(Engineering Daily) Reporter Nguyen Anh Duong = Vietnam's Hanoi subway has become visible.
The Hanoi subway line No. 1 project has been under way by China's six railway groups, but the project has been delayed far beyond the previous 2013 target of completion due to financial problems and other than the previous one.
