CSX Transportation #335, a GE AC4400CW. These heavy-haulers are the workhorses of the East Coast, often pulling coal or intermodal freight through the Philly corridor. A masterclass in textures. The weathered blue paint against the rusted orange structural beams uses a "complementary color" scheme (orange and blue) that naturally draws the eye. The tight crop on the number "335" turns a piece of machinery into a graphic art piece.
