legacy CSDE equipment (Bakerloo/Piccadilly/sub-surface manual) gives around 1.0m of tolerance, ATO/CBTC/TBTC much less.
It was done on Thameslink but they botched it up and they didn't line up with where the doors actually stopped.
Seems to work for me every evening.
They've probably moved them then.
Possibly (I just dont know!)
However it is also the case that most trains are now driven by ATO through the core, and I guess observed stopping positions are a little tighter.
Those are survey targets, used to check if the ground is shifting.There are also strange black and white squares that don't seem to line up with anything.
How very interesting, thanks for that!Those are survey targets, used to check if the ground is shifting.
The markings at Canary Wharf Jubilee Line have gone now, but the formalised queueing at each doorway continues, doubtless at first by inertia, then as office staff changed over they just followed the convention.
Extensive platform markings were trialled at Kings Cross St Pancras back in 2017. It wasn't successful.
Interesting. When I first looked at that, it said to me DO stand in the green bits.
Separately from the green lanes trial on the Victoria Line, I believe that specifically the southbound Northern Line platform at King's Cross St Pancras has (or at least had up until earlier this year, according to Youtube videos) longstanding yellow hatchings at the door positions, as seen in this screenshot from a video from 2017:I would have thought a simple yellow hatched area with a few signs and arrows (similar to the Hong Kong example in the opening post) would have worked much better.
They are where the doors are. The train in the screenshot is not fully berthed.You want them where the doors are so people stand away from them.
I believe there are several Underground stations with "Mind the Gap" written along the platform edge at odd spacings, which turn out to be the door positions, as seen in this screenshot from another video showing the Northern Line at Moorgate:
