An investigation has been launched after a rail passenger was forced to run several metres along the platform with his hand trapped inside the doors of a moving train.

The passenger, who was trying to board an Elizabeth line service just after midnight, had his hand caught in the door as it began to depart, the Rail Accident Investigation Branch (RAIB) said on 24 December.

He was then forced to run alongside the moving train for several metres until a member of railway staff who was working on the platform at Ealing Broadway station, west London, pulled him away.

Nearby passengers alerted the driver, and the train stopped after moving about 17 metres. The passenger is reported to have sustained minor injuries, the RAIB confirmed.

The “trap and drag” incident, which took place on 24 November around 12.07am, is the latest case of a rail passenger having to run alongside trains with their hand or arm trapped in doors at stations. Previous incidents took place at Enfield Town, north London, in July; Seven Sisters, north London, in June 2022; Bushey, Hertfordshire, in March 2018; and Newcastle Central in 2013.

The RAIB investigation will consider factors such as if anything influenced the actions of those involved, and how risks associated with passengers boarding and alighting Elizabeth Line trains are managed. It will publish its findings, including any recommendations to improve safety.

Elizabeth Line services are operated by MTR Elizabeth line under a concession from Transport for London. The Guardian has approached both organisations for comment.
