Celebrating 150 years of the London Underground

Look through the window as you travel between Tottenham Court Road and Holborn on the Central Line and you'll see a station - where no passengers have alighted since 1932. This used to be British Museum station. Travel on the Piccadilly Line between Green Park and Hyde Park Corner, the tunnel wall changes from cast iron tubing to bricks. This also used to be a station. Down Street, closed in the same year as British Museum. These stations are often referred to as ghost stations.
There are about 40 abandoned or relocated stations on the Underground network along its entire 255 miles (408Km) of trackway - some subsurface and some above ground. Some have vanished without trace whereas others are almost intact, grimey time capsules of the era when they were closed.
The world famous underground map (well, technically it's a diagram not a map), was originally designed by Harry Beck in 1931.
