According to a pre-feasibility study report for North-South high speed railway project, the total length of the railway is about 1,560 km, running along the North-South corridor, going through 20 localities, connecting Hanoi and Ho Chi Minh City. Of the total, the 14-km section in Hanoi shares the infrastructure with the Hanoi urban railway No. 1 (from Hanoi station to Ngoc Hoi station), and the remaining connects Ngoc Hoi station to Thu Thiem station, with 27 stations, five depots, and 42 infrastructure maintenance facilities. It is designed for passenger trains to run with a maximum speed of 350km/hour.
The first phase of the project has a total investment of 561.6 trillion VND (about 24.71 billion), while the second costs 772.6 trillion VND. The whole project is scheduled to be completed in 2050.
