Thorn lights first Gulf metro system
It took 49 months, 30,000 workers and £2.6 billion to build the first metro in the United Arab Emirates city of Dubai. It is 52 km (32 miles) in length, incorporates 29 stations and includes exclusive first-class compartments. The first stretch (Red line) opened in September 2009 and was followed by the Green line in September 2011. Another interesting feature of this transport system is that the trains are entirely unmanned.
Thorn Middle East had been involved from the beginning of the project and stepped up a gear once the award of the contract was given to ETASET.
By working with Atkins, the lead designer responsible for all civil works, and providing both lighting designs and visualisations Thorn was able to supply over 34,000 light fittings. Within the stations 35 different types of light fixtures were used, including over 12,000 downlights, 10,000 Micropak and 3,200 Arrowslim luminaires.
