From its creation to the present day, London Underground's 160-year history has been an eventful one. First Capital Connect is a railway company created on 1 April 2006 following the takeover of the wagn (West Anglia Great Northern Railway) and Thameslink franchises. Work continued on the rest of the northern extension. The City and South London Railway Act, 1900, approved on 25 May 1900, [42] gave permission to enlarge the station tunnel at Angel to a diameter of 9.2 m (30 ft) [43] [44] and the rest of the extension opened on 17 November 1901, [40] with stations at:The LBSCR scheme, authorised in 1903, pioneered main-line rail electrification in the UK, and the first electric train ran on 1 December 1909. For the following three years, steam trains alternated with electrics, the latter operating every 15 minutes from 7.30am to midnight. Passenger numbers had fallen on introducing electric tramways in South London by 1.25million in six months. In the first year of the rival line's electric operation passengers increased from 4million to 7.5million. The electrification used the overhead system at 6700 V AC, supplied by a power station at Deptford. [1] After creation of the Big Four railway companies, the Southern Railway installed standard third-rail 660 V DC supply on 17 June 1928. [1] Pre-extension route

LBSCR passenger service began 13 August 1866 between Loughborough Park and London Bridge. It was extended to Victoria on 1 May 1867. The bill was rejected on the grounds that the extension failed to make a connection to the existing line. In November 1891, the C&SLR published details of a revised bill for the extension to Islington. The company had recognised the deficiencies of its King William Street station and, just a year after the line had opened, planned to construct a new pair of tunnels to bypass the problematic northern section. The bill was enacted as the City and South London Railway Act, 1923 on 2 August 1923. Parallel negotiations with the Southern Railway over the proposals curtailed the extension at Morden where a large new depot was also constructed. The Morden extension opened on 13 September 1926, with stations designed by Charles Holden at: Clapham South, Balham (opened on 6 December 1926), Trinity Road (Tooting Bec), Tooting Broadway, Colliers Wood, South Wimbledon and MordenThe London Overground also runs on this line as part of the Clapham Junction – Dalston Junction / Highbury & Islington service. Trains also call at Wandsworth Road and Clapham High Street stations. Closed for major reconstruction works, including wider tunnels [4], before its merger with another of the Group's railways.
