A subterranean network of cycle superhighways could help ease London's congestion problems. The scheme, known as London Underline, would repurpose disused tube tunnels, stations and reservoir chambers to reduce the number of cyclists on the road in the centre of the city.

The scheme has been developed by design firm Gensler and recently won best conceptual project at the London Planning Awards. As well as an underground network for cyclists there would also be space for pedestrian walkways and shops. Judges said the design had the potential to "significantly" alleviate congestion between popular destinations.


Power for the network would be created using kinetic energy -- turning the footsteps of pedestrians using the tunnels into electricity. The kinectic energy technology has been developed by PaveGen.

Gensler has identified two main tunnels it could use, one between Green Park and Charring Cross Road and another between Holborn and Aldwych. The disused tunnels once formed parts of the Jubilee and Piccadilly lines. Tunnels near Stockwell and Goodge Street have also been identified as potential sites for parts of the network.

Kinetic energy would make the network self-sufficient with the rental of retail spaces paying for its upkeep. Ian Mulcahey, co-director of Gensler London said it was necessary to think creatively to improve transit in London. "The adaptation of surplus and under-utilised tube and rail tunnels could provide a quick and simple addition to our infrastructure network," he said.
