Two steam locomotives moved three metres, with someone standing between them

What happened

On 8 October 2026 the Rail Accident Investigation Branch published Report 11/2026, into an incident on the Bluebell Railway in East Sussex. It happened at around 15:00 on Saturday 9 August 2025, during the railway's 65th anniversary mini-gala. A shunter - the person who couples and uncouples vehicles - was joining two steam locomotives together. They are named Fenchurch and Stepney, and they were being prepared to return to a nearby shed. While the shunter was between the two locomotives, they moved unexpectedly. They travelled about three metres, or roughly ten feet. Another member of staff on the platform stopped the movement. The shunter was not injured, but was shaken by what happened. The RAIB found a chain of causes, not a single mistake. Steam had built up in Fenchurch's cylinders and made it move, because its regulator valve was not fully closed and was letting steam through. The reverser was not in a position that would have reduced the risk of movement. And Fenchurch was not effectively immobilised, because its air brake was not fully applied. The shunter's own attempts to stop the movement did not work - because they had not been told which braking system that locomotive used. Underneath all of that, the RAIB identified a wider factor: the Bluebell Railway was not effectively managing the risks of coupling air-braked rolling stock. The RAIB made one recommendation to the Bluebell Railway: carry out a risk-based review of its arrangements for coupling and uncoupling rail vehicles.

Why this matters

Heritage railways are among the most popular days out in Britain. They carry millions of passengers a year, and they run very largely on volunteers. They are also, by definition, operating old machinery. Fenchurch was built in the nineteenth century. Stepney is of similar vintage. These are not museum pieces behind rope - they are working locomotives doing real work on real track. That combination is why reports like this one matter more than the "no injuries" line suggests. Three metres with nobody hurt is a near miss. The same three metres a second earlier, or with the shunter positioned slightly differently, is a fatality. Safety investigators treat near misses seriously for exactly this reason: they are the same event with a different ending. The finding that stands out most is not the mechanical one. It is this: the shunter had not been told which braking system the locomotive used. That is an information failure, not an equipment failure. The person doing the risky job did not have the one piece of knowledge they needed to make themselves safe. That is the kind of gap that appears in organisations full of competent, careful, well-meaning people. Which is most of them.

What the evidence actually says

The RAIB is explicit about what its investigations are for. They aim to prevent future accidents. They do not establish blame or liability. That framing is worth holding onto when reading this, because it would be easy to turn a chain of technical findings into a story about one person's error. The report does not support that reading. The shunter's actions failed because of what they had not been told. A few specifics on the mechanics, in plain terms. A regulator valve controls how much steam reaches the cylinders. If it is not fully shut, steam can keep seeping through, and pressure can build until something moves. A reverser sets the direction of travel. Putting it in a particular position reduces the chance of unintended movement - here, it was not in such a position. Immobilising a locomotive means making sure it cannot move. Fenchurch's air brake was not fully applied, so it was not immobilised. Different locomotives on the same railway can use different braking systems - vacuum or air, for example. Knowing which one you are dealing with changes what you do to stop it. Two honest limitations. The published summary does not list separate "learning points", so the general lessons above are drawn from the stated findings rather than quoted from a list. And the full report runs to 39 pages, which contains detail the summary does not - anyone with a professional interest should read the report itself rather than coverage of it.

Practical advice

For passengers, the practical takeaway is small but real. Heritage railways are safe places to visit, and nothing in this report suggests otherwise. The incident involved staff movements in a yard, not a passenger train in service. Do follow the obvious rules when you are there, though, because they exist for reasons like this one. Stay behind barriers and painted lines. Do not cross tracks except at designated crossings. Keep children close and hold hands on platforms - heritage platforms are often lower, narrower and busier than main line ones, with no platform edge doors. Assume any locomotive can move at any time, even one that looks parked. If you are visiting with a wheelchair user, or someone who walks slowly, it is worth ringing ahead. Older stations and carriages vary enormously in accessibility, and the staff will tell you honestly which stations and which trains work best. For volunteers and staff on heritage railways, the useful question from this report is a simple one to ask out loud: before you go between two vehicles, does everyone involved know which braking system each vehicle uses, and has it been confirmed that each one is actually immobilised? The RAIB publishes all its reports free at gov.uk, and they are genuinely readable. If you volunteer on a railway, Report 11/2026 is worth half an hour of your time.

What to know

On 8 October 2026 the Rail Accident Investigation Branch published Report 11/2026 into an incident on the Bluebell Railway in East Sussex. At around 15:00 on Saturday 9 August 2025, during the railway's 65th anniversary mini-gala, two steam locomotives - Fenchurch and Stepney - moved about three metres while a shunter was standing between them. Another staff member stopped the movement. The shunter was uninjured but shaken. The RAIB found that steam built up in Fenchurch's cylinders because its regulator valve was not fully closed; the reverser was not in a position that would have reduced the risk of movement; and the locomotive was not effectively immobilised because its air brake was not fully applied. The shunter's attempts to stop the movement were ineffective because they had not been told which braking system the locomotive used. An underlying factor was that the railway was not effectively managing the risks of coupling air-braked rolling stock. One recommendation was made to the Bluebell Railway: carry out a risk-based review of its arrangements for coupling and uncoupling rail vehicles. The RAIB investigates to prevent future accidents and does not establish blame or liability. The full report runs to 39 pages and contains more detail than the published summary. For visitors: heritage railways remain safe to visit, but stay behind barriers, cross only at designated crossings, keep children close on platforms, and assume any locomotive can move at any time.
