China's railway operator said Thursday the speed of Fuxing bullet trains running on the Beijing-Tianjin intercity rail will increase to 350 kph starting Aug. 8. 中国铁路总公司周四表示，往返北京-天津的复兴号城际动车从8月8日起将提速至350公里/小时。 Lu Dongfu, general manager of China Railway Corporation (CRC), made the remarks at a forum1 on smart high-speed rail development, marking the 10th anniversary of the Beijing-Tianjin line. Entirely2 designed and manufactured in China, the Fuxing, or Rejuvenation3, debuted4 on the Beijing-Shanghai line on June 26, 2017. The trains are more spacious5, reliable and energy-efficient and have a longer service life than previous models.
