A railway line linking central China's Wuhan City to northern Shijiazhuang City will start construction soon as the middle section in completing a passenger-only rail line between Beijing and Guangzhou, China News Service reports.

The 838-kilometer railway connecting the other two sections already being built has a designated speed limit of 350 kilometers per hour and will cost 74.3 billion yuan, or about 9.89 billion U.S. dollars, the report says.

The high-speed passenger rail line, once completed in 2010, will shorten travel time from Guangzhou to Beijing to 12 hours and from Wuhan to Beijing to 6 hours.

A feasibility study on the railway section was finished on Thursday by the China International Engineering Consulting Corporation (CIECC), entrusted by the State Development and Reform Commission.
