Re: Defence sites study
There is a railway on Rottnest Island
An entry states in part
"A light railway was built from the jetty at Kingstown Barracks on Thomson Bay, to transport materiel and munitions to the guns. Captain (later Brigadier) Frank Bertram Hussey (1908–1985) was seconded from the Australian Staff Corps to oversee the construction of this. The military fixtures including the barracks and railway became known as the "Rottnest Island Fortress".
"After World War II the guns and infrastructure were decommissioned and parts of the railway removed. The 9.2-inch battery, however, was saved from disposal because the high cost of removing and shipping the guns to the mainland exceeded their value as scrap metal.
In the 1990s the gun emplacements and railway were extensively reconstructed, and since then a popular tourist activity has included a tour of the guns and the tunnels, with the journey to the battery being made on a purpose-built train from Kingstown Barracks. In November 2003 a new railcar was put into service for this route, called the Captain Hussey (named after Brigadier Hussey; see above). The railcar was built with volunteer assistance, and cost $171,500."
