The first batch of grain hopper is now officially weathered. Many techniques were used, including oil and acrylic paints, washes, fading, color modulation, chalks, color pencils and weathering powders.
All cars were weathered according to prototype pictures circa 2006-2008 and graffiti were hand drawn using color pencils.
Most cars are a mix of old Athearn Blue Box kits, Accurail and Intermountain. The weathering was intended to blend together the cars, thus narrowing the huge difference in detailing.
Another batch of hoppers is ready to meet its fate. At the end of the day, about 25 cars will have to be weathered. As a starting point, I'm doing the rib-sided cars first, keeping the smooth-sided ones for later.
