Tube trains will link Waterloo with Bank until 12.30am six days a week after Mayor of London Boris Johnson announced plans to extend the Waterloo & City line's operating hours.
"The Tube is already more efficient than ever before, zipping passengers across our city to their homes and workplaces like a well-oiled machine," said Boris Johnson, Mayor of London.
"Now we are increasing services on the Waterloo & City and Central lines, giving passengers what they have asked for and helping to further ease congestion."
From Monday 16 September passengers will be able to use Waterloo & City line trains during weekdays and Saturdays until 12.30am at night – up to six hours later than they can currently.
More trains will also operate on weekday evenings – with a train available approximately every three and half minutes until around 9.30pm, then every six minutes until 11.30pm, followed by a 10 minute service for the last hour.
On Saturdays, instead of closing the line after 6.30pm, trains will keep running until 12.30am with a train every six minutes until around 11.30pm and for the last hour a train every 10 minutes.
