World's deepest rail tunnel opens in Switzerland

World's longest, deepest rail tunnel opens in Switzerland: "High-speed trains take just 17 minutes to roll through the 35-mile-long tunnel under the Swiss Alps.

The trip took days until the first alpine rail tunnel opened in 1882.

The old rail route went over a pass in a series of loops and tunnels.

This new, flat route has been under construction for 17 years, and cost about $23 billion.

The first people to travel through the tunnel included 500 lucky winners of a ticket lottery.

Around 260 freight trains and 65 passenger trains will traverse the tunnel daily."
