HS2 completes first Chiltern Tunnel cross passages
Вставка
- Опубліковано 21 сер 2022
- The construction of HS2’s longest tunnels stretching for 10 miles under the Chilterns has begun a new phase with the start of work on thirty-eight cross passages linking the north and southbound tunnels.
The Chiltern tunnels will carry high speed trains between London and the North at speeds of up to 200mph (320km/h). The trains will travel through two parallel tunnels linked by short passages for use in emergencies.

Fantastic to see the wonderful project taking shape. I'll look forward to the day I travel on HS2.
Liz truss is against hs2, it will be scrapped if she becomes pm!!
@@swinger9374 She might have scrapped it is construction hasn't already started but she's certainly not going to scrap it now!
Aged well…@@HenrysAdventures
So much going on that is crucial to the project and rarely seen.
Would love a slow time lapse from the portal to the front of Florence, be interesting to see the progress of the invert slab, cross passages and through Chalfont St Peter’s vent shaft
You all team have done great job
Really looks great waterproofing works
It's amazing how people can grow like this. You can make a general contractor and advance into overseas business.
Very informative and exciting.
Time to update the longitudinal section cutaway illustration to show doors along the tunnel walls now you have two bores being connected every 500m.
News today from Eurotunnel was just how useful those cross-passages (to their service tunnel), and robust operating procedures to evacuate failed trains before complaints go viral, are!
does the waterproofing go onto the chalk or is there a shotcrete layer applied beforehand?
Imagine the kudos you will have on your cv if you have been involved in the building of hs2. Nice to see a female engineer involved,l bet her parents are so proud of her.
Indeed. Heavy lifting will be done by the men of course tho
@@miketw3068 As always my friend.
Imagine valuing your life based on a CV lol
@@AB-hu2uw Unfotunately some people do.
@@colinsmith1288 very sad, there more to life
Oh yeah the emergency tunnels.
forgot those are a required thing hehe.

I don’t know what is going to happen to lorry drivers when this project is finished.
When HS2 is finished, it will free up capacity on existing mainlines and more freight trains will run.
That modal shift will free up space on motorways and A-roads and lead to a better driving experience for the lorry drivers who continue to deliver goods by road.
The last mile to shops will still need sorting out, so it's possible we will see a switch from long distance lorry drivers to short distance lorry drivers.

Uhhhhhh I uhhhhhh was wondering when uhhhh ?
Suceess depends on the actions or steps you take to
achieve it. Show me a man with no investment and I'll tell
you how long it takes to fail. The investment creates a
safe haven for the future. With the right investment
choi noce that has at least a minimum risk of 2% and with
expert advice, both profits and interest are 100%
guaranteed.
why put ads on these videos? short on cash?
Ads are on everything on UA-cam
Need to make up some of that £100bn somehow 😂

@@Alto53 thats so unfair, Hs2 to will be paying for it self in 250 years if it is still open.
Anyone reading.... You owe it yourself to do all the
things you've dreamed. take that risk step to become
financial stable in this economy situation, I strongly
recommend Mr Johnson his trading strategies
and analysis are second to none, thanks for your help
on my family sir much love.
Please get rid of the fscking music in all your videos, it makes them un-listenable to. I'd like to hear the presenters and interviewed people but have to have the sound off. Shame.
Noise is part of construction so please be patience
Why should we be enthusiastic about progress with Cameron's Folly. Complete waste of money that could be better spent on improving the existing rail netwok.
Oh come on we all love seeing , empty rail rolling stock and buses with no one on them. Plus the London folk screw every thing up for the rest of the country they need to get away from the north fast. The belief that HS2 is needed is that you have bought in to the lie, Or a rail worker.
This is "improving the existiing rail network".
At the moment our mainlines are blighted by mixed traffic. Because fast trains catch up slow trains, the people who design timetables have to leave massive gaps in front of express trains, so that they don't catch up the stopping services in front of them.
And that's the reason that train frequencies outside of South East England are so terrible.
When HS2 opens, the InterCity trains that travel via Birmingham will switch over to this new line and the mixed traffic problem will go away.
And that will allow them to run more trains on those lines.
So many job opportunitys with HS2, But as a white englishman, im disgusted with the amount of box ticking of employing foreign workers...
I feel discriminated as a white english man here !!! i have 1st hand experience of workers who hardly speak any dam english
boo hoo
Sorry, but this is a total waste of public money.
No its not! Its the great investment our railways need!
@Henrys Adventures .. an environmental disaster of epic proportions and the biggest White Elephant this country has ever seen.
As recently as last May, the Public Accounts Committee stated that HS2 would NEVER offer value for money and in a post Brexit, post Covid society, the proposed passenger numbers could NEVER be achieved.
Excellent news that the Eastern leg and the Golborne link have now been cancelled and fingers crossed the rest of this monstrous vanity project will never see the light of day.
I'd say the 37 billion wasted on a track and trace system that didn't even work is bigger.
@@davidty2006 .. HS2 is now expected to cost upwards of £200 billion when the whole sorry project is completed in approx 2040 & will have destroyed vast swathes of the English countryside .. track & trace was a "bargain" compared to this monstrosity.
@@CRIMSONANT1 Motorways have destroyed more of the countryside than small railway, Cancelled HS2 and that taxes payers money will go into more roads, HS2 will be a game changer, All the High Speed trains will transfer to the new line and the WCML Line will free up more space for more commuter trains and will take lorries off the road and onto frieght trains.
Privatised rail travel is dying. This is an insane waste of time and resources.
Hang on.
HS 2 is government owned last i checked.
Not private.
It’s the future .
These tunnels need converting to water reservoirs ASAP. They can hold a couple of billion litres of water.
We need water urgently not a third line to Birmingham.
I've just had a long hot bath after watering my garden with the hosepipe!
I left the hose on for 24hrs and the realised but decided to leave it on
@@heidirabenau511
You will not be doing that much longer if wee do not convert these tunnels to reservoirs.
maybe start digging up the M6 to fix the pipes first...
@@davidty2006
The HS2 32.8km long Chiltern tunnels can be used as a reservoir for a few billion litres of urgently needed water. It could be operational in a few years. A quick and *URGENTLY NEEDED* reservoir.
HS2 from London can run onto an upgraded Chiltern Line at Colne Valley. Chiltern Railways say that an electrified Chiltern Line will be 7 minutes slower than the proposed HS2. Using the HS2 tunnel to the Colne Valley and then onto an upgraded Chiltern Line, eliminating the ugly viaduct, will at least equal HS2 journey time to Birmingham. The Chiltern Line is a more direct and shorter route to Birmingham than HS2.
Oh how exciting it would make a good land fill before being closed forever. Expensive but when you just have to spend tax payers money on something, suppose it might as well be this.
It's too expensive to close tbh...
And ironic part is laying the track it's self is the cheapest bit.
Due to the high capacity the woodhead tunnel number 3 was built in 1953 to aid the other 2 tunnels that had run 100 years , on building it they closed the old tunnels, in 18 years later tunnel 3 was closed to passengers due to low demand. is this what will happen with hs2.
@@RichieWellock doubt since they'll just send all of avanti's trains down it.
@@davidty2006 That the whole idea of HS2, The Avanti trains will transfer from the WCML line at London Euston onto the new line to Birmingham Curzon Street Station and there will be more space for regional and local commuter trains plus frieght.
Its designed to increase future capacity for many many decades into the future. Its well known that government-funded projects stimulate the economy, in fact my employer has had work from this project so I have seen it myself.
