Create a hyperrealistic portrait of a man in a vintage train conductor or dispatcher uniform, inspired by early 20th-century railway aesthetics. The man has short dark hair, a well-groomed beard, and striking blue eyes. He wears a tailored, double-breasted coat with brass buttons, a formal tie, and a classic train conductor's cap, detailed with a golden railway insignia. The uniform should have subtle details, like gold buttons and trims, reflecting the prestige of the railway profession. The color palette should include neutral tones like gray, brown, and beige, with subtle blue accents for the eyes and gold for the uniform's buttons and insignia. Use soft lighting, realistic shadows, and lifelike textures to achieve a hyperrealistic, 3D digital art style. The image should evoke a classic, nostalgic atmosphere with highly detailed features, fabric textures, and natural light reflections, portraying the elegance and professionalism of early 20th-century train conductors.
