New York has a second nickname,“ the city that never sleeps”, an insomnia metropolis in perpetual motion. Like the city, the subway never rests. It runs 24 hours a day, 7 days a week. It's the fastest way to get around. Average speed on asphalt 10 kilometers per hour. Average speed on rails, 48 kilometers per hour.
纽约有着第二个绰号，那就是“不眠的城市”,这个好动的大都市也有着失眠的一面。像城市一样,地铁也从不休息。它一天24小时运行,一周7天。这是最便捷的交通方式。沥青上的平均速度是每小时10公里。铁轨上的平均速度是每小时48公里。
Conceived in the 19th century, it was the world's first subway with four track service, two local tracks, two express. No waiting. In a city chokes by congestion, the subway was a breakthrough.
成形于19th世纪,它是世界上第一个有四条线路的地铁,两条当地线路,两条高速路。不需要等待。在拥挤的城市中,地铁是一种突破，为人们带来了便利。
From a single line tentacles spread across the city to become the most extensive subway system on earth.
从单一横跨城市的线路成为地球上最广泛覆盖的地铁系统。
