Commuters using Stratford Tube Station could face disruption as ticket offices are set to close permanently by the end of April.

On April 7, the north ticket hall’s ticket windows, at the entrance to Westfield, will close and work is expected to last for up to one month.

From April 27, the office in the east ticket hall, which is next to the bus terminal, will also be closed.

The work will involve the installation of additional ticket machines and is expected to last up to three months.

London Underground’s chief operating officer Nick Brown said the closures are part of a “phased programme” across London in which staff will be moved to ticket halls, gate lines and platforms to offer assistance where it is most needed.

“Our customers and our staff are at the centre of our approach to customer service,” he said. “Staff are being equipped with the latest technology to help customers with their journeys.”

Ticket office staff will be on hand to assist train users with “smarter” ticket machines, which will offer guidance in 17 different languages.

The station will remain open throughout and the improvement in efficiency is expected to save £50million a year and £270m by 2020/21, according to Transport for London.
