哈囉~小朋友們!我是小艾姊姊!今天要來解答一個「轟隆轟隆」的問題唷~為什麼火車不像汽車一樣在馬路上跑,偏要在鐵軌上跑呢?

想像一下唷~火車就像一個超級超級重的鋼鐵巨人!如果讓它在普通馬路上跑,輪子會「噗啾」陷進泥土裡,像大象踩進軟軟的蛋糕一樣動不了啦!鐵軌呢?就是專門為巨人設計的「硬骨頭馬路」!兩條鋼鐵軌道把火車的重量分散開,讓輪子能「喀噠喀噠」輕鬆滾動~
~偷偷告訴你:火車輪子內側有凸凸的邊緣,像小手手緊緊抓住鐵軌,這樣轉彎時才不會「咻——」滑出去喔!還有還有!鐵軌像超長的方向盤,引導火車乖乖前進不迷路。如果沒有軌道,長長的火車可能會扭來扭去,像掉在地上的吸管一樣打結喔!下次看到火車,記得對鐵軌說聲「謝謝你當火車的專屬跑道」吧~
