Travelers are expected to make 130 million trips by rail and 13 million by air during the National Day holiday travel rush, railway and civil aviation regulators said on Thursday.

It will be the year's longest public holiday - eight days - as the Mid-Autumn Festival happens to coincide with the National Day holiday this year, starting on Sunday.

The travel rush actually began on Thursday.

The railway system nationally will see an increase of 10 percent over last year, China Railway Corp said. The passenger peak is expected to be on Sunday, when 16 million trips will be made. On Thursday, the railway network was expected to see 7.5 million trips.

According to the Ministry of Transport, 560 million trips are expected to be made by road and 15.9 million by water.

More than 13 million trips are expected to be made by air, an increase of 14 percent, according to the Civil Aviation Administration of China. The number of daily flights is nearly 14,800.

Peaks are expected before, during and after the holiday - from Friday to Oct 9.

China's busiest airport, Beijing Capital International Airport, is expected to see 3.95 million trips during the rush, the airport said.

Its passenger peak will fall on Saturday.
