(a) A rail carrier providing transportation subject to the jurisdiction of the Board under this part may not agree or combine with another of those rail carriers to pool or divide traffic or services or any part of their earnings without the approval of the Board under this section or section 11123 of this title . The Board may approve and authorize the agreement or combination if the rail carriers involved assent to the pooling or division and the Board finds that a pooling or division of traffic, services, or earnings— (1) will be in the interest of better service to the public or of economy of operation; and (2) will not unreasonably restrain competition. (b) The Board may impose conditions governing the pooling or division and may approve and authorize payment of a reasonable consideration between the rail carriers. (c) The Board may begin a proceeding under this section on its own initiative or on application.
