Doesn’t an alert sound if a door hasn’t closed?I agree. I think that by far the most likely explanation is that simply nobody noticed, including all staff and passengers present.
I have it too. The scene with the rubber stamps is the best - even with the Czechoslovakian steam locos.Oh yes, I remember watching the film as a student. Best Foreign Language film 1968 Oscars.

I would imagine that any alerts are on the same circuit as the interlock - so if one is obtained (correctly or otherwise) then no alert will sound, and if the interlock is bypassed (for whatever reason) any alert sound will also be suppressed.Doesn’t an alert sound if a door hasn’t closed?
Immediately as soon as they found out. No amount of PR spin will make this look good for Abellio, however trivial the cause is.
Obviously like most people I'm not going to put myself in danger in situations like this - if it were on the same side as the alarm I'd probably have waited to the next stop then used the alarm at the station, or perhaps see if it rectified itself at the next stop then use the alarm on departure if it didn't. Consider this, though, what if you wandered through the train looking for the toilet and were intent on that, then suddenly found yourself in the vestibule with the open door? What if then, as we know 321s, especially Renatus units are prone to do, the train swung violently from side to side as it crossed a set of points and that person lost their footing? The odds of all that happening are very low, but certainly not impossible. Someone who doesn't have perfect balance could easily have ended up being thrown towards an open door on a service moving at speed. If there's a way someone could fall from a train through no fault of their own, however slight the chance, it's a safety breach of the highest order. As much as open doors are the norm in other countries, it's expected in their culture, which reduces the risk quite a bit. In the UK it's just not acceptable, I don't think some people are taking this one seriously enough.

If it's the same door assy as a Class 320 - the traction & door interlock circuits use the same microswitch, which is only fitted to one leaf of the door.
What, as you indicate, could possibly go wrong with that arrangement?! Idiots.
It's a fair point - being slightly cynical, yellow fronts are primarily for the benefit of railway staff. This issue only really affects the paying punters.I find it astounding that the opinion of many posters is that "it's fine".
Seriously?
Is the general consensus that it's fine for trains in this same situation, to travel with a set of doors open?
And yet I read squabbles about yellow fronts...
How visible are recessed pocket sliding doors at the far end of a long train anyway?
This incident demonstrates that the continued safe operation of train doors is reliant on there being a robust design and suitable inspection and maintenance processes. It highlights in particular the importance of:
- specifying fastenings suitable for the environment and materials in which they are used including, when necessary, specifying and measuring an appropriate torque
- providing a means of identifying if fastenings with a safety critical function have worked loose
- identifying and implementing effective inspection and remedial actions when a safety critical defect is identified

I'm trying to work out exactly which classes they are referring to here - classes 150, 317-322, 455, and 456 make for only 9 classes. If you include the similarly doored PEPs (313-5, 507, 508) then the number is 14. Simple case of miscounting?The lessons learnt from this incident involving class 321 units are likely to have wider applicability as RAIB has identified at least 13 classes of rolling stock currently operating on the British railway network in which doors are connected to drive belts in a manner similar to the class 321 units.
