I too have been setting up my TRS2006 into routes that are continuous running sessions, all the way back to November 2006. I use iPortals in most cases but am in the process of building a complete division of CSX in southwestern Indiana. I use a group of Word documents in table form that emulates the car card system I have used in model railroading for years. All this is working fairly well and I use re-rail ports. However, as in real life, scenery and businesses change and are added, making such mods cause a complete restart of my operations or try to use Surveyor to set up the entire system as was at the time of the mod. The dynamic feature would as is stated here, make Trainz truly the best on the market and probably attract many more operators that stay away now because these sessions are like being in the movie 'Groundhog Day'!
I am glad to see that several operators are interested and have answered.
