The main Terminal 5 departures/arrivals building at Heathrow Airport is the largest free-standing structure in the UK. It has five storeys above ground and more below, including its own Tube station on the Piccadilly Line (central London around 50 "“ 60 minutes). This main terminal is where all the 'A' gates are. Two further sets of Gates, 'B' and 'C', are connected to the main terminal by dedicated connecting shuttle trains that run every minute or so. Terminal 5 is designed to handle around 30 million passengers per year and their luggage is moved around on 11 miles of conveyor belt. This extra capacity will allow Heathrow to handle 90 million passengers per year.
