Back to the original question of the thread starter....

Here is video with looking through Tarcoola Railway Station. It has some benches and what looks like a waiting room. It also looks as if there is a booking office window. More recent videos of Tarcoola station show that it has been re-roofed. Has anyone had a peek inside? I wonder if the manifests and timesheets are still strewn all over the floor? Was the layout of the TAR stations the same on the old Ghan route???

The above video highlights the argument that I have been making about repurposing the buildings. In some of the stops e.g. Hughes, Reid etc, the buildings look immaculate on the inside and the outside with new roofing. The vlogger goes inside one of them and it has a premium lick of paint. It looks quite habitable.

Any property can suffer vandalism, but nowadays, there is live and inexpensive CCTV. Most of the visitors would only ever get there by train and leave by train.... A permanent population in these towns, albeit small, would probably deter vandals.
