There are planned closures this weekend on the London Underground’s Piccadilly Line and London Overground.
There is no service on the Piccadilly line between Wood Green and Cockfosters from today until Sunday September 1.
Replacement bus service PL5 is running during the day between Wood Green and Cockfosters via Bounds Green, New Southgate (for National Rail), Arnos Grove, Southgate and Oakwood.
During night Tube hours, use London Buses Route N91.
There is also no Piccadilly line service between Rayners Lane and Uxbridge for the same period. Travellers should use Metropolitan line services instead.
The closures are part of plans to introduce new trains. The line needs to be upgraded before the trains can be brought in.
On the Overground there is no service between Hackney Downs and Chingford all weekend.
Replacement bus service L3 is operating between Hackney Downs and Chingford via Clapton, St James Street, Walthamstow Central, Wood Street and Highams Park.
