Aren't there issues because the door close control closes both sides at the same time on some stock, so safe despatch is complicated.
Another LU one - at Barking Platform 2 I've seen the trains open their doors on both sides on a few occasions.

I think they always do. Nipping through a District Line train can be the quickest what to get from the Gospel Oak to C2C platform.

Complicated, why so?
I seem to remember in the distant past that they did used to use both sides, even with 455s (slamdoors for sure!). I think a radio was used by a dispatcher on one side to communicate with dispatcher on the 'main' side who would then use a bat
Preston has a double-sided bay (always advertised as 3c),
When I have been there the driver has initially opened up on the left hand side when arriving from the west, thus giving passengers wanting to be further east cross platform interchange to Debden / Epping trains. When passengers have had chance to alight, these doors are closed and the doors at the other side opened, so that access to the train is from the main westbound island platform.How about Loughton on the LU Central Line?
At Canary Wharf the opposite sides of the same track have different platform numbers. Does anyone know why, and is it true at any of the other tracks with platforms both sides?
What is the alternative? Unless you start to refer to them as 'tracks' surely any other method would just cause confusion?
DLR Tower Gateway is the same, plats 1 and 2 either side of a single track. The station was rebuilt a few years ago to this pattern from the former island with 2 tracks. Theoretically passengers should alight on the north side (plat 1) and wait to board on the south side; this latter works well normally, but because the doors are released simultaneously on both sides on arrival, together with rather unclear PA announcements, equal numbers disembark on both sides, which somewhat loses the point of the quite expensive remodelling.I've never (in the UK) seen different platform numbers on opposite sides of the same track except at Canary Wharf (where ironically enough they do open doors both sides).
Several stations on the Glasgow Suballway have this feature. Partick, Govan and St Enoch from memory.
Unlike the DLR, whose under-running conductor rail makes this not an issue, I've always been a bit questioning about Underground platforms like this, the new Stratford westbound one in particular, with the live rail just a footslip beneath you as you board - which is of course why every other station always has the positive rail on the opposite side to the platform.
Yes the DLR does have short shields (like bits of it's conductor rail cover) at stations. I've actually seen trespassers cross the tracks between platforms and use these as steps up :roll:The DLR does of course have upward-facing shoes on both sides of the train, which are all live whenever any of them is touching the live rail. However there appear to be some shields attached to the platform walls, presumably at the places where the shoegear stops. I doubt it would be possible to position a shield above a bottom-contact third rail for the same purpose without fouling the gauge of passing trains.
Hence this is probably a case of a risk with no practicable mitigation, which is tolerable and just has to be tolerated.

For the likes of Stratford I have wondered whether an opposite of the system used at Wimbledon and Richmond would be possible. The Underground is normally 630v, supplied at +420v in the outer positive rail and -210v in the centre negative rail. On those sections shared with NR it's +630v in the outer and 0 in the centre, bonded to the running rails which of course are also zero and the return path for the NR trains. As far as the Underground train is concerned it sees a difference of 630v whatever. So could Stratford platform be supplied with -630v in the centre and zero in the outer conductor rail? Is the insulation of the centre sufficient? Possibly a traction electrical engineer will be along to say whether this is practical or a nonsense.
Isn't this what is done at Putney Bridge and Gunnersbury on the District, and Queens Park on the Bakerloo?I can't say if it is nonsense but it would need a coach-length gap in the conductor rails at each end, so that shoes that are electrically connected to each other couldn't be touching the different configurations at the same time.

The one at Norwood Junction is a headache as I experienced last year as the doors only open on one side, causing me to miss that train and wait in a not pleasant area.
I find it odd why you would wait on platform 2 for a train when not a single one is advertised as boarding from there, only 1 or 3.
And even after the football - which I guess is why you are down there - there is a fast train every 10 mins or so from plat 3 and one about evey 6 mins from platform 1 so you didnt have to wait long. And its not that bad an area at all.
I havent seen anyone say eastbound on the central line yet , or did I miss it.
Yes, Norwood Junction is not a problem as there is nothing from platform 2. I remember when slam-door stock was used, the option for either platform existed.
When you say "eastbound on the central line" - where do you mean? I have already mentioned White City, and Loughton has also been mentioned.
yes, platforms 3/3A at Stratford have been mentioned a couple of times already.
Cockfosters on the Piccadilly Line though hasn't been mentioned, like Uxbridge it has the potential for doors to be opened on both sides of the train but they are only opened on one side.
I said at stratford however I did mean the westbound not east, my compass was upside down
