Paragraph 13

If at any time after the completion of a specified work, not being a work vested in Network Rail, Network Rail gives notice to the Promoter informing it that the state of maintenance of the specified work appears to be such as may adversely affect the operation of railway property, the Promoter shall, on receipt of such notice, take steps as may be reasonably necessary to put the specified works in such state of maintenance as not to adversely affect railway property.
