On the left is an absolutely incredible model of the Pennsylvania's electric passenger locomotive class "DD1" which was an unusual 4-4-0+0-4-4 or 2+B+B+2 arrangement.
The right has what has to be the most evocative photo taken of an electric locomotive, it being built, with its two IMMENSE traction motors hooked up to a jackshaft arrangement that drives 2 axles each. There's such a visually arresting aura of this imagine I haven't been able to shake since I first saw it as a teen. You could create a whole sci-fi world inspired by this image alone.
