Final breakthrough for HS2’s longest tunnel
Вставка
- Опубліковано 20 бер 2024
- The second giant boring machine (TBM) building HS2 under the Chiltern Hills broke through at the tunnel’s northern portal, completing a journey that began in June 2021.
Named Cecilia, the TBM has driven for 10 miles underground to join twin sister machine - Florence. She arrived at the site near the Buckinghamshire town of Wendover on 27 February, after completing her adjacent tunnel drive.
Between them, the two 2,000 tonne machines have built the twin bore tunnel at depths of up to 80 metres and excavated three million cubic metres of chalk. Each machine operates like an underground factory, able to excavate the tunnels and line them with 56,000 pre-cast concrete tunnel segments, grouting them into place and moving forward at an average speed of 16 metres per day.
When HS2 is operational trains will travel through the Chiltern tunnel - the line’s longest - at speeds of up to 200mph, helping to almost halve journey times between Britain’s two largest cities.
The new high-speed line will relieve traffic the West Coast Mainline, freeing up space for more local services on the most crowded part of the important Victorian route. It will almost double rail capacity between London and the West Midlands, providing a more reliable service and driving economic growth.

Nearly 3 years continuously chewing through the ground and 16km twin tunnels!! - huge achievement - will serve people for decades to come 🙌 Well done to all involved
Hopefully a lot longer than a few decades! Although see Woodhead tunnels . 🙂
Within a decade of opening, (in about 50 years time given the current rate of progress), it'll be nothing more than a glorified cycle path.
HS2 is an environmental disaster of epic proportions & Britain's biggest infrastructure mistake in half a century.
Well done everyone at HS2.
Nice video. I really like that start & finish videos are made, which gives a good picture of how things are going.
Now leys get the Euston psrt complete and then it might start looking like a railway ,and hopefully the extension from Birmingham to Manchester and leeds .
Hear hear
Euston is history & Labour have already stated they have no plans whatsoever to complete the Birmingham - Manchester line which is excellent news as HS2 is an environmental disaster of epic proportions & Britain's biggest infrastructure mistake in half a century.
@@CRIMSONANT1 Our resident HS2 troll bot is here again, just like on every other video, spouting uninformed and ignorant nonsense. [yawn]
By the way, what was the other infrastructure mistake in the previous half a century?
@@mrglide7078 .. what's "ignorant" about it?
In a January interview, Starmer confirmed that when (not if), Labour win the next election, they WON'T reinstall the Birmingham - Manchester line as "it wasn't possible to do as the government had blown the budget & contracts have been cancelled".
You really need to pay more attention & keep up with current events 😉
Yep. Ultimately high speed rail needs to be extended all the way to Edinburgh and Glasgow, as the entire point of HS2 is to move InterCity trains off of the existing mainlines, so that the existing mainlines can be repurposed to take more commuter trains and more freight services (both of which travel at around the same speed).
I would suggest though, that we take the unwarranted pause in HS2 development as an opportunity to improve the plan from a bunch of branches that all point towards London and replace them with high speed through stations in every city on the Western leg and Eastern leg that we get added back into the plan.
We just spend a considerable number of decades delaying the Crossrail plan to connect the railway terminals at Paddington and Liverpool Street. It doesn't make sense for our high-speed network to make the mistake of repeating the short-sightedness and scatter more terminal stations in English cities, when we know that the cities will become more successful and eventually render all those terminal stations obsolete.
The line into London could have instead been built as a line through London, with a station similar to the Old Oak Common design in the heart of London an onward connection to HS1 and land on London not being dedicated to trains that park there waiting for a new crew. The same could have been done at Birmingham Curzon Street. The site was big enough to have sunk a box in the ground large enough for TBMs to pass under Birmingham and then carry on.
There must be at least one big public park, in the centre of every large city in England, that could temporarily be converted into a construction site, so that an InterCity station, with connections to local metro services could be dropped into the city and so that obsolete mainline terminal stations can be replaced. We will have to "Crossrail" our way through cities, as they grow. So our switch from mixed traffic trains to high-speed rail and a switch to local train services optimised for local people, should really move in the logical direction and not repeat the short-sightedness of Victorians.
Fantastic job! Well done to Cecillia and her team! 👏👏👏
The team are Muppets
Great work all. Fantastic project, tremendous breakthrough. Well done everyone
Fantastic job and you are setting the standards for how HSR should be built in the future
Well done!!!
wow.. I hope the train will be much faster.
For the amount spent it wont be. Fares will be more expensive to save 20 mins...Better off making current lines fares cheaper. So everyone doesn't need to live in London or near London
Well done to HS2 for finally completing HS2s longest tunnel also anybody correct me if I’m wrong but what I have heard is this is the chiltern tunnel which is the longest tunnel of HS2 which will be 10 miles long?
