The first railway in Saudi Arabia was built by ARAMCO (Arabian American
Oil Company) in 1951 between Dammam and Riyadh. The line was later
taken over by the Saudi state. in 1985 a second line was opened between
Haffouf, Hasdd and Riyadh. This line is also used by passenger trains.
There is also a branch line between Dammam and King Abdulaziz port.
A 444km high-speed link will be built between Mecca and Medina. The
part Mecca-Jeddah will be double track, the rest will be single. The
entire line will be electrified at 25kV. Another project is the
"Landbridge" between the ports of Jeddah and Dammam: a 950km railway
between Riyadh and Jeddah, and a 115km line between Dammam and Jubail.
A third project is for a 2400km North-South railway between mines in
the North (Al Jalamidh and Az-Zabirah) to ports in the South (Ras Azour
and Jubail).
In 2009 1.1 million passengers and 3.6 million tonnes of freight were
