Snowbound Semmering Viaduct Over Niederösterreich

Photorealistic, ultra-detailed winter scene of the historic Semmering Viaduct in Lower Austria (Niederösterreich). Snow blankets rugged alpine slopes and pine forests as the grand stone arches of the viaduct span a frosty gorge. Soft blue-hour light with a pale sun breaking through moody clouds; gentle snowfall drapes the scene in white. A vintage steam locomotive crosses the viaduct, smoke curling into crisp air, highlighting the UNESCO-era charm. Rich textures: weathered stone, powdery snow, frosted rails, mist in the valley. Cinematic, low-angle composition emphasizing the arches and leading lines into distance. Cool color palette with warm highlights on sunlit masonry; high-resolution, hyper-real detail, serene yet dramatic mood.
