It is the unloved Underground line more prone to delays than any other.
Now a firm of London architects has come up with a radical solution
to the Circle line’s problems — replace it with a high-speed travelator.
The team behind the idea claim that a three-lane moving walkway
through the line’s 17-mile circuit could shorten journey times, boost
capacity threefold and health.
Passengers would step from “feeder” walkways
at 3mph onto a yellow “slow lane” going at the same speed through
stations but accelerating to 6mph and then 9mph in lit tunnels. There
would also be a “middle lane” , coloured orange, with a top speed of
12mph, and a 15mph red “fast lane”.
NBBJ researchers calculate the travelator would allow up to 55,000 people to use the Circle line at any one time.
Britain’s first travelator was installed at Bank station 55 years
ago. In Paris, a “trottoir roulant rapide” opened at Montparnasse
station in 2002, moving at 6mph over 180 metres. It was slowed to 3mph
after a spate of .
