SCHEDULE 9 PROTECTIVE PROVISIONS

PART 4 FOR THE PROTECTION OF NETWORK RAIL
37. (1) If any permanent or temporary alterations or additions to railway property are reasonably necessary in consequence of the construction of a specified work or a protective work, or during a period of 24 months after the completion of that work in order to ensure the safety of railway property or the continued safe operation of the railway of Network Rail, such alterations or additions may be carried out by Network Rail and if Network Rail gives to the undertaker reasonable notice of its intention to carry out such alterations or additions (which must be specified in the notice), the undertaker must pay to Network Rail the reasonable cost of those alterations or additions including, in respect of any such alterations or additions as are to be permanent, a capitalised sum representing the increase of the costs which are expected to be reasonably incurred by Network Rail in maintaining, working and, when necessary, renewing any such alterations or additions.
(2) If during the construction of a specified work or a protective work by the undertaker, Network Rail gives notice to the undertaker that Network Rail desires itself to construct that part of the specified work or the protective work which in the opinion of the engineer is endangering the stability of railway property or the safe operation of traffic on the railways of Network Rail then, if the undertaker decides that part of the specified work or the protective work is to be constructed, Network Rail must assume construction of that part of the specified work or protective work and the undertaker must, regardless of any approval of the specified work or protective work in question under paragraph 33, pay to Network Rail all reasonable expenses to which Network Rail may be put and compensation for any loss which it may suffer by reason of the execution by Network Rail of that specified work or protective work.
(3) The engineer must, in respect of the capitalised sums referred to in this paragraph and paragraph 38(a), provide such details of the formula or method of calculation by which those sums have been calculated as the undertaker may reasonably require.
(4) If the cost of maintaining, working or renewing railway property is reduced in consequence of any such alterations or additions, a capitalised sum representing such saving must be set off against any sum payable by the undertaker to Network Rail under this paragraph.
