Rail.One will produce around 14,000 TB/ZB bi-block concrete sleepers for the 11.5km line, with production scheduled to begin in the first quarter of this year at its facility in Ha'il, Saudi Arabia.
The 25-station line is due to open in autumn 2015, and will link Education City with the Doha Metro network.
Siemens was awarded a turnkey contract last year covering signalling and communications systems, electrification, and depot equipment, as well as platform screen doors at four stations. Siemens will also supply a fleet of 19 Avenio low-floor LRVs, which will be equipped for catenary-free operation.
