4.—(1) Where any street is stopped up under article 9 (stopping up of street), any undertaker whose apparatus is in the street has the same powers and rights in respect of that apparatus as it enjoyed immediately before the stopping up, but nothing in this paragraph affects any right of Network Rail or the undertaker to require the removal of that apparatus under paragraph 6(2) or the power of Network Rail to carry out works under paragraph 8.
(2) Network Rail must give not less than 28 days’ notice in writing of its intention to stop up any street under article 9 to any undertaker whose apparatus is in that street.
