The Heathrow Express departs from London Paddington Station, one of the city's most iconic and busiest railway hubs. The service is famous for being the fastest way to travel between Central London and the airport, with a non-stop journey time of just 15 minutes to Heathrow Terminals 2 and 3 (and an additional 6 minutes for Terminal 5). To find the platform at Paddington, look for the dedicated "Heathrow Express" signage near Platforms 6 and 7, which are usually the designated departure points. In 2026, the service remains a premium alternative to the Elizabeth Line, which also serves the airport but makes several stops along the way. Paddington Station itself is highly accessible via the Bakerloo, Circle, District, and Hammersmith & City London Underground lines, making it a convenient starting point for international travelers arriving from various parts of the city.
