The Hanoi Department of Transport has just reported to the City People's Committee about the incident where the Nhon - Hanoi Railway Station metro line was forced to stop after an incident at Cau Giay Station on October 24.

Specifically, at 5:24 p.m. on October 24, there was a power outage in section 2 of Le Duc Tho station (station 5), National University (station 6), Chua Ha (station 7), Cau Giay (station 8), leading to the suspension of train operations until 6:15 p.m.

The Department of Transport said that at the time of the incident, the contractor contacted the operating unit but there was no staff on duty to access the technical room at Le Duc Tho station (where the incident could be resolved).

Therefore, the contractor's technical team had to travel from the depot to station 5, a distance of 5km, and it took 30 minutes to reach the technical room of station 5 to handle the problem. After that, the power outage was completely fixed at 6:00 p.m.

According to the contractor, the cause of the incident was a problem with the 220VAC - 110VDC power converter at the remote isolation switch cabinet (RIS3) at Cau Giay station. This was a temporary power converter because the underground construction had not been completed.

The incident caused the train to stop at Nhon, Cau Dien, and Cau Giay stations while the problem was being handled, delaying 6 trains and forcing the cancellation of 8 trains.

To ensure the safe operation of the route according to regulations, the Department of Transport recommends that the Hanoi People's Committee direct the Hanoi Railway One Member Co., Ltd. - the operating unit, to urgently recruit the missing personnel and ensure the capacity of the staff directly involved in the operation.

The company is also responsible for increasing on-site support forces, promptly coordinating with contractors and relevant units so that when an incident occurs, normal operations can be restored.
