Corporate memory matters
RSSB’s Tom Waghorn recalls an incident from 2016, which had a particular resonance for him professionally… and personally
It is 7 August 2016, and I’m sitting on the steps of Horsted Keynes signal box during a quiet spell on a warm summerafternoon. At the time, I was volunteering as a signaller at the Bluebell Railway. During this lull, a message appeared in a social media group chat. A friend was discussing an emergency response to an incident at Balham. Reports suggested that a passenger had gained access to the guard’s area of a Class 442 operating a Gatwick Express service. The passenger had leaned out of the window and struck a signal gantry while the train was travelling at around 60 mph. Comment from the group surrounded how unusual this was. It seemed quite likely the victim could only be a railway enthusiast.
Group discussion faded as the evening passed, with little confirmed information emerging beyond speculation in newspapers. When I woke for work the next day, I had received an email informing me of the death of a mutual friend, Simon Brown. The email initially suggested he had died in a car accident. Shortly afterwards, Simon’s mother called. She confirmed that he was, in fact, the person involved in the railway incident reported in the media.
As further details of the incident emerged, Simon’s family understandably wanted answers. They questioned whether responsibility lay with the infrastructure manager for allowing a structure to be positioned so close to therunning line. Or did it lie with the train operator, regarding risk assessments of trains operating on the route?
The response by frontline staff was commendable. Every effort was made to prevent the incident from becoming fatal, but sadly this was not possible. Simon was removed from the train at Wandsworth Common station and transferred into a private ambulance. Evidence later presented at the inquest indicated that he would have been unaware of events followingthe impact.
The reasons are complex, and the exact motivations behind Simon leaning out of the window will never be known. My personal theory is that Simon was deeply committed to his work and may have chosen to stand in the guard’s area while travelling to work. It is possible he noticed or heard something unusual and instinctively looked out of the already open droplight window.
Several technical and procedural factors contributed to the circumstances. Despite refurbishment for Gatwick Express service, Class 442s retained droplight windows in the centre carriage, with no physical mechanism preventing passengers from fully opening them or leaning out.
Additionally, there was reduced clearance between the structure and the vehicle’s swept path. Due to the age of the gantry, Network Rail was unable to provide original design specifications to confirm compliance with historical clearance standards.
Govia Thameslink Railway’s safety case for operating Class 442s on the London–Gatwick route relied partly on successful empty-train trial runs, the units’ previous 17-year service on the Wessex route, and their listing as cleared stock within the Sectional Appendix. While structural clearances were considered, assessments focused on potential vehicle impacts rather than the risk posed by passengers leaning from windows.
RAIB also identified factors that may have delayed the emergency response. The passenger communication system on the train lacked a driver override function, causing the train to stop outside Balham station when activated. Once the driver understood the nature of the emergency, he informed the signaller but was unable to move the train until the system was reset. The train subsequently continued to Wandsworth Common, where evacuation began.
Separately, a dedicated emergency telephone line used by the incident controller at Three Bridges Rail Operating Centre had been incorrectly connected, causing an emergency call to divert to a non-emergency call handler. The handler, unprepared for such a situation, required 7 minutes to correctly categorise the call and dispatch emergency services. Although the call was eventually classified as immediately life-threatening and a paramedic was sent, navigation errors initially directed them to the wrong side of Wandsworth Common station. This resulted in their arrival approximately 25 minutes after the accident. Medical evidence later confirmed that this delay would not have improved the outcome.
The immediate grief felt by those who knew Simon has softened over time, though he remains far from forgotten. Temporary safety modifications were introduced to the ‘442s’ prior to their withdrawal, which came less than a year after the incident. The replacement Class 387s do not feature droplight windows. The gantry involved has since been removed as part of a wider resignalling programme. Training for emergencies is inherently challenging as many scenarios are difficult to replicate or even anticipate. The calm and professional response demonstrated by those involved is testament to the training, preparation, and commitment that railway staff bring to their roles every day.
Today, the case is cited in UK rail safety discussions as an example of the limits of ‘personal responsibility’ in public transport and the necessity of design-based safety controls. It forms part of the broader safety framework in which operators are expected to anticipate predictable human behaviour— especially in environments where a moment’s curiosity can have irreversible consequences.
