This item has been moved to the National Archives as RAIB has published its safety digest describing this incident. See Safety digest 10/2019.
At around 07:20 hrs on 22 August 2019, a passenger on a train travelling from London Liverpool Street to Southend Victoria reported to the driver that a door was open on the non-platform side at Hockley station. The door had been open in traffic for about 23 minutes, while the train travelled 16 miles (26 km) at speeds of up to around 80 mph (128 km/h).
We have undertaken a preliminary examination into the circumstances surrounding this incident. Having assessed the evidence which has been gathered to date, we have decided to publish a safety digest.
The safety digest will be made available on our website in the next few weeks.
