The Doha Metro is a planned rapid transit system in Qatar’s capital city that is scheduled to become operational by the end of 2019. It will have four lines with an approximate overall length of 300 km and 100 stations. It will be an integral component of the larger Qatar Rail network, which will include a long-distance rail for passengers and freight, linking Qatar to the GCC, and Lusail’s city local light rail transit. The Doha Metro will ultimately consist of four lines opening in phases beginning in 2019 with an eventual completion date of 2026. The Red, Green and Gold Lines will radiate out from a central interchange at Msheireb in Downtown Doha, with the Blue Line providing a semi-orbital service.
