One is for The Ghan, a train that goes from South Australia to the Northern Territory and the other is a small steam train that travels the foreshore from Semaphore to Fort Glanville, in South Australia.
The Ghan is 2979km long and has a standard gauge of 1435mm (Wikipedia). The origins of the name are disputed, although both theories mention the Afghans, who once operated a successful camel train through the centre of Australia.
Semaphore Steam Train track is 2km long and has a 457mm gauge. That’s ten times smaller than The Ghan.
A popular tourist or family activity, particularly during the holidays, it runs along the foreshore, parallel to both the road and the tide and is a great sight, whether you are on it or viewing the people waving from open carriages.
Another perspective for Becky’s squares.
