Hi David, although there are no actual WA style hoppers in Trainz to my knowledge (like the well known 'Woolie Wheaties' WW class), there is the WOAX open wagon (a Paintshed reskin if I remember rightly), plus there is also the XO class hoppers in original ARG orange and black livery (with either woodchip or coal loads). I'll check CMP and post the KUIDs here for you.
EDIT: there are three versions of the XO class - with coal load; kuid2:60318:60006:1, with woodchip load; kuid2:60318:60004:1, and finally without load kuid2:50567:60667:1. The WOAX wagon is kuid:144681:100046. Note that all these are showing up with either warnings or as faulty in CMP for 2010.
Little bit off of subject... but, where can I find some good looking GM class locomotives? I am kind of taking a fondness for them, similar to F units here in USA... The built-in content is lacking on TS12.
Hi pdkoester. Yes, Auran included the GM1 class in original Commonwealth Railways livery in earlier versions of Trainz, but I guess it must have been removed in 2012. In any event, it should be easy enough to find on the DLS (like above I'll check CMP for you and post it's KUID here).
EDIT: the GM class units in Trainz which I know of are:
The Built in version was released by Auran in two liveries: Australian National green and gold: AN GM class kuid:-1:100013 and Commonwealth Railways maroon and silver kuid:523:1038, and two versions in ARG livery (Paintshed reskins): kuid:60697:102263 and kuid:83329:100100. There are probably more, but these are just some of the ones I have installed on my system which I found in CMP. Hopefully this has helped.
