HS2 TBM Progress

[PLY2AYS]

So about 16 weeks at current rate of progress.

Makes it seem a lot, lot sooner when you put it into an approximate timescale!

Downline TBM in NTE is now approaching the shaft and we expect breakthrough Friday.
We shall hit the can tonight, with slow progress for the past few shifts due to the foam concrete

Northolt East TBMs were updated today for May 30 (ie a week ago) for 20 days from May 10.
Emily is at 5516m (+93m), Anne at 5482m (+463m).
So Emily has moved slowly (4.6m/day) towards the exit portal and had 33m left, while Anne has moved quickly (23m/day) and was only 18m short.
Both TBMs are now poised to enter the exit "can" at the Greenford Way shaft, and as has been posted by TBMEngineer, Emily might finish today.

Superb.

Any news on what the next project for the TBMs are? Or whether they’re being repurposed for the tunnels for Euston approaches?
Saw recently that one’s already gone (in the process of going) back to Germany.

Euston has new TBMs and most of the parts have been on site for a while. As covered a few pages ago assembly of the Euston TBMs has been paused to prioritise OOC station construction for the time being.

Just to clarify, the Euston tunnels TBM's ‘Karen’ and ‘Madeleine’, are already assembled and in position at the eastern end of the OOC station box, almost ready to start up, once approval had been given to start tunnelling.

There's no information out in the public domain regarding how far the logistics tunnel has been prepared for spoil extraction and other tunnelling support services.

Once the conveyor system from Victoria Road has been dismantled, I expect it will be cut back and linked into the Atlas Road logistics site and the logistics tunnel.

Officially broke through last night into the shaft and can. A few more rings to push the shield fully into the can.
But Shift A broke through last night.
There will be an official SCS photo. (But they didn’t break through

They are taking some bits from Emily back to Germany. Rest is getting scrapped
