Meanwhile I was weathering 2 more freight cars. A UNION PACIFIC Boxcar with alot of graffiti and streaks and a 4 bay Chessie System centerflow hopper with dark rust allover. First the boxcar....

 It looks like there is a problem with the floor of this one. It doesn't stand parallel with the rails. Maybe a correction with plasticard will fix it.

 The graffiti is custom made with paints, small tip pens and decals also.

Inspiration on this one the following photo. I don't mean to copy exactly the prototypes rather than create something that looks the same and right considering the scale.
