Rolling stock
In October 2016, the first two metro trains were delivered, but services have not started yet. The line will be served by a fleet of 26 high capacity type A EMUs with a capacity of 2460 passengers per trainset.[9] Each set is 139.98 metres (459.3 ft) long, 3.09 metres (10.1 ft) wide and 3.8 metres (12 ft) high. The rolling stock is manufactured in Changchun by China's CRRC.[6][10] The train sets are developed to be able to withstand sand storms, and feature aluminium bodywork with sand resistant paint, sand resistant glass, and the ventilation system is designed to handle large amounts of dust in the air.[11][12]
