I’ve been using Microsoft Train Sim for for a while and have most of the payware stuff for it. It’s fun but I really like Trainz 2006 with the payware HP-Trainz release of Marias Pass and the new line of VMD’s SD70ACe locos. It’s a hoot, plus I get to switch from my mainline train to a yard switcher to set up cars in one session. Custom cabs are sheduled to be created for the SD70ACes which will be nice too. World of Trainz locos are great too with nice cabs & startup sounds.
I use to dimiss Trainz as not being like MSTS but it is getting a lot better. Marias Pass on Trainz is so much more fun than the MSTS version!
I’ve been looking for the new version locally but with little success. Have to wait on Walmart to get it in. They mostly deal with MSTS. So that is all I have at the moment.
