At around 06:11 hrs on 26 September 2019, an explosion occurred in an electrical equipment cupboard located in a coach vestibule as an empty train departed from Central Rivers depot. The explosion resulted in considerable damage to the vehicle interior, which was not discovered until the driver moved through the train to change ends at Birmingham New Street station.

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 be made available on our website in the next few weeks.
