The date is getting closer. December 2016 will see the opening of the Gotthard Base Tunnel in Switzerland – at 57 kilometers the longest train tunnel in the world. At a depth inside the Gotthard massif of more than 2000 meters, trains will travel at up to a maximum of 250 kilometers per hour. And as an attractive alternative, travelers can make the return trip by the historic panorama route over the Gotthard.
