The Dubai Metro is a rapid transit rail network in the city of Dubai, United Arab Emirates. The Red Line and Green Line are operational, with one more line being constructed. These first two lines run underground in the city centre and on elevated viaducts elsewhere. All trains are fully automated and driverless, and, together with stations, are air conditioned with platform edge doors. Architecture firm Aedas designed the metro's 45 stations, two depots and operational control centers. The Al Ghurair Investment group were the metro's builders.
