BEIJING — China has been speeding up the resumption of major railway construction with a total of 115 under-construction projects nationwide having fully resumed work, the China State Railway (CSR) Group Co Ltd said.

In April, fixed-asset investment (FAI) in national railway projects came in at 67.8 billion yuan (about $9.54 billion), surging 10.9 percent from the same period last year and having nearly doubled from March.
