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.

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.
