Ultra-detailed fantasy landscape of a vintage steam train traveling high above the clouds at sunset. A long, curved railway stretches across the sky, surrounded by dense, fluffy clouds in shades of blue, white, and soft gold. The steam locomotive is dark metallic with a glowing warm headlight and billowing thick black smoke trailing behind. The train cars are maroon and streamlined, following the curved track into the distance. The sky is dramatic and cinematic, filled with massive illuminated clouds reflecting golden sunset light. The overall artwork style is hyper-realistic, painterly, and atmospheric, with deep contrast, soft lighting, and a dreamy surreal mood.
