VicTrack Rail Reserves
The "VicTrack_Reserve" KML file provided at https://www.victrack.com.au/working-with-victrack/railmap should be loaded into Data.Vic and updated whenever VicTrack posts an updated version. (Ideally the data would be loaded into the Spatial DataMart, allowing it to be downloaded in more sensible formats than KML.) I just happened to find this data by accident - if it was in Data.Vic it would be easier for everyone to find.
It is also my understanding that VicTrack maintains a significant amount of other spatial data, including data relating to leases to the rail operators (i.e. which sections of rail reserve are leased to MTM, V/Line, ARTC, and tourist/heritage operators). Currently there is no VicTrack spatial data here on Data.Vic - it would be great to see some of their data being incorporated into Victoria's spatial data infrastructure.
