  6. Violet line: Axis of Abdurrahman Bin Awf Road – Sheikh Hassan Bin Hussain Bin Ali Road, with a total length of 30 km.

Main stations

The Riyadh metro stations are designed according to a unified architectural pattern to give the project a unique identity. Intended to provide the passengers with safety and comfort, all stations will be air-conditioned, equipped with passenger information systems and provide internet access. Select stations will offer shops and car parks.

The Riyadh metro project includes four main stations located in highly populated areas and at the intersections of metro lines and the bus network. The stations provide support services such as parking lots, ticket outlets, shops, and customer service offices. The four main stations are as follows:

  • Qasr Al-Hukm District Station
  • King Abdullah Financial District (KAFD) Metro Station
  • Western Metro Station
  • STC Station

Metro cars

The trains are fully automated. All trains are uniformly designed, and are built for high passenger comfort and energy efficiency specifications.

  • 74 Inspiro sets for Lines 1 and 2, supplied by Siemens
  • 47 Innovia Metro 300 trains for Line 3, supplied by Bombardier
  • 69 Metropolis sets for Lines 4, 5 and 6, supplied by Alstom


Specifications of metro cars have included the world’s latest technologies. All metro cars share a uniform design, with colors following the color of their designated line. Passenger comfort has been a central element to all metro car producers.


Each train and station are equipped with advanced surveillance systems, firefighting equipment, tunnel safety systems, and sophisticated communications between network and the Operations & Control Center. The trains have been subjected to intense testing to ensure they can withstand the city’s harsh climatic conditions.


The metro cars are designed to be energy efficient, and some of the project’s facilities will make use of solar cells to help save the power required for air-conditioning and lightening.

Supporting infrastructure


21 park & ride locations with a capacity of 200-600 cars each, have been dedicated to facilitating the use of the metro network. The park & ride locations are well-distributed throughout the city to simplify commutes.

Safety and security

The metro network meets all safety and security requirements for passengers and facilities; all metro cars and stations will be provided with advanced security systems, which include CCTV-cameras and early warning systems, firefighting systems, tunnel safety systems and a communication system that supports real-time communication with the Control & Operation Center and security personnel.


The Riyadh Metro project includes the establishment of seven parking & maintenance centers, including workshops for regular maintenance, offices for the staff and parking areas for the metro train fleet, as well as control centers. Five advanced centers will operate, control, and monitor the metro lines, trains, stations, and other project facilities.

Riyadh Bus Project

The bus network is fully integrated with the metro network, connecting the districts of Riyadh with the business and commercial centers. With the capacity to transport over 500,000 passengers, the bus network will serve as a main means of transportation within residential districts. Providing comfortable and efficient transportation for all residents of Riyadh, the bus network will enhance city mobility and reduce traffic congestion and environmental impact from individual vehicles.

Once fully launched, the comprehensive bus network encompasses 2,860 stops and 80 routes, served by 842 buses.

  • Three Bus Rapid Transit (BRT) routes will provide 160 km of dedicated bus lanes serving high-capacity corridors, offering faster, more direct, and reliable journeys.
  • The 19 community lines (910 km of network) will link major attractions and services such as hospitals, universities, shopping malls, parks, and recreational centers, and will connect to BRT and Metro stations.
  • 58 feeder lines (835km of network) will provide seamless connections to the metro and BRT system.
  • There is a planned Demand Responsive Transit (DRT) service aimed to provide the link to the ‘first or last mile’ of a passenger’s journey in residential areas.

The bus network project includes four types of stations that match the different network levels in terms of design, capacity, and function. It also features a bus tracking system and a passenger guidance and information system which aims at increasing the efficiency of the network operation and providing the passengers with real time updates about their trip and bus schedules.


The brand-new Riyadh bus fleet consists of 842 buses, manufactured by Mercedes and MAN. By acquiring 600 Mercedes buses, the RCRC made the largest commercial vehicle procurement in the history of the vehicle manufacturer. The bus fleet is made up of three bus types:

  • 421 Mercedes Citaro G
  • 179 Mercedes Citaro
  • 242 MAN Lion’s City


The buses have a modern and sleek design. All buses are equipped with on-board Wi-Fi and a smart ticketing system. The buses are spacious and well-adapted to accommodate different passenger groups and are wheelchair accessible. All vehicles and bus stops are equipped with air-conditioning for a comfortable experience.


The Riyadh buses meet international safety standards. To secure the safety of our passengers, CCTV monitoring is installed on all buses and bus stops. Our driver performance monitoring system ensures that drivers hold the highest standards.


Running on ultra-low-sulfur fuel, the new Riyadh buses are the most environmentally friendly ever used in Saudi Arabia. The buses will help reduce CO2 emissions and traffic congestion in the city.

Supporting infrastructure


Four dedicated park & ride sites allow easy access to the bus network. Each parking site has a capacity of 200-600 cars. These are part of the 25 parking sites within the King Abdulaziz Project for Riyadh Public Transport, which covers both the bus and metro networks.

Bus depots

The Riyadh Bus Project has two bus depots, which include workshops for regular maintenance, staff offices and parking areas for the bus fleet.

Control Center

Located west of Princess Nourah Bint Abdulrahman University, an 80,000 m² Control and Operation Center will:

  • Control the operation of buses
  • Communicate with the drivers
  • Manage the passenger information system and tracking system
  • Ensure integration between the metro and bus networks
  • Manage the unified ticketing system
  • Monitor security and safety systems

Current Status of Bus Project

The first phase of the Riyadh Bus service was launched with a fleet of more than 340 buses serving passengers at 633 bus stations and stops, 15 routes with a total of 86 tracks.

The second stage of the “Riyadh Bus” service was also launched adding 223 more buses serving the vast Riyadh city neighborhoods, providing access to 500 bus stations and stops covering 9 extra routes, including the extension of Line 11, dedicated bus lane service, as part of the overall 86 bus network routes. The second stage of the “Riyadh Bus” expansion witnesses the coverage of 1120 kilometres out of 1900 kilometres of the total service.

Prior to the different launches of the service, the network underwent testing and trial running to ensure that service delivery capability meets the highest operational and safety standards. During the trial runs, the service performance was measured against a set of key performance indicators such as operated service, punctuality and trip completion. The operator and drivers’ skills and behavior, adherence to safety procedures, and vehicle condition and cleanliness were also measured during that stage, in addition to operations at the bus depot and the Control & Operation Center.
