ConstraintFailure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
Tasks this bears on
Closing the doors
Deciding the platform is clear and the train may leave — the last thing a driver does before the train moves, and the thing that decides whether the timetable holds.
Automating✓ Evidence-backed
Where this applies
An investigation by the UK's independent rail accident investigator into a passenger whose hand was trapped in a train's doors and who was dragged along the platform. It states that in automatic train operation mode the driver remains responsible for closing the train's doors, dispatching the train and initiating its start when leaving a station, and that there is no other member of staff on the train; it finds that the train's door system did not detect the trapped hand, and recommends that the operator evaluate options including technologies to detect thin objects such as fingers and hands trapped in doors. The recommendation uses 'should' and binds no one; this is one accident on one line.
What this means
Automatic operation took over the driving but not the doors: the last check before the train moves is still a person's, and here the machine that was meant to back that person up did not see the hand.
What it does not yet show
One accident on one line; the recommendation to add detection technology is not a requirement, and it does not show how dispatch is done elsewhere.
What you can check
Open RAIB Report 01/2026 (Ealing Broadway) and find "There is no additional member of staff working on the train other than the driver".
Does it change the assessment?
No. The impact index is never moved by a single event. Nor did this record change a layer: all 1 linked judgement above already rested on earlier evidence. This one adds to them.
