Roseworthy is a small town in South Australia, about 10 km north of Gawler on the Horrocks Highway. At the 2016 census, Roseworthy had a population of 994. Roseworthy has a large grain storage facility consisting of both storage silos and bunkers for grain grown in the surrounding areas, and grain is now taken by road transport to Port Adelaide for export where it was once taken by rail. Roseworthy is the junction of the former Peterborough railway line and Morgan railway lines, both constructed as broad gauge railway lines (although the Peterborough line was originally narrow gauge from Terowie to Peterborough), and remained that gauge for their entire service. Both lines were originally built to support export from copper mines, respectively at Burra and Kapunda before being extended bey
