How HS2 are connecting two major super structures below ground

[@1chish]

An excellent introduction to this section. Thank you. When people wonder why HS2 costs what it does tunnels are the reason and in a crowded country like the UK they are very necessary.

[@fndjfgsdk]

They’re really not necessary at the scale they’ve been built though. We didn’t need to go under the chilterns at all but then the NIMBYs were given rights…

[@1chish]

@@fndjfgsdk One person's NIMBY is another person loving their neighbourhood. The extra cost spread over the 100 years this line will operate is a round of drinks.

Yeah, such a "great project". The Golborne link - scrapped. The Eastern leg - scrapped. The Northern leg - scrapped. The disaster that is Euston station - "on hold" for two years & will only continue if private investment can be found. HS2 is an environmental disaster of epic proportions & Britain's biggest infrastructure mistake in half a century

[@JP_TaVeryMuch]

@@CRIMSONANT1 I tell you what _is_ great; quite by chance and a first class example of the lore of unintended consequences, this whole enormous infrastructure undertaking, being just about the first one in the country of this new millennium, it's been unable to avoid the obstruction fast approaching up the track that is the sap-sponge of social media. Therefore, perhaps with the help of all those reed bed filter ponds, it's inadvertently donned the mantle of the national soaker-upper of much of the moaning Minnies' most acidic accusations, biggest baseless barbs and is the repository of the largest number of inexpert analysis of anything in time ever in this country or any other. And if you concur with that last point of fact, then you are due my grateful thanks for personally proving the point.

Hi . thanks for the update. Have built a 1to 100 scale model of Acton Wells junction including your tunnel under the junction. Will put in the main tunnels when you have built them. Also have built part of you elevators too. Caroline

[@marjorieinglis4648]

If I have understood correctly, (which is not necessarily the case), the 360m long Spray Concrete Lined (SCL) tunnels between Victoria Road Crossover Box and Old Oak Common, starting firstly with the pilot hole(s) are not created with TBMs, what machinery is it that is used to excavate them?. Are these "short" tunnels aggregated in (or not) somewhere with the rest of the tunnel lengths shown on the HS2 website?

As a hard working engineer, that understands the typography your cutting though, I'm surprised you haven't had major flooding and that your keeping costs down, while keeping green.

[@commonsense3482]

Unfortunately HS2 LTD were their worst enemy with the initial marketing talking about time saving and not also focusing on the release of capacity on the existing lines and platforms which will be able to handle more local / regional stopping services plus freight. Could there have been improvements to HS2 phase 1 - Yes, but I do also support the need to get on and build the next stages of HS2 phases 2a and 2b to better connect with more reliable alternatives our great cities.

A gross waste of public money when we don't have enough hospitals, prisons and can't drive down a road without hitting potholes. NOW if they built a motorway purely for heavy goods vehicles then that would make much more sense and releave the overburdened motorways

Why is there a £22 billion black hole and now hard working families have gotta pay for it after we've already been suffering exponential rises in mortgage rates, council tax and VAT at 20% since 2011? 🤔

[@TrevorWilliams-fq8mg]

The answer to your first question is there wouldn't have been if the Tories would have won the election because their manifesto was costed. But because Labour have a different manifesto the goal posts are in a different position . So both parties are right for their own manifestos. The answer to your second question is because the working classes form the biggest population class, and therefore have the biggest fund of money for taxing when taking the super rich out of the equation, who will now take most of their riches out of the Country.

[@peterjohnson1739]

Current mortgage rates are low … in the 1970s they were typically 7.5% and briefly rose to over 15%.

[@SoloSi2024]

​@@peterjohnson1739As a percentage of what though? In 1976, our family home cost 15k.

[@peterjohnson1739]

@@SoloSi2024 There has been a large amount of inflation since 1975; most of it by 2000. This has pushed both wages and house prices up. Mortgage rates are LOWER today than in 1975 is a TRUE statement. Which you can easily verify. “Exponential rises in mortgage rates” is a FALSE statement. Mathematically recent mortgage rates have risen very slowly not “exponentially” (which needs every rise to be proportionally higher than the previous rise). My point … before sounding off get your facts and mathematics right!

Billions of pounds to save 20 mins...... interesting!

[@lukesdad5218]

It's primarily a rail capacity boost that'd cost multiple times the price of HS2 if they tried to upgrade the existing WCML from the West Midlands. £14 Bn (£28Bn at 2024 prices) was spent on the Trent Valley section in the early 2000's and achieved about 10% of the expected benefits. It'd require the whole of the HS2 budget to fully complete just that 55 mile section! The amount of disruption would be horrendous and last for a decade or more. And, FYI, the current time to Euston is 85 minutes and that'll reduce to 49 min, once the full route is complete. A trip from Central Birmingham to Heathrow (change at Old Oak Common) will take an hour, compared to the current 2hr 30min.

[@CRIMSONANT1]

​@@lukesdad5218.. arguments that the WCML is "full to capacity" rely on a discredited, out of date forecasting model which overestimates long distance passenger growth & isn't used for anything anymore except to justify the monstrous vanity project that is HS2. Network Rail's "New Lines Programme Capacity Analysis" shows that WCML capacity is kept artificially low by private operators wanting to maximise profits. A DfT analysis shows that in peak hours leaving Euston, WCML trains were loaded at just 52.2%.

[@8492946able]

HS2 was originally designed for capacity (to take people off the WCML as it is nearing capacity), by removing the people from WCML it would allow for more freight/stopping trains to operate. Now because of Tories the original plan will take longer and cost more

[@MrMWRMWR]

Pay attention please.😢

[@MrMWRMWR]

I'm not understanding the spray concrete lining strategy. Are they only needed because larger and more complex cross section tunnel sections are needed? Are these the final operational shape of the tunnels at this location? Are strength probes only inserted at convenient locations or all around? Scary as it will only be as strong as the weakest point. Nevertheless, some fantastic insights in this video👏🏻
