Retirement cakes for my dad's boss who worked for BNSF for over 40 years. The trains are all cake. Marshmallow fondant and buttercream icing. The chocolate cake in the background was an afterthought, as I was panicking about there not being enough cake. The trains are on a whole sheet cake, the chocolate one is 1/2 sheet. There was also enough Famous Dave's catered to feed an Army.
