World’s Longest Railroad Tunnel Set to Open in Switzerland Next Year
The Gotthard Base Tunnel in the Swiss Alps is poised to be the world’s longest railroad tunnel. At 57 kilometers (35 miles) long, the tunnel will open in December of 2016 and transport more than 200 trains a day, each at an average speed of 250 kilometers per hour (that’s 155 mph).
The tunnel was conceptualized to alleviate the burden of freight traffic on Switzerland’s alpine ecosystem. . . .
