TOKYO ― Japan Freight Railway suspended all cargo train operations on Wednesday after the company found evidence of misconduct in safety tests, public broadcaster NHK reported.The suspension by the biggest cargo train company in Japan led to at least a daylong delay in parcel delivery services, according to courier operators, while the full extent of the impact on the country's logistics remains unclear.
Japan's transport ministry asked the company to conduct emergency checks on all cargo cars to ensure the safety of wheels. JR Freight decided on Wednesday to keep all of its cars out of action until their safety is confirmed, according to NHK.JR Freight did not immediately respond to a request for comment.The company aims to resume operations by the end of Wednesday and minimize the logistical impact by increasing the payload of each cargo car, Kyodo news agency later reported.
