The Little-Used Siding

Wanting to suggest that the passing siding on the branch line is not used very often, I tried some weathering techniques I had read.

First, used India ink in alcohol or water but wasn't very effective:

There's a faint dark streak, but not very satisfying.

Mixed some maple and burnt sierra (or some sort of name like that) acrylic with water.  Didn't mix very well, but finally got something that could be painted on.  Then added some coarse ground foam, some ground up dead leaves (especially near the center of the pulpwood yard), an a little polyfiber on the track area.

Hard to see, but also put in some yellow-orange flowering "weeds".

Made a scrawny tree from grape twig, hair spray, and ground foam.  Seemed to fit the scene. 

Most of material was fixed with hair spray or diluted white glue.  Probably need a few bushes between tracks to go with scrawny tree!
