Sentinel Scheme Rules updated V3 – first issued June 18, compliance July 18

Posted in Communications Rules

The Sentinel Scheme Rules have been updated. Make sure you are aware of the changes.

On Monday 11 June 2018 version 3 of the Sentinel Scheme Rules was published with a compliance date of Monday 9 July 2018. Under section 2.2 Primary Sponsors, sub section D please be aware of the changes listed below and update those individuals who have a contract of sponsorship.

The current version of the Sentinel Scheme Rules was issued in June 2015; this was to allow the introduction of Transport for London (TfL) into the scheme.

Since then we have been working with TfL to make the rules applicable across both infrastructures and no longer refer to only Network Rail.

Changes have been made following on from feedback, Formal Review panels and appeals. The changes were reviewed and amendments recommended by Infrastructure Safety Leadership Group (ISLG), Rail Industry Contractors Association (RICA), Network Rail and Transport for London amongst others.

Please read the attached document for details of the changes being made to the Sentinel Scheme Rules.
