Are some people really stupid enough to try and board when the doors are closing?
Get a job where you have to deal with self loading freight and find out!
Passengers walking past 3or 4 closed doors because they don't want to press a button and then pushing some bodypart or other into a closing door is
very common, unlike the sense of these people.
Of course when it goes wrong it is
never their fault.

The link by Darandio leads to the full RAIB report, which reveals that there was a design fault on 185s causing a risk that a passenger's wrist could be trapped in a door on a 185 and not detected by the door interlock. This may since have been corrected but I imagine the yellow and black was considered to be a reasonably practicable mitigation of the hazard.
Of course sticking your hand in between the doors as they close is a very sensible thing to do isn't it!
The (supposed) design flaw wouldn't be an issue if some passengers weren't so stupid, but of course the laws are there to protect the stupid!

One thing I've identified as a possible problem is that the same closing tone is used whether the doors are closing automatically due to the timeout or because the train is about to depart. It would seem to me sensible to use a different tone for each case, as the meaning is different (one means "press the button and the doors will reopen", the other means "too late, stand clear"). I know there's the whistle, but that isn't universally used.
Interesting that this modification (if you'd call it that) hasn't been applied to LM's Desiros nor SWT's, all of which presumably have the same design of door.
The door is closing regardless, of course the sensible option is to press the open button so the door opens again, but that seems beyond the wit of some people.

It sounds like a cop out to me... The problem isn't that someone tried to catch the door (a natural human reaction), it's that the doors can't sense a trapped limb - it's all well and good railway staff saying you shouldn't do x, y and z - your dealing with someone who doesn't have safety training and possibly have more daily interaction with lift doors that do have some form of detection.
So you consider sticking your hand into a closing door is sensible do you?
Try it with a car/house/fridge/wardrobe/etc/etc door and see what happens.
Safety training is nothing to do with it.

How about a hilarious recorded message like "the door is closing, please do not trap your arm, leg, boyfriends sweater, hopes and dreams or goldfish in the door" like they have in Pendolino toilets? That wouldn't become irritating at all
You need to at least add pushchair, child, bag, and bike to that list.
