Epsom and Leatherhead. In 1859 the friendly Wimbledon and Dorking Railway opened from Wimbledon, running alongside the main line as far as Epsom Junction, at the site of the later Raynes Park station, then diverging to Epsom, joining there the Epsom and Leatherhead Railway, operated jointly with the London, Brighton and South Coast Railway. Parts of Kingston were from station but in 1863 a line from Twickenham to Kingston railway station (England) was opened, forming the first part of the Kingston loop line. A single-track Shepperton branch line was laid in 1864, reaching westwards up the Thames Valley. In 1869 the Kingston loop line was completed by the south-eastward extension from Kingston to Wimbledon, with its own dedicated track alongside the main line from Malden to Epsom Junction (Raynes Park), where it joined the former Wimbledon and Dorking Railway lines. London terminal stations Nine Elms The company's first London terminus was at Nine Elms on the southwestern edge of the built-up area. The wharf frontage on the Thames was advantageous to the railway's objective of competing with coastal shipping transits, but the site was inconvenient for passengers, who had to travel to or from London either by road or by steamer. Passenger steamboats left from Old Swan Pier, Upper Thames Street, not very close to the City centre but the best that could be managed, one hour before the departure of each train from Nine Elms, and called at several intermediate piers on the way. To take one hour and only get as far as the starting point of the train was clearly not good enough, not even 150 years ago. Extending to Waterloo The "Metropolitan Extension" to a more central location had been discussed as early as 1836, and a four-track extension was authorised from Nine Elms to what became Waterloo station, at first called Waterloo Bridge station. Opening was planned for 30 June 1848, but the Board of Trade inspector Captain Simmonds was concerned about the structural stability of Westminster Bridge Road Bridge, and required a load test. This was carried out on 6 July 1848, and was satisfactory. The line opened on 11 July 1848, together with the four tracks from Nine Elms in to Waterloo. Waterloo station occupied three-quarters of an acre (0.3ha); there were two centre lines, and four other lines serving roofed platforms 300ft (91m) long, soon after extended to 600ft (182m). They were
