I use Auran Trainz myself. I'm running the 2004 version. I like it better than the current version. I build all my own models in Gmax. I've made a bunch of D&RGW equipment - K-37's, 36's, 27's, C-16's, C-21's, bunches of rolling stock, and RGS #20. But, my main focus has been on the RGS. I've got the route built from Ridgway to Durango. For buildings, I've got most of the Ridgway yard, Peake, and Brown. I'm working my way south. I've lettered the 455 and 461 for RGS. I'll be building K-28's soon I hope.
You can take a look at my models on my website: [
