Use the supplied image as the first frame, preserving the vast mountain landscape, curved stone viaduct, red steam train, and golden sunrise. The locomotive steadily moves forward away from the lower-left foreground, following the rails toward the distant bend near the center of the image. Its carriages follow smoothly along the same curve, maintaining consistent spacing. Rhythmic puffs of white steam rise from the chimney, expand, and trail backward over the carriages. The surrounding sea of clouds slowly billows between the mountain peaks and around the bridge pillars, revealing and concealing small sections of the landscape. Sunlight gently filters through the drifting vapor. Hold a stable aerial wide shot so the train’s progress is clearly visible within the immense scenery. Natural real-time motion, no time-lapse. Sound: distant rhythmic steam-engine chuffs, soft wheel clatter, and airy mountain wind. No cuts, dialogue, or music.
