A section of a new high-speed rail line in central China collapsed following heavy rain, raising safety concerns after a train crash near China’s eastern city of Wenzhou killed 40 people last July, The Wall Street Journal reported. A 300-meter section of the Hanyi High-speed Railway in Hubei, which links the provincial capital Wuhan and Yichang city and is expected to open in May collapsed on Friday due to heavy rain. Hundreds of construction workers are working to repair the affected section, according state media. The extent of the collapse wasn’t immediately clear and there were no reports on any injuries. But Hou Xinyue, a local railway official in Qianjiang, argued that the incident affected 4.3 miles of the rail line, a larger stretch of track than reported by state media. The local rail bureau is said to be still investigating the accident.
