日本新干线（shinkansen） Shinkansen japan: [origin of Shinkansen] After the two World War, the second half of 50s, Japans rapid economic recovery, significantly speeding up the pace of development, and the business and circulation of the Keihin, Chukyo, especially in the developed area has become the Hanshin locomotive drive the entire Japanese economy. Connecting these areas Tokaido railway line in Japan accounted for 3% of the total length of railway, but take 24% of the total national passenger traffic and freight transport volume 23%, and the annual growth rate higher than the national average, transport capacity has reached the limit. At that time, the Japanese economy has begun the transition from the Renaissance to high growth, to promote economic development, achieve rich target, strengthen the connection of the three industrial zone and the surrounding areas Tokaido railway has become an urgent need. To this end, the Ministry of transport was set up in 1957 by the experts of the Japanese state railway survey , discusses how to enhance the transport capacity of the Tokaido railway line problem. In December 1958, the Japanese cabinet approved a plan to build the Tokaido shinkansen. Japanese National Railway Survey was put forward three options: one is to have the original narrow gauge railway line line of double track again; two is laying a new line of narrow gauge; three is the new line construction of the standard gauge. After careful study, to maximize the Tokaido railway line speed up, became the standard rail behoove chose to build the new route. Specifically, there are a number of reasons: one, compared with the original narrow gauge, standard gauge can run large vehicles, ensure transport capacity can be expanded; two, the laying of the new route, through widening the curve radius to set the high-speed train, thus to shorten the maximum time to reach three, the standard of construction; the new rail route can be greatly reduced by the urban part of the city,
