HS2 Colne Valley Viaduct

[@Phil-oj5nr]

British engineering at its best. This type of structure is as bold as when the Victorians built the original railways in the UK!

[@pedromorgan99]

Engineering at best.. Its French company.. construct. .Swiss approved.. Austrian rail system.. BR was destroyed, the only british part is the navvies..

[@stevetony6876]

British designed at least…though happy to be corrected!

[@stephenfoster7257]

I hope that by the time the line is commissioned the temporary roadways & associated land alteration surrounding the bridge will be restored to previous condition.

[@stevetony6876]

I think there’s a plan for this to be done by middle of next year, though haven’t seen any photos of what it was like before..unless it’s just more of what is currently behind the fencing.

[@TrevorWilliams-fq8mg]

There night be a need for a maintenance access road which would also serve as a cure brigade access/emergency exit.

[@TrevorWilliams-fq8mg]

Should have said fire brigade access.

[@AlexanderWright1]

What are the orange pipes and containers by each pillar for?

[@stevetony6876]

Great question but I'm not sure. Might be for fluid waste drainage of some description but i really don't know....i doubt the containers are for rainwater. Thanks for watching!

[@pedromorgan99]

BTW. there are hundreds of alike structures in the Japan, Bullet Train. Shinkansen. All earth quake proof. so a different approach.

[@pedromorgan99]

perfect chord and shear thrust... ;-))) The olde engineer with abacus. would be pinch.himself.... ? Am i here ?? in a dream.. ? nai

[@stevetony6876]

Thanks Pedro. Yeah there’s a lot of engineering work in this structure I’d imagine!

[@douglasengle2704]

The Colne Valley Viaduct has a pronounced curve. What is the track design speed through the curve and what is the expected operating speed? It doesn't appear to be 320 kph 200 mph curve.

[@thorley1969]

I think it's through depth compression the curve looks so pronounced but I still think 200mph would still be possible.

[@stevetony6876]

I think I’ve read 200mph too. The drone footage gives a very curvy curve but the alignment on a map looks less pronounced… Maybe we need some speedy pendolinos to take on the challenge!

[@pedromorgan99]

Now imagine its a 3 lane motorway each side.. This is the exit ;-))

[@EdgyNumber1]

Thing is all this land will be put back to nature after construction. My inly gripe about this is that its a missed opportunity to add a cycle track alongside - either on the viaduct itself or at the ground level.

[@pedromorgan99]

@@EdgyNumber1 So been in Japan.. and played football under the viaducts on a rainy summer eve. Its was community playground. Being a welsh man, i explained rugby, and kicking it thought H viaducts... They had their own version and was fun. "In Wales, rugby is played by men with oval shaped balls" but was a communiy area..

[@pedromorgan99]

@@EdgyNumber1 Indeed, a cycle path under and walkways.. .. dare I say a Wombeling bridge.. so u can inspect the whole thing.. ;-))

[@RobboSez]

Those trees on the Down side are going to be a problem needing frequent attention, maybe even before regular services commence. They are too close.

[@stevetony6876]

You’re right they’ll definitely need cutting back at some point, regularly. Thanks for watching!

[@andrewwilliams0619]

Add some sound please

[@jacklav1]

What do you want? Elevator music? The buzzing of the drone?

[@DavidShepheard]

If you want sound maybe play this high speed rail music video in another tab: kzbin.info/www/bejne/ZmLGnoujmN2hY6s

Alternatively, there is always the InterCity theme tune you could listen to on repeat: kzbin.info/www/bejne/oGqveIx-raarh8U

[@normhanson981]

HS2 will cost not much more than test and trace , wonderful infrastructure v billions into private companies pockets , I know which one is better value. Thanks.

[@oldman1734]

Why is it running just off the ground? Why isn’t it running on the ground? Would be a lot cheaper.

[@peterjones3557]

Trains don't much like going up hills. If you can keep the incline shallow, speed can be maintained and it is more energy efficient.

[@eddaines237]

This is crossing a shallow valley to the west of London. The valley is filled with a river, a canal and lots of lakes at this point. The viaduct crosses all of these before the ground rises up to meet the tracks and a short distance after the line disappears into tunnels.

[@Pesmog]

As eddaines says the footage is deceptive but the whole area has numerous watery obstacles which is why they needed to build the UK's longest railway viaduct for 2.1 miles over the valley. It also needs to be elevated as it is lining up to enter two tunnels that are being built under the M25 which then runs for ten miles to the West. If I recall correctly the tunnel portals are slightly elevated from the the bottom of the valley so the viaduct routes into them. 👍

[@RobboSez]

Because trains don't swim too well ...

[@TrevorWilliams-fq8mg]

That's why it's called a viaduct.

[@leefairhurst9058]

And a snip at 1000 billion

[@TrevorWilliams-fq8mg]

You mean 1 billion.

[@peterjohnson1739]

Actually the current cost for this viaduct is £1.6 billion and the total for HS2 is perhaps as much as £100 billion.. that’s the whole project for one tenth of your grossly exaggerated cost.

[@leefairhurst9058]

@@TrevorWilliams-fq8mg 1 billion gets you a new toilet when it's out of the public purse .

[@davidwebb4904]

Such a shame it will never be used. Its cancellation is just weeks away.

[@stevetony6876]

Why cancelled? Maybe so who knows what tomorrow brings …maybe the line to Manchester will be reinstated, eventually. Thanks for watching. 👍

[@davidwebb4904]

@@stevetony6876 Because of corruption. Tax payers being charged 10x for the job. Friends of the Tories being gifted a blank check. This is why we cannot have nice things in this country
