London Paddington station is a major National Rail and London Underground station complex in the Paddington area of central London, England. Much of the current mainline station dates from 1854, and was designed by Isambard Kingdom Brunel as the London terminus of the Great Western Railway. The site was first served by underground trains in 1863, and was the original western terminus of the Metropolitan Railway, the world's first underground railway. Today, the mainline station is served by trains from First Great Western, Heathrow Express, Heathrow Connect and Chiltern Railways and Underground services are provided by the Hammersmith & City, Circle, District and Bakerloo lines and is used by approximately 29 million mainline and 48.55 million Underground passengers each year.
