Adelaide Metro Seaford railway line. It reached Christie Downs in 1976, Noarlunga Centre in 1978, with a further extension to Seaford in 2014. The beginnings of the Victor Harbor line was a horse-drawn broad () gauge tramway built from the port of Goolwa on the Murray River to an ocean harbour at Port Elliot in 1854. This line was used to move freight between the shallow-draft vessels navigating the Murray, and coastal and ocean-going vessels, without either having to traverse the narrow and shallow mouth of the river with unpredictable currents. It was later extended from Port Elliot to Victor Harbor in 1864 and from Goolwa to Strathalbyn in 1869. It was extended to Mount Barker Junction on the South Line in 1884 and strengthened to carry steam trains. A branch from the South Line between the Mount Lofty Ranges and Murray River was built to Monarto and Cambrai in 1886. It was shortened to Apamurra near Palmer before being converted then closed briefly due to the standardisation of the Adelaide – Melbourne line in 1995. The line was then converted to standard gauge later in 1995 until it then closed again in 2005. In the Murray Mallee, the Pinnaroo line was built from Tailem Bend to Pinnaroo in 1906. This was connected with the Victorian Railways at the Victorian border and Ouyen by 1915. The South Australian part of this line was converted to standard gauge in 1998 to reconnect it with the Adelaide – Melbourne line. This created a break-of-gauge at Pinnaroo. The last traffic on the line was transporting grain from silos to Port Adelaide. Viterra announced that no more grain would be carried by rail on this line after 31 July 2015, with the 2015 harvest to be entirely transported by road. The Barmera railway line opened from Tailem Bend through Karoonda to Wanbi on 6 January 1913, extended to Paruna on 1 May and Meribah on 7 May 1913 (both in the Brown's Well district). Even while this line was still being built, the Government of South Australia approved several spur lines from it to open up over a million acres of farmland. These were: Waikerie railway line Karoonda north to Waikerie (opened December 1914)closed 14 March 1990 to Galga, 4 March 1994 to Karoonda Alawoona north to Loxton (opened February 1914) closed 2015 Brown's Well north to Paringa (opened October 1913), closed to Alawoona
