Railway Minister Sheng Guangzu says trains designed to run at 220 miles (350 kilometers) per hour will slow to 190 miles (300 kilometers) per hour, while those built for 155 miles (250 kilometers) per hour will be cut to 125 miles (200 kilometers) per hour. State media quoted him as saying Wednesday that those designed for lower speeds will also be slowed.

The reduction in the highest speed had previously been announced, but the additional cuts suggest greater concern about safety following the July 23 crash between two bullet trains that killed 40 people. The government also said it is conducting further systemwide inspections.
