The Gotthard Base Tunnel comprises two 57-kilometer single-track tubes. They are interconnected every 325 meters with cross passages. Including all of the connecting and access tunnels and shafts, the entire tunnel system is more than 150 kilometers in length.
The gripper tunnel boring machine (TBM) braces the gripper plates <1> laterally against the tunnel wall enabling the thrust cylinders <2> to push the rotating cutterhead <3> forward.
The TBM operator drives the machine from the control cabin <4> and monitors tunnelling.
A belt conveyor <5> integrated in the TBM transports the excavated material toward the rear.
