The first all-night weekend London Underground services will begin next year.

Northern line stations throughout Barnet will run the ‘night tube’ services overnight at weekends, except on the Mill Hill East and Bank branches.

The Mayor of London, Boris Johnson, and London Underground have announced the 24-hour service will begin in September 2015, and say it will reduce night time journey times in London by an average of 20 minutes.

In order to meet the expected demand, there will be six trains per hour through central London on all night tube lines.

Managing director of London Underground Mike Brown said: "Already over half a million Londoners use the tube after 10pm on Fridays and Saturdays, and the introduction of the night tube, which will cut journey times and open up new possibilities across the night time economy, is a historic step in our modernisation of the Underground."
