Not 3D modeling at all just an image on my Model RR, and used GIMP to add smoke, I made the DD35, the other GP35's were painted, detailed, weathered by myself. A link to the DD35 build thread. http://www.frisco.org/shipit/index.php?threads/emd-demonstrators-dd35-gp35.6791/#post-52684 Thanks for the comment.
