im making a scenario and all teh rolling stock i place is empty, hoppers containers, ect. how do i place them in the scenario already filled?

I don't believe you can. But once you place them, you can double click on them (or just click and pull up the flyaway to the right, and there will be a little picture of a load there and an empty check box. Check the box and the car will have a load.

Indeed, this is the method tada.

Doubleclick on a single car or to load/unload all cars in a consist doubleclick while pressign Ctrl.
A flyout appears on the right side of your screen. There is the option to load/unload teh car/ all cars.
