[@RichardFraser-y9t]

The HS2 Ltd channel posted a new video about the tunnels and shafts today, well worth watching.

[@katrinabryce]

I came here from watching a video on HS2's own channel about the ventillation shafts.

[@Lxmix336]

It must be a true pleasure to work for the construction of HS2 and its nice to see how it works. Thanks Geoff for the informative and interesting video!

Geoff saying 'Mind the gap!' as the man cage door is opened. New recording for train door operation at those stations where it's required?

[@DerickRethansXdebug]

I live next door to one of those, and they offered to have a view inside it at a community engagement event. It ran over due to people complaining about subsidence (impossible, as they hadn't started digging yet) and then cancelled the really fun part of it: the tunnel visit :-/

[@WhiteTiger333]

Wow - cool! I would have thought the tunnel boring machines would leave the same way they arrived. Ah, well, I'm sure there is some sound reason why not.

[@johnm2012]

Do you mean you expect them to go backwards through the tunnels they've just bored? They can't because they line the tunnel as they cut it so the tunnel diameter is smaller than the cutting face. There will be four machines arriving in that shaft from two directions so there's nowhere for them to go except up the shaft after being dismantled.

[@WhiteTiger333]

@@johnm2012 Ah, okay - thank you. Now I have the perspective!

[@markomarten]

I liked the “ mind the gap” bit, that was a good one as it were Geoff, maybe you could discretely add them in every so often. I wonder how big the Tunnel Boring Machines are, I don’t know if they can tell you or maybe nobody knows. Say what you want but it’s boring stuff made exciting!

[@andrewreynolds4949]

From the HS2 website, the TBMs are about 170m long, weigh ~2000 tons and have a cutting head diameter of around 10m across

[@TrevorWilliams-fq8mg]

That's the entire machine. The cutting head is about 15 metres long.

[@andrewreynolds4949]

[@willlister9825]

Excellent footage as always! I've never fully understood why this tunnel is being built from both ends rather than throughout like the other ones though...

[@Jaydotp]

I understand why HS2 does this. If I had my entire top half chopped off, I'd need a massive vent too

[@emmant1759]

[@Saint_Dan132]

[@JP_TaVeryMuch]

4:34 They're called Reinforcing rods in this country. And "the swinging lift thing ... the only reason [you] came" is somehow sniggeringly called (I checked) a Manrider. Choose your words advisedly!

[@TheShuttleLine]

yes thats nice

[@Ambo100]

0:18 are these marking the names of vent shafts or stations? I've never heard of a Canterbury station in London.

[@Ogrecrusher]

It's names of nearby roads. Canterbury Road is the location of that one

[@andrewreynolds4949]

Vent shafts. There will not be that many stations on HS2

[@Ztbmrc1]

How impressive! Was that word "base-heave" ? So the possible lifting up of the base of the shaft by the water pressure I guess?

[@fcbarcelona-clashroyale4778]

Is it for vent? Because I once saw a similar kind of big hole during a report about the Grand Paris Express (Paris Métro huge extension project), and the hole was used to assemble a tunnel boring machine to then dig the tunnels.

[@southcalder]

Good to see all the work on the Birmingham Branch line. Unless the northern section is put back on track, or some serious improvements are made to the WCML north of Crewe (because HS2 trains will be limited to 110mph over much of the line) it will have been a complete waste. What we’ve managed to do is bypass one of the least congested sections of the WCML (with Crewe northwards being the bit that struggles the most fitting the mixed traffic in).

[@DoubleD20s]

But did you go down 15 storeys?

[@raphaelnikolaus0486]

@ 3:46 Base heap did he say??? I've never heard of that word before either!!! 🤔🚂🚂🚂

Base heave, where the ground (and particularly the ground water) wants to shove the shaft up out of the ground, a bit like a plastic bottle held underwater

[@MrJimheeren]

With all these tunnels I start to get why HS2 is so goddamn expensive. The TGV just slowly rides out of Paris and as soon as you leave the city the speed goes to 11. This is quite a lot of work for only a couple of minutes faster arriving times

[@charlesgund4812]

My girlfriend was surprised at the size of the shaft

[@edwardwilcox6606]

Geoff is there any merit in thinking that HS2 should have started in Leeds rather than London? The powers that be talked of the importance of `levelling-up` with the North with this rail project but as has transpired this will not be the case. All the money spent in the South ( London to B`ham ) could have been better spent on improving connectivity between Leeds & Manchester ( & other cities perhaps ) down to B`ham with to prospect of building a not so grand line so as to actually be able to complete the project. I`m not a `Northerner` but even I feel cheated that these grand projects will be complete in the South at the expence of building much needed basic infrastructure that the North craves & was promised. I feel we`ve missed a great opportunity to link our cities the way the Europeans have done to the detriment of the nation as a hole. Perhaps my thoughts are way off the mark?!

The traffic jams this causes in Greenford are an absolute joke and it's been going on for over a year now, I've stopped going to the Westway Cross Retail Park because of this, in fact HS2 causes a lot of traffic problems in West London , ask people who use the A40 at Hanger Lane, it's a nightmare.

[@TrainLifeGB]

Hey Geoff do you plan on checking the new class 458/4s out?

[@davidflack6430]

I think HS2 is one of those projects that has been overtaken by peoples ways of working. I no longer need to have fast transport to Birmingham, I just use MS teams to attend a meeting. When I did travel to Birmingham the slow bit was getting from my house to Euston.

[@mike7002]

I am not in agreement to build HS2. That said the engineering skills learned are of benefit to those engineers.

[@j3xk72r9]

I don't think many people realise how much of HS2 is underground and how unpleasant it will be for passengers. I think many people will try it once and go back to the above ground alternative.

[@rockerjim8045]

you can blame the tories for that. they forced the tunnels so as not to upset the voters in their constituencies

[@andrewreynolds4949]

Not sure how that’s such a bad thing… the Underground and many other systems are, of course, underground. It’s really not much different from being on a plane most of the time, as far as view goes.

[@-Osiris-]

This comment is unhinged. I care about getting to my destination quickly and safely, whether that's above or below ground I don't care, no one cares! "Unpleasant for passengers"? What are you talking about??
