Is Leeds Neville Hill a big change? I always think back to the videos where they blitz a place in a 48-72 hour run when I think about timeframes. Just have to remember that not all projects are like that.
Ooo, good point!
The difference being HS2 will not have trains running, the benefit of new build
Indeed - so no possessions etc, making for massive improvement in efficiency and productivity for the teams.
EWR - hold my beer…
It will relieve some constraints, but not others.

On your second point, it does mean that they can work a) without having to spend time getting the equipment out and putting it back every time and b) can work during the day as you say, which is both more productive as it's light and doesn't put people off doing the job!
Must be a risk to NR electrification that HS2 will be offering daytime work which will be more attractive
The HS2 work won't be on a live railway hence opening much of the work (mast bases and mast erecting with no track in place) to much larger pool of people who don't have to have training to work on a live railway or be able to use RRVs. This was useful cost reducer in French, German and Austrian HS new build.
For what it's worth the HS2 electrification contract has gone to Colas, which doesn't clash with the current NR contracts.
None of this is esoteric work and be interesting if we had some bold leadership to put down a challenge to accelerate by 12-24mths how much money would actually be saved by avoiding all the overheads.
The workforce and equipment hours on the ground will be about the same in real terms whether it's done quickly or slowly. Going quickly avoids all the prolongation costs of keeping the management and admin running for a longer period, but incurs extra costs to mobilise more crews, more plant and more or larger bases for them to work from.
Depends on the utilisation of those resources though and i do wonder whether we strike the right balance on access on a job of this scale. I know they have some blockades you do have to wonder though given the investment in getting route knowledge built up for diversionary routes the use of more blockades would see the project delivered quicker without having to overload the supply chain.
Yes NLW extensions finished now just awaiting approval
Appreciate the update.
As far as I am aware the Liverpool to Newcastle services will except for the odd service no longer call at Stalybridge from the new timetable so will remain on diesel from Manchester to York. Some Liverpool to Hull services will be operated by Class 802s so there is a possibility that these services will operate on electric power from Liverpool to Stalybridge.
APCO at Clayton Viaduct for all 802s via Mainline, at Victoria for services via Calder Valley
Why so far from Stalybridge, they aren’t going all that fast?
You could ask the same why the APCO at York is at Askham Bar Tescos, so far from Colton
What about the Guide Bridge route (not that there is much/any bi-mode working)?
No 80x booked over Guide, but Dukinfield Viaduct is given as APCO location
