Dubai Metro, United Arab Emirates

Green Line: 20 kilometres (12 mi) line with 22 stations from Festival City, through the city centre, Dubai International Airport Terminal 2 and the Airport Free Zone. Originally slated to be 17 km, the line length was increased by 5 km to 22.5 km, and the opening date has been delayed from March 2010 to August 2011. As of October 2010, tracklaying was complete, and there had been a trial run.
Proposed
- Purple Line: 49 kilometres (30 mi) Dubai International Airport to Al Maktoum International Airport, along Al Khail Road. Construction commenced in March 2009 and be operational by 2012. It will have about eight stations on the route, three with check in facilities. However, The Dubai Airports claimed that this was unfeasible as it did not pass through many localities. They however suggested opting for a "central terminal" similar to ones in the US where trains leave from inside the airport to the other airport with trains also leaving to the city. The RTA have taken this into consideration.
