How Are Subways Built Underground?

Have you ever wondered how subways are built underground? We explain the complex process.

I don't know why I randomly had a thought that wanted to know about this but it's interesting

[baab]

I have lived until my adulthood without knowing that people have built such a complex machine just to make subways.

reminds me of that drill used to destroy the wall of basingsey in the avatar last airbender

Damn I never knew how they made them! Thanks insider

We will be having it soon here in Metro Manila Philippines, its under construction now. Just got curious how they dig and make tunnels.

Do they do spot tests first to see if they're digging through pipes or underground wiring? What if they dig into an open underground cave?

[d.g.]

And after it's done, how do they put the trains underground? Do they use electricity or some kind of a fuel? How fast does it go exactlу? How do people get qualified to drive a subway? Are there ones just for practice??? I have so many questions

[kingtryton]

this is definitely way more modern then how it was done in the 20th century also wonder if they ever find anything digging that deep like old skeletal remains, treasures etc

[ssbib]

That’s ace but how does it handle corners?

[Caleb]

Ahhh its so addicting watching these Insider videos... Idk why :/

[adg]

I hope we could have this in our city someday. ^_^

its a transport and also can be use as a bomb shelter

[trevorwilliams]

So much for the tunnel boring where the trains run, but what about the underground platform concourse and interconnecting passageways ?

[thenewbiegamer]

it reminds me of azula's drill on ba sing se

[aceyma]

[astyx]

What does it do with the leftover dirt?

Bangladesh is starting MRT1 project after sucessful MRT6. In this project, underground is the way to go. Interesting machines.
