Dubai Metro, United Arab Emirates

- 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.
- Blue Line: 47 kilometres (29 mi) Dubai International Airport to Al Maktoum International Airport, along Emirates Road.. This was originally proposed for construction starting along with the Purple Line and completion in 2012. Due to the recession it was taken under reconsideration and the RTA have fixed a deadline of 2014 for completion of this line.
- Yellow Line: Announced in April 2008
- Red Line Extension: 15.5 km and six new stations, terminating at the border with Abu Dhabi. No dates for completion announced.
