A sleek modern train gliding smoothly through vast green landscapes — surrounded by towering mountains, rivers sparkling in the sunlight, and fields of wildflowers swaying in the wind. The camera follows from above as the train curves gracefully along the track beside a crystal-clear lake reflecting the sky. Birds fly alongside it, and sunlight filters through clouds onto the train’s polished surface. Steam rises gently from its engines as it passes through forests of tall pines and open meadows. The sound of nature blends with the soft hum of the train — a perfect balance of technology and environment. Style: ultra-detailed 8K realism, cinematic natural lighting, peaceful mood, golden hour atmosphere, realistic motion blur, no fantasy or mystical elements — just pure nature and beauty.
