My daughter bought me a copy of MSTS for Christmas in 2001. Six months later I purchased a "19 Diesel Add On" for MSTS at a local computer store. While loading it into my computer, I checked on the back of the box to see to see if any steam locos were available.
The web site was Auran.com. I didn't find any steam locos, but I discovered Trainz, and downloaded a video showing how to construct a layout in Surveyor. I was so impressed that I immediately ordered a copy.
It arrived the first week of September 2002, and needless to say, it far exceeded my expectations. Since then, I've been continuously involved with Trainz, and I can say that I've never gotten bored with the hobby.
