China's national railway network has increased freight capacity to transport more coal for power generation since last month to ensure the supply of energy for the winter and spring, the national railway operator said.

According to the China State Railway Group, the network transported 157 million metric tons of coal from Oct 1 to Monday, a year-on-year increase of 26.8 percent.

A total of 363 power plants that received coal supplies from the railway system stocked more coal last month than in September, the railway group said.
