How to get to London City centre from Heathrow Airport (LHR)-
From Heathrow the centre of the city is well connected by tube (underground), rail, taxi, bus. There are manned information counters from where one can obtain details about travel in the city and London-sight seeing. Also there are brochures and maps at various places in the airport which is really helpful for a new visitor to the city.
Traveling and sight seeing on your own in London is very convenient. From Heathrow one can take theHeathrow Express to Paddington Station. It takes about fifteen minutes from Terminal 1,2, & 3 and about twenty-five minutes from Terminal 4. Paddington is a hub – you can get the tube and buses to other parts of the city from the station itself. Four of the Tube lines pass through Paddington viz. Bakerloo, Hammersmith & City, District and Circle. The buses to and from this place are route numbers 7, 15, 23, 27, 36, 205, 436 and 705. Another way to get to central London is through the Heathrow Connect. This also takes about 25 minutes to Paddington, but it is cheaper than the Express.
The new terminal (T5) at Heathrow Airport opened in March 2008.
Apart from getting to Paddington using the above, there are other ways to get to central London. The airport is connected to the Tube and also has bus services running. In the airport the signs would lead one to a ramp near the exit through which you descend to the Rail and Tube services. One can take the Piccadilly line of the London Underground and then change according to destination. For instance one can change to the Jubilee Line from the Piccadilly line by getting down at Green Park station. The main lines of the Underground are Bakerloo, Central, Circle, District, East London, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria, Waterloo & City.
If one is coming TO Heathrow from the west, then one option would be RailAir. RailAir runs a coach service from Reading to Heathrow Terminal 1, 2 and 3 with a free transfer to terminal 4. Sight seeing in London is very convenient if one uses the London Underground. Many of the tourist places and landmarks are covered by it.
