I am a HO Model Railroader, have been for over 55 years. My hands do not work as well as they used to so I started to look for a Railroad Sim. I found Trainz 12 on line and decided to give it a try. I love this Sim and all it has to offer. I am very pleased with the ability to re-skin and build content for this Sim. I am a Steam guy who likes the 1920s and 30s and I like the variety of steam available. I look forward to the next generation of Trainz.
