[1] Union station opened on 9 September 2009 (09-09-09) as part of the initial stretch of the Dubai Metro, with Red Line trains running from Rashidiya to Nakheel Harbour and Tower.

As a result of its central location, nearby attractions and points of interest include numerous consulates, Dubai municipal government buildings, Al Ghurair City Mall and Maktoum Hospital.

[4] It is also close to Al Ghurair Centre, Dubai Creek, Twin Towers, and Union Square Bus Station[5] (with buses to Ajman, Fujairah, and Sharjah[6]).

Spanning 25,000 square metres (269,098 sq ft), it is the largest underground station in the world.

[3] Both lines utilise a side platform setup with two tracks each; the Green Line tracks approach the station from the west below Al Maktoum Road and turn northwards underneath Omar Bin Al Khattab Road, while the Red Line crosses Dubai Creek and travels below Omar Bin Al Khattab Road before turning sharply eastward underneath Al Rigga Road.
