Cinematic Miniature Railway Construction on Alpine Viaduct

Create a cinematic ultra-realistic miniature railway construction scene on a massive stone viaduct in a breathtaking alpine mountain landscape. Start with a wide establishing shot of an elegant stone railway bridge spanning a deep rocky valley with a beautiful waterfall, pine forests, and snow-capped mountains in the background. Show giant human hands carefully constructing a tiny railway bridge, placing individual dark-gray stone blocks one by one into a detailed stone arch. Transition into close-up macro shots of the hands arranging miniature cobblestones and using small tools to refine the railway track and bridge surface. Show a hand brushing dust and debris away from the miniature railway tracks with a small brush, revealing highly detailed metal rails, wooden sleepers, and realistic stonework. Finally, reveal a small vintage steam locomotive smoothly traveling across the completed stone viaduct, releasing soft white steam as it passes through the spectacular mountain scenery. Style: photorealistic miniature diorama, macro cinematography, extreme detail, realistic hands, natural textures, cinematic depth of field, soft morning sunlight, atmospheric mountains, realistic steam, smooth camera movements, shallow depth of field, 4K, highly detailed, satisfying craftsmanship, seamless transitions, vertical 9:16.
