At 05.45 on Sunday 17 September 2006, Heathrow Terminal 4 station will reopen to passengers, allowing them to once again travel direct to and from central London on the Piccadilly line.The Terminal 4 station has been closed for nearly 20 months for essential work as part of the project to extend the Piccadilly line to Heathrow Terminal 5.

The extension, funded by Heathrow Airports Ltd (a subsidiary of BAA), is progressing well and on target for completion by March 2008.

The shuttle bus service which has been operating between Hatton Cross and Heathrow Terminal 4 will remain in place for a week after the station reopens to allow passengers to make the transition back to the Tube.

Piccadilly line services will continue to run to Heathrow Terminals 1,2,3 via Terminal 4 as they did before the station closed.

Extensive communications are planned to inform passengers of the service changes, including train and station announcements, 'Heathrow by Tube' leaflets and 'Which station at Heathrow?' posters at stations and on trains.
