From today, customers at Holborn Tube station will be asked to stand on both sides of two 'up' escalators as Transport for London (TfL) launches a six month trial to ease congestion at the station.

New signs and customer information are on display to encourage customers to stand on both sides. The third 'up' escalator is also available for people who still want to walk up.

The six month trial follows a three week trial that took place last year, which found that standing on both sides of the escalator reduced congestion by around 30 per cent.

Peter McNaught, Operations Director at London Underground, said:

'I look forward to this new pilot starting today. The etiquette on London Underground is for customers to stand on the right of escalators, allowing others to walk on the left. However, few customers choose to walk on longer escalators such as Holborn, so much of the left-hand-side is unused. We hope that this can lead to improving congestion at Holborn, making journeys easier for all of our customers.'

Tass Mavrogordato, CEO of inmidtown, said:

'The Midtown area has seen a substantial transformation as the destination of choice for businesses to locate in, meaning that the area is very busy at peak hours. It's great to see initiatives like the TfL escalator scheme underway at Holborn Tube station - a practical step that will provide some relief at one of the busiest stations on the Tube network.'

Different messages have been developed by the behavioural science department at London School of Economics and will be tested at different times to see which works best. These include standard instructions to customers and 'light' messages that play on words about standing.

These will be displayed in various ways, including using a talking projection of a staff member, electronic versions of the triangular 'stand on the right' signs that customers pass as they travel up the escalator, signs on the floors, footprints on the escalator steps, handprints on the handrails and station announcements.
