It could be a model of a GP38-2 rebuilt from a GP40, like this BNSF unit from rrpictures.com. Photo credit: Joe Ferguson. That said, it appears to be a fantasy kitbash, as no rebuilt GP40s to my knowledge have a high short hood or the water tank for steam heat. http://www.rrpicturearchives.n...cture.aspx?id=573124
Edit: I found a drawing on Traniax.com of a NdeM high-hood GP38-2 with the correct fan spacing. These engines were apparently used in passenger service (per search results), so a steam generator would make sense. However, there is no indication of torpedo-boat style air tanks on the NdeM units; that appears to be a fantasy addition. Image credit: A youtube videotape.
