the Commission shall, on a proposal from the Committee of  Experts, make such recommendations, as it considers necessary to avoid any serious  disturbances in the transport sector.

The rates and conditions referred to in the fourth paragraph of Article 70 which are in force  when the Commission is set up shall be notified to the Commission, which shall allow such  time for their modification as may be necessary to avoid any serious economic disturbance.

The governments concerned shall, after consulting the Committee of Experts, authorize the  Luxembourg Government, in so far as the special position of Luxembourg Railways makes it  necessary, to continue after the transitional period to operate the arrangements adopted.
