Caballos galopando en tren vintage con arcoíris

13-second cinematic video, smooth 24fps, inside a luxurious vintage train carriage with polished brass trim, warm golden lighting, and a red velvet seat. Static camera fixed to the train interior, looking out a large window as the train speeds forward. Outside, a vast lush green countryside meadow rushes past with heavy horizontal motion blur on grass, white fence posts, and tracks. A herd of 12–15 realistic horses (chestnut brown, black, white, and golden bay) gallops powerfully alongside the train from left to right, muscles flexing, manes and tails flowing in the wind, staying parallel to the window in perfect sync with the train’s movement. In the background: rolling green hills, distant mountains, bright blue sky with dramatic fluffy white clouds, and a vivid full rainbow arching across the entire scene. Warm golden sunlight pours through the window creating realistic lens flares, light streaks, and rainbow reflections on the glass and brass interior. On the left wall inside the carriage, a vintage Japanese travel poster with text '大地の旅' is visible. Soft, emotional solo piano music plays throughout. Dreamy yet hyper-detailed photorealistic style, warm color grading, slight natural train vibration, high contrast, cinematic depth of field, 16:9 aspect ratio, emotionally uplifting and serene atmosphere.
