The Dubai Metro is a driverless, fully automated metro network in the United Arab Emirates city of Dubai. The Red Line is partly operational, the Green Line is still under construction, and further lines are planned. These first two lines run underground in the city centre and on elevated viaducts elsewhere. All trains and stations are air conditioned with platform edge doors to make this possible.

The first section of the Red Line, covering 10 stations, was ceremonially inaugurated at 9:09:09 PM on September 9, 2009 by Mohammed bin Rashid Al Maktoum, Ruler of Dubai, with the line opening to the public at 6 AM on September 10.

Once the 20km Green line opens in June 2010, the Dubai Metro will overtake the title of longest automated metro network from the Vancouver Skytrain, surpassing it by 3km.
