on 15 July 1940. In 1941 the Iraqi State Railways PC class 4-6-2 steam locomotives were introduced to haul the Baghdad — Istanbul Taurus Express on the Baghdad Railway between Baghdad and Tel Kotchek. From 1941 onwards the UK War Department supplemented ISR's locomotive fleets: the metre gauge with HG class 4-6-0s requisitioned from India and new USATC S118 Class 2-8-2's from the US, and the standard gauge with new LMS Stanier Class 8F 2-8-0s and USATC S100 Class 0-6-0T's. In 1947 the Iraq Petroleum Company opened a branch at Kirkuk, which it operated with its own Hudswell Clarke 2-8-4T's from 1951. ISR opened a new metre gauge line from Kirkuk to Arbil in 1949. A joint road and rail bridge was opened across the River Tigris in Baghdad in 1950, finally connecting the east and west bank metre gauge systems. ISR added new steam locomotives in the 1950s: 20 metre gauge 2-8-2's from Ferrostaal of Essen and 10 from Vulcan Foundry in 1953 and 20 more from Maschinenfabrik Esslingen in 1955-56 and 2-8-0s from Krupp, plus standard gauge 2-8-0s also from Krupp. In 1958 when Iraq's Hashemite monarchy was overthrown and a republic declared, ISR was renamed Iraqi Republic Railways. In 1961 IRR began to replace its standard gauge steam locomotive fleet with diesels from ČKD and Alco. In 1972 several classes of steam locomotive were still in service on the standard gauge system, but these were replaced by further classes of diesel from Alstom, Montreal Locomotive Works and MACOSA. IRR did not begin to replace its metre gauge steam locomotives until after 1983. In 1964 IRR extended its standard gauge network with a line from Baghdad to Basrah which opened for freight in 1964 and for passengers in 1968. It has since been extended from Shouaiba Junction to the port of Umm Qasr. From 1980 until 2003 IRR suffered approximately one billion United States dollars' worth of war and looting damage. Passenger services In around October 2008, a commuter service resumed between Baghdad Central and the southern suburb of Doura. There is a nightly service between Baghdad and Basra and a Friday-only pilgrims service to Samarra. In March 2009, a weekly service started between Baghdad and Fallujah. The Baghdad - Mosul line is almost ready for passenger services to resume. Transport Minister Abdul Jabbar Ismail said that he hoped to extend the existing network of to between and
