If, except for the pendency of the case under this chapter, transfer of, or operation of or over, any of the debtor’s rail lines by an entity other than the debtor or a successor to the debtor under the plan would require approval by the Board under a law of the United States, then a plan may not propose such a transfer or such operation unless the proponent of the plan initiates an appropriate application for such a transfer or such operation with the Board and, within such time as the court may fix, not exceeding 180 days, the Board, with or without a hearing, as the Board may determine, and with or without modification or condition, approves such application, or does not act on such application. Any action or order of the Board approving, modifying, conditioning, or disapproving such application is subject to review by the court only under sections 706(2)(A), 706(2)(B), 706(2)(C), and 706(2)(D) of title 5.
