In Nanjing, the local railway authority has put more tra

ains into service. It said residents in the city would likely make about 340,000 trips by train on Friday.

Other branches of the railway system have also launched more runs to handle the increase of holiday passengers.

Tomb Sweeping Day, also known as Qingming Festival, fell on Friday this year. It i

s a traditional Chinese day on which people pay tribute to deceased family members,

friends and national heroes. Chinese people have used the day for spring outings since ancient times.

In recent years, the number of Chinese travelers, to both domestic and foreign destinations, d

uring the Tomb Sweeping Day holiday has increased annually, and most of them travel by rail for some or all of the j

ourney. For destinations within China, railways offer lower prices and more choices than airlines.

At present, China operates more than 131,000 kilometers of tracks. That fig

ure includes more than 29,000 km of high-speed rail, two-thirds of the global total.

Last year, China invested more than 338 billion yuan ($50 billion) in the construct

ion of 26 new railways and opened new lines totaling 4,683 km, most of them high-speed.
