Holborn Tube to trial standing-only escalators for second time

A standing-only trial on escalators at a London Underground station is to be extended after an initial test resulted in improved passenger flow. During a three-week experiment in November visitors to Holborn station were asked not to walk on escalators between 08:30 and 09:30 GMT. Queuing was reduced and 30% more people used the escalators during the trial. A new six-month trial starting on 18 April will have one of four escalators as always standing only.
