Clause 52 gives powers to apply the Act to further high-speed rail works; possibly the sort of works that the hon. Member for Kilmarnock and Loudoun referred to. It allows the use of a Transport and Works Act 1992—TWA—order to gain the necessary provisions for extensions or additional works relating to phase 1 of HS2, beyond the works outlined in the Bill. That relates to relatively minor transport works, such as an additional track to connect to rail sidings. This power would not be used to promote future phases of HS2. Those would be subject to the hybrid Bill process. A TWA order cannot apply the provisions of the Bill that enable the Secretary of State to extend the time limit for the exercise of compulsory purchase powers or the provisions relating to listed buildings or ancient monuments.
