A 15mph travelator could take people around London’s Circle Line quicker than trains currently do, according to a team of architects.
NBBJ, which has offices in London and around the world, has developed a proposal for a three-lane moving walkway to ferry passengers around the UK capital.
The system would see people step on and off a 3mph inside lane at Tube stations, with the option to move to the middle or fast lanes to quicken their journey.
Images released alongside the proposal show seats on the inside of the travelator, as well as food stalls on the other edge.
The practice said the concept came from an internal brainstorming session and it had no plans at present to progress it with Transport for London.
“NBBJ was inspired to develop this concept to open new possibilities for putting the fun back into travelling on the Underground, for tourists and Londoners alike,” it said in a statement:
“While the Circle Line travelator would likely become one of London’s most efficient and unusual modes of transport, one thing is certain: London requires creative thinking to build a healthy, happy and more liveable city for all.”
