Serene Modern City Train Interior Travel Photo

Create a serene, premium travel photograph of the interior of a modern city train during daytime. Show a clean bright white carriage with large windows glowing with soft natural daylight, a row of empty blue-and-white molded seats along the window, with one distinctive orange seat standing out, stainless-steel vertical poles, overhead rails, and multiple triangular hanging hand straps in blue and orange. Use a slightly wide-angle documentary composition with strong leading lines, soft depth of field, airy high-key exposure, subtle reflections on the windows and metal, gentle pastel tones, realistic textures, understated film grain, calm minimalist atmosphere, authentic travel photography, sophisticated editorial aesthetic, natural imperfections, vertical 4:5 composition, no people, no logos, no watermark.
