King's Cross railway station, also known as London King's Cross, is a passenger railway terminus in the London Borough of Camden, on the edge of Central London. It is in the London station group, one of the busiest stations in the United Kingdom and the southern terminus of the East Coast Main Line to North East England and Scotland. Adjacent to King's Cross station is St Pancras International, the London terminus for Eurostar services to continental Europe. Beneath both main line stations is King's Cross St Pancras tube station on the London Underground; combined they form one of the country's largest transport hubs. The station was opened in Kings Cross in 1852 by the Great Northern Railway on the northern edge of Central London to accommodate the East Coast Main Line. Famous services were the Flying Scotsman and locomotives such as Mallard. The £500 million restoration plan announced by Network Rail in 2005 was approved by Camden London Borough Council in 2007. It involved restoring and reglazing the original arched train shed roof and removing the 1972 extension at the front of the station and replacing it with an open-air plaza
