The Commission may authorize any rail carrier willing to do so voluntarily to use the tracks and facilities of a carrier which, on January 14, 1983, was the subject of a proceeding pending under section 77 of the Bankruptcy Act or under subchapter
IV of chapter
11 of title
11. The use of such tracks and facilities shall be under such terms of compensation as the carriers establish between themselves, or if the carriers are unable to agree, under such terms of compensation as the Commission finds to be reasonable. The Commission shall have authority to authorize continued rail service under this section over the lines of any such carrier which has been ordered by the court having jurisdiction over such a carrier to liquidate its properties until the disposition of the properties of the estate of such carrier.
