Travel by underground train has become very common worldwide. For this purpose long train lines are established and beautiful stations are also constructed. But do you know how to dig the ground for this tonnage transport system and how to prepare a tunnel for underground trains?
A machine called Earth Pressure Balance Sheet is used to dig underground tunnels. At the front of it, a powerful machine is installed that rotates. The entire machine is 40 feet in diameter and 312 feet in length. The machine can dig up to 1,000 feet every week underground.

They are really already working (building) miracles today
Technology is at huge boom
When I was in London in 1986, they were using the MOLE which is like a giant and very long drill.
Yeah , but this is great technology.
If I’m not mistaken, they used this machine when drilling a tunnel by sea between Great Britain and France
