Dubai will soon have its metro/tram. The ABS consortium (Alstom, Besix and Sercoa), has signed with Dubai's Road and Transport Authorities (RTA) a 550 million dollars contract for the first phase of the tram that will connect Al Safooh to Dubai. Alstom will receive 300 million dollars for this phase. It will use an APS system (without catenary), which preserves the urban setting and fits in perfectly with the modernity of the city of Dubai.
