Chillagoe Railway &amp; Mining Co.
After a number of proposals had been made for the route of a railway to the Etheridge field, construction of the Etheridge Railway finally commenced in 1906 from Almaden to Mount Surprise on the Mareeba to Chillagoe line. The railway was opened to Mount Surprise in May 1908, and through to Einasleigh on 8 February 1909, a total of 101 miles. The final 41 miles from Einasleigh to Forsayth were not opened until 5 February 1911, construction having proceeded slowly due to union unrest and uncertainty within the mining industry generally.
Etheridge railway line
The route and formation of the line between Mount Surprise and Forsayth, with its steep gradients and sharp curves and accompanying lack of earthworks, along with the relative lack of steel, stone or brick bridge piers and abutments, demonstrates the nature of a railway line that was built as economically as possible. The section of the railway over the Newcastle Range and through the Delaney Gorge, although it has more earthworks and stone cuttings than any other section of the railway, also demonstrates a cheap form of railway construction, due to its sharp curves and steep gradients.
