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.
