East Acton platform closure

The end date for these works have now slipped to mid-May 2022. Additionally the station will be closed in totality during Night Tube hours (01:00 - 04:45) when that resumes on 27 November.

The last train through East Acton is at 01:15, Ealing Broadway to White City, the first train is 05:18, White City to Ealing Broadway. Between juice going off and juice coming back on there's maybe a couple of hours each night for the crew to get on site, do some work then clear out again.

Is it known if the works at East Acton include the westbound platform once the eastbound is complete? 

Are you asking whether the diversion would be physically or economically possible? I suspect the answers might not be the same.

I'm sure that a possession for the eastbound only could be obtained. However, as this would require single line working between White City and North Acton this would massively reduce capacity. Further as this would require use of the middle platform at both stations for eastbound through trains you would also be significantly reducing capacity on the whole line.

Looking at Carto Metro's track map, at White City you would be able to turn some westbound trains via platform 1 and the siding, how many though I have no idea. West of the closure, the track layout is less convenient. I suspect you would run all the through trains on the Ruislip branch, turning some via P3, a mainline shunt on the eastbound before the East Acton closure, and back into P2 (I don't know if the signalling would permit this, whether the traction current sections would allow these movements while also being switched off through East Acton, and even if both were possible how many trains it could handle). If the Ealing branch was not suspended then about the best you could do would be bi-directional working of one train on the normal westbound, reversing in North Acton platform 1, perhaps with a second train in the other platform at Ealing Broadway allowing for longer layovers. You might in theory be able to run a train on the eastbound line, reversing from P3 between reversing Ruislip trains, but again I don't know if the signalling would permit this and it seems like it would have a very high potential for something to go wrong (like two trains meeting head on between North Acton station and junction). On top of that it would be very confusing for passengers and station staff, particularly at North Acton.

While I don't know what level of service could be run in this way, I strongly suspect it is going to be something that could only be viable very off peak. From memory of @moretojack talking about setting up single line one-train-in-steam working on the Hammersmith branch of the H&C following Grenfell, and assuming the procedures are similar on the Central line, this is not something you do lightly and so would effectively restrict such operation to weekends. So given everything, it's definitely simpler for everyone (staff and customers), and probably better value overall to just close the line through East Acton completely.

East Acton eastbound is finally due to reopen Monday 22 August - once again rescheduled!

East Acton eastbound looks all good for opening tomorrow. Unless something changes last minute.

I've just noticed that the Wikipedia article for East Acton is out of date regarding the platform closure, but I've not been able to find any source (other than DWS's post above) that states when the works were complete. Does anyone know of a reliable source that states this? There doesn't appear to be anything on the TfL website or in the local news.
