from Sydney, as well as local services. At Coniston the double track ends with an electrified branch line heads east to Port Kembla. At Unanderra, the line to Moss Vale branches off to head west over the Illawarra escarpment to join the Main South line. The line continues south through Kembla Grange Racecourse where a simple platform serves the adjoining racecourse. The line then reaches Dapto where a passing loop is provided. Dapto was the southern extent of electrification until 2001. The line passes south through Albion Park (where another crossing loop is provided) to reach Kiama the extent of electrification. South of Kiama, the line continues as a single track non-electrified line through rolling dairy pastures via several tunnels to the towns of Gerringong and Berry before arriving at its terminus at Bomaderry on the northern bank of the Shoalhaven River. At Bomaderry, sidings connect to the Manildra Group's starch mill. An extension of the line to the Jervis Bay area had been proposed as early as 1911. In April 1971, the State Government announced the line would be extended to Jervis Bay if a proposed steelworks were built. Branch lines Bankstown line The Bankstown line was initially opened as a branch line from the Illawarra Line to Belmore Station in February 1895, although it was soon extended through to Sefton to the Main South line on 16 July 1928. East Hills line The East Hills Line was first recommended to the Parliamentary Standing Committee on Public Works in 1916, as an alternative route when the Bankstown Line was being constructed, the line opened to Kingsgrove on 21 September 1931, and to East Hills three months later on 21 December 1931. It was connected to the Main Southern line near Glenfield station on 21 December 1987. The East Hills line experienced a major change in 2000 when the Airport line opened. This saw most East Hills trains using the new line to access the city, providing relief to the section of the Illawarra line between Sydenham and the city. Cronulla line A single track tramway line between Sutherland and Cronulla, with four stations and a goods siding, opened on 12 June 1911. By 1932 the tramway had closed. Competing bus services had begun to run with unrestricted competition, and the tram line by this time was so full with services that trams often ran late due to holdups at
