To really know what makes a great city work, you have to peel back its skin and expose its secret life force. A system of incredible complexity and technology, the millions depend on but few understand. A fantastic voyage now begins, a journey deep inside the world's megacities-- they call it the Big Apple, the largest metropolis in America.
Eight million people scatter across five boroughs, each a city in itself. The core of the Big Apple, the bustling borough of Manhattan. Like no place on earth, New York is famed for its pace, yet life here would slow to a crawl without one vital piece of infrastructure, perhaps the most famous transportation system in the world——the New York Subway.
It's the engine to drive this megacity. Seventy five percent of New Yorkers have no car, they don't need one, New York has the best transit system in America, yet the subway is a system under siege. Daily it faces a triple threat, from man, from nature and from time. Count the perils and mind reels. Two thirds of the subway runs under ground, under roads ,under rivers, under skyscrapers, the system truly carries the weight of the city on its shoulders-billions of tons of concrete and steel, asphalt and earth all bearing down. Millions of liters of water threatening to flood in. 100-year-old network struggling to keep up and the most ominous number of all, 9-11. In these dark shadows, the specter of terrorism is no illusion; it's a nightmare, New York survived, and struggles daily to never relive.
这是驱动这个大都市的引擎。百分之七十五的纽约市民没有汽车,他们根本不需要,纽约有着美国最好的交通系统,但是地铁是一种遭到恶评的系统。每天都面临着一个三重威胁,从人来的,从自然及时间的。三分之二的地铁是在地面下,道路下,河流下,摩天大楼下。地铁系统真正在肩上扛起了这个城市数十亿吨的混凝土和钢筋、沥青及所有的土壤。数百万公升的洪水涌入。100岁的网络系统疲于应付,最坏的号码就是9-11。在这些挥之不去的阴影中,恐怖主义的幽灵没有幻影;它是一个噩梦。纽约存活了下来,在自己的日常生活中无休止的挣扎着。
