Meet Crossrail’s giant tunnelling machines
Can Germany’s Energy Success Happen in America? (with Osha Gray Davidson)
Electrical Safety in the Workplace – The NFPA 70E (2012) and You!
Crossrail will use eight tunnel boring machines (TBMs) to construct the new tunnels under London. These huge machines will work 24 hours a day beneath the streets of London, excavating large volumes of ground and erecting the concrete tunnel lining.
Each machine has a rotating cutter head at the front, and a series of trailers behind, housing all the mechanical and electrical equipment required for the excavation of material.
To construct the 42km of tunnel required for Crossrail the tunnel boring machines will undertake ten individual tunnel drives to construct the 6.2m diameter rail tunnels.
Each TBM weighs approximately 1000 tonnes and will be up to 140m in length with an external diameter of 7.1m. This allows for an inside tunnel diameter of 6.2m once the concrete tunnel segments are in place.
Each TBM will be operated by a ‘tunnel gang’ comprising of around twenty people – twelve people on the TBM itself and eight people working from the rear of the machine to above ground.

woa…That'ss great!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
cool
I believe in drills
very nice
If the sea rise floods the land at the entry/exits of the tunnels, all this tech and money go to waste. Much of England isn't much above sea level. I hope it doesn't happen.
Mighty impressive
Folks my app auto continued to a next playlist video. thus the weird chat response
This is what they should have done in my city, build the hwy under the city, and sell the land off above to pay for it all.
nice video to learn how to do tunneling works.
This vid was boring.

6.22 looks as if almost the entire country is a suburb of London.
Anyone A Question? If He Said End Schedule Is End Of 2014, & Now Is Near The End of 2015? Did They get It Done? & Any Other Vids Like this That Are True & Real , Le4t Me Know Please, ThanQue.

RIP Soho and St Giles 🙁
Ja som slovak :DDDDDD
WoW good cool moooooooooooooooool gooooooooool:DDDDDDDD
Huge Tunnel Machine
This is a really informative video explaining how the tunneling works and is really clear and easy to follow. As a Physicist I could watch these videos all day.
Sounds like a gender 21 to me

Those round cement blocks that goes to the roof of the tunel don't they fall?? What is causing it to stick for centuries and does not come off the roof??
Can you say "massive" reminds me of the goofers digging in my yard, but these machines could dig through a whole country.
Such complex machinery just to make tunnels. It's crazy
They need to use these TBMs to build road tunnels to alleviate congestion on the M25.
wow
im impressed, great machine
Wow this is cool. Those Germans sure do make great equipment. It boggles my mind how they are constantly on the leading edge of engineering. Good for the Brits to purchase these from Germany and use them for such a cool project. I wonder how New York would look if they had these back when they were digging their subway over 100 years ago?
Amazing!
This is the most brutal thing ever
i am very by the drilling but the work of souterain pass is too strong nerve and its application of force to sell
why does the guy raise his voice at the end
seems cheaper just to drive a car on a street
WOW! Talk about awesome technology!
So this is what causes sink holes.

يا حظنا يا حظنا ،، حنا بنصير متطورين زيّكم ،، الله اكبر ،، يعيش الملك خخخخ
A friend told me that the machines will be left in the tunnels. Is this true?
I live in montana, and when you tell people that the military has tunnel diggers they go ya, ok. DUH. Seriously! DUH? Ok, google earth=look at flathead lake in n.w. mt. Its huge, cant miss it. Now, see the tunnels, all over. Some broke off, thats why Jock Crustoe went there and did a deep dive. He made some comments on strange underwater tunnels. Thats why he went there. Others seen the TUNNELS. told him He looked for these abnomalies. See the island on the southern end of lake that looks like a fish, it does! Zoom in, lower right, tunnels broken open. Portholes for ufos. Many other abnomalies under lake aslo. UFO,/Military under water base, 4 shure! Thanks, Pastor, Chief, General, BRANCH
Remarkable, the human.
This is stone age shit! Get one of the USA DUMB nuclear boring machines. 12 Klm per hour! Melts the rock into glass for the lining – no concrete lining needed.
Amazing and powerful machine
Goooooooood
Whats the power requirement of a TBM…50-60MW?
I want to have the job of supervising the operation from the "control room". It may be monotonous, but I am infinitely fascinated with the development and technology that went into this colossus.
