London Underground is suspending all non-essential engineering works in an attempt to ease Olympic and Paralympic congestion.
After this weekend, no planned works will take place until mid-September to reduce the risk of delays.
Transport for London is predicting that more than one million extra passengers a day will use the capital’s public transport network during the Games.
Mike Brown, London Underground’s managing director, said: “As London continues its transformation into a huge sporting and cultural venue, there will be no planned engineering work after this weekend until mid-September and all essential maintenance will be undertaken overnight.
“We’ve made a range of improvements to the network to improve reliability and many extra services will be running throughout.”
Other changes to Underground services will include:
- Running last trains westbound from the Olympic Park at 1.30am, and last trains on all lines running about an hour later than usual
- Running trains later from Stratford and central London on opening ceremony night, July 27, with last trains at 2.30am
- Running a third peak on some Tube lines, with peak-level services running on some lines between 10pm and 11.30pm.
