At approximately 11:45 AM on February 25, a metro train traveling from Yen Nghia to Cat Linh abruptly stopped at Lang Station.

After nearly 20 minutes of troubleshooting, operations resumed, and affected passengers were issued ticket refunds.

Technical error causes brief disruption

A representative from Hanoi Metro Co., Ltd. (Hanoi Metro) explained that the stoppage was due to a switching track failure at Cat Linh Station. This issue required a temporary power cut to ensure operational safety.

"After 10 minutes of troubleshooting, the entire system was back in operation. This was a routine incident in metro operations, and we sincerely apologize for any inconvenience caused to passengers," the Hanoi Metro representative stated.

This is not the first time the Cat Linh - Ha Dong metro has encountered such issues. On December 7, 2021, a similar situation occurred when a signal failure at Cat Linh Station forced a train heading from Yen Nghia to return to La Thanh Station.

At that time, Hanoi Metro also refunded tickets and arranged bus transportation for affected passengers. However, officials later clarified that the incident was a simulation exercise rather than an actual failure.

Previous incidents on Hanoi’s metro system

The Nhon - Hanoi Station metro line has also faced operational issues. On October 24, 2024, at 5:24 PM, a metro train traveling along the elevated section between Nhon and Cau Giay suddenly stopped due to a power failure affecting multiple stations, including Le Duc Tho, Vietnam National University, Chua Ha, and Cau Giay.

The disruption caused Train 04 to halt between Vietnam National University Station and Le Duc Tho Station. Hanoi Metro's operations control center immediately notified relevant units and worked to resolve the situation.

Hanoi Metro has assured the public that all such incidents are managed according to 57 pre-established emergency response scenarios.
