Here are some pictures of the completed back of the station. I added a roof to the top of this section that will match the roof on the building. Since I am only working with a 14 inch building width, I layed out the front and side doors, windows and pillars as shown in the pictures. I went to AC Moore last night and found the pillars. They are used for weeding cakes and come in various heights. They were also pretty cheap. The windows I am using are a mix of Grandt Line and some Korber roundhouse windows.
It is very difficult for me to not try to construct something exactly how it looks. I spend many hours coming up with a plan and usually still not happy with it. Rather than drive myself too crazy, I just settle for what I think is best and hope the person I am building it for is happy.
