The Subway of New York and Shanghai. Yesterday, I learned an article which is discussing the difference between subway system of New York and Shanghai, and its intention is subway system of Shanghai is superior to New York's on many aspects, such as convenience, punctually, environment and safety etc, especially the platform screen doors. These are true indeed, because these two subway belong to the totally different time.The first New York City metro was put into use by the public in October 27, 1904, and has been used for more than 100 years and is one of the earliest subway in the world. And Shanghai Metro was built in 1993, and now becomes the largest underground public transportation and the most modern administrative system recently, for example, punctuality rate is up to 99.8%, the way buying ticket is by scanning or app, even paying with faces in the future. This is just a story of elders and younger and latter surpassed the former.
