Chinese authorities are cracking down on disruptive passenger behavior that causes high-speed train delays, after video surfaced online of a woman, who deliberately stopped her train from leaving on time. Natalie Pang has the story.

A short video clip of a female passenger preventing a high-speed train door from closing has sparked controversy online.

Luo Haili, a primary school teacher in east China's Anhui Province, wanted to keep the door open for her husband, who was running late. The woman refused to move, despite the train conductor's orders. Her actions caused the train to depart four-minutes late. Since then, Luo Haili has been fined around 300 US dollars and suspended from her job. But she is not the first person to delay a high-speed train.

Another female passenger in northwest China's Shaanxi Province recently tried to delay her train, after fighting with her husband. A passenger in Nanjing, in east China's Jiangsu Province, told the police to tell train staff to wait for him for 20 minutes because he was running late, forcing his fellow travellers to waste valuable time. For the railway station, it's like domino effect.

JIANG MING, DEPUTY CHIEF ENGINEER CRSC DESIGN INSTITUTE "High speed trains coming from multiple routes will interact at the hub. Because of this interaction, one high speed railway's delay will spread to other high-speed railways, and influence the entire high speed railway network."

A five-minute delay may lead to the adjustment of an entire train network, and disrupt the operation of many trains. According to Chinese law, those who illegally obstruct trains, ships, planes or other modes of transport may face warnings or fines under 30 US dollars. In severe circumstances, violators can receive five to 10 days detention and heavier penalties. One thing travellers should always remember "don't be late. time waits for no one." Natalie Pang, CGTN.
