The Picton–Mittagong Loop Line is a partly disused railway line between the towns of Picton and Mittagong in the Southern Highlands of New South Wales, Australia.
The Picton–Mittagong line was opened in February 1867 as part of the Main South line.
The line ran north-northwest from Picton, over the Picton Viaduct, across the Great South Road before heading northwest. It then headed west-northwest through a 180-metre tunnel in the Redbank Range.
Stations were constructed at Redbank (1885), Couridjah (1867), Buxton (1893), Balmoral (1878), Hill Top (1878), Colo Vale (1883) and Braemar (1867). There were a number of smaller stops, sidings and passing loops along the line, as well. North of Hill Top, the cutting through Big Hill was for many years the deepest in Australia.
To service the line, Picton became a busy station with a locomotive depot for bank engines, dormitories for train crews, and goods sidings.
The line, while gently curved, had gradients as steep as 1 in 30. It was also a single-track line, and even though deviations were constructed between Hill Top and Colo Vale to ease grades, these factors combined to create a bottleneck, as rail traffic increased. In July 1919 a new double track alignment with ruling 1 in 75 grades between Picton and Mittagong via Bargo opened. The original proposal was for the line to be shifted considerably further eastwards from Appin to Bargo avoiding Picton. This was strongly opposed in Parliament by Picton local interests, hence the 180° curve that cicumnavigates the town. The old line, now renamed the Loop Line, continued to be served by passenger services until August 1978. Most services were operated by 30 class locomotives and later CPH railmotors, although there was a Sunday evening service to Sydney hauled by main line locomotives as recently as 1973.
