This 3D model restores the classic DF7C shunting diesel locomotive widely used in China's railway yards, adopting iconic bright red body with white V-shaped decorative stripes. The front end is printed with China Railway logo and vehicle number DF7C 5082, with worn and faded texture to simulate long-term field operation wear.
The car body is equipped with heat dissipation shutter windows on both sides, bilateral walkway metal guardrails and access ladders. The bottom part completely reproduces double bogie wheel sets, coil spring suspension braking system and end coupler buffer device, matched with standard concrete sleeper railway track.
