Eastern "Big Ugly's" My Next Weathering Victims

I'm an equal opportunity model railroader, and believe that all rollingstock no matter what age, color, condition, etc. can find a place in my fleet.  Even those "eastern" roads are interesting models, and add a lot of character to a train when mixed in with BNSF and UP equipment.  I have a nice selection of CSX and NS 86' boxcars that I chose for my next weathering victims.  Here I have started on a unique and rare grey NS version.  It received a fade coat followed by chalks.  I used burnt sienna oil on the roof.  It will get some graffiti, reflector stripes, and maybe a dusting around the bottom of the car with an airbrush to finish it off.
