The Doha metro runs below central Doha for a length of approximately 40km. As part of this ambitious plan to develop a railway based public transport in Doha, Qatar Rail has appointed a Joint Venture comprising PORR, the Saudi Binladin Group and HBK Contracting for the design and construction of the Green Line. The Green Line runs east from Al Riffa to Al Mansoura in the west. There are eleven stations along this line.
