3D Printed On30 Ore Cars, 2 each, pre drilled for trucks and couplers. Raw, may require cleaning and sanding. Bare bodies ready to clean, paint and detail. Does not include trucks, couplers or details. Color may vary.  I use HO Scale Accurail Andrews trucks with 33" intermountain wheelsets, and Kadee couplers with Kadee gearboxes, and 2/56 screws for all. The trucks will thread right in, but you will need to drill for the couple boxes, starter holes are present on the print to assist you in starting the drill bit. This combination should present you with very little height adjustments required to obtain the correct coupler height. Cars may come in various colors, but mainly beige, gray, black.
