Elizabeth and Piccadilly line services suspended due to repairs
Planned engineering works mean the Elizabeth and Piccadilly lines will be part-closed this weekend.
Transport for London (TfL) has said there will be no service between Acton Town and Uxbridge and no service between Heathrow Terminals 2 and 3 to Terminal 5 on both days on the Piccadilly Line.
TfL said the Piccadilly Line will serve Terminals 2, 3 and 4, with buses available for Terminal 5.
On the Elizabeth Line there will be no service all weekend to Heathrow, or between Paddington and Abbey Wood or Stratford but trains will still run between Liverpool Street and Shenfield.
