I built and upgraded a Great Northern (GN) stock car kit.  I built the Accurail GN  stock single deck stock car in GN class SM that I numbered 55756.  The Accurail kit is a excellent match for GN prototype.  Upgrade includes carving off molded on parts, adding wire grab irons & ladder rungs, etc.  If you are interested in the build of  Great Northern stock car 55756, photos and write up of the build process including painting mineral red, lettering from various sources and weathering are now available on my blog I have to share photos and information of modeling projects on my Minneapolis & Northland Railroad Company.  If you would like to take a look please do at the following link:
