Congratulations on the creation of such excellent images.
I have been holding back on purchase of Railworks 3 as there does not appear to be any Australian content. Being a user of MSTS since its inception I have emassed a vast array of routes and models which have been created by very talented and dedicated people both past and present. Their efforts are very much appreciated every time I create an activity and drive an Aussie route. It will be a real shame to have to leave all this wonderful content behind.
It is unfortunate that interest in MSTS seems to have almost dissapeared, I guess the fact that it is over eleven years old means that it is considered to be past it's use by date.
Open Rails shows great promise and once the developers get to a stable revision I am sure that interest will return and many great Routes and rolling stock will be created using the extra features that Open Rails will provide.
Unfortunately, I do not have the talent to be able to create Aussie content for Railworks 3 and feel very envious of your efforts.
I wish you great success with your Aussie content for Railworks 3 as this sofware is superior to MSTS and it looks like there is an active group that will continue to improve it's performance.
I look forward to following your progress.
