HS2 TBM Progress

[PLY2AYS]

My misremembering - having a senior moment!
But Mary Ann finished her Bromford drive on May 20, so definitely not rolling.
Elizabeth is the last TBM in production, until the Euston pair start up.

Have we got a date or timescale for Euston tunnelling @TBMEngineer? Or still up in the air?

Definitely states Mary Ann on the HS2 website.

Depends on which page you look at. On this page

HS2’s latest tunnel breakthrough – and the progress of our remaining giant tunnelling machines

“Good HS2 see you” ran the headline in the Sun last week as ‘Florence’ broke through at the end of her three-year-long drive under the Chilterns.

It says :
"In the midlands, Dorothy dug the first half of the relatively short Long Itchington Wood tunnel, before being turned around and sent back to complete the twin bore in March 2023.

She’s now been reconditioned, renamed Elizabeth, and is now at work on the Bromford tunnel on the approach to central Birmingham. She joined sister machine, named Mary Ann, and together they will excavate the 3.5 mile tunnels."

Up in the air
There’s talk of January launch and also talk of may launch.
but up in the air generally

A new video short has been posted, doesn't say exactly where it is, but it is alongside the Central line (there is a train going past at one point), so possibly near Greenford. It appears to show construction of a long concrete building, so possibly a tunnel ventilation headhouse, or emergency egress point

It's South Ruislip headhouse - not the linear foundation (no idea what that is), but the big boxy thing with two towers behind it, close to the railway.

Is it? I couldn’t work it out from the angle… drive that bit of line most days and I was still unsure!

That’s not confusing at all

Technically we are still 3/4 rings away from final position inside the can.
Which will be us tonight.

Fantastic
