China Railway Beijing Group Co said that it will have carried about 1.22 million passengers on Wednesday when the China's five-day Labor Day holiday ends.

On Tuesday, the company carried about 1.11 million passengers, 448,100 of whom started in Beijing.

The company is in charge of the railway lines of Beijing, Tianjin, Hebei and parts of Shandong, Henan and Shanxi provinces.

The Beijing transport authority said that as the holiday draws to a close, expressways with traffic heading into the city will be extra heavy from 4 pm to 8 pm as the number of returning travelers peaks. Railways and airports will see more passengers arriving from 10 pm to midnight.

Shuttle buses serving railway stations and airports will run longer to accommodate the passenger load.
