The earthworks alone reportedly increased two-and-a-half times from 2 million cubic metres to 5 million. CRCC was seeking, with Chinese government support, extra compensation from the Saudi Arabian government to help cover the losses. Rolling stock On 4 April 2009, CNR Changchun (now CRRC Changchun Railway Vehicles) was awarded a contract to supply 17 Type A 12-car metro trainsets.

Knorr-Bremse supplied the braking systems with modifications to suit sandy conditions. It also features 5 train doors per side.
