High Quality Content by WIKIPEDIA articles! Paddington station, also known as London Paddington, is a central London railway terminus and London Underground station complex in the Paddington area of central London, England. The site is an historic one, having served as the London terminus of the Great Western Railway and its successors since 1838. Much of the current mainline station dates from 1854, and was designed by Isambard Kingdom Brunel. 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. Despite its historic nature, and the wish to preserve many of its features, the complex has recently been modernised, and has a new role as the terminus of the dedicated Heathrow Express service. The complex is in Travelcard Zone 1.
