In this third part of my brief Auran Trainz review, I drive a Queensland Railways 2100 Class diesel on the built-in Queensland route. The scenario is actually the built-in "Intro" session, so it is one that anyone with Trainz 2009 can drive. There is another session available for download that allows the user to drive a more modern train with working cab signals, something the default Class 2100 doesn't include.
