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 Union Railway
Victoria station was a terminus, and the Eastern Union wished to connect with the network controlled by the Eastern Counties Railway, to enable onward connections. The ECR had its own line from London to Norwich and did not regard the EUR as an ally, but a connecting line about a mile long was made to the ECR at Trowse Lower Junction, not far from the ECR Norwich terminus. At a gradient of 1 in 84 it was the steepest on the EUR system. It was used by special trains to Yarmouth races on 9 and 10 September 1851, although regular services did not start until 1 October. This was the last section of railway built by the EUR before takeover by the ECR. The hostility of the ECR was such that EUR locomotives were not permitted to enter ECR track; arriving trains for Thorpe station had to run round clear of the junction, and be propelled to that point for an ECR engine to couple and continue the journey.
