The introduction of all-night services on Fridays and Saturdays is part of a strategy for the future development of the Underground network, which will include the rollout of passenger Wi-Fi at all sub-surface stations by the end of next year, improved access for passengers with disabilities, and the introduction of contactless bankcard payment from next year.

LU has also outlined plans to close all of its remaining ticket offices on the grounds that less than 3% of all Tube journeys now involve a visit to a ticket office. It is planned to redeploy ticket office staff to other roles at stations, although it will result in a net reduction of around 750 staff. Nonetheless, LU says there will be a 30% increase in the number of staff in ticket halls at major stations, while dedicated staff equipped with mobile devices will be on hand at smaller stations.

The proposals are expected to generate savings of around £50m per year.
