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.
History of the North British Railway (until 1855)
The engineer Miller proceeded with building the main line. He designed the Dunglass Viaduct, near Cockburnspath. It had six arches; the main span was 135 feet, 111 feet high, approached by three and two respectively of 30 feet each. Stations were basic, reflecting the skimping of the budget, and this included the Edinburgh station. The Edinburgh and Glasgow Railway was extending its line from Haymarket to a joint Edinburgh station which was to be called "North Bridge". The station was being built by the Edinburgh and Glasgow Railway and it was not ready until 3 August 1846. The line was laid with 70 lb per yard rails in 12 feet lengths
