Tomica World--Amtrak Super Spiral

I had received some boxes of my nephew's old trains and track from my sister in law a while back.  She thought that my youngest son might be interested in trains.  Since he really hasn't shown any interest, I decided to dig through the boxes to see what was in there.  I found the instruction manual for a few things and one of them was for the Amtrak Super Spiral track.  I tried to research some because I wanted to see what things went with the set in case I wanted to build it or trade/sell it.  From the research I found, it appears to be pretty rare.  I am trying to figure out what pieces I have, but so many of the blue pieces are so similar with some minor changes in what year/words are found on them.  I just wanted to see if you guys could tell me what to look for to know what actually belongs to this set and what doesn't.  I know there are some Tomy Thomas sets included too, so that's why there are different dates on the pieces.  Here is a picture of the instructions and the Amtrak train (I am assuming) goes with it.  Thanks for any help/information you can give.
