More Boxcar Weathering

I completed 3 more boxcars and have a few more in progress.  I've been trying different techniques to see what results I can achieve.  It's been fun so far, and my car collection is slowly evolving into a more realistic fleet.

This KCS received a fade coat, grime/rust mix on the lower half of the car with an airbrush, handpainted roof using burnt umber, graffiti decals, and reflector stripes.  The trucks were given a grime/rust mix with an airbrush.

The WC was given a generous fade, hand painted roof with burnt umber, and I used a make up sponge to add burnt umber on the sides of the car.

The CPAA was given a fade coat, burnt umber on the roof, burnt umber to the sides, and graffiti.
