  • PR RKH Opened Doha Metro May 8, 2019.Pdf
    RKH Qitarat, composed of RATP Dev, Keolis and Hamad Group, opened Doha Metro Red Line South On 8 May 2019, RKH Qitarat, the joint venture consisting of RATP Dev, Keolis and Hamad Group 1, opened the first section of the Doha metro to the public. This follows the award in December 2017 by Qatar Rail of a contract to operate and maintain Qatar’s first urban rail transport network for a period of 20 years. The network includes three automated metro lines in Doha, the Qatari capital, and four tram lines located in the city of Lusail. On 8 May 2019, the Doha Metro Red Line South opened to the public. Initial operation includes 13 out of 18 stations of the line, which will connect Al Qassar in the North to Al Wakrah in the South. For this first stage of the launch, service will be ensured from Sunday to Thursday, from 8am to 11pm. It is an important stage for testing the Doha Metro system with passengers, providing an opportunity to evaluate and review the performance in preparation for the full operation of the network in 2020. This major urban project is of crucial importance for the region as 90% of the Qatari population currently live in Doha and its surrounding suburbs (equivalent to 2.6 million people). Qatar wants to make the city of Doha more attractive to visitors and facilitate the daily journeys of the population as the country prepares for the post-fuel extraction era. The Doha metro will be completely automated and driverless, incorporating three lines (Red, Green and Gold) 75km of track and 37 stations.

  • __PRESS RELEASE RKH Qitarat, the Joint Venture Between RATP Dev
    RKH Qitarat, the joint venture between RATP Dev, Keolis (SNCF Group) and Hamad Group, will operate the first Qatar public transport network Doha, 7 December 2017 -- Qatar Rail, the national public transport operator, has awarded RKH Qitarat the operations and maintenance contract for the Doha automated metro and Lusail light rail networks. This emblematic contract, for a period of 20 years, is estimated to be worth three billion euros. The network will be launched in 2020. This is the first public transport network in Qatar and a key part of ‘Qatar Vision 2030’, a strategic plan established by the Qatari government in 2008, which sets the development and growth objectives for the emirate in the coming years. On 7 December 2017, Qatar Rail, the Qatari national public transport operator, awarded RKH Qitarat — the joint venture based on a consortium between RATP Dev and Keolis (49%) and the Qatari company Hamad Group (51%) — the operations and maintenance contract for the new automated metro of Doha, the capital of Qatar with more than two million residents, and a light rail network in Lusail. Lusail is located 15km from Doha’s city centre and is currently being built and, once completed, is expected to house 240,000 residents. PRESS RELEASE PRESS This major urban project is one of the most important for the region as 90% of the Qatari population currently live in Doha and its surrounding suburbs (equivalent to 2.6 million people) and 80% of which are foreign workers. Qatar Rail is currently in charge of building the new integrated urban transport network, which will include both the Doha metro and Lusail light rail.

    Article West Bay Business District in Doha, State of Qatar: Envisioning a Vibrant Transit-Oriented Development Deema Alattar 1, Raffaello Furlan 1,* , Michael Grosvald 2 and Rashid Al-Matwi 1 1 Department of Architecture and Urban Planning, Qatar University, Doha 3263, Qatar; [email protected] (D.A.); [email protected] (R.A.-M.) 2 Department of English Literature and Linguistics, Qatar University, Doha 2713, Qatar; [email protected] * Correspondence: [email protected] Abstract: In recent decades, Doha, the capital of Qatar, has experienced a large-scale transformation due to globalization and rapid economic growth. Recently, these changes have led to a focus on infrastructural development and the launch of the city’s metro project, whose success will depend heavily on Transit-Oriented Development (TOD). TOD focuses on the “3Ds” principles—design, density, and diversity—aiming to create walkable neighborhoods and well-integrated public trans- portation, with diverse mixed land uses and high-density, sustainable growth. In combining the concepts of livability, sustainable urbanism, and urban sociology, TOD leads to the creation of vibrant and active neighborhoods. The present research project focuses on TOD around Doha’s West Bay metro station, using the city’s central business district as a case study. The aim of this research project is to investigate the existing site conditions of the West Bay area, evaluate them with respect to TOD principles, and then propose a master plan for improved development. The final product of the research project is a proposal with design guidelines that are aimed at increasing the ridership of the Citation: Alattar, D.; Furlan, R.; West Bay metro station and creating a more attractive and dynamic neighborhood.

The contract was awarded by Qatar Rail. The order volume amounts to 8.989 billion QAR (approx. 1.858 billion Euros as per June 2013). Doha's Metro is an integral part of Qatar's raildevelopment programme. Consisting of four lines, the underground network will cover Doha's metropolitan area and establish connections to the city's central area as well as to various commercial and residential zones located in the city. In Doha's centre, the Metro will run under ground, while it will mostly run at street level or on elevated tracks in the suburban zones.
