Office of the Divisional Superintendent, Peterborough - South Australian Railways (GA191)

The Peterborough Division was created as a result of the opening of the Port Pirie to Crystal Brook line in December 1875. This was further developed in stages up to June 1887, when the Peterborough to Cockburn Section was completed. later stages were completed during the period 1910-1937.

The division comprised three gauges, 5ft 3in, 4ft 8in and 3ft 6in. During 1963 approval was announced for the standardization of the Port Pirie to Cockburn line which also covered the conversion of the Terowie to Peterborough line. The project was undertaken as part of the work included in the 1949 standardization agreement between the Commonwealth and South Australian governments.

During 1968 agreement was reached with the Commonwealth, New South Wales and South Australian governments to extend the section between Cockburn and Broken Hill. This work was also included under the 1949 agreement. Once the conversion was completed it allowed a standard gauge train to operate between Sydney and Perth via Port Pirie.

Although the South Australian Railways Commissioner ceased in 1975 the Peterborough Division continued to operate until March 1978 when Australian National Railways took over the running of non-urban railways in South Australia.
