The London Underground is the oldest subway system in the world. Opening in 1863, the network has grown to become one of the most iconic and advanced of its kind.
With just under 600 trains running on its 248 miles of track at its busiest hours, the man and machine power required to ensure a seamless operation is immense.
The control centre is located in Central London, but for security reasons we were asked not to disclose the centre's exact location in the capital.
From here they can monitor almost everything going on around the network.
The displays provide the information needed to know what is happening on all of the London Underground's 14 lines.
Each station is represented by a yellow block, while each train is shown as a rectangle which is colour coded to show how full that particular vehicle is. Each set of signals is also displayed for the lines that still use them.
