列車飛速駛向隧道，雪崩席捲山間隘口；鏡頭從高空快速追拍

提示詞

超廣角空拍鏡頭從積雪山峰上方數英里處開始，接著迅速俯衝，朝駛入山隘的列車逼近。雪崩轟然崩落，沿著列車後方傾瀉而下，以一面流動的白色高牆填滿山谷。鏡頭沿著山脊滑行，與鐵軌平行，接著轉出一道寬廣的弧線，在列車飛速駛向隧道時，讓列車與雪崩都保持在畫面中。最後鏡頭迅速爬升，揭示雪崩如何吞沒隧道口後方的山隘。

Ultra-wide aerial begins miles above snowy peaks, then plunges into a fast dive toward a train entering a mountain pass. An avalanche breaks loose and pours down behind the train, filling the valley with a moving white wall. Camera skims along the ridgeline parallel to the tracks, then swings into a wide arc that keeps both the train and avalanche visible as the train races toward a tunnel. End with a rapid climb revealing the avalanche swallowing the pass behind the tunnel mouth.
