In addition to its famous banks and exquisite chocolate, Switzerland is also famous for its excellent transport system, which works "like a Swiss watch". The Alpine region covers two thirds of Switzerland's surface. To date, around 1,300 tunnels with various functions have been built in the Swiss mountains, including the world's longest Gotthard Railway Tunnel. #ToInteresting Anyone who wants to support our channel can become a sponsor! / @tointeresujace7074
