Another week's progress (to September 25) shows Madeleine at 4316m to go (+50m), and Karen at 4545m (+137m).
Both TBMs are past Queen's Park station and are advancing under Albert Road just south of the WCML.
Madeleine appears to be about 60m short of the Canterbury Works vent shaft site, maybe the reason for slowing.
Karen, moving at almost 20m/day, is now only 230m behind.

As of 2nd October,
Madeleine now at 4,155m to go (161m, or 23m per day)
Karen now at 4,417m to go (128m, or 18m per day)

That is nice steady progress and really good to see.

That puts Madeleine at the Canterbury Road Shaft

Came across a couple of timelapses of the TBMs being assembled and the stub tunnels being excavated, from last summer

Thanks for those videos @bib

One thing I noticed more than once is what appears to be a concrete floor being dug up and a (thicker) one being laid in its place. Is this a temporary surface being replaced with stronger to support the assembly of the TBM ?.

When both TBM's continue beyond the Canterbury Road Shaft towards Euston, how far underneath the Bakerloo Line will they be tunnelling?

Another 2 weeks like that and Madeleine will be past half way to the Euston portal...

Where do the TBMs actually finish, is it just south of Mornington Street, the next bit being a dug cut and cover section to Granby Terrace, so not at the portal ?

The portals are effectively the other side of the tracks from the Edinboro Castle pub.
