TheSaudi Railways Organization (SRO) (Arabic:المؤسسة العامة للخطوط الحديدية) was astate-owned railway company that operated part ofSaudi Arabia's rail network, along with the Saudi Railway Company (nowSaudi Arabia Railways). The SRO operated a network of railways with a total length of approximately 1,380 kilometers (860 mi). The network consisted of two main lines. A 449 km (279 mi) passenger line that linksDammam with Riyadh, and a 556 km (345 mi) freight line that connects theKing Abdul Aziz Port in Dammam with Riyadh.
There are plans to extend the network to theRed Sea port ofJeddah and, eventually, to the borders ofJordan,Yemen, and perhaps all the way toEgypt.[2]
Approval to merge the Saudi Railways Organization and theSaudi Railway Company was announced in February 2021.[3] The merger took place on 1 April 2021, and the merged entity is now known asSaudi Arabia Railways.[4]

Spanish manufacturerCAF 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.
