RAIB to investigate Tube train door opening incident

The Rail Accident Investigation Branch (RAIB) is investigating an incident last month on the Victoria Line that saw a new train departing Warren Street station with its platform-side doors open.

The incident happened at 5.29pm on 11 July on a northbound train comprising new stock that had been recently brought into service.

The RAIB’s preliminary examination has found that there was an issue with the automatic and manual operation of train door “sensitive edge” system that detects small obstructions by the doors.

The driver was alerted to the open doors by shouts from passengers and stopped the train with the leading car part way into the tunnel, by which time the doors had closed and there were no injuries.

The investigation will include an examination of the sequence of events leading up to the incident, the driver’s training and competence, and the implementation of sensitive edge doors on the new Victoria Line trains (including the associated control system).
