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 was constructed in the most economical way possible using timber for the bridges, sharp curves, steep grades and light ( pound per yard) rails. There were fewer earthworks than on the Mareeba to Chillagoe line, and minimal ballast was used under the sleepers. Despite controversy, the Chillagoe Company changed the line terminus from Georgetown to Charleston (Forsayth) because it was thought that the mines near Charleston were more promising than those near Georgetown.
