My Train Baby Shower Cake

I was given an invitation for inspiration. This cake is nearly 4 ft long. The duck cake and car are banana cake with caramel espresso buttercream filling. The present cakes and car are apple spice cake with cinnamon buttercream filling. In the teddy bear car, the teddy bear is rkt, and the cake is vanilla with fudge filling. The train engine part is fudge cake with vanilla buttercream and ganache filling. The entire cake is covered with white chocolate fondant.
