Wow...It is an amazing idea..
Joker is a lovely character in the world, everyone, especially the kids are always attracted by them with balloon! One day, one idea come out, why not make a train with joker as the theme ? After referred to mass paper work related with joker, clown, we got some ideas, such as, the main colors might be red /yellow/blue/white...now we have to consider that how to mix these colors in a train? How to design the character of the locomotive and wagons? All wagons are the same design or better to make some different shapes? Who are our main customers? Kids below 3 or even up to 10?
