The Network Rail (Ipswich Chord) Order 2012

20.—(1) Subject to sub-paragraph (6) Network Rail must from the commencement of the construction of the specified works maintain in good repair and condition and free from obstruction any drainage work which is situated within the limits of deviation and on land held by Network Rail for the purposes of or in connection with the specified works, whether or not the drainage work is constructed under the powers conferred by this Order or is already in existence.

(2) If any such drainage work which Network Rail is liable to maintain is not maintained to the reasonable satisfaction of the Agency, the Agency may by notice in writing require Network Rail to repair and restore the work, or any part of such work, or (if Network Rail so elects and the Agency in writing consents, such consent not to be unreasonably withheld or delayed), to remove the work and restore the site to its former condition, to such extent and within such limits as the Agency reasonably requires.

(3) Subject to paragraph 23, if, within a reasonable period being not less than 28 days beginning with the date on which a notice in respect of any drainage work is served under sub-paragraph (2) on Network Rail, Network Rail has failed to begin taking steps to comply with the reasonable requirements of the notice and has not subsequently made reasonably expeditious progress towards their implementation, the Agency may do what is necessary for such compliance and may recover any expenditure reasonably incurred by it in so doing from Network Rail.

(4) If there is any failure by Network Rail to obtain consents or comply with conditions imposed by the Agency in accordance with this Part of this Schedule the Agency may serve written notice requiring Network Rail to cease all or any part of the specified works and Network Rail must cease the specified works or part of them until it has obtained the consent or complied with the condition unless the cessation of the specified works or part of them would cause greater damage than compliance with the written notice.

(5) In the event of any dispute as to the reasonableness of any requirement of a notice served under sub-paragraph (2) , the Agency must not except in a case of emergency exercise the powers conferred by sub-paragraph (3) until the dispute has been finally determined.

(6) This paragraph does not apply to—

(a)drainage works which are vested in the Agency, or which the Agency or another person is liable to maintain and is not prescribed by the powers of this Order from doing so; and

(b)any obstruction of a drainage work for the purpose of a work or operation authorised by this Order and carried out in accordance with the provisions of this Part of this Schedule.
