How will this partial blockade work?
Moved back a year and split into 3 phases last I heard.It was a three month partial closure from Christmas 2020 to Easter 2021.
No decisions have been taken, yet, on when the work will be done, nor the form of the closure.
Normally by closing only a fraction of the platforms in turn while they work on them. It was never likely to be a full closure over such a long period. Stuff gets misreported or exaggerated...How will this partial blockade work?

I think you mean the western tunnel in stage C, but I agree something like that is the most likely. Modern station layouts are often designed so that sections can be taken out of use for maintenance with a reduced (Sunday etc) service using the rest of the station.,@thealm
I'd expect something like this:
Stage A - Closing P0/1 and P2 to allow the platform ends to be straightened and the new throat point work that aligns with the eastern tunnel to be made operational
Stage B - Closing P3, 4/5 & 6 to allow the platform ends to be straightened / lengthened and the new throat point work that aligns with the middle tunnel to be made operational
Stage C - Closing P7, 8, 9-11 to allow the platform ends to be widened / lengthened and the new throat point work that aligns with the middle tunnel to be made operational
There are other sensible options for splitting those phases so an extra platform is available at any point in time but that leaves 6 stages
I like this a lot. It might inspire me to add 1977 before and after layouts to my document.Whilst I was visiting my mother-in-law ...
I was amazed to find I‘d posted those sketches before - but way back in 2011! I thought for a moment it was only a couple of years ago, just goes to show how time flies...I like this a lot. It might inspire me to add 1977 before and after layouts to my document.
The site of #12/13 was a loco servicing facility including a turntable suitable for smaller locos as seen on this 1913 OS:Looking at that map- when was Platform 11 restored into use? And I don't think I was aware of platforms 12, 13 & 15- I knew about there being a platform at about 14 (for trains from Moorgate)

Whilst I was visiting my mother-in-law she gave me a large card envelope which amongst other things contained an A3 publication called "Livewire" which was used to keep customers informed of electrification work and other projects pre internet age. This issue in early 1977 covered the modernisation plans for Kings Cross.
I believe the new 'car park under perpetual construction' is Google's new London HQ. https://www.kingscross.co.uk/googleNow... I knew about the connections to what are now Thameslink (you can see the York Road tunnel portal still on approach to that side of the station), now replaced by the Canal Tunnels further north. But I never knew that the platforms in the main shed were numbered the other way around! Guessing that the former suburban platforms are now under what seems to be a car park under perpetual construction (whenever I arrive) or yet more offices?

I suspect what might have led to the “car park” stuff is that it was decided to have the service yard for the Kings Cross station complex put underground to allow the air rights to be used. The sloping approach road from York Rd level is hidden within the building alongside the station throat.I believe the new 'car park under perpetual construction' is Google's new London HQ. https://www.kingscross.co.uk/google
These are fascinating. I can lose hours looking at old maps! Note the early layouts at KX and St. P both have very few platform faces under the trainsheds, but plenty of storage roads. I'm sure this was a clever ploy so they could exploit the covered space for secure rolling stock stabling while being able to add more passenger platforms later when services built up and additional carriage storage and servicing facilities became available elsewhere. Note also that originally the Hotel curve had no Kings Cross main station platform at all though it had been added in the 1890s map (there were of course platforms at the met station, which latterly inner suburban Moorgate trains stopped at as well). I think the 1950s NLS map I linked to above is broadly in agreement with the pre-1977 layout diagram. Clearly there are some changes, notably the loco servicing facility, which had been modified for diesels by then, with the turntable removed. THis is the map I am referring to:OK, so after a bit of searching I and it would give them time to bu a map based on the 1871-93 "yard to the mile" OS map. This also had a smaller scale update for 1894-96 which shows considerable expansion, but not the platform layout pre 1977

Thanks both. I did see Google's name bandied around at some point, but they have offices in Pancras Square already. I must have been confused. So much for Google MapsOffices. Google's London HQ to be precise!

We’re a stage closer to re-opening this tunnel, enabling us add an extra two lines into King’s Cross as part of #EastCoastUpgrade.
We’ve poured a 315mm thick concrete base reinforced with 300 tonnes of steel, which allows us to lay the new tracks.

Thank you for these pics- good to see progress being made at this time.Guess the designers didn't like the look of the tunnel invert.

On behalf of 'amateurs' like myself I guess you are referring to the fact that the rails are to be laid direct onto this bed of concrete rather than on sleepers. Is that not happening in other places? I can't imagine it is being done in the way it is unless that makes good sense.
Slab track is really rather awesome - saves loads of maintenance, doesn't have the ballast based geometry issues conventional track has, and means you get really nice alignment between track and OLE. It's also nicer to deal with from a drainage standpoint. It buys you a fair number of mm for the OLE too, if tunnel diameter is tight.
