Dubai Metro, United Arab Emirates

Lines
When completed, Dubai Metro will have 70 kilometres (43 mi) of lines, and 47 stations (including nine underground stations). Two lines are under construction, and three more are planned. The Roads and Transport Authority's masterplan includes 320 km of metro lines up to 2020 to cater to the expected 3.3 million population of the city. There are plans for 268 km of light rail tracks to act as a feeder system for the Metro. The fate of this entire network – which would reportedly be divided into Yellow, Orange, Magenta and Black lines – is now dependent on an economic recovery and private investment.
