How Deep Are We Underground?

Sometimes, you enter a rather nondescript looking station like the one in the photo to board a train. Instead of going down just a flight of stairs, you saw a seemingly endless downward tunnel.

You keep on going down by the stairs or the escalators and after a while, you start to wonder how deep are you exactly underground.

And you start to marvel how they managed to dig so deep underground for the station and track and yet life goes on above ground.

We are not even halfway up yet! Won't be seeing the sunlight yet until you take a few more escalators up. o.O

Going up, uP and UP! And keep to left when you are on one. ^^

Thinking about these maze in the belly of Tokyo somehow reminded me of my own hometown in Raub, Pahang. In its heyday of mining in the early of 20th century; Raub was the "Malayan Capital of Gold". Using shaft mining and operated by the Royal Australian Gold Mine; these tunnel snaked through under the town. No building in the town centre of Raub can be more than 4-storey high because of these tunnel. The tunnels were blasted closed by the British during the Japanese Occupation in the WWII.

A controversial  mining is set to work full force in Raub using the "carbon in leach" method using sodium cyanide to get gold from old mines that used traditional mining methods previously.
