Seriously, how can you put gloves on the wrong way? The grippy black section is clearly the palm! Geoff I can forgive slightly, although I think I’ve seen this in another video too, but the dude from the company?! It’s ppe dude, you should know how to where it if you are an employee! 😳🥸
@@cd66061 It perhaps should be logged as a near miss for HS2 as the effectiveness of the gloves was compromised - possible close to to point of being ineffective.
This is all very good Geoff but we never got an answer to the biggest question: why was Gareth wearing a pink hat? Do we need to follow him to find out?
I have to say Geoff and please don't take this the wrong way. That as "Boring video's" go that was one of the best I've seen in ages. An absolutely fascinating behind the scenes view of HS2. Cheers Geoff, looking forward to more!
@@ktmgordo I'm pretty sure he had them on the wrong way around in the last HS2 tunnel video he did haha. It's a recurring accidental gag at this point.
Amazing stuff. I've been following this project from afar and enjoy watching the various bits and pieces that come out on it. Isambard Brunel would have been ecstatic could he have seen this and the project overall. It's amazing technology that really hasn't changed much in 170 years. The first boring machine was used to build the Hoosac Tunnel located in western Massachusetts. The concept was successful machine wasn't powerful enough to drill into the strong granite and schist located on the eastern side of the 1-mile tunnel and got stuck in the granite and schist. It was this machine that set the cornerstone for what we have today and still use similar technology, albeit a bit more powerful and precise.
Hi Geoff. Great to see this video. The company I work for makes the tunnel segments and I was thrilled to get a glimpse of those installed in the tunnel. I am hoping to visit the LIW tunnel site soon. Thanks for sharing!
Very cool. I have seen the documentaries on the Channel Tunnel build. They had the same type of boring machines. But these are probably much more modern, since we are 30 years later. Thanks for showing us!
My first thought on watching this was claustrophobia. Then I got to the bit with the refuge and nearly freaked out. I'm most impressed by the staff 12 hours working on a shift next to the room you might have to run in to when the tunnel collapsed - that's hard core engineering. I wonder how long they'd expect folk to survive in there and under what circumstances would they get there in time.
Great video Geoff! I was wondering about whether you have another video planned or have already filmed one about the new electric buses being unveiled on route #63 in London? Would love to learn more about them as I am living on the west coast of the US and cannot ride them for myself, thanks!
Would be nice if you were allowed to have a look at the much more ambitious and bigger Chiltern Tunnel (maybe after the TBM has cleared the first ventilation shaft that they're about to reach atm at Chalfont St Peter)
2:40 the bigger question here is: why are you guys wearing the gloves on opposite hands? left glove on right hand, right glove on left hand... the rubbery grippy part doesn't go on top of your hands, mate ;) but the logo and text does
I would replace the whole London bus fleet with 13m Man Lion City DDs, 12m Solaris Urbino 12 SDs and 18m Articulated Mercedes Benz Citaros* (*If they're allowed). I might add 12m Scania N94UBs too.
I grew up in Southam just nearby and played in those woods. My family still lives there and unfortunately it's caused chaos in the area along with resentment. The cynic in me would say the tunnel is only going in so the local Polo ground isn't demolished. Other woods haven't been so lucky.
This isn't unusual, sadly. Where I live across the pond, a highway was planned to extend from Burlington Mass. to Somerville Mass. and pass directly through Arlington and Winchester. The Somerville portion of the interstate took out big swaths of neighborhoods, but the Arlington and Winchester portion was never completed. The residents were more influential and stopped the project in its tracks. Today, the interstate has dead-ended on and off ramps where this road was supposed to connect while the completed portions of Interstate 93 have razed large swaths of neighborhoods in Somerville, Charlestown and Medford. This same group of NIMBYs in Arlington also stopped the expansion of a badly needed light rail line out to an airport because they didn't want the riffraff in their town not that the people couldn't walk, driver, or take a bus and get there just the same. Today, the traffic is so bad that I dread driving through that area when I have to.
If you check the profile maps, you'll see that Long Itchington Wood is actually a significant 40m rise in the landscape. I've walked around that area, and there's no way a HS rail line is going to go over the hill, the grade is too severe.
Why build HS2 railway tunnel always short in length (e.g 1 - 21 km or called with a "kids marathon" - "half marathon" runner), thanks? Good job and good luck building that HS2 project path from London to Edinburgh.
One hopes the TBM isn't sent for scrap after boring just two miles of tunnel ! There are a couple of short tunnels on Phase 2a which will commence construction soon, (Madeley and Whitmore Heath), and also a tunnel under Crewe to be bored in Phase 2b plus the 11 mile tunnel under Manchester ! I suppose the latter will get machines of its own.
Remember that one f the Channel Tunnel TBMs is still down there - run off to the side after tunnel join and sealed up, because it was simply not worth backing out 13 miles from under the English Channel.
From what I remember, the standard linespeed of HS2 is 220mph (360km/h), and if the tunnels on HS1 (North Downs, etc) are anything to go by I think that will be the maximum speed through both this and the longer Chiltern Tunnel. Itchington is roughly 1 mile long and Chiltern 10 miles, meaning a train at 220mph should clear Itchington in about 16.3 seconds and Chiltern in 2 minutes 43 seconds. Hope this helps!
is it just me or was Geoff wearing the gloves backwards. The writing was on the palm of his hand usially iys the back of the hand and waterproff side on the palm of hand????
An interesting video about something boring, better than watching 50 navies swinging picks on a 19th Century tunnel boring scaffold. A nice refuge if the tunnel has a collape or other emergency, hope it's gas proof, whilst they wait to be rescued. The porta potty would not take long to fill!
Why have you got your gloves on the wrong way around? The rubber side goes to your palm so that you can grip things. The Maxiflex label goes in the back of your hand.
I assume they are tunnelling through Jurassic limestone and sandstone. Water I guess must be a major problem and would explain the sedate tunnelling rate compared to the Chiltrrn tunnels through chalk.
Helmet colour is used to signify the persons role or safety qualification. Blue is for ordinary persons and first aiders sometimes have a green helmet, however I am unsure why pink! Some sites, rather oddly, give pink helmets to those who have either lost or forgotten the helmet which they were initially issued with, as an act of humiliation.
Flooding of the tunnel if near a river... Undiscovered water source flooding... Tunnel collapse... Probably a lot of other things like that I would guess...
It’s unlikely to have a collapse - but you have to have a contingency. The tunnel maxes out at about 40m below the wood (not very deep) and the local geology is a fairly stable Blue Lias clay - consistently sticky… no chance of hitting chalk or shale around there.
There is a lot of high power electrical equipment together with high pressure hydraulics in that machine. Consequently there is a risk of fire, probably quite a small risk. However even a small fire underground is a serious problem.In a tunnel like this there is only one way out.. If the fire is between you and the entrance you are trapped. The fire will likely as not be producing poisonous fumes as well as using up oxygen.
Thank you Geoff for this tour around part of one of the most enormous wastes of money in British history. In typical fashion the government has already started cancelling the northern parts of HS2 so, once again, only the south of England will derive any benefit from this. If I am still alive when it is completed, i cannot imagine that I could afford to travel on it anyway as I really cannot afford the extortionate cost of rail travel now.
Just one part of the north(east); in the northwest, HS2 is still on track (sorry!). The biggest waste is having to blow £10billion digging under the Chilterns to keep the NIMBY locals quiet. But that is the cost of progress and "rights". We need the capacity on our long-distance railways once everyone realises that their new electric milk-floats will die after 200 miles of driving.

