Okay, here goes. I am wanting to take a railroad I built in Railroad Tycoon, and recreate it in Trainz 12. I know I am looking at maybe years worth of work. I guess what I am really asking is it even possible to build something this large in Trainz. The Great Lakes, Mississippi Valley, & Gulf of Mexico starts in Mobile, AL goes thru Montgomery, Birmingham, where it splits to Memphis, Tn and Huntsville, AL. From Memphis to runs along the Mississippi River to St. Louis, MO, then turns north east to Springfield, Il and Chicago. the line going to Huntsville, Al continues on thru Nashville, Louisville, Indianapolis, Gary, and rejoins the western main at Chicago. From there it ran on to Milwaukee, Green Bay, and ends at Ste. Saint Marie, MI. That comes out to around 2200 plus or minus miles depending which side of the split at Chicago and Birmingham. Or should I just work on smaller sections and not try and make one huge route.
