the amount of concrete!!!!!

:....

just so people can bitch about how its smelly and hot in the train and how slow it is lol

The amount of mother earth that is destroyed in all such projects is insane

thanks for providing the additional context

too bad you didn't get the prefab bags of leaves

Yeah, I feel wrecked after painting windows and doors with a small brush.

That is how all shotcrete walls are built

Well of course Norway does it best lol. You can't drive 200m in Norway without needing a bridge or a tunnel or a ferry.

Most likely France by the looks of it.

In democracies sometimes it is cheaper to go underground with a number of modern multi modal TBM working 24/7 than have expensive court cases. A single 11 psi Maglev tunnel can increase speed from 600 km/h to 700km/h while still being breathable and passing stations would allow daytime trains to stop where needed with overnight container trains beating any truck by eight hours over 1,000 kilometres between freight sidings eliminating daytime planes and reducing trucks. Using Sydney to Melbourne as an example with passing stations at Canberra and Albury it would cost $60,000,000,000 and return $20,000,000 per night which makes it able to subsidise daytime fares below planes and still have a return of 10% Perhaps cooperation between Japan, China and America can develop the maglev container train with Australia to use an international guideway to benefit the world.

@Abdo Abdo - The workers are definitely not Chinese. Based on the people and cold snowy weather it’s South Africa.

@Abdo Abdo Doesn't change the fact that this came from France or a French speaking country. China isn't the only country in the world that could do things very quickly.

China

France

France

Not the United States. Our government gives our money away to others that hate us and wish us dead, that's why we can't have nice things.

Ага это не Россия 🤦🏻‍♂️ нам ещё 100 лет до них идти если дойдём!

@@user-hk9wx1ee2n На кой нам до них идти? Если очень хочется иди сам до них. А за других решать не надо.

@@HentaizerZ дружище ты в корне не прав! Я не в том плане,что кого-то хочу оскорбить или обидеть,а в том что хотелось бы чтоб у нас было лучше! Я очень люблю,свою родину!

Лол у нас тоже так строят ,просто не пойму почему шебни можно же бедон сделать

🤣

This clip refer from the NYC?

Luck and vast numbers? 🤔

i didnt know we had underground trains thousands of years ago. well everyday u learn something i guess

Stringlines and candles, then a car spot lamp shining through steel plate target onto a predictor screen, letter across the top and numbers down the side gave us the coordinates to aim the TBM at for the shift. Then came the laser in the 1970s

That's ok there's a whole bunch of Townhouses near me that have been built since.... 2018? And they're still "under construction."

Только у нас в стране понятно что ничего в итоге и не сделается.

@@milhousevanhouten5191 Ты с западной европы?

my experience, only excavation speed not including lining speed was 6～10m/day but it depends on hardness of ground

Your govt is a western puppet

This method of construction is Known as Top down constructions using diaphragm walls and Pile columns.. almost all Indian City metro underground stations of Delhi metro, Bangalore metro are constructed using same method that too 10 to 20 years back.. probably you are not aware of this

LOL!

Also it would make wars a 1000x more difficult to fight. Those with the tech would become very secure. Like Switzerland.

The main reason we need it is because the legacy infrastructure that we have was not designed for high speeds. less traffic would be an added benefit. I think it would be brilliant to leapfrog bullet trains with this idea. Which imo is much better.

А чего экологи? Кто сказал, что жители не возмущаются, вполне возможно, что и возмущались, но это же метро строят, а не ТЦ. Пробок меньше, цена на недвижимость в районе растёт.

I'm not sure, not an expert or an engineer. But I think I read somewhere that the temperature under the frost line is stable throughout the year.

High speed rail is welded everywhere in the world I think. Sleepers can actually hold rails in place despite thermal expansion if done right. Even Estonian slow rails are welded and we have awful thermal cycles at times. Otherwise trains would make clunking sound when they travel. Modern tracks are more quet.

Googled a bit. It turns out that for long sections without gaps, rails are placed at a strictly defined temperature and the rail is stretched before installation. On slow sections, the usual gap. (if anything, yandex translator)

That is not rubber, that is steel only.. steel members will bend if length of the member is so long

Да верно
