Apocalypse Express: Cinematic Train Outbreak Sequence

30-second cinematic train outbreak sequence. Character A's face, identity, hair, and outfit match the reference throughout. 0–3s: Character A sits feverish and pale as the train enters a tunnel. Darkness swallows the windows; cabin lights flicker, then cut out, leaving only phone screens. Her breathing becomes ragged. 3–7s: Complete darkness. A wet tearing sound and muffled gasp break the silence. Emergency lights briefly strobe, revealing fleeting movement between seats. A scream erupts. Passengers panic and search with phone flashlights, catching fragments of struggling figures. 7–11s: The flashlight briefly reveals Character A with a darkened mouth and chin, eyes wide and unnatural. The train exits the tunnel; lights flicker back on, revealing a passenger clutching a bloody neck as dark veins rapidly spread across his skin. 11–14s: The bitten passenger convulses violently, veins branching and skin darkening. His bloodshot eyes snap open; he becomes fully infected and lunges at another passenger. 14–19s: Full chaos. Passengers scramble over seats and luggage toward the connecting door. Another bitten passenger transforms within seconds and attacks. Survivors slam the connecting door shut and barricade it as infected hands claw through the gap. 19–22s: Close-up of infected faces pressing against the door window as cracks spread. A terrified passenger grabs a fire extinguisher and blasts the infected through the opening, filling the frame with white spray. 22–26s: The train approaches another tunnel; lights flicker, threatening another blackout, but remain on. Survivors catch their breath amid blood and overturned luggage, then barricade themselves inside the next car as the sealed door shudders under pounding. 26–30s: Close-up of a survivor nervously watching the approaching tunnel. Cut to a wide exterior shot of the train speeding through the night, windows flickering between light and darkness as it approaches another tunnel. Unresolved cinematic outbreak dread.
