A key coal railway linking China's Shanxi and Shandong provinces began 20 days of maintenance on Sunday, with trains suspended for three hours daily to support the work.

The maintenance work will run till March 28.

"During the 20-day maintenance period, more than 20 large machines will be deployed. At the same time, we will address tunnel damages and carry out repairs and maintenance on equipment, including the signal and catenary systems of the railway," said Jia Xinwen, director with the dispatch and command center of the Linfen section of China Railway Taiyuan Bureau Group Co.
