If it was taken out of service immediately, then how was it open for 23 minutes? That contradicts itself. Sounds like PR spin is being applied here to try and limit the damage to Greater Anglia's reputation.
No surprise there is yet another issue with Renatus trains, it is bargain bucket project which has aimed to tick as many boxes as cheaply as possible. You get what you pay for at the end of the day.
However is it me or is there nothing to back up what the headline says? The anonymous eyewitness as well doesn't seem to suggest if the train was moving or stationary. Also if there was really a technician that just happened to be there, isn't that just a co-incidence?
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.
