Train Roof Gunfight — Speeding Locomotive Duel

Vertigo western short, 10 seconds, 16:9. Sunset on a speeding steam locomotive: coal smoke whipping back along the cars, the boiler glowing, trestle bridges flashing past below. 0-3 seconds: the low tracking shot skimming the car roofs — a marshal in a dust-caked duster and an outlaw in a black hat trading shots atop the swaying cars, muzzle flashes strobing, the smoke streaming horizontally, the train's sway rolling both men with practiced balance. 3-6 seconds: the exchange — the marshal diving behind the wood tender as splinters burst, the outlaw advancing along the roof's spine, both firing; the outlaw's hat shot clean off in slow motion, spinning into the smoke, his hair whipping as he keeps coming, unfazed. 6-10 seconds: the trestle — the train thundering onto a high bridge, the gorge falling away on both sides, the duel continuing over the void; the final shot holds the two figures silhouetted against the molten sunset, gunsmoke and coal smoke merging, the train racing on. A signal gantry flashes past inches above their heads; the outlaw's lost hat tumbles along the roof, and the marshal kicks it aside without breaking his draw. Craft: steam locomotive with glowing boiler, wood tender, car roofs; marshal's duster, outlaw's black hat. Camera: low roof-skimming tracking, slow-motion hat shot, trestle wide. Lighting: molten sunset, backlit coal smoke, boiler glow. Atmosphere: vertiginous, mythic, deafening. Style: epic western action, 35mm anamorphic, smoke volumetrics, saturated sunset grade, 24fps.