Yes this Tunnel is 16km long which = 10 miles
Congratulations 👏 🎉 well done to everyone involved in this boring job, and to have the tunnel vision to see the light at the end of the tunnel!!
P.S I wish I could see it and inside the tunnel and vent shafts in person to really appreciate and understand what has been achieved.
I am a bit concerned worried about the beautiful long viaduct though if I understand it right that segments load kept together by cables inside if so worried about the maintenance and longevity of this, in case it leads to a disaster in the future, please correct me if I am wrong about this?
I have to say, even with the astronomical cost, impressive, 10 mile tunnel. This will have played a very big part in the cost.
Well done, wish the government would think longer term with how to finance the entire project though. Not quite there really.
Great job!
Great Video!
And to think that when those machines started digging, the tunnels were going to be carrying trains all the way to Manchester and Leeds on high-speed lines... Oh how times have changed, unfortunately.
The trains are still going to Manchester. North of Lichfield they will switch to the WCML the rest of the way
@@mrglide7078 Yeah, but they're not going to Manchester .
@@mastertrams Yes they will. They will share the WCML track with regular trains all the way to Piccadilly
@@mrglide7078 Sorry, that was a formatting error. Apparently typing in bold means it doesn't get posted to UA-cam. Here's what I actually wrote:
"Yeah, but they're not going to Manchester on high-speed lines."
You know... Because they'll be switching to conventional lines midway.
@@mastertrams no high speed line unfortunately
Reminds me of the sand worms on dune
What an incredible achievement! Can't wait to see trains using it to head to Manchester and Leeds on new dedicated lines ...oh wait
That stuff will get restored in the future. But it is a shame that our current prime minister has deliberately "salted the earth" by ordering the quick sale of land, at a loss, so that any plans by another government to restore those sections can be claimed to be "too expensive". To work against the needs of the Midlands, and North England and Scotland, just to cock-block the Labour Party is totally shameful.
It's one thing for political parties to have a different opinion about "what is best for Britain" but actually damaging the economic future of the Midlands, to prevent the Labour Party from reversing funding cuts borders on treason.
Amazing work!
Now start tunnelling under the blue mountains to open up the central west of NSW
Fantastic job team :D
did they finally manage to find a government minister willing to stand in front of the cameras ? the last few metres seemed to take months.
If Boris was in power, he would have been there at the first tbm breakthrough… and probably the second one too! However covid etc
How many breakthroughs were there for this tunnel?
Hi, there were two Tunnel Boring Machines (TBMs), Florence and Cecilia, used to create the 10-mile long tunnel. The first breakthrough took place last month, you can watch it here: ua-cam.com/video/2Zzmj9gmGxU/v-deo.htmlsi=NbilUyTCYhCo5vP1
My, that's a big one.
Waheguru Ji
When will the trains be running. I can't be too many more years given the contractors commenced design in 2017. 2-3 more years?
2027-2028 they start running tests and the trains get made, 2029-2031 passenger service starts
They need to get a move on to be running tests in 4 years time. Just in the route from the North Portal to Wendover, there are 2 viaducts, 2 over bridges, trackbed & track, electric supplies, signal systems, noise barriers & fencing etc to do. I doubt they will manage that in 4 years
It's now 2024. If the civil works take three more years and the railway contractors take say 3 years with 2 years of testing then passenger trains should start in 2031 at the earliest. Major projects often run late so add a couple of years on this, so 2033?
@@carguyuk7525 As long as the Government stop fiddling with the cost and arguing we could see the line up and running by 2030.
Given all the extra work that has taken plsce, future unknown work. government dithering and currently an unknown solution to Euston it will be a miracle if the project is finished by 2033. More likely to be late 2030's.
Probably the most expensive hole in the world
Can you build this to Newcastle please 🙏 don't stop at Manchester
Should have started HS2 in the Northern City's first then see if it would have been abandoned then 🤷♂️
The dying question is why should HS2 of started in the Northern Cities first and what is more important about the Northern Cities than the West Midlands combined area and the UK's Second City Birmingham from where HS2 is being built Nothwards and South.similtaniousely, plus HA2 has not been abandoned.
@@peterwilliamallen1063 The answer would be- they won't cancel it if the London section wasn't finished 👍
@@nickroach2791 The thing is none of HS2 is being cancelled full stop, and again what is so important about the North that HS2 should of started there !!
No wonder it's so expensive : there were hundreds of people standing around, doing no work.
It will be a lovely cycle route.
What cycle all the way from Birmingham to London with a 200mph train running over you. Good luck with that 🤪
@@scottpeacock5492 why, 'tis the wit of Chaucer mounted with the faculties of Aristotle.
Proud to be English 😊🏴
HS2 Hugely Silly 2
Not sure who will use it. Does not go into London, might as well catch the two existing lines that do. With UK being 2.5 trillion in debt can we afford this?
Yes we can. Next...
