Question to the Department for Transport:

To ask the Secretary of State for Transport, what the timetable is for the publication of the Rail Accident Investigation Branch's investigation into the stranding of trains at Lewisham on the 2 March 2018.

The Rail Accident Investigation Branch (RAIB) announced on 13 March that it will conduct a full investigation into the events following the stranding of trains in freezing weather, near Lewisham, on 2 March 2018.

A full investigation, including consultation of interested parties, is normally completed within 12 months. RAIB reports published in 2017 were on average published 9.8 months after an event. Each investigation will vary, depending on its complexity. In all cases, a full and public investigation report is published, including safety recommendations.

If safety issues that require immediate action are identified during an investigation, the RAIB will publish Urgent Safety Advice without delay.
