I've been wondering if there are any UP Big Boys that are a bit better detailed than the Auran built-in version. Also, are there any late-model challengers out there? And while I'm on the subject of UP steamers, has anyone been able to get Cowboy's 9000 class engines updated and into Trainz 2010/2012? I was able to one time long ago but have lost my copy of Trainz 2006. Has he been able to update them to the Trainz 12 standards or has this development not occurred yet?
