Chance of fault on Dubai Metro: One per four million kms

Dubai: The Dubai Metro, the world's longest driverless metro line, has a train fault rate of one per 4 million kilometres or one fault in one metro car every 800 thousand kilometres, a senior official at the Roads and Transport Authority (RTA) said. 

A train fault rate is the rate by which a train's operation is interrupted and services are disrupted. 

Mattar Al Tayer, Chairman of the Board and Executive Director of RTA, revealed the Dubai Metro's fault rate during a tour of the Control Centre and Trains Maintenance & Cleaning Workshop at the Jebel Ali Depot.

The fault rate is considered excellent when measured by the standards of modern trains' faults worldwide.

During the tour, Al Tayer was briefed by Adnan Al Hammadi, the CEO of Rail Agency, about the work mechanism adopted in Jebel Ali Metro depot, which spans 110 thousand square metres. Operation tests are carried out regularly in all the facilities of Jebel Ali Metro Depot.

"The Dubai Metro has three depots for maintaining and cleaning trains; two for the Red Line at Al Rashidiya and Jebel Ali, and one for the Green Line at Al Qusais. It also has two Metro Operation Control Centers; one at Jebel Ali (as a contingency control center), and the other is the Main Control Center at Al Rashidiya; which acts as a watchdog of the movement of trains throughout the day to ensure the safety of commuters," Al Hammadi said. 

The depot can house up to 40 trains, while a workshop carries out internal cleaning of 20 trains, and body washing of eight trains per day.
