The Dubai Metro is the flagship Project of the Roads and Transport Authority
(RTA) Dubai
Design and build contract was awarded to Dubai Rail Link (DURL) consortium in
2005
Largest driverless fully automated metro network in the world
Dubai Metro is the world's second most affordable metro transportation system
Since 09/09/09 launch, over 178 million people have travelled reliably and safely
Dubai Metro, a flagship for the region

Challenges during Construction & Operation
The system size was itself a big challenge for construction
First metro project in the Arabian Peninsula region. The expertise and technology was not available
The harsh environmental conditions such as extreme heat, high humidity, sand etc.
The large and complex interfaces between the ATC system and many other subsystems
Amount of automation (fully automated depot, train wash, control of stabling shed doors etc.)
A tight project schedule to meet the 09/09/09 date
Coordination between large multi-national, multi-lingual and multi-cultural workforce
Planning for the proper working & traffic control in the most congested areas
Suitable alignment interface with road projects
Ridership pattern was difficult to guess and different user’s behaviours
Operator was involved later
Operation procedures were paramount in degraded mode (i.e. Train time out )

LESSONS LEARNT
Concession with world class consortium, operator & ISA
Time bound review of technical specifications / technologies
Nurturing a unique work culture among multinational workforce
Good Public/passenger education/awareness due to first metro in the region
Close monitoring at all stages of work
Communication & marketing strategy
Identification & early resolution of critical and important issues
Enthusiastic staff with diverse railway backgrounds
ATC system went through rigorous testing following a comprehensive test plan
Involvement of the operator during the system operation demonstration period
Presence of experts from system supplier in OCC during initial launch period
Safe management of the outstanding works and configuration change management during operation
Track markers have been provided to support manual train driving in exception case
Mock drill and test case on failure scenario, proper and fast recovery procedure

Future Challenges for Signalling in Middle East
Interoperability between different signalling system & different onboard equipment
Connectivity between Main Line railway network (Etihad railway) & Metro network
Performance of signalling system in terms of capacity and in terms of traffic management
Tough environment conditions due to high heat and dust
Remote condition monitoring is required
Energy saving initiatives & green CBTC
Improved robustness against EMI/EMC/Noise issues
Extension of asset lifecycle and reductions in asset life-cycle costing
Equipment obsolescence
Presence of suppliers of Metro Railway signalling systems in region
Transfer of technology and self-dependence in Metro signalling System
Education, research and development facilities about modern signalling systems
Lack of Metro signalling skilled people and experts.
