3.—(1) Where under this Schedule Network Rail is required to give its consent or approval in respect of any matter, that consent or approval must not be unreasonably withheld or delayed but may be subject to reasonable conditions (while recognising that the engineer has sole discretion in matters relating to safety) and is subject to the condition that Network Rail complies with any relevant railway operational procedures and any obligations under its network licence or under statute.
(2) In so far as any specified work or the acquisition or use of railway property is or may be subject to railway operational procedures, Network Rail must—
(a)co-operate with the Company with a view to avoiding undue delay and securing conformity as between any plans approved by the engineer and requirements emanating from those procedures; and
(b)use its reasonable endeavours to avoid any conflict arising between the application of those procedures and the proper implementation of the authorised works under this Order.
