The world’s longest railroad tunnel moved a step closer to completion as Swiss drilling crews sliced across the final 1.8 meters (6 feet) of rock in a ceremony broadcast live on nationwide television.
Tunnel-drilling machine “Sissi” reached the final breakthrough on the Faido side, in the Italian-speaking canton of Ticino, around 2:17 p.m. today in the presence of Transport Minister Moritz Leuenberger.
