Steam train crossing a high stone viaduct toward light

An atmospheric cinematic view from inside an old-fashioned passenger train, as if the viewer is looking out through a window along the length of the train in the direction of travel. A vintage steam locomotive is pulling a long line of old passenger carriages across a towering stone railway viaduct high above a dramatic mountain valley. Thick billowing clouds of dark steam and smoke rise from the locomotive's chimney and drift into the sky. The train has an unmistakably historic, 19th-century appearance, with elegant weathered carriages, brass details and a powerful black steam engine. The viaduct stretches across the vast valley toward a steep mountain on the opposite side. The railway continues directly into a tunnel carved into the mountainside. The tunnel entrance is not dark — instead, it radiates an intense, warm, ethereal golden-white light, almost otherworldly, illuminating the surrounding rocks and the approaching railway tracks. The train is moving toward this mysterious glowing tunnel. The composition emphasizes depth and perspective: the railway tracks and viaduct lead the eye toward the luminous tunnel in the distance, while the train's carriages curve subtly through the frame.
