Can anyone clue me in as to the identity of this loco. http://www.railpictures.net/viewphoto.php?id=81510 It is listed as a SD40-2, but the "porch" on the back end looks MUCH larger than that of a Dash 2. If I'm right, I believe SD40-2s were built on the SD45 frame, thus the fact that is has the "porch" on the back. So is this a SD50 that was rebuilt to SD40-2 specs. maybe? Thanks for the help.
