Map - Quorn, South Australia (Quorn)

Quorn is a small town and railhead in the Flinders Ranges in the north of South Australia, 39 km northeast of Port Augusta. At the, the locality had a population of 1,230, of which 1,131 lived in its town centre.

Quorn is the home of the Flinders Ranges Council local government area. It is in the state Electoral district of Stuart and the federal Division of Grey.

With its picturesque setting and heritage-listed buildings, the town is known for tourism and as a filming location, as well as being the terminus of the Pichi Richi Railway.

The town was surveyed by Godfrey Walsh in 1878 and named after Quorndon in Leicestershire, United Kingdom, as part of the preparations for building the railway line from Port Augusta northwards.

The railway line from Port Augusta to Quorn opened in 1879 and was subsequently extended north to Government Gums (Farina) in 1882, Marree in 1884, Oodnadatta in 1890 and Alice Springs in 1929. This railway line later became known as the Great Northern Railway and later the Central Australia Railway.

In 1917, Quorn became the crossroads of any north–south (on the Central Australian Railway to Oodnadatta) or east–west travel in Australia, when the Trans-Australian Railway was completed between Port Augusta and Kalgoorlie. This made Quorn an important town, given that any person travelling east–west or north–south in Australia would need to pass through Quorn. As a result, many fine buildings were built as the town expanded.

Quorn's role as a crossroads was lost when a standard gauge railway connection was opened between Port Pirie Junction and Port Augusta in 1937, meaning east–west trains bypassed Quorn. However, during World War II, Quorn was a vital service point for trains heading north to Alice Springs and carried over 1,000,000 troops heading to Darwin and on to Papua New Guinea. Trains services through Quorn peaked at over 50 per day during and immediately after the period of World War II. Services during this time also included coal mined at Leigh Creek being moved to the newly opened Playford A Power Station in Port Augusta.

During the 1950s a new standard gauge line was built that passed on the western side of The Dutchmans Stern, Mount Arden and Mount Eyre, from Stirling North to Brachina and then roughly following the original narrow gauge route through Leigh Creek and to Marree, thus bypassing Quorn. This bypass took away the last railway traffic through the Pichi Richi Pass, and the last major freight traffic through Quorn. The only services left operating through Quorn were freight between Peterborough and Hawker. As a result, Quorn's importance diminished and eventually in 1980s the railway was completely closed as the last freight was moved to road transport. One unusual aspect of the railway working from Peterborough to Quorn and then on to Hawker was the need for the engine to be turned and attached to the opposite end of the train when arriving at Quorn, as it was not a "through" station for the trip from Peterborough to Hawker.

In 1973, a group of railway enthusiasts assembled with the desire to preserve the unique bridges and stone work built in the previous century that formed the railway through the Pichi Richi Pass between Quorn and Stirling North. Thus the Pichi Richi Railway Preservation Society was formed. Although the intention was to just preserve the railway through the Pichi Richi Pass, they later acquired operable railway rollingstock and locomotives and today provide a tourist railway service through the Pichi Richi Pass from Quorn to Port Augusta. There is at least one book by preservationists showing the line in its heyday.