Only people using it are people with money. Current fares are already high..if its saving 20 mins whats the point if fares will be more expensive.
HS2 does or will go to London Euston as the tunnels are going to be bored out shortly from OOC to Euston and you ask who will use HS2, well the answer to that is every one who at present use Avanti West Coast trains on the WCML into Euston will use the HS2 route as these trains will run on the HS2 route instead of the existing WCML route
@@autodigitvlogs Every one will use the HS2 route as mentioned below saving 40 mis off the journey not 20 mins
It looks quite ugly for a vanity project
Just do this on mars, and we have a deal
Fantastic engineering achievement. Pity its in the wrong place.
Err, what like underground? Which place would be the correct place for the tunnels?
@@mrglide7078 How about between the middle and edge of Manchester, initially to link with the WCML and then HS2 if it is ever revived. That would be a far more sensible and cost effective use of 2 tunnel boring machines.
@@EASYTIGER10 Tunnelling may happen for a future line but is very expensive. Cheaper alternative would be a viaduct.
@@mrglide7078 Building a 10 mile viaduct across already built up Manchester? That just isn't viable. The demolition required and costs of land requisition/relocation would make it impractical and uneconomic. If a viaduct was viable and more cost effective they'd have planned it that way in the fist place .
But that's not my point. My point is, if you're going to the huge expense of hiring 2 tunnel boring machines, use them for something worthwhile - like vastly improving the rail infrastructure of Greater Manchester instead of under fields and trees in Buckinghamshire where cut and cover would have more than sufficed.
As a Londoner, imagine my pleasure at seeing crossrail finished - even if it was massively late and over budget. Now imagine how displeased I am to see them continue to build the fiasco known as HS2, I mean, as a Londoner I see money that could have been spent on the north /south crossrail line. Why spend so much on a line going to Birmingham! Birmingham of all places! It's madness! London is quite rightly the driving force of the country, like a glorious black hole, sucking money and resources from whatever exists north, west and east of London and it's conurbation it's a national disgrace, I tell you!! It's even using land of my country pile, I mean....
And the award for the least informative, most clichéd video on UA-cam goes to ...
any political broadcast....
All this money waisted to get faster to Birmingham??! 😊
no no you've got it the wrong way round. This is for everyone in Birmingham to move to London on mass. Incoming.......
[yawn]
Yeah whatevs
You can get to Birmingham in under 1 amd a half hours in the comfort of your own car. No one breathing over you. Itll cost you 20 quid return in an economical car with no road tax. The current lines take less than an hour. Why would i pay more to take hs2 just because it saves 15 minutes. In other European countries fares are cheaper. The brum journey shouldnt cost over £15
Look at all those people being paid to stand around and do nothing... what a waste of tax payers money
What a waste of money
No expense spared on this grandiose scheme that thought it could do as it pleased....now it's a shame maker
Million wasted on an unnecessary tunnel to keep the Chiltern nimbies happy, as a consequence of which, once more the North of England lost out.
Smacks of the Millenion tent...or I mean Dome, mess....
Waste of money, that should be used to secure our borders, build hospitals,repair schools, recruit more police, doctors, nurses, health care staff, reduce reliance on cheap labour from abroad that send their earnings back to where they came from.
Fascinating. What has that got to do with HS2?
@@mrglide7078 by the time you finish talking about HS2 and its completed. China would have been 5 steps ahead with Hyperloop and more Maglev projects completed. Air taxis live and direct. HS2 overpriced vanity project. That money should have gone to making fares cheaper so ppl are not forced to live in and around London
Whats the betting all the people who say how great it is on here, work for HS2, I've never personally met anyone that thinks it is lol
@@user-gj7ew2sm5u I don't work for HS2 but I think it's a great and much needed project in this country. Many of the antis are very short sighted. We need to build infrastructure now to secure the future transport demands of this country and it's ever expanding population as the existing infrastructure just currently isn't up to it. I do also believe it could have been done a lot cheaper by routing along existing transport corridors like they do in France but the route has been fixed so we just have to go with it.
@@autodigitvlogs "Hyperloop" says the one talking about vanity projects.
HS2 is a FUCKING waste of money 😡
Another great achievement ! Sorry, can't help feeling money would have been better spent improving existing infrastructure instead of cutting 15 minutes off a few train journeys for a privileged few. !!!
Why are you still wasting the taxpayers time and money, this line is going to be scrapped when the conservative/reform coalition get into power so cut your losses and quit while you're ahead. We don't need a third mainline to Birmingham. We need our potholes fixing instead.
First HS2 won't be scrapped and when HHS2 opens there will only be 2 main routes to London from Birmingham, the Chiltern Line and HS2
first of all, the tories are going to be decimated at the upcoming election, and it's about time. so give up on your weird fantasy of HS2 being scrapped. You know the pothole problem has come about under the tories, right? they've cut so much funding across the economy yet you still blame everyone but the tories somehow
