6.—(1) No person has a right of objection to the delineation of land as railway area in any plan or map prepared under section 5(1) or to any amended plan or map or substitute plan or map prepared under section 5(5). (2) The fact that land is so delineated in any plan or map prepared for the purposes of section 5(1), or in any amended plan or map or substitute plan or map prepared under section 5(5), as being within the railway area is for all purposes conclusive evidence that —(a) the land may be required to be acquired; or (b) rights in, under or over the land may need to be exercised by the LTA or a concessionaire or licensee under this Act, for the purpose of or incidental to constructing, maintaining, operating and improving the railway infrastructure or managing the railway assets of, or providing network services or train services on, a cross‑border railway subject to this Act. (3) Such of the lands shown in any plan or map prepared under section 5(1), or any amended plan or map or substitute plan or map prepared under section 5(5), as within the railway area are to be treated as land required for a public purpose within the meaning of the Land Acquisition Act 1966.
