China Railway Construction Corp said yesterday that it had won contracts worth 6.23 billion yuan for a rail project in East China, the latest mega order the company has won this year from the country's frantic rail building boom.

The country's second biggest railway and expressway builder said its subsidiaries have won an order to build part of a passenger-only express rail between Shanghai and Hangzhou, capital city of East China's Zhejiang province.

The value of the contracts is equivalent to 3.51 percent of the company's 2007 revenue under the Chinese accounting standards, the Shanghai-listed builder said in a stock exchange filing.
