I have been in Model Railroading since I was 25. The current railroad was built in 1968. When we built this house I had a large extension added to the house with heat and air-conditioning. (Had to. Its in Dallas Tx.). I've been at this hobby for almost sixty years. After a back operation failed to fix the problem I was looking at the end of a wonderful hobby. I had seen the adds for trainz for a number of years and low and behold it now had multiplayer. Needless to say I've been busy the last four months rebuilding the layout on trainz. Town for town, industry for industry. (the buildings are not the same. I've had to tell my operators that I've run into problems and it will be another few months before the Southern Model Railroad comes back to life. 1. What is this business about having to build all double track and build each track the same way. One track left to right, the other right to left. Back in the 60's and 70's you had a lot of single track with passing sidings. How do you handle that? If I fail to get 6 LIVE operators I was planning on using AI for passenger or thru freight runs. Most of our sessions have mostly way freights out on the line, but the thru traffic keeps them on their toes. 2. How do you take a 74 square table top and reduce the width so that you join them north to south (or up & down) so you only have scenery near the tracks. 3. Why do loco's and sometime cars have "homing" habit. Locos back to turntable, cars to the yard. When you know that's not where they were last. I have a number of "I can't get it to work or add anymore signals but this is a start. Don Eisan (deisan)
