To allow for line upgrades for the new train fleet the Piccadilly Line is closed between Cockfosters and Uxbridge via Central London on
Tuesday 18 to Thursday 20 August, Tuesday 25 to Thursday 27 August, also Saturday 22 August to 1400
This means that the Piccadilly line will only run between Heathrow and Acton Town. Change at Acton Town for District Line services into central London. For direct journeys use the Elizabeth Line depending on destination.
