The colossal railway tunnel, Gotthard Base Tunnel, will be opened on June, 1, 2016. Undoubtedly this huge rout with its length 57 km deserves the issue of the special exceptional coin, which reminds about this achievement. Gotthard Base Tunnel is the first in the world low-level railway in the Alps. 17 years were spent to construct it. The Swiss Mint has been already released honoring coin.

Honorable guests from Europe were invited for the official ceremony of the construction of the epoch opening.

Public fests will be held on the 4-5th of June.

Movement through the new tunnel will be possible after the 11th of December, 2016. Travel from north to south and to reverse direction is expected to be much faster than it was before. On this line passenger trains will run once per 30 min. The number of freight trains to be used on this line is 260 (only 180 trains were before).
