.... I am pretty upset about this, on my old layout I had as a kid, I always had a freight train and a passenger train running together, and it was really neat.
You do know that you can run them together in ways that were impossible when you were a kid, right?
I hope I'm not teaching you to suck eggs here, "no offense intended", etc, but the "experts" will tell you that running two round in circles get's boring, fast - Now you can have a "prototypical" passenger train running, and the freight must get out of the way. The switcher(s) have to prepare the freight cars etc etc - You can "play" alone or with others.....
Don't be upset!
Cheers,
Ian
