China Shenhua Energy Co , the world's most valuable coal producer, said it will invest 13.5 billion yuan ($2.03 billion) into the building of a railway.

Shenhua will finance 35 percent of the investment using its own capital and the rest through bank lending, the firm said in a statement to the Shanghai Stock Exchange.

Once completed, the railway will have annual capacity of 200 million tons. The project is expected to be completed by 2012. (Reuters)
