Architects from Gensler have released renderings of their plan to turn unused networks of the London Underground into “a stylish new subterranean route for pedestrians and cyclists,” CNN reports.
Renderings of the project, named London Underline, were created as a submission for the London Planning Awards. The plan includes using excess space underground for cultural and retail projects.
According to Dezeen, the name references the London Underground rail network and New York’s High Line park, suggesting that the city’s derelict mass transit networks “could provide the answer to overcrowding on other transport routes.”
However, a spokesperson for Transport for London, the city’s transport authority, told CNN that there aren’t many tunnels in subterranean London with “significant length that are not already part of out operational railway.”
