Iran has a state-owned railway system built to standard gauge (1,435 mm (4 ft 8½ in)) which falls under the remit of the Ministry of Roads & Urban Development. The primary rail carrier is the Islamic Republic of Iran Railways (abbreviated as IRIR, or sometimes as RAI, or as IRI Railway) which is the national state-owned railway system of Iran

In 2008, the IR operated 11,106 km of rail with a further 18,900 km in various stages of development. Almost all of this is standard gauge of 1,435 mm (4 ft 8+12 in), but 94 km are Russian gauge of 1,520 mm (4 ft 11+2732 in) to link up to ex-Soviet Union border states. There is also the no-longer-isolated Indian gauge section of 1,676 mm (5 ft 6 in) from Zahedan to the Pakistan border that continues to Quetta and the Indian sub-continent. The extent of double-track lines is 1,082 km. The Jolfa–Tabriz line is electrified (148 km). In 2006, IR reported that it possessed 565 engines, 1,192 passenger coaches, and 16,330 wagons. The vast majority of the engines are diesel-powered.
