China has approved construction of four railway lines worth 66.24 billion yuan (10.79 billion U.S. dollars) as the government steps up infrastructure investment to boost growth.

It is the third time this month that China approved new railway projects. 

China plans to operate 7,000 kilometers of new railway lines this year. However, only about 32 percent was in use as of October.
