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.
Edrom
Edrom had a railway station on the North British Railway's Berwickshire Railway (opened 1863). The railway line ran from Reston to Earlston, joining the East Coast Main Line to the Waverley Line.
A five span rounded arch railway bridge was built over the Whiteadder Water, in the hamlet of Chirnsidebridge, in 1863 to carry the railway.
