A vintage steam locomotive painted in dark tones with red accents, traveling through a snow-covered landscape at night. Thick white smoke billows from its chimney as it moves along tracks surrounded by frosty vegetation and snow-covered ground. In the background, a grand fairy-tale castle with numerous spires and turrets glows warmly against a mountainous backdrop. The sky is dark and starry, enhancing the magical, cinematic atmosphere. Snowflakes gently fall throughout the scene. The composition is vertical and centered, optimized for mobile wallpaper.
