The London Overground (Barking Riverside Extension) Order 2017

11.—(1) In this paragraph—

“EMI” means, subject to sub-paragraph (2), electromagnetic interference with Network Rail’s apparatus generated by the operation of the authorised works where such interference is of a level which adversely affects the safe operation of Network Rail’s apparatus; and

“Network Rail’s apparatus” means any lines, circuits, wires, apparatus or equipment (whether or not modified or installed as part of the authorised works) which are owned or used by Network Rail for the purpose of transmitting or receiving electrical energy or of radio, telegraphic, telephonic, electric, electronic or other like means of signalling or other communications.

(2) This paragraph applies to EMI only to the extent that such EMI is not attributable to any change to Network Rail’s apparatus carried out after approval of plans under paragraph 5(1) for the relevant part of the authorised works giving rise to EMI (unless TfL has been given notice in writing before the approval of those plans of the intention to make such change).

(3) Subject to sub-paragraph (5), TfL must in the design and construction of the authorised works take all measures necessary to prevent EMI and must establish with Network Rail (both parties acting reasonably) appropriate arrangements to verify their effectiveness.

(4) In order to facilitate TfL’s compliance with sub-paragraph (3)—

(a) TfL must consult with Network Rail as early as reasonably practicable to identify all Network Rail’s apparatus which may be at risk of EMI, and must continue to consult with Network Rail (both before and after formal submission of plans under paragraph 5(1)) in order to identify all potential causes of EMI and the measures required to eliminate them;

(b) Network Rail must make available to TfL all information in the possession of Network Rail reasonably requested by TfL in respect of Network Rail’s apparatus identified under paragraph (a); and

(c) Network Rail must allow TfL reasonable facilities for the inspection of Network Rail’s apparatus identified under paragraph (a).

(5) In any case where it is established that EMI can only reasonably be prevented by modifications to Network Rail’s apparatus, Network Rail must not withhold its consent unreasonably to modifications of Network Rail’s apparatus, but the means of prevention and the method of their execution must be selected in the reasonable discretion of Network Rail, and in relation to such modifications paragraph 5(1) has effect subject to this sub-paragraph.

(6) If at any time prior to the commencement of operation of any part of the authorised works regardless of any measures adopted under sub-paragraph (3), the testing or commissioning of the authorised works causes EMI then TfL must immediately upon receipt of notification by Network Rail of such EMI either in writing or communicated orally (such oral communication to be confirmed in writing as soon as reasonably practicable after it has been issued) immediately cease to use (or procure the cessation of use of) TfL’s apparatus causing such EMI until all measures necessary have been taken to remedy such EMI by way of modification to the source of such EMI or (in the circumstances, and subject to the consent, specified in sub-paragraph (5)) to Network Rail’s apparatus.

(7) In the event of EMI having occurred—

(a) TfL must afford reasonable facilities to Network Rail for access to TfL’s apparatus in the investigation of such EMI;

(b) Network Rail must afford reasonable facilities to TfL for access to Network Rail’s apparatus in the investigation of such EMI; and

(c) Network Rail must make available to TfL any additional material information in its possession reasonably requested by TfL in respect of Network Rail’s apparatus or such EMI.

(8) Where Network Rail approves modifications to Network Rail’s apparatus under sub-paragraph (5) or (6)—

(a) Network Rail must allow TfL reasonable facilities for the inspection of the relevant part of Network Rail’s apparatus; and

(b) any modifications to Network Rail’s apparatus approved under those sub-paragraphs must be carried out and completed by TfL in accordance with paragraph 6.

(9) To the extent that it would not otherwise do so, the indemnity in paragraph 15(1) applies to the costs and expenses reasonably incurred or losses suffered by Network Rail through the implementation of the provisions of this paragraph (including costs incurred in connection with the consideration of proposals, approval of plans, supervision and inspection of works and facilitating access to Network Rail’s apparatus) or in consequence of any EMI to which sub-paragraph (6) applies.

(10) For the purpose of paragraph 10(a) any modifications to Network Rail’s apparatus under this paragraph are deemed to be protective works referred to in that paragraph.

(11) In relation to any dispute arising under this paragraph the reference in article 45 (arbitration) to the Institution of Civil Engineers is to be read as a reference to the Institution of Electrical Engineers.
