The fine was slapped against the 61-year-old owner by Hoan Kiem District police after he failed to show registration license and was found allowing customers to engage in activities that posed safety risks, Vietnam News Agency reported.
A video posted on June 18 that went viral on social media showed a woman rushing onto the track, believed to take photos of the approaching train, in Hoan Kiem District.
As the train nears, a man comes running to push the woman to safety. He was later identified as the cafe owner.
According to the district authorities, the woman's behavior was dangerous, threatening her life and railway safety.
Hanoi Train Street, known for its makeshift coffee shops along the train track, runs for around two kilometers from Le Duan Street through Tran Phu, Cua Dong and Phung Hung streets in the heart of the capital's Old Quarter.
Due to safety concerns, Hanoi authorities shut down the tourist attraction and set up barriers to prevent tourists from flocking to there in 2020.
Despite the ban and warning signs, many foreign tourists were still found visiting the Train Street and posing for photos at coffee shops along the tracks.
