China's railways have recorded 123.663 million passenger trips since the summer travel season began on July 1, with hubs ramping up service to meet demand, according to China State Railway Group.

Passenger traffic is relatively concentrated in the Beijing-Tianjin-Hebei area, the Yangtze River Delta, the Greater Bay Area, and the Chengdu-Chongqing region.

The Chengdu Railway Bureau has already processed over 10 million passenger trips, which is a significant increase from last year. To handle the upcoming surge in demand, the bureau will add 11 pairs of overnight high-speed trains from Friday to Sunday, serving major cities across the north, south, central, northwest, and southwest of the country.
