Order has been restored at Kunming train station in southwest China's Yunnan Province where a deadly terrorist attack on Saturday night left 29 civilians dead and more than 130 injured.

Train arrivals resumed on Sunday after three trains with 3,000 passengers bound for Kunming, capital of Yunnan, were affected on Saturday night, said station officials.

Meanwhile, 60,000 passengers are expected to leave the station on Sunday, higher than the 59,000 on Saturday.

Part of a major road in front of the railway station is still under traffic control and a waiting area on a square east of the station is cordoned off.

With a heavy police presence, normal operations have resumed and passengers can walk into and out of the station with no new restrictions.

Security screening of passengers and luggage is being carried out and staff are maintaining order in more crowded areas.

In a ticket hall, people were seen queuing to buy train tickets. Some chatted with each other while others were playing cards.

"I was a little frightened when I learned about the attack in the morning," said Liu Yujiao, a college freshman who was leaving for the city of Qujing in Yunnan.

"But now I am no longer worried, with the heavy security presence," Liu told Xinhua.

Separately, the city's education authorities said all local middle and primary schools will have classes as normal on Monday, but they ordered more security in and out of campuses to safeguard the safety of teachers and students.

School officials will be on duty before and after class and police officers will be patrolling school campuses and surrounding areas.
