SBB completes double track at Walchwil on Lake Zug

SBB built a new 1.7 km double-track section on the Zug–Arth-Goldau line along the eastern shore of Lake Zug near Walchwil and renewed about 15 km of track including tunnels, bridges and retaining walls. The project cost roughly CHF 190-200 million, with construction under full closure of the line running from June 2019 to December 2020. The goal was denser train service (half-hourly S-Bahn, more long-distance trains) on the north-south Gotthard axis.
