If it goes down too much, the stations have to be made deep and the cost is rising. In general, the line goes linear, if there is no problem in the infrastructure.

Will you use a special technique on your fourth metro?
“We use the latest technology in all the subways we make. We use the TBM machine, which we call 'mole'. The device is like a computer center. There is a head that performs drilling at the front and the back is like a factory. Sometimes it goes up to 100 meters. As he advances, he pulls back. It takes the concrete segment parts that were previously prepared and that will form the walls of the tunnel, and as it progresses, it also forms the tunnel by placing them in rings, that is, circular. It then fills the gaps between this wall and the excavated ground by injection. When the machine is finished, the tunnel is physically finished. In the systems we call electromechanical, ventilation, signalization, rails and other equipment are placed later and tests are made with the arrival of wagons. We currently have 7 TBM machines that we use in various projects. ”
