There are now plans to turn it into a museum and part of the train line into a ride. Read More

Gizmag goes inside the world's largest tunnel boring machine

On Saturday, a tunnel boring machine (TBM) so large that it looks like something out of Thunderbirds was dedicated in the city of Seattle. “Bertha,” as it’s known, is the world’s largest TBM and will spend the next 14 months boring a 1.7 mile (2.7 km) tunnel under the city as part of a US$3.1 billion project to replace a viaduct damaged in a 2001 earthquake. As part of a press tour, the Washington State Department of Transportation (WSDOT) allowed Gizmag inside the giant machine. Read More
