Liverpool Lime Street is a terminus railway station and the main station serving the city centre of Liverpool. Opened in August 1836, it is the oldest still-operating grand terminus mainline station in the world. A branch of the West Coast Main Line from London Euston terminates at the station, as does the original Liverpool and Manchester Railway. Journeys from Lime Street cover a wide range of destinations across England, Scotland and Wales. Having realised that their existing Crown Street railway station was too far away from the city centre, the Liverpool and Manchester Railway commenced construction of the more central Lime Street station in October 1833. Designed by John Cunningham, Arthur Holme and John Foster Jr, it was officially opened in August 1836. Proving to be very popular with train commuters, expansion of the station had become necessary within six years of its opening. The first expansion, which was collaboratively produced by Joseph Locke, Richard Turner, William Fairbairn and John Kennedy, was completed in 1849 at a total cost of £15, 000 (equivalent to £1, 660, 000 in 2021). During 1867, work upon a further expansion of Lime Street station commenced, during which time the present northern arched train shed was built. Designed by William Baker and Francis Stevenson, the train shed was the largest such structure in the world upon completion, featuring a span of 200 feet (61 m), as well as the first to make extensive use of iron. During 1879, a second parallel southern train shed was completed. During the 1970s, a new urban rail network known as Merseyrail was developed, while all other long-distance terminal stations in Liverpool were closed, resulting in such services being centralised at Lime Street for the whole city. In October 2003, the Pendolino service operated by Virgin Trains West Coast was ceremonially unveiled at the station, introducing a faster service between Liverpool and London.
