The country's railway authority is investing 50 billion yuan (US$6 billion) for a new round of railway construction in the Yangtze River Delta area to upgrade the existing railway network, according to Shanghai's railway authority.
Liu Lianqing, director of Shanghai Railway Administration, said this round of construction is the largest in the region's history in terms of investment volume and the number of projects involved. 
The upgraded system will shorten the ride from Shanghai to Hefei, capital of East China's Anhui Province, from seven hours to three hours, and the trip to Wuhan, capital of central China's Hubei Province, will take just 5 hours, or 12 hours shorter.
Currently, the administration has over 10 projects under construction, Liu said.  The Shanghai South Railway Station, with a total construction area of 600,000 square meters, is expected to be finished at the end of this year, while the construction of six super bridges and adjoining facilities has started for the first railway line in Shanghai's Pudong area.
Another key project of this railway upgrade is the construction of an electric train line linking Shanghai and Hangzhou, capital of Zhejiang Province.  Running 202 kilometers, the first electric railway in the Yangtze River Delta area is a major part of the country's backbone railway network.
