Gotthard Base Tunnel

Trains can change tunnels in the two multifunction stations (MFS) at Sedrun and Faido. These stations will house ventilation equipment and technical infrastructure and will serve as emergency stops and evacuation routes upon tunnel completion.
Access to the site where the Sedrun station is being excavated is by a level access tunnel 1 km (0.6 mi) from the valley floor near Sedrun, at the end which two shafts lead 800 m (2,625 ft) straight down to the base tunnel level. A project to construct a functioning railway station called Porta Alpina at this site was put on indefinite hold in September 2007.
In May 2009, final break-through for all tunnels was projected for Spring 2011. In December 2009, the expected date the final break-through for the east tube was moved back to November 2010.
