Completion of HS2 logistics tunnel paves the way for high-speed line to Euston

- HS2 has celebrated the breakthrough of a tunnelling machine into its underground Old Oak Common station - marking a key milestone in plans to eventually carry the high-speed line into central London.
The tunnel boring machine (TBM) named Lydia finished its near-kilometre long journey into the station box in a move that completes the construction of the Atlas Road Logistics Tunnel.
The 853m long tunnel, which runs from the Atlas Road logistics hub, is being built to service the programme to construct the line eastwards towards Euston. It will eventually allow materials required for the Euston Tunnel to be transported to the site without clogging up local roads or disrupting work going on elsewhere at Old Oak Common station.
HS2’s London tunnels contractor, Skanska Costain STRABAG joint venture (SCS JV) constructed the logistics tunnel using a TBM made from components repurposed from a machine previously used to construct London’s Elizabeth Line. The TBM is named Lydia, a name selected by the local community, after Lydia Gandaa - a former teacher at Old Oak Common Primary School.
The TBM broke through into the eastern end of the Old Oak Common underground station box, which is currently under construction by a separate joint venture - Balfour Beatty Vinci SYSTRA (BBVS JV). Later this year, SCS JV will lower two additional TBMs into the box and assemble them ready to bring the HS2 line into Euston. Once they are in place BBVS JV will seal the box and continue to construct HS2’s super-hub station.
Over the past nine months, TBM Lydia has removed 62,000 tonnes of London Clay, all of which is sent by rail for beneficial reuse across the UK and has installed 535 concrete rings. The segments for the tunnel rings were manufactured by Pacadar UK in Kent.
A team of 100 has been working around the clock to complete the tunnel, working in shifts to operate the TBM and the above ground operations. The experienced SCS JV team have also used their expertise to develop more team members at the early stages of their careers, including apprentices and graduates for whom this was their first time constructing a bored tunnel.
The logistics tunnel will be used to deliver materials to the two Euston Tunnel TBMs, including over 56,000 concrete tunnel segments manufactured by STRABAG in Hartlepool, and take away the London Clay excavated.
Bringing in materials by road and removing the excavated spoil for the Euston Tunnel would have been logistically challenging and would have had significant impact local roads and on the work to construct the station. The logistics tunnel was the optimum solution to enable HS2 to reach Euston. Once the Euston Tunnel is complete and the railway is operational, the logistics tunnel will be backfilled.
Following the government’s Network North announcement in October, alternative funding arrangements for the delivery of Euston station are being considered. However, work is continuing with the preparations and design of the railway between Old Oak Common and Euston.
HS2 is making significant progress on the construction of the tunnels for the new railway. The Chiltern Tunnel TBMs are due to complete their work by spring, and this will be the second twin bored tunnel that has completed by HS2, alongside the Long Itchington Tunnel. Further north, HS2 is working to complete the Bromford Tunnel. In London, two further TBMs are about to launch, part of the quartet of TBMs boring the Northolt Tunnel.

HS2 should never have been sold as knocking x minutes off the journey time from London to anywhere. It's key is capacity release. More trains into places like New Street (which is full), and more freight onto rails (fewer lorries on the road). Without that capacity release, you get an ever more clogged WCML (and ECML).
Well said 🍺🍺🍺
@@ephphatha230 Thank you. I'm not saying delivery of the project has been perfect, but the concept is fundamentally sound.
I hope it isn't too expensive too. Not being much quicker than current routes and having a much higher price would just mean nobody would use it over the current routes besides wealthy or business travellers. That would defeat the point of capacity release.
@@face_thereality Fully agree there
Exactly!
Praise to the Engineering Surveyors who ensure that the Tunnel Boring Machine hits the target. Technical Excellence and professionalism.
Excellent work. Great to see another milestone achieved
Looks amazing, incredible engineering 👌
Well as usual these brilliant snapshots of some superb engineering attract the naysayers, doom merchants and do downers with their inane comments.
Its just an amazing piece of civil engineering and their closed minds just can't see it.
Preach
@@JamesJones-uu7ou My that one word must have really stressed your 2 brain cells ... 😏
How can you possibly separate the funding, design and political considerations from not just a logistical report, but one that promotes a 'rah, rah, rah' aspect of what should be a report, not a promotion?
@@1chish ??
Btw: I favour continuation to Euston, and the northern legs, but let's be honest about this, not dripping in the syrup of self-congratulation paid by shoddy financing.
I wonder what this logistics tunnel will be used for after construction ends?
Hopefully trains to watford junction won’t be as busy
Annoys me when people’s sole argument against HS2 is spending £bn to save a few minutes off journeys between London and Birmingham
Nothing to do with " saving a few minutes off the Journey between Birmigham nd London ( at least 40 mins each way actually ), it is about freeing up capacity on the WCML and Birmingham for other passenger service and freight on the WCML
Is this tunnel for the passengers to walk to Euston from Old Oak Common?
