total of 25 stations.

This third batch consists of the design and construction of lines 4 (yellow), 5 (green) and 6 (purple), which include twenty-five stations for which a total of 65 kilometers of subway tracks, 24 viaducts, 28 underground tracks and 13 surface tracks will be necessary .

The consortium, lead by FCC, are going to employ two TBMs of 9.77 metres diameter to construct the line 5 (green). The trains that will be travelling along these lines will have two carriages, operate without drivers and be supplied by Alstom. There will be four types of stations, elevated, surface, underground and transfer for connections between the various lines.

The six lines included in the overall metro project for Riyadh will have a total length of 175 kilometres, which will make it the largest suburban metro in the world currently in the project stage. Its construction will require 600,000 tonnes of steel, eighty times that employed in the construction of the Eiffel Tower, 4.3 million cubic metres of concrete, eleven times that used in Burj Khalifa, the highest skyscraper in the world, and over 30,000 workers, of which more than half correspond to the FCC batch.
