Create a cinematic 21:9 key visual for a coastal train journey at sunrise. Show the train curving along a cliffside track, with warm morning haze, layered distant hills, wet rails catching the light, and fine texture in the rock and vegetation. Keep the composition wide and calm, with the train as the visual anchor on the left third and open sky on the right. Add a restrained headline in clean white sans-serif type in the upper right: "COASTLINE EXPRESS". Keep the words correctly spelled, small relative to the frame, and well separated from the train. Natural lighting, believable materials, no distortion, no watermark.
