The SAR project is one of the largest railway projects in the world currently under construction, with a budget of more than US$30 billion. Major projects include the North-South Railway, the Saudi Land Bridge, and the MeccaMedina (or "Haramain") railway.
Upon completion, the SAR railway will be approximately 2,750 KM long. The SAR Project consists of two main lines, one originating in Riyadh running northwest toward Al Haditha near the Jordanian border. The second main line running from Al-Jalamid mine in the Northern province and then passing by Al-Jawf and Hail until "Al Baithah Junction," in Qassim province, then going east to the processing and export facilities in Ras AlKhair in the Eastern province on the coast of the Arabian Gulf.
