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.

The Mount Surprise railway station complex and other remaining evidence of cattle transportation at the main stations along the Etheridge Railway, such as cattle yards and loading banks, are important in demonstrating the role that the railway played in maintaining pastoral activity in the area before the construction of the bitumen "Beef Road" in the 1960s.
