解釋
二級品鋼軌-
Then, with another whistle, he began to move forward ; the train increased its speed, and soon its rapidity became frightful ; a prolonged screech issued from the locomotive ; the piston worked up and down twenty strokes to the second. they perceived that the whole train, rushing on at the rate of a hundred miles an hour, hardly bore upon the rails at all
它不斷加快速度，一會兒，速度已經大到了十分可怕的程度，車上只能聽見機車發出的一陣隆隆聲，活塞每秒鐘進返二十次，車軸在機油盒裡冒著濃煙，簡直可以說整個火車就象以每小時一百英里的速度在前進，鐵軌所負擔的重量減少了，因為高速抵銷了重量。
