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.
Epping to Chatswood rail link
There have been proposals for a railway between Sydney's North Shore and the Main Northern lines since September 1920, when John Bradfield's plans were put forward for a railway between St Leonards and Eastwood. The proposed route was via the present Parklands Avenue in Lane Cove to the head of Burns Bay, across the Lane Cove River near the present-day public school at North Ryde, and terminated about north of Eastwood station. After political moves, and potential engineering difficulties with hills south of Eastwood station in the 1930s, the terminus was changed to Epping, where the line became known as the "Epping-St Leonards Railway". To this end, the State Government resumed several of the estate houses in Epping around the present-day Brigg and Albuera Roads for a track to loop the line into the main line and terminate the trains at Epping. When voters in neighbouring Eastwood then complained, the line was proposed to link south of Eastwood, use island platforms at Eastwood and then link to Epping.
