Fatal accident at Ickenham
At around 22.30 on 28 March 2025, a passenger fell from the platform onto the track at Ickenham London Underground station. They were unable to get to a position of safety. The passenger lay on the track undiscovered for around 2 minutes before being struck by an arriving train, which then stopped normally in the platform.
Following the stop, the train’s brakes automatically applied as it left the station due to part of a safety system on the train coming into contact with the passenger. Subsequent investigations into the cause of this brake application led to the discovery of the passenger, around 14 metres from where they had fallen onto the track. The passenger had been killed.
The passenger was intoxicated. RAIB’s investigation stated that CCTV showed them losing their balance and falling back against guard railings which separate the raised pavement and the road outside the station. They did not ‘appear to be behaving in a way that would have drawn any attention’. Footage inside the station showed that they fell on the stairs and a further five times before they reached platform level. Almost as soon as they got onto the platform, the passenger staggered backwards towards the track. They tried to steady themselves, but fell over the platform edge shortly before the train arrived.
Staff on duty were unaware that the passenger had entered the station in a vulnerable state, or that the passenger was on the track after they fell. There was no intervention that prevented trains entering and departing from the platform.
CCTV evidence suggests that the passenger was aware that a train was approaching after their fall and that they were probably trying to move towards the platform face and out of the path of the train. However, the underplatform recess was occupied by communication cables and this meant that there was insufficient space to accommodate the passenger and to allow a train to pass without contacting them. The train driver also did not see the passenger on the track. This may have been because they were focused on stopping theirtrain at the correct location and monitoring the platform-train interface. The contrast between the brightly lit platform and dark track bed and the passenger’s dark clothing may also have impacted the train operator’s ability to see the passenger.
RAIB identified two underlying factors. The first, a probable underlying factor, is that London Underground’s standards relating to under-platform recesses were not being complied with and were not consistent with each other. The second, a possible underlying factor, was that London Underground had not completed platform-specific risk assessments for most platforms on its network. Nor had they identified the safety benefit of some measures intended to mitigate the risk of people falling from platforms and subsequently being struck by trains.
RAIB has made three recommendations, all addressed to London Underground. The first recommends that London Underground review its standards relating to underplatform recesses to ensure that they are effective and consistent. The second recommends site-specific risk assessments for all station platforms and the implementation of appropriate risk controls. The final recommendation relates to providing operational staff with the necessary guidance and training to safeguard people under the influence of alcohol on the London Underground network.
