Train and Tube
There are three ways to get to Terminal 4 by rail – the London Underground (Tube), the Heathrow Express, and the Heathrow Connect. Each service offers different pricing and comfort levels.
Terminal 4 has its own station on the London Underground, in the basement of the terminal. It’s clearly signed from the terminal. Piccadilly line trains run to Terminal 4 every ten minutes, or even less at peak times. Journey time between Terminal 4 and central London is just under an hour. This is the most cost effective way to travel to Terminal 4 from London, with a ticket costing £2.40 on a pre-paid Oystercard, or £4.50 in cash. From central London, tubes run to Terminal 4 from 05:45 (07:27 on Sunday) until 23:09 (22:42 on Sunday). The Piccadilly line runs to various key central London destinations, including Piccadilly Circus, Covent Garden, and Kings Cross.
The Heathrow Express runs from London’s Paddington station, in the western part of the city centre. There is no dedicated Heathrow Express station for Terminal 4 – you’ll need to get off the train at Heathrow Central and take the Heathrow Express shuttle bus transfer (this should only take a few minutes). This is the fastest rail link, but also the most expensive, with a standard single fare costing £18. Trains leave Paddington every 15 minutes between 05:10 and 23:25. The Heathrow Express does provide excellent facilities to compensate for the high cost. On board, you’ll find TV screens, free wireless internet, modern airline style seats and lots of baggage storage.
The Heathrow Connect also runs from Paddington, stopping at west London suburban stations including Ealing Broadway, West Ealing, Hanwell, Southall and Hayes and Harlington. It terminates at Heathrow Central, but you can take the Heathrow Express shuttle bus for free to reach Terminal 4. Trains run every 30 minutes and take around 25 minutes, costing £7.90 from Paddington. They run between 04:42 and 23:03.
