Congratulations on this wonderful purchase! I'm glad you were able to locate and buy a set that has such incredible value to it. I guarantee you shall be very proud of it once you build the thing and set it up.
However, you should keep in mind that the 9V system uses track with electric rails for power, hence why the wheels have those metal rims. Therefore, this will not run on your Power Functions (non-metal) track unless you use foil tape on the plastic rails. It is interesting how this copy includes extra track parts that wouldn't normally be there. If I ever bought LEGO trains, I would've started with a 9V set.
