360 tonnes, 4 kilometers, just a few millimeters of space - a thrill-
seekers ride in reverse, complete with tunnel vision. Hop on board while
our Herrenknecht team takes on the logistics challenge of the year in
the Gotthard Pass: driving the heaviest part of the tunnel-boring
machine four kilometers backwards on a heavy-duty transporter. This is
not for the faint of heart, but a pure adventure for the entire team.
