SBB platform and track system renewal at Arth-Goldau railway station
mid 2015–mid 2018
The SBB is expanding access routes to the Gotthard, and thus also between Zug and Arth-Goldau. A 1.7-kilometre-long dual track is being built near Walchwil. At the same time, the SBB is renovating tunnels, bridges, railway technology and tracks along the route, and renewing the platform and track systems in the Arth-Goldau railway station.
Platforms are being raised, making it easier to board and alight. Punctuality is being increased thanks to higher-speed switches. Platform roofs are being altered for the planned four-metre corridor. At the same time, modifications are being made to platform roofs and lighting is being renewed. This project can only be realised by closing the east side of Lake Zug between Zug Oberwil and Arth-Goldau.
A number of trains will run at different times or will be cancelled. Furthermore, various hindrances and changes in terms of access to trains can be expected throughout the construction period.
