Thanks so much for your help Zec. The new computer is up and running. The Southern Heritage locos have been extracted and installed. One thing that I find very annoying. I built the Turntable following Chuck Brites great write up. I got all my loco's on the stub tracks around the turntable and saved the game. The next morning the turntable was empty!. All the engines were back in the yard. How do you keep this from happening? The same thing occurs when I build a consist in the yards with the cars for a way freight. When I get ready to run the train when I turn on the computer, the cars are all scatted in the yard! I thought the one way system for building track was odd but these things are a bit strange. How do you run a railroad like this. I have rebuilt the six towns and two yards and I was hoping to get some of my model railroad operators into multiplayer with Trainz. Don Eisan
