Is there a simple way to create a Part Two (Chapter 2...3, etc) to a scenario. That is, a second part to a scenario from where the first scenario left off. Can this be done without re-seting cars, motive power and idle cars on sidings. In other words everything remains the same and in the same position as when the first scenario left off.
I would hate to replace all things in the new scenario from the old.
My thanks for any help.
