Please see my response to Mayor's Question 2019/6384. The Sandilands Review Steering Group is an internal working meeting to discuss non-operational issues related to the tragedy at Sandilands, including claims and legal advice. Its purpose is to enable legal advice to be given and relevant information, including updates on progress with the handling of personal injury claims to be considered and discussed.
Documents submitted by Transport for London (TfL) to the Rail Accident Investigation Branch (RAIB), SNC Lavalin, the Office for Rail and Road (ORR) or the British Transport Police were not prepared, edited or approved at the Sandilands Review Steering Group meetings. Comments were separately sought from some members of the Group at various points, but this was not done at the meetings.
