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.
Waverley Route
In the state in which it was acquired, the E&DR was of little use to the NBR as it had been operated as a horse-drawn tramway for the previous thirteen years, was built to a 4 ft 6 in gauge and was in a dilapidated state in terms of both infrastructure and rolling stock. Nevertheless, the concern brought with it a number of advantages: its proprietors had developed an efficient coal-marketing organisation which would greatly benefit its new owners, it consolidated the NBR's position in Edinburgh while also barring the rival Caledonian Railway from the Lothian Coalfields, and, perhaps most importantly, the E&DR pointed in the direction of Carlisle. Parliamentary authorisation for the line's acquisition was obtained on 21 July 1845 with the passing of the North British Railway (Edinburgh & Dalkeith Purchase) Act, which allowed the NBR to lay a spur from its Edinburgh-Berwick line near Portobello to the E&DR at Niddrie, thereby allowing NBR services to run directly from North Bridge station to Dalhousie.
