According to the Railway Network Planning for the period 2021-2030, with a vision to 2050, the two high-speed railway lines are both related to Quang Ninh.
These are the Hai Phong - Ha Long - Mong Cai railway line with a length of 187km, investment roadmap until 2030 and after 2030; the Hanoi - Quang Ninh high-speed railway line with a length of 124km, of which the section passing through Quang Ninh province is over 40km long, designed speed of about 350km/h, investment roadmap until 2030.
Previously, in July 2025, Vingroup Corporation proposed to invest in the construction of the Hanoi - Quang Ninh railway line, designed speed of 350 km/h, exploiting passenger ships, with a road length of 1,435 mm. Regarding the route, the enterprise proposed that the route from Co Loa station take the road connecting to Gia Binh airport, through Hai Phong to Yen Tu, Quang Ninh province. After that, the railway line continues to the forest park area, Tuan Chau ward, Quang Ninh province and connects to the Hai Phong - Ha Long - Mong Cai railway line. The project investment is about 5.4 billion USD.
To more effectively exploit the Hanoi - Ha Long - Mong Cai high-speed railway system, Quang Ninh province is researching and developing an infrastructure system connecting to the above railway line.
The orientation is to develop an infrastructure system connecting the Hanoi - Ha Long - Mong Cai railway line with Van Don Special Zone, Con Ong - Hon Net Port (old Cam Pha City), Yen Tu and Tuan Chau areas.
According to information from the People's Committee of Quang Ninh province, for the Hai Phong - Ha Long - Mong Cai railway line, Quang Ninh province has reported to the Prime Minister to use the provincial budget to implement the following items, such as: Investment preparation, detailed planning, project clearance for the entire route and branch line connecting to Con Ong - Hon Net seaport. Along with that, invest in the construction of the Hai Phong - Ha Long section in the 2026-2030 period and continue to study investment forms to invest in the Ha Long - Mong Cai section before 2030.
For the Hanoi - Quang Ninh high-speed railway line, the province is focusing on coordinating with specialized agencies of the Ministry of Construction to develop a detailed plan for the entire route.
