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.
Edward Watkin
Watkin started his tunnel works with the South Eastern Railway in 1880–81. Digging began at Shakespeare Cliff between Folkestone and Dover and reached a length of . The project was highly controversial and fears grew of the tunnel being used as a route for a possible French invasion of Great Britain; notable opponents of the project were the War Office Scientific Committee, Lord Wolseley and Prince George, Duke of Cambridge; Queen Victoria reportedly found the tunnel scheme "objectionable". Watkin was skilled at public relations and attempted to garner political support for his project, inviting such high-profile guests as the Prince and Princess of Wales, Liberal Party Leader William Gladstone and the Archbishop of Canterbury to submarine champagne receptions in the tunnel. In spite of his attempts at winning support, his tunnel project was blocked by parliament and cancelled in the interests of national security. The original entrance to Watkin's tunnel works remains in the cliff face but is now closed for safety reasons.
