(b)In a proceeding subject to this Section, the plaintiff, at any time after the complaint has been filed and before judgment is entered in the proceeding, may file a written motion requesting that, immediately or at some specified later date, the plaintiff either: (i) be vested with the fee simple title (or such lesser estate, interest, or easement, as may be required) to the real property, or a specified portion of that property, which is the subject of the proceeding, and be authorized to take possession of and use the property; or (ii) only be authorized to take possession of and to use the property, if possession and use, without the vesting of title, are sufficient to permit the plaintiff to proceed with the project until the final ascertainment of compensation. No land or interests in land now or hereafter owned, leased, controlled, or operated and used by, or necessary for the actual operation of, any common carrier engaged in interstate commerce, or any other public utility subject to the jurisdiction of the Illinois Commerce Commission, shall be taken or appropriated under this Section by the State of Illinois, the Illinois Toll Highway Authority, the sanitary district, the St. Louis Metropolitan Area Airport Authority, or the Board of Trustees of the University of Illinois without first securing the approval of the Illinois Commerce Commission. Except as otherwise provided in this Article, the motion for taking shall state: (1) an accurate description of the property to which the motion relates and the estate or interest sought to be acquired in that property; (2) the formally adopted schedule or plan of operation for the execution of the plaintiff's project; (3) the situation of the property to which the motion relates, with respect to the schedule or plan; (4) the necessity for taking the property in the manner requested in the motion; and (5) if the property (except property described in Section 3 of the Sports Stadium Act or property described as Site B in Section 2 of the Metropolitan Pier and Exposition Authority Act) to be taken is owned, leased, controlled, or operated and used by, or necessary for the actual operation of, any interstate common carrier or other public utility subject to the jurisdiction of the Illinois Commerce Commission, a statement to the effect that the approval of the proposed taking has been secured from the Commission, and attaching to the motion a certified copy of the order of the Illinois Commerce Commission granting approval. If the schedule or plan of operation is not set forth fully in the motion, a copy of the schedule or plan shall be attached to the motion.
