Drilling world's longest rail tunnel

The world's longest railroad tunnel moved a step closer to completion as Swiss drilling crews sliced across the final 6 feet of rock in a ceremony broadcast live on nationwide television.

Tunnel-drilling machine "Sissi" reached the final breakthrough on the Faido side, in the Italian-speaking canton of Ticino, around 8:17 a.m. EDT Friday.

Drilling and blasting on the 35-mile tunnel linking Erstfeld in German-speaking central Switzerland and Bodio in the Italian-speaking south began in 1996. The tunnel is scheduled for completion in 2017 at an estimated cost of $19.7 billion. It will be the world's longest underground rail link, beating the 33.5-mile SeikanTunnel in Japan.

Trains will be able to speed through the tunnel at 155 miles per hour, shortening the four-hour train journey between Zurich and Milan by 25 percent.

This is an outstanding New Yorker feature on this project, specifically the tunneling machines used to complete it, published a couple years ago.

what a mistake it was to not tunnel thru Tyson's. The politico's responsible for that decision, will be looked back upon with disdain.

it is good that they didn't put a tunnel through Tysons, now everyone will be able to see the Metro delays instead of hiding them underground
