I've hardly imagined what big stuffs are supporting the construction of the station

Sendai Station, where I get off every day to go to work, is under construction.

A new subway line will be open for the next year, and commercial complex is also planned.
The passage from the east to the west of the station will be expanded and I hear that new gate will be open when new passage is open.

Every morning, when I arrive at the station, I see the construction site of the east of the station.

Today, I saw a huge crane.
It had a label saying its maximum load is 300 tons.
300 tons, not 300 kilograms.

I have thought that 300 kilograms is heavy enough.
At least I can't lift this much.

At fast I could hardly imagine how heavy 300 tons is.
Later I imagined that the crane can lift about 200 taxis (about 1.5 tons for each one) at the same time, then I imagined that it can also lift the whole train I had just rode. It was 6-cars and about 40 tons for each car.

I haven't imagined what big machines support the construction, which require columns, pillars, frames, floors to support tens of thousands of people at a time.
