Christmas Island is a 135 sq km island in the Indian Ocean, not far from Indonesia, which was a British territory until 1957 and has been Australian since then. It has a population of about 2,000. The main economic activity used to be phosphate mining and an 18-km standard gauge railway from Flying Fish Cove to the phosphate mine was constructed in 1914. It was closed in December 1987 when the Australian government closed the mine. More on the line and its equipment is on this webpage.
