An unforgettable memory of passengers traveling to Alishan in those early days was when the train went into a tunnel. "The moment they heard the toot of the whistle, everyone would get up to shut the windows; otherwise smoke from the steam engine's coal fires would blacken their faces in the unventilated tunnel!"
「火車過山洞」是早年去過阿里山的人難忘的回憶，「只要聽到『嘟』一聲，所有人立刻起身關窗，否則在不通風的山洞裡，蒸汽火車的燒煤黑煙會把人燻成半邊黑臉！」
