The Nhon-Hanoi Station metro line, the second line of the Hanoi metro, hit an operational efficiency rate of 99.65 percent during its first seven-day test run, according to the Hanoi Metropolitan Railway Management Board.

The test run, which began on December 5, was conducted in two phases, with the first designed to evaluate the line’s Reliability, Availability, Maintainability, and Safety (RAMS).

The second phase of the test run was conducted on December 13 and 14, right after the RAMS evaluation was completed, during which several safety hazard scenarios were simulated, such as blackouts and fires.

The Nhon-Hanoi Railway Station metro line, the second route to be put into operation in the capital city after Cat Linh-Ha Dong, will run 12.5 kilometers from Nhon in Nam Tu Liem District to the Hanoi Railway Station in the downtown area.

It will include 8.5 kilometers on elevated tracks and four kilometers underground upon completion.

Each of the eight trains is designed to carry between 944 and 1,124 passengers.

The metro route is anticipated to help reduce 20,000 metric tons of vehicle exhaust in Hanoi each year. 

Construction began in 2010 at an estimated cost of EUR783 million (US$832.6 million), which was then revised up to EUR1.1 billion ($1.17 billion) in 2014 and is mainly funded by official development assistance (ODA) from France.

It was originally expected to be finished in 2018, however, the overall progress of the project was estimated at just 75 percent, with the elevated section at 96.3 percent, this past August, according to news site VnExpress.

Its first train was put on a trial run in January last year.

After many delays, Hanoi has set a target for the commercial operation of the elevated section by the end of this year, and the whole route in 2027, VnExpress reported, anticipating that the first deadline will likely be missed.
