At around 08:00 hrs on Thursday 12 March 2015, a passenger fell beneath a train after being dragged along the northbound platform of Clapham South station, in south London. She was dragged because her coat had become trapped between the closing doors of a London Underground Northern line train.
The train had stopped and passengers had alighted and boarded normally, before the driver confirmed that the door closure sequence could begin. The train operator, in the driving cab, started the door closure sequence but, before the doors had fully closed, one set encountered an obstruction and the doors were reopened. A passenger who had just boarded, and found that the available standing space was uncomfortable, stepped back off the train and onto the platform, in order to catch the following train. The edge of this passenger’s coat was then trapped when the doors closed again and she was unable to free it.
The trapped coat was not large enough to be detected by the door control system and the train operator, who was unaware of the situation, started the train moving. While checking the platform camera views displayed in his cab, the train operator saw unusual movements on the platform and applied the train brakes. Before the train came to a stop, the trapped passenger fell to the ground and then, having become separated from her coat, fell into the gap between the platform and the train. The train stopped after travelling about 60 metres. The passenger suffered injuries to her arm, head and shoulder, and was taken to hospital.
As a result of this accident, RAIB has made one recommendation, addressed to London Underground, seeking further improvements in the processes used to manage risks at the platform-train interface.
RAIB has also identified one learning point for the railway industry, relating to the provision of under platform recesses as a measure to mitigate the consequences of accidents where passengers fall from the platform.
Response to recommendations:
- RAIB will periodically update the status of recommendations as reported to us by the relevant safety authority or public body
- RAIB may add comment, particularly if we have concerns regarding these responses.