So intersting. You are most lucky to have had that wonderful opportunity. Thank you for it.
Geoff, you always have a great way of making the workers you speak with feel comfortable in sharing a little bit of their lives.

100% this.

And quite a bit wider. No doubt, however, that the 1980s Tunnel Tigers set the scene (and learned lessons) for the HS2 tunnelling teams of the 2020s.
Only in England do you find wonderful place names like Long Itchington Wood. Sounds like a good place to get a bad case of Poison Ivy !
Disappointing lack of boring/bored-related puns. I always enjoy your boring content, Geoff.
Congraduations to all the wonderful Irish personnel making this possible

Not a single double entendre about the place name and activity happening there. You're far mature than I, Geoff.
Fascinating stuff. What are the odds that this line will open before Crossrail??

As someone brought up in Southam this was my thought! It’s more Long-Itchington when pronounced.
Ahhh, I need a nice distraction today. Thanks Geoff.
Just wondering if there was a reason why everyone was wearing their gloves the wrong way round?
You've got your gloves on backwards 🤣 the black rubber coating is the palm of the glove not the back

Sorry but I can’t get over the fact that Geoff has got a right hand glove on his left hand…. Once you see it you can’t un-see it. 😅 Good video though
The wood is actually nearer Southam than Long Itchington.
So what could happen that requires a refuge chamber?
Flooding of the tunnel if near a river... Undiscovered water source flooding... Tunnel collapse...
Probably a lot of other things like that I would guess...
Engineers love the word contingency
It’s unlikely to have a collapse - but you have to have a contingency. The tunnel maxes out at about 40m below the wood (not very deep) and the local geology is a fairly stable Blue Lias clay - consistently sticky… no chance of hitting chalk or shale around there.
There is a lot of high power electrical equipment together with high pressure hydraulics in that machine. Consequently there is a risk of fire, probably quite a small risk. However even a small fire underground is a serious problem.In a tunnel like this there is only one way out.. If the fire is between you and the entrance you are trapped.
