A white Mitsubishi Fuso truck with rail wheels (a Hi-Rail Vehicle) is on a railway track, facing toward the viewer. The front of the truck shows signs of damage, with a deeply crumpled bumper and further damage and dents to the front panels. The truck's headlights are illuminated, and the windshield reflects the sky. The truck is on a track laid with gravel and wooden sleepers, and metal railings are visible on either side of the track. Lush green vegetation forms the backdrop.
