Question to the Department for Transport:

To ask His Majesty's Government, in light of the Network Rail vegetation management review, published in October 2018, what criteria are used to approve temporary variations for vegetation management from Network Rail standards for vegetation management.

The review and potential approval for temporary variations to any of Network Rail’s standards is undertaken by a competent person (such as the standard owner or a delegated authority). The risk mitigation of the non-compliance needs to clearly be provided along with timescales on when the applicant will become compliant to the standards. The applications are at local levels and can vary. Since the October 2018 review, Network Rail has improved vegetation management training, updated the vegetation standards and deployed technology to allow it to measure compliance of the vegetation profile. This has resulted in the temporary variations being annulled and alignment to the latest version of the standard.
