Etheridge railway line
The Etheridge Railway line, which branches off the Mareeba-to-Chillagoe railway at Almaden and heads south for to Forsayth via Mount Surprise and Einasleigh, was built between 1907 and 1910 by the Chillagoe Railway and Mining Company as a private railway line. The same company constructed the railway line from Mareeba to Chillagoe and Mungana between 1898 and 1901. The Etheridge line was built cheaply, with lighter rails and fewer earthworks than the Chillagoe line, to supply ore to the Chillagoe Company's under-utilised Chillagoe smelters. The Chillagoe Company was part of the business empire of John Moffat, and between 1880 and 1914 much of the economic activity of North Queensland was driven by the railways and mining towns created by Moffat's enterprises. The remaining built infrastructure at stations along the Etheridge Railway provides examples of the type of buildings erected by the Chillagoe Company for its railway network.

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.
