Riyadh Metro Development Project in Saudi Arabia

project in operation

The project involves developing the Riyadh Metro rail system in Saudi Arabia.The automated/driverless network consists of six lines and covers 176.5 km. It has 85 transit stations and seven rail depots. Of the 104.5 km of track, 20.9 km is in a bored tunnel, 3.2 km is in the cut-and-cover tunnel, 54.7 km is in a viaduct, and 25.7 km is at grade.The project has implemented multiple sustainable measures to decrease energy consumption, including using on-site photovoltaic cells to generate energy, energy-efficient equipment, LED lighting fixtures, and occupancy and presence sensors. In addition, there are efforts to reduce water use through on-site collected and treated gray water, treated sewage effluent, water-efficient fixtures, and efficient irrigation systems along the metro corridor.
