This was a cake I did for a Retirement/Birthday, the guy worked for the train company for over 30 years and his invitation had pictures of these trains. He saw the evolution of the engine as you see them here. All the trains are made of yellow cake with buttercream and covered in fondant, the base of the cake is a yellow cake with buttercream frosting covered in fondant, I used my airbrush to color the base of the cake, the tracks are made from buttercream and the gravel is made of candy.
