Tube geek (14)Going Underground
Only 45% of the London Underground network is actually underground. The earliest underground railways were shallow sub-surface tunnels, dug using the cut and cover method beneath the roads of central London. By the time later lines came to be built there was only room beneath the ground for deep level tubes. But out in the suburbs the trains arrived in advance of the houses, so there was plenty of space on the surface and no tunnels were required. Today London has a total of 113 miles of tube tunnel (20 cut and cover, and 93 deep level) - an underground nirvana which no mobile phone signal can yet penetrate. So, where are these tunnels? Here's my line-by-line guide to subterranean travel (compiled via geoff's special underground map). I hope it's correct, near enough...
