After opening in 1853 the main line was operated by the
North London Railway (NLR). From 1865
Broad Street in the City of London was the most important passenger station connected to the line. From 1864 some trains went on to . The line between Willesden and Richmond carried services to and from Broad Street and was used by other companies serving Richmond. In 1869 the LSWR opened the direct connecting line from to Richmond via
Gunnersbury and services west beyond Richmond ceased. In 1868 Kew station (LSWR) was renamed
Kew Bridge, and the following year the LSWR opened a line from Richmond through Gunnersbury (at first called "Brentford Road") passing Turnham Green and Hammersmith. This gave a considerable boost to Richmond traffic, which was carried over the N&SWJR between Acton Junction (at the site of the later South Acton station) and Old Oak Junction, where the Hampstead Junction Railway connected. The Richmond line generated a more frequent train service on what is now the North London Line. The N&SWJR had been worked by the North London Railway, the Midland Railway and the LNWR jointly since its beginning. Under the '''''' (
34 & 35 Vict. c. cxcii) the line was taken over by those companies jointly. In 1874 the
Metropolitan District Railway ran through trains along the LSWR alignment to the West End of London and the City. The GWR, in 1870, had already operated a service via Hammersmith Grove Road onto the Metropolitan Railway tracks, but this was withdrawn after a few months. In an attempt to staunch the loss of business, the N&SWJR opened a new station at South Acton on 1 January 1880, renaming the Hammersmith station
Hammersmith & Chiswick. The new station had a bay for the Hammersmith branch line, which was extended to run independently alongside the main line for 19 chains to reach the station. shows a half-hourly service on the branch, but still changing trains to get to London. Quite apart from tramway competition, there were now several competing railways in the area: as well as the Hammersmith and City and the Metropolitan District Railway, the LSWR itself ran a service from Richmond via Hammersmith (Grove Road), alternately to Waterloo and Ludgate Hill via Kensington and Loughborough Junction. The LNWR took over the operation of the North London Railway on 1 January 1909 and replaced the passenger trains on the Hammersmith branch with a 48-seat steam railmotor; this operated a half-hourly service from 4 January 1909. Responding to competition from street tramways, three new halts were opened on the branch, at
Bath Road,
Woodstock Road and
Rugby Road. On 9 March 1913 the steam car was replaced by a petrol-electric railmotor, LNWR No. 9. The competing transport methods intensified and the branch was hopelessly uneconomic. The passenger service was withdrawn on 1 January 1917. Goods trains continued to serve a coal depot and asphalt plant at Hammersmith until 2 May 1965, after which the branch finally closed. The LNWR
electrified the N&SWJR main line to both Richmond and Kew Bridge in 1916, on the fourth rail d.c. system. This provided a more frequent and pleasanter travel experience and was very successful. The passenger service to Kew Bridge ended in 1940. After Broad Street closed in 1986 the N&SWJR line carried
North London Line services between Richmond and in east London. ==Current usage==
