Train Station Carousel Toy

This is a rare Shelcore spin top train station carousel toy. My son (who is obsessed with trains) LOVES this toy. To make it go, you push the big red button down and the train goes spinning by and rings a bell. Although it is not that old, only a small amount of this toy was made.
