Train cake

If I had had more time, or the marshmallows that I thought I had actually be in the cabinet, I would have made a really cute little track made of Rice Krispie treats to put the cake on PRIOR to making the train. But life does not always go as planned, so I kinda scribbled the track on the sheet with icing after the cake was placed. I live by the "I wish I had done this"'s when I make my cakes. This was for my nephews 5th birthday, and he has a slight obsession with trains.
