The double-track line would be designed for 100km/h operation and would link Van Cao in the central district of Ba Dinh with Thach Binh in Thach That, with a journey time of around 30 minutes between the terminus stations. The line would serve new residential developments as well as the National Convention Centre, National Stadium, and the national administrative area.

According to local media reports, the cost of the project is expected to be around Dong 14.9 trillion ($US 2.87bn) and construction will be divided into two phases due to be completed in 2019 and 2024.
