December 1990 then Tailem Bend August 2015 The Peebinga railway line east from Karoonda covering the gap between the Pinnaroo and Brown's Well lines, opened 18 December 1914, closed 7 December 1990. The government expected these lines to not recover the cost in the short term, but to open up land for farming wheat to "strengthen the backbone of South Australia". They were built using second-hand rails, and were the first in the state to use steel sleepers. Later, the Moorook railway line was opened from Wanbi to Yinkanie (near Moorook) in September 1925, but closed in 1971. In 1928 the line was opened from Paringa to Renmark and Barmera; it closed in 1990. The last of these lines was the Loxton railway line which was converted to standard gauge in 1998. It closed with the transfer of the grain traffic to road after July 2015. Viterra announced that no more grain would be carried by rail in the region after 31 July 2015, with the 2015 harvest to be entirely transported by road. Southern narrow gauge lines In 1876 a narrow gauge line known as the Kingston-Naracoorte railway line was built from Kingston SE to Naracoorte. In 1879, a railway was built between Beachport, Millicent and Mount Gambier. In 1887 they were linked by a line from Mount Gambier to Naracoorte and Wolseley on the broad gauge Melbourne–Adelaide railway, creating a break-of-gauge junction at Wolseley. It later had a branch line added from Wandilo to Glencoe. The Mount Gambier-Heywood railway line, a broad gauge line, was opened between Mount Gambier and Heywood near Portland in 1917. From 1953 to 1956, the southeastern lines were converted to broad gauge, with the exception of the Beachport – Millicent and the Wandilo – Glencoe line, which were closed down in 1957. The Kingston – Naracoorte was closed on 28 November 1987. The other southeastern lines, including the line to Heywood, have been out of use since the standardisation of the Adelaide – Melbourne and Maroona – Portland lines on 12 April 1995. There are regular calls for their standardisation. Northern lines Broad gauge lines In 1857 the Gawler line was built to Gawler station, which was rural at the time, and extended to Roseworthy, Kapunda in 1860. The main line left the Kapunda branch at Roseworthy and proceeded to Hamley Bridge, Riverton, Burra in 1870. The Kapunda branch was extended to Morgan
