A biker wearing desert goggles and a sand-colored jacket races a dirt bike alongside a speeding freight train in a vast Sahara landscape. At the 2-second mark he hits a dune ramp and launches toward the train roof. The bike lands across the top of a container car while sandstorms swirl around the convoy. Camera tracks low along the train as the rider speeds across multiple cars before jumping toward the locomotive. Golden desert sunset, high-speed train rooftop ride, dune launch stunt, cinematic sand particles, 4K.
