Here is the answer to the long asked question as to how I weather my track.
I weather my track with Poly Scale paint and it is in their Military color line. It only comes in the 1/2oz. bottles and is called Imperial Japanese Army
Brown (FS 30108)505276)
I airbrush the rails sides with it and then wipe the rail head before the paint dries. I use a piece of cardboard behind each rail as I am spraying the rails sides. I also airbrush the ties with RR tie brown also made by Poly Scale. Once the paint has dried. I go back and give a wash with watered down grimy black here & there to vary the color a bit. I also use Bragdon's weathering powders and use a dark gray or black and dust the ties in the center between the rails to give a grungy/ dirty look to some areas. Here is the finished look. Thanks for looking!
