G'day from Australia. I would like to make a suggestion. As the name suggests Train Sim World I would like to suggest trying to get some Australian Trains for the simulator. Such as the Kuranda Scenic Railway, Cairns, The Ghan, Indian Pacific, and the Great Southern. Just to name a few I think it would be awesome to see some Australian trains in Train Sim World 2.
Kuranda might be possible (either the Scenic Railway or the Savannahlander), but the Ghan/IP/Great Southern are _way_ too long for TSW
In Western Australia (AWST Time), the whole Mandurah Line can be made. Has a unique feature it's the railway line using a motorway Central Reservation (UK Australia terminology for a US Canada Median)
I think the Ghan and Indian Pacific would have far too few services (only 2 per week). It would be cool to see though it have a service if we ever got the Blue Mountains line or something. But my guess is it would be too much development effort for just a couple of services.
