The Saudi Railways Organization (SRO) (Arabic: المؤسسة العامة للخطوط الحديدية‎) is one of two state-owned companies that operates Saudi Arabia's rail network along with Saudi Railway Company. The SRO operates a network of railways with a total length of approximately 1,380 kilometers. The network consists of two main lines. A 449 km passenger line that links Dammam with Riyadh, and a 556 km freight line that connects the King Abdul Aziz Port in Dammam with Riyadh.

There are plans to extend the network to the Red Sea port of Jeddah and, eventually to the borders of Jordan, Yemen, and perhaps all the way to Egypt.[2]

Approval to merge Saudi Railways Organization and Saudi Railway Company was announced in February 2021.[3]


The first railway in modern Saudi Arabia was the Hejaz Railway, from the border of Jordan to Medina. This 1,050 mm (3 ft 5+1132 in) narrow gauge railway opened in 1908, but closed in 1920.

Modern railways were introduced in Saudi Arabia after World War II, to facilitate the transport of goods for the Arabian American Oil Company, or Aramco (now Saudi Aramco), from ports located on the coast of the Persian Gulf to warehouses in Dhahran. Construction began in September 1947, and the first line was inaugurated on 20 October 1951. Several development projects have been completed since then, including an extension of the line to Riyadh, construction of several passenger terminals and the opening of a dry port in Riyadh.[4]

The network consists of the following lines:

Dammam–Riyadh line

Main article: Dammam–Riyadh line

Cargo line

Planning for the line started in 1947 with an agreement between King Ibn Saud and ARAMCO to lay a 547 km (about 340 mi) freight line. Bechtel Construction Company was chosen to build the rail line and a sea port at the eastern end of the rail line at Dammam. Construction of the line began in September 1947. In 1948, veteran American railroad engineer James H. Gildea was hired to oversee the project. The most serious obstacle to building the rail line was the Persian Gulf shallows at Dammam. To allow deep draft vessels to unload, a rail causeway of approximately seven miles was built out into the Persian Gulf with the first five miles a rock causeway and the last couple of miles a section made of a steel trestle. One of the first vessels to unload was a Dutch freighter, in 1950, with a load of rails for construction of the line. The first trains started moving between Dammam and Riyadh in the early 1950s.[5]

Branch lines

Rolling stock

Spanish manufacturer CAF delivered eight fast diesel locomotives in 2012, with one driving van trailer passenger car and four other passenger cars, with a leading power car unit; plus two spare power cars. They are used on the Dammam–Riyadh Line. During 2013 the travel time is 4:15 but there is a target of 3:00 for the future.
