Inspired by John Le’s brine car, I thought I wanted to build one, too. I like unusual cars.
First came research. Then I found an “enclosed tank car” used to haul brine, wine, etc.
Heinz ran a small fleet of 40’ enclosed tank cars. They basically had the three or four vats inside, with access thru top hatches. This way, I wouldn’t have to worry about building the vats.
I also deviated from the exact model as to bracing and signage.
My example is a 40’ brine tank car in 1:20.3. Decals by Stan Cederleaf. Riding on PNG Andrews trucks with PNG, Ozark and homemade hardware.
