A silver passenger train crosses a narrow bridge inside a vast frozen canyon. A hairline fracture races through the glacier wall beside it, faster than the train.

00:00:05.000 --> 00:00:10.000
Inside the front cabin, the engineer sees chunks of ice falling onto the tracks. He pushes the control lever forward while passengers turn toward a growing thunder behind them. The camera vibrates with the rails.

00:00:10.000 --> 00:00:13.000
Low side angle. The bridge begins collapsing section by section as the train accelerates. Ice blocks explode against steel supports and fill the air with crystalline dust.

00:00:13.000 --> 00:00:15.000
The final carriage clears the bridge by inches. The camera remains behind as the entire crossing disappears into the blue abyss, leaving only drifting snow and silence.
