At around 05:51 hrs on 6 November 2017, the rear coach of a passenger train derailed while it was travelling at around 19 mph (31 km/h). This occurred shortly after the train had left Wimbledon station with approximately 146 passengers on board. The accident caused several minor injuries to passengers and considerable infrastructure damage.
We have undertaken a preliminary examination into the circumstances surrounding this accident. Having assessed the evidence which has been gathered to date, we have decided to publish a safety digest.
The safety digest will shortly be made available on our website.
