From January 7 2005, London Underground Piccadilly line trains heading for Heathrow's Terminal 4 station will not go beyond Hatton Cross.

Passengers will have to take a shuttle bus from Hatton Cross to Terminal 4.

Piccadilly line services to the Heathrow Terminal 1, 2 and 3 station will not be affected, although there will be no direct service to this station on the weekend of January 8 and 9, 2005.

The long-term closure of Terminal 4 station is due to work on the Piccadilly line extension to the under-construction Heathrow Terminal 5. London Underground have said that during the 20-month period, the Terminal 4 journey should 'only take about five minutes longer than now', while trips to Terminal 1, 2 and 3 will be slightly quicker.

Around 2,500 people travel to and from Terminal 4 by Tube each day.
