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
The Etheridge Railway, constructed by John Moffat's Chillagoe Railway and Mines Company between 1907 and 1910, was a significant component of an important, large-scale, privately built mining railway network in North Queensland and is important in demonstrating the widespread development of mining and transport infrastructure in this part of the State.
