Space stations Riyadh's futuristic metro system

During construction, it will be the world's biggest public transport project, employing tens of thousands of people, developers say. According to the High Commission for the Development of Arriyadh, all carriages will be air-conditioned and divided into first, family and single class. Buses and trains take a distant second to personal cars in Riyadh and according to FCC Construction only 2% of commuters in the Saudi Arabian capital take public transport. It's no surprise because gasoline is highly subsidized -- a gallon at the petrol pumps costs around $0.50. According to Bloomberg, the world's largest oil producer ranks only second to Venezuela for the world's cheapest gasoline. According to reports, the Saudi government is weighing up increasingly the cost of fuel to give public transport a boost.
