My 4 yr old grandson is obsessed with trains, especially Thomas. Since his birthday is in my busiest cake month, he rarely gets a nice cake so this is his Birthday cake this year. I can’t wait to see his face. I baked a chocolate cake, using egg whites to make it denser, and I baked it in a large loaf pan so I could carve it. The round part was baked in an aluminum drink can. It is all covered in MMF. There will be a couple of train cars added too.
