Etheridge railway line
The railway stations at Mount Surprise, Einasleigh and Forsayth and the route of the Etheridge Railway between Mount Surprise and Forsayth, including surviving railway buildings, rails, sidings, turning forks, loading banks, stone pitched bridges and culverts, stone cuttings, sandboxes, water tank, signage, and signals and points infrastructure, are important surviving evidence of the efforts of the Chillagoe Railway and Mines Company to supply copper ore to its smelters at Chillagoe.
Etheridge railway line
Around 1917 a lime burning business started at Ootann, south of Almaden, using old kilns used during the construction of the railway, and a siding was installed about 1918. Ootann was the limit of steam operation from 1927 to 1951. It had a shelter shed by 1935, and an overhead gantry for loading lime. The present main line was originally the siding, as the main line was moved to install the gantry. Gelaro at had a crossing loop, levers and a shelter shed by 1969. Bullock Creek at had a siding and railway phone by 1916, and was the site of a permanent fettler's (rail line maintenance worker's) camp by 1932. There was a side loading bank and shelter by 1935, and private cattle yards by 1951. A water tank was present, although this no longer exists. The loading of cattle at Bullock Creek ceased in late 1991.
