This 1986 Overland Models, Inc. model was imported and built by Ajin Precision Mfg. in Korea. The original box has only minimal shelf wear and comes with spare and detail parts. The SD40X was an experimental testbed for EMD, using the new 645 series prime mover, the 16 - 645E3, built on an SD35 frame. This particular model represents Union Pacific No. 3040 and has flared radiators like the SD45. It's beautifully painted in UP's Armor Yellow and Harbor Mist Gray, with glazing on the windows and lenses in the lights. It showcases the excellent build quality of Ajin's earlier runs. Note that this is a tank drive model.
