Makkah Mass Rail Transit Company planned to develop Al Mashaaer Al Mugaddassah Metro Line Project, in Mina, Makkah, Makkah, Saudi Arabia. The project covered the construction of 18.25 KM railway, 13.36 KM bridge, 4.71 KM road, 9 stations (including 3 departure stations & 3 arrival stations), and some other facilities. Serco Middle East was the operation & maintenance consultant of the project. China Railway Construction Corp Ltd was the EPC+O&M(Operation & Maintenance) contractor of the project who signed the contract in Feb 2009 responsible for EPC construction & 3-year operation of the project. In 2018, an O&M contract was awarded to China Railway Construction Corp Ltd again. The project was built separately from the Mecca Metro network. It was planned to be in operation during each year's Hajj period to help relieve traffic tension.(More than 3 million pilgrims came Makkah each year during Hajj period). It helped promise a safer, more comfortable pilgrimage. The line was claimed to be the world's fastest design in the world when being constructed.
