All of them are Athearn blue box locomotives with a lot of moding and detailing including built from scratch non dynamic hoods on the GP9s, the damage/remains on the lead locomotive and all the grab irons are hand bent from brass rod stock, Details West parts for the pilot detailing. Everything is painted and weathered by hand with a brush, no air brush work and the snow effect was done with powdered white pastel applied with water and a matte clear coat seals all the weathering!
