[pop-up] urbain on 09 Sep 15"Architecture firm NBBJ has unveiled a conceptual plan to turn London Underground's Circle Line tunnel into a 17-mile-long moving walkway. NBBJ's concept suggests replacing all of the trains on the underground rail network's Circle Line route with a set of three travelators, which would carry commuters along the route. Each of the three adjacent walkways would travel at a different speed, allowing commuters to start out at a manageable three miles per hour (mph) before moving across lanes of increasing speeds, up to the fastest at 15 mph."
