Just finished today this Atlas O 40' boxcar for BN. Lately I have gotten into the scale and weathered look of cars, soon to be with Kadee couplers once the new layout is under construction. I did a simple fade with watered down white acrylics, airbrushed then dried with a hair dryer. I would say I have close to 15-17 cotes to get the light green look. The rest is done in powders and water based oils. Still learning ( No SIRT work here) but a good way to learn. If Allan Miller sees this he will recognize the little switcher. Nick
