HÀ NỘI — After five consecutive days of test runs, the Nhổn-Hà Nội Station metro line showed a feasibility rate of up to 99.65 per cent, according to the Hanoi Metropolitan Railway Management Board.

The trial runs, starting on December 5, was conducted in two phases, with the first lasting from five days to six weeks in order to evaluate the line's RAM efficiency.

If the efficiency recorded during the first five consecutive days failed to reach 98 per cent, the trial run will be extended until the goal is achieved, to the maximum of six weeks.

The second phase of the trial run was conducted on December 13 and 14 right after the RAM efficiency evaluation was completed, with several scenarios simulated, such as blackouts and fires.

The 12-kilometre Nhổn-Hà Nội Station metro line, the second of its kind in the capital city, starts from Nhổn in Nam Từ Liêm District and ends at the Hà Nội Station in Đống Đa District, and includes eight elevated and four underground stations.

Once fully operational, eight trains will be officially in service, with one used to ease overloading at peak hours.

Each train is designed to carry between 944 and 1,124 passengers. The trains are manufactured by France's Alstom company.

The project's investment of about VNĐ30.1 trillion (US$1.29 billion) comes from official development assistance of the French Development Agency and loans from the French Government.

The elevated section is slated for commercial operation by the end of this year, while the remaining part which is underground will be put into use next year. — VNS
