I finished the basic structure for the two trains and the small pieces for the city. I still need to work forward of those basic structures. Also, I decided to use wire represents the pathway under the two trains. In order to make it floating in the sky. There will be two buildings/towers connecting the trains. And small squares for the city then reflect the train are on top of the city. I will have to put color on it, but I have not decided what color should I use for them.
