远远望去,未来的机车运行起来犹如在高架上飞速滑行的雪橇。它趋近导轨,而导轨却高出地面23英尺,它几乎没有任何识别标志:既无发动机,又没有车轮,更没有钢轨。使所有人尤感惊奇的是,它没有普通机车运行时发出的喀哒声、隆隆声和呼啸声;随着机车飞驶而过,只能听到它以每小时300英里速度划破空气的声音。 From afar, the future locomotives will behave as if they were sledding on a high-speed sledge. It approaches the rails and the rails are 23 feet above the ground. It has almost no identification: no engine, no wheels, no rails. To everyone’s great surprise, it does not have the clicks, rumblings, and whistling that would occur when an ordinary locomotive was running; as the locomotive flew over it could only hear it breaking through the air at a speed of 300 miles per hour. sound.
