As was typical in areas near railroad tracks in the 1950s, there are several recycled freight cars on the layout, including tank cars. I use these recycled tank cars as the focal point of various mini-scenes.
All of the tank cars were purchased at swap meets for a few dollars or less and then weathered as one might expect for a recycled car. Weathering consisted of dry-brushed paints, weathering powders and washes made from diluted paints and alcohol/weathering powder solutions.
The one heavily rusted tank car (below) was an experiment in which I spread a layer of glue on the car body and then sprinkled on rottenstone. I then coated the surface with rust colored weathering powder.
Rottenstone is weathered limestone mixed with various forms of silica. Also known as "tripoli", it is a fine powdered porous rock used as a polishing abrasive for metal and wood finishing. It has applications similar to pumice.
As used on this tank car body the rust effect is extreme and maybe a bit overdone.
Details were added to complete the scenes. I have boxes of detail parts so there always a lot of choices to for finishing each mini-scene.
Below are photos of these mini-scenes.
