Create a premium lock screen wallpaper for a modern iPhone using a generic modern iPhone family fallback, in a tall 9:19.5 portrait ratio with a target production canvas of 1290 × 2796 px. Recompose the source image into a true upright vertical coastal railway scene while preserving its visual identity: a vintage green electric train passing through a seaside level crossing, warm cream window frames, yellow-and-black crossing signals, slender utility poles and overhead wires, a calm blue ocean in the distance, and towering sunlit clouds beneath a clear cyan sky.
Use a cinematic low street-level perspective with the train placed across the lower-middle of the frame and the coastal horizon visible behind it. Let the railway poles, crossing equipment, and overhead lines create elegant vertical and diagonal structure without overwhelming the scene. Keep the upper 25–30% spacious, softly graded, and mostly filled with open blue sky and gentle cloud forms for the clock, widgets, status indicators, and Dynamic Island area. Keep the clearest train detail below center, preserve clean edges around the carriage roof and crossing signal, and simplify the bottom gesture zone into quiet road texture and soft shadow.
Render the scene as refined nostalgic coastal photography with subtle stylized realism, warm late-afternoon sunlight, clean architectural detail, softly reflective train windows, calm ocean color, and luminous cloud volume. Use sea blue, turquoise, jade green, warm cream, sunlit yellow, pale cyan, soft gray, and restrained golden highlights. Preserve the quiet seaside railway atmosphere, sense of travel, and gentle everyday charm while removing all readable signage, branding, route numbers, advertisements, and incidental lettering. Use smooth sky gradients, balanced OLED contrast, clean shadow detail, controlled highlights, and crisp local separation around the train without excessive sharpening. The final result should feel serene, cinematic, nostalgic, coastal, and immediately usable as an iPhone lock screen wallpaper.
Avoid: sideways or rotated composition, landscape monitor framing, desktop wallpaper layout, text, captions, route numbers, readable signs, logos, brand marks, advertisements, watermarks, UI overlays, phone mockups, clutter in the upper clock zone, important details under the Dynamic Island, dense wires behind the clock, cropped train body, malformed carriage geometry, bent rails, distorted wheels, duplicated poles, duplicated signals, extra trains, extra vehicles, crowds, visible faces as focal subjects, chaotic street clutter, harsh midday lighting, storm clouds, muddy greens, oversaturated cyan, blown cloud highlights, noisy shadows, color banding, low-resolution textures, extreme sharpening, fake tilt-shift blur, unrealistic ocean placement, broken perspective, or any composition that reduces lock-screen readability.
