Excellent use of the art deco styling. I think the one on the bottom would be more likely to be used by companies because it seems to have a greater capacity. The upper one actually looks like an electric locomotive, very similar to the Pennsylvania Railroad GG-1 with the center section, and the nose almost seems to take influence from a Baldwin Shark.
you seems to have a lot of knowledge about trains etc... thanks for inside info, i didnt have an idea if there is something like this somewhere in the "real world". Are there any links with good quality pics of locomotives and trains?
Excellent steampunk exercise in style. Actually, the only weak point I can think of in this picture is that the frames are too big ^^. Other than that, the execution is great, your style is there, and the whole art is, well, very sexy.
