I believe it’s in use but not capable of turning 197s.
That is what is said in the internal note .
Today we saw, again, the doors open just to be immediately closed on the boarding crowds at Cardiff Central (late 2:45pm to Manchester) Surely you’d think the guards would know by now to keep their finger pressed down on the button! I’m scared someone’s going to get injured by this, because when the doors close in these particular circumstances, the object detection doesn’t seem to do anything.
turning the ASDO override switch is only required when ASDO isn’t working or at complex stations where it is not possible for ASDO to know exactly which platform the train is on and how long it is so which doors could be released.
The conductors could do 50 door release procedures a day, I’ve certainly done over 70 in a day before.
On the railway we spend a fair amount of time discussing ‘human factors’. In short, this means, we’re all human and can make mistakes, and we try to understand why and prevent them.
The act of holding the switch for only 4.5 seconds instead of a full 5 seconds before pressing the door release button could easily be done if you count just ever so slightly too fast.
Prior to the railway, I worked in manufacturing engineering and we used to use ‘Root cause and Counter measure’ to help us resolve issues.
I obviously don’t understand the system in it’s true depth (I’m by no means a CAF engineer) but ultimately, fixing the issue with the system (the train) is a better fix than hoping that conductors never get it slightly wrong.
I do agree, if it’s as violent as you say, it certainly seems a safety concern that needs to be addressed, properly!
