This was my first multiple tier cake with a hole through the middle. It was sculpted and covered in ganache then covered in white fondant and finally airbrushed to give as any rock effect. Each train was also made from white gumpaste, built, left to dry and then each airbrushed, one red and one blue. This was a christening cakes for two brothers, one was 3 and one 18 months and they wanted something abit more modern than the traditional train cake.
