Tunnel

Isambard Kingdom Brunel is one of Britain's greatest-ever engineers. His first project was the Rotherhithe Shaft, the starting point for London's Thames Tunnel. The tunnel was the first in the world known to be built underneath a river and the shaft is now set to become a theater.

Drones flown by Amazon aren't the only way we could be getting our parcels delivered in the near future. UK firm Mole Solutions is exploring the possibility of using small robot trains running on underground tracks to manage deliveries, and it's just received funding from the British government to help test the viability of the proposal.

Creating a new 118-km (73-mile) rail route with 10 new stations and 42 km (26 miles) of new tunnels is no mean feat. The logistics of doing so in one of the world’s major cities, however, are staggering. That is the task for the UK's Crossrail line. Major tunneling ends in May, so Gizmag went to take a look.

It's now over a century (101 years, to be exact) since ground was first struck to build the London Post Office Railway, an underground tunnel system that transported the bulk of the city’s letters and parcels between sorting and delivery stations. When it opened in 1927 it was the world's first driverless, electrified railway, and operated up until 2003, when it closed due to financial reasons. There are now plans to turn it into a museum and part of the train line into a ride. Read More
For anyone who worries about being caught in a cave-in, you'll be glad to know that tunnels such as those found in subways or mountain roads are regularly checked for structural degradation. These tests are typically performed using the naked human eye, and require the tunnel to be closed to use for as long as the process takes. With this in mind, the European Union ROBINSPECT program is now developing a robotic tunnel inspection system, that should be both quicker and more thorough than human inspectors. Read More
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
