The Under Line: Derelict London Tube Tunnels as Public Paths

Tapping unused sections of the London Underground,  this bold proposal would create a network of subterranean paths for pedestrians and cyclists as well as spaces for pop-up shops, cafes and cultural events, all situated in stations and subway stretches of rail currently sitting idle and empty.

In the spirit of New York’s proposed Low Line, the plan involves main disused tunnels serving as primary areas for circulation and interaction. Simultaneously, putting existing but unused infrastructural voids to better use, the design calls for old reservoir chambers and exchanges to connect these larger and more open sections of the Tube.

Architects at Gensler, the firm behind the idea, developed it to address a series of issues in the densely-populated capital of England, including bicyclist fatalities on surface streets, a lack of public space and ease of movement across the city.

As a bonus, special panels lining the interior of these underground spaces would be used to generate kinetic energy from people passing through and walking on surfaces, obviating the need for external power sources. Indeed, the technology for this system already exists, and this would be a great potential application for both cost and sustainability reasons.

The development process could also be incremental, moving in stages to make transition and restoration costs more manageable and to test usage patterns. The default plan is to start with voids between Green Park and Holborn, working stations that could provide access to unused portions of the Tube spanning them. In turn, tying these spaces into the existing Underground network would make them more accessible to visitors coming into the city and locals alike.

Unlike other conceptual projects for London, like the SkyCycle,or serious proposals, like the Garden Bridge, very little would have to be added or displaced for this reprogramming approach to work. The Under Line may also borrow a bit of inspiration from this clever idea to transform Paris Metro stops into event spaces.
