during the 1950s a new standard gauge line was built which did not pass through quorn. it was built on the western side of the dutchmans stern, mount arden and mount eyre. this line went from stirling north to brachina and then followed the original narrow gauge route through leigh creek and to marree. trains no longer went through the pichi richi pass or quorn. the only services now operating through quorn was freight from peterborough and hawker. as a result quorn lost its important railway business and in the 1980s the railway was completely closed as 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 joined 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.
