Train Page for “Things That Go”

I am presently working on the quiet book page about trains.  This is the train track, tunnel and background for the page.  All I need now is to make the train.  Hmmm… that will need some more thought.My plan is to put part of the train through the tunnel on a length of narrow elastic cord much like the car on the car page.  I want the train to be more three dimensional though.
