The Railways and Other Transport Systems (Approval of Works, Plant and Equipment) Regulations 1994
These Regulations make it necessary to obtain the approval of the Secretary of State before new works, plant or equipment or an alteration to any existing works, plant or equipment may be brought into use for the purposes of a relevant transport system. They replace less comprehensive provisions contained in section 25 of the Tramways Act 1870 (c. 78) and section 41 of the Road and Rail Traffic Act 1933 (c. 53).
