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
In January 1927 six bridges along the Etheridge line were destroyed by floods and the government sought to close the line beyond the lime works at Ootann, just south of Almaden. Due to public pressure the line was reopened in 1928, after the building of low-level bridges, but it was only maintained to standard suitable for use by railmotors. Steam trains did not operate on the line again until after the section from Almaden to Mount Surprise was reconditioned between 1949 and 1951 to allow the transport of heavier loads of cattle than could be pulled by diesel engines. This included adding rails on corners, regrading in six places, and one deviation. From the 1950s diesel-mechanical locomotives operated in multiple south of Mount Surprise to allow larger loads of cattle to be moved on the section of line to Forsayth. They were followed by diesel electric locomotives. This work assisted the cattle industry but the building of a bituminized "Beef Road" from Georgetown to Cairns reduced the use of the Etheridge line for cattle from the late 1960s. The use of steam locomotives to Mount Surprise ended in 1969.
