On my last layout which was from 2002 to 2013 I had a California Department of Forestry fire station which I built from a Rix Products kit. If I had taken any photos of it on that layout I can't find them now. When researching things for this layout I found that the fire station in Carlin was of a similar design but with an extra door. Since I still had the old model, I decided to use it again on this layout but with some upgrades.
One of the things I wanted to be able to do with this structure was to pose each of the doors either as opened or closed. The solution I came up with was to use Velcro on the back of each door and on the inside of the roof of the building to store the doors when they are open. The fit of the doors into the wall is snug enough that they don't need any glue to stay in place.
The building sits on a removable base that has blocking of styrene strips around the inside of the walls that hold the building in place. The building can be easily picked up to change the position of the doors or move around the fire engine models.
Some of the details added were rain downspouts made of .035 styrene rod added at each corner of the building and some signs that were made on the computer and printed on paper. I only have a couple of fire engines right now representing different eras but plan to add more in the future. As the layout is modeled in different eras from the mid 1970's to mid 1990's I plan to have at least 2 set of fire equipment that can reflect those different eras.