No, it's to bring construction materials from Willesden
Materials to and from the Atlas road site to reduce traffic on Old Oak Common lane and Victoria road
arr well and good could have shown abit more and what distance was done bored out
Latest emperors new clothes
How’s the budget looking?
not good 😄
Will it be repurposed after construction?
Why are you still producing videos of over engineered grandiose schemes?
Sort out UK's monetary problems at a stroke - just TAX NIMBYs AT 90% Their level of ignorance and selfishness defies belief!
HS2. How much is the British taxpayer paying for these videos?
Nothing, it not all about money.
It’s never going to get to Euston too much trouble for 5 trains a day and 63 passengers 😂😂😂😂😂
I know you think that was SO clever ......
But sadly it was just stupid.
It will be going to Euston
@@peterwilliamallen1063.. no it won't unless private investment is found & at this moment in time, there's been NO bids from any companies willing to take on the challenge & even if there were, Euston wouldn't be completed until the 2040's!
63 passengers...
Are you ok? Do you have a concussion?
@@commuterjack .. well, it certainly won't be carrying anywhere near the number of passengers that HS2 Ltd require to "break even" with a subsidy of 50/60% .. they're forecasting 600,000 DAILY between London & Birmingham but given the fact that passenger numbers on that route have been declining by 4% per year for the last decade & currently stand at approx 96,000 per day, perhaps you could explain where the "missing" 504,000 are suddenly going to materialise from?
How many more decades
Billions spent and billions more to spend by the uk government and still won’t pay a decent salary to doctors and nurses especially Northern Ireland
Our countryside being trashed
40 ancient woodlands ruined
A gravy train that falls well short of its original plan
An utter waste of money it’s an embarrassment to our country
It’s a big list of bad
Well, if you're such a smartass, what other solution do you propose to solve the capacity problem (that is only going to get worse overtime) that the WCML is facing?
I'll wait. 😊
@@commuterjack world wide birth control.
I’ll wait
@@mattgoodchild8215 I suppose everyone can dream, though I did ask for a realistic solution... still waiting.
@@commuterjack The money that has been spent on HS2 would’ve been better spent elsewhere upgrading our existing road and rail network spending more money on the NHS education immigration we could upgrade our existing rail network just like France For instance also I live amongst the carnage and destruction of our beautiful countryside which can never be replaced no matter how many trees they plant as humans we can’t keep on demolishing and taking from the Earth because future generations will have nothing but pollution and debauchery that’s all I’ve got to say
@@mattgoodchild8215adding another 4 tracks to the ECML would've cost far more than HS2
What is the point of this anymore?? It must be sole destroying to work on this project as it’s just a huge white elephant. In fact they should call the remainder of the HS2 “Nellie” as in Nellie the Elephant.
UK... England has a Change of Government in 2024. The tory party will be eradicated for their rape and plunder of the nation for 14.5 years.
You are such a Defeatist. What is said to be ABC by one UK govt, the next govt or the one after it... can make it CBA or ZYX etc.
The Number of things the tories have deliberately done in the past when they Knew they were on the way out - to Poison the Well, Harry the Land (Salt the land)... just to be Spiteful and to attempt to make the following govt have to spend MORE to get ABC back on track... ABC was still Back on track!
What the tories are doing in 2023/24 are Exactly the same as the crapola they did in 1996/97.
With a signature on a piece of paper HS2, HS3, HS4, ... HS25 can break ground and start construction day after the election.
Either you are not from/of the UK or you do not understand how the UK Constitution functions...
**soul**
🤦♂😂
@@1chish lol indeed 😂😂😂
The point of HS2 is to improve and speed up passenger train services from Birmingha, Manchester and Scotland to London Euston so freeing up the existing WCML main line for Freight and other rail services.
@@peterwilliamallen1063 yes that was the original plan, now that the government has axed the Birmingham Manchester leg, the rest of it becomes a bit pointless, we already have 2 main line routes into London from the midlands, a 3rd link would have been useful but not at the price this has cost.
Should have let the chinese built it
nah we don't have slave labour, no H & S rules, crap wages and a total disregard for the environment.
*build
China has a tendency to build tofu dreg.
@@1chish we should have those so no more white elephants like this
Colossal waste of tax payers money.
literally is not
it is sadly as it is rife with corruption, it could've been an honest 21st century railway project but instead it's just a money grab by those in charge
??
So are Motorway's, but it seems no one moans about those
I went from Stafford to London Euston. My slow train hit 112 mph ( £38 ticket)
Alternative faster train on same line £161 and 120 mph.
HS2 is a criminally insane waste of tax payers money.
You realise you didn’t travel on hs2 as it hasn’t been built yet 😂😂😂
A faster train doesn't necessarily mean more expensive. Visit Spain and you'll see mate. Privatisation of all rail services is the issue.
Was one via Banbury the other via Rugby.
