Another Hanoi's urban rail system to be tested early next month

The trial can last for six weeks, Sytra said, adding that the work will be considered finished when all tests are passed.

Built at a total cost of 1.176 billion EUR, the project has a total length of 12.5km, comprising an 8.5km aerial track that will connect Nhon depot with Thu Le Zoo and a 4km-long underground track that will link Thu Le with the Hanoi Railway Station.

The 8.5-km section is expected to be put into operation by the end of 2022, while the remaining 4 km is scheduled to be completed in 2027.

This follows another, the Cat Linh - Ha Dong system, which was commissioned a year earlier.
