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.
Eastern Counties Railway
There were no additions to the ECR network in 1850 and in 1851 a short branch from what is now Shepreth Branch Junction near Shelford to Shepreth was built. Back in 1848 Parliament granted authority to the Royston and Hitchin Railway to extend their line from Royston. Although Cambridge was its goal, Parliament sanctioned only an extension as far as Shepreth (as the Eastern Counties Railway had opposed the extension to Cambridge). The line was completed in 1851 and initially the GNR, who had leased the Royston and Hitchin Railway in the interim, ran a connecting horse-drawn omnibus service. This proved unsuccessful so the new line and the line to Hitchin were leased to the Eastern Counties Railway for 14 years, with a connection at Shepreth to enable the ECR to run trains from Cambridge to Hitchin.
