The Riyadh Metro (Saudi Arabia) and specifically lines 4,5 and 6 built by the FAST consortium, has been the protagonist in the Arab News medium. With first-class functionality and innovative design, the new metro will have capacity for 3.6 million passengers daily. It is one of the largest metro projects in the world.

According to the Royal Commission of the city of Riyadh, the network will consist of six metro lines connecting 85 stations and covering some 176 kilometers. Traversing densely populated areas, the network will link King Khalid International Airport and King Abdullah Financial District, prominent universities, central Riyadh and the public transportation hub.

The project has incorporated several sustainable measures into the grid to reduce energy consumption, adopting a combination of energy generated on site from photovoltaic cells, energy efficient equipment, LED lighting fixtures and occupancy and presence sensors. Much thought has gone into water conservation and the project utilizes on-site treated greywater, wastewater effluent, water-saving fixtures and efficient irrigation systems along the metropolitan corridor.

Once completed, the project will significantly reduce carbon emissions by providing a sustainable means of transportation to facilitate vehicle mobility for citizens and residents.
