Ho Chi Minh City (formerly Saigon)

Hanoi (Ha Noi)
planned metro, planned monorail, tram under construction

Though it has yet to break ground, Hanoi, with the help of Alstom and Japanese banks, is planning a 6 line, 92 km ful metro system worth $5.4 billion. As in other parts of Asia, the metro is referred to as a light rail line because just 3.9 km of the total 12.5 km starter line will be below ground. The line, known as "Line 3", 
is expected to begin construction in 2011 with an opening date of 2014.

A 32 km tram line in old Hanoi broke ground in 2011,
 Plans for a 38 km, 14 station monorail are also in the works.
