Etheridge railway line
Although construction was delayed by strikes in mid-1908 over the pay rate for railway workers, in February 1909 the line was opened to Einasleigh from Almaden. The Einasleigh copper mine was originally discovered by Richard Daintree in the mid 1860s, but the cost of transporting ore from the site made it uneconomic and it soon closed. The location was lost until the 1890s and a renewed interest in copper on the Etheridge field. A township known as Copperfield was established on the banks of the Copperfield River to service 12 copper mining leases extant by 1899, and this was surveyed as Einasleigh in 1900. The mine was reopened that year by the Einasleigh Freehold Mining Company, in which John Moffat had acquired an interest. By 1901 copper matte from a smelter at Einasleigh was being transported to Almaden by camel train. The coming of the Etheridge Railway in 1909 allowed Einasleigh to boom, and it was the largest centre on the Etheridge between 1907 and 1910. By 1910 six ore trains a week were running from Einasleigh to the Chillagoe smelters, and in 1911 the mine was purchased by the Chillagoe Company. It closed in 1914, and was reopened by the Queensland Government between 1920 and 1922.
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.
