Chengdu is busy building its new Metro subway line. This involves tunneling under the city with large machines. The plan is to create two lines; one running North-South and the other East-West. The entire system will take a few years to complete, but I was lucky enough to take a tour and get up close and personal with the mighty machine.
We first explored the site on ground level taking notice of the large amounts of earth laden containers used to move what was recently dug up. Then it was underground with a hard hat and site supervisor. We toured the first length of the tunnel which already had its concrete ring. Then we made our way into the machine from the rear and right up to the very front, just behind the cutting wheel. Too cool!
