Question: Where was the steam engine restored to operational condition in 2014 built for? 

full_context: Document 1: Southern Pacific class AC-9: The AC-9 was one of two Southern Pacific Railroad's articulated steam locomotive class that ran smokebox forward after 1920. Twelve AC-9 class locomotives were built by Lima in 1939 and were Southern Pacific's largest and heaviest steam engines, partly a consequence of low quality coal these engines were designed to burn. The AC-9s were partially streamlined (the only articulated steam engines to be so equipped), having "skyline casings" inspired by Lima's GS series of 4-8-4's, also made for Southern Pacific, and were equipped with coal tenders, unlike the cab forwards. The wheel arrangement was 2-8-8-4, which was nicknamed "Yellowstone". Between 1939 and 1952, all the twelve AC-9 engines were in service between Tucumcari, New Mexico, El Paso, Texas, and Tucson, Arizona, where they mainly pulled freight trains and occasionally also passenger trains such as the "Golden State Limited". In 1952, they were converted to burn oil instead of coal, and moved to Southern Pacific's Modoc line between Sparks, Nevada, and Alturas, California, where they worked in freight service from 1953 until retirement in 1956.
Document 2: KUR EC class: The KUR EC class was a class of gauge 4-8-2+2-8-4 Garratt-type articulated steam locomotives. The four members of the class, built by Beyer, Peacock & Co. in Manchester, England, were the first Garratts to be ordered and acquired by the Kenya-Uganda Railway (KUR). They entered service in 1926, and, after a relatively short but successful career with the KUR, were sold and exported to Indo-China in August 1939.
Document 3: South Australian Railways 500 class (steam): The South Australian Railways 500 class was a class of 4-8-2 steam locomotives operated by the South Australian Railways. They were rebuilt as 4-8-4s.
Document 4: New South Wales AD60 class locomotive: The AD60 class were Beyer-Garratt patent articulated four-cylinder, simple, non-condensing, coal-fired superheated, 4-8-4+4-8-4 heavy goods steam locomotives built by Beyer, Peacock and Company for the New South Wales Government Railways in Australia.
Document 5: LMS Stanier Class 5 4-6-0 44686/7: The last two of the 842 LMS Stanier Black Fives, numbers 44686 and 44687 were constructed by British Railways at Horwich Works in 1951. They were fitted with Caprotti valve gear, raised running plates without splashers, a double chimney and SKF roller bearings on all axles. Caprotti valve gear had previously been fitted to a batch of twenty Black Fives, nos. 44738-57, built in 1948. The valve gear on these was driven by one drive-line between the frames, driven from the leading coupled axle. Although these locomotives developed a great deal of power at high speeds and were free in coasting, acceleration at low speeds was poor. 44686 and 44687 were fitted with a modified form of valve gear, with an external shaft on each side, driven by a worm gear mounted on a flycrank attached to the driving axle. The British Caprotti valve gear was a new development of Caprotti valve gear by the Associated Locomotive Engineers, under the leadership of L.A. Daniels.
Document 6: GWR 6000 Class: The Great Western Railway 6000 Class or King is a class of 4-6-0 steam locomotive designed for express passenger work. With the exception of one Pacific ("The Great Bear"), they were the largest locomotives the GWR built. They were named after kings of the United Kingdom and of England, beginning with the reigning monarch, King George V, and going back through history. Following the death of King George V, the highest-numbered engine was renamed after his successor; and following the abdication of the latter, the next-highest engine was also renamed after the new King.
Document 7: 6029: 6029 is a four-cylinder, simple, non-condensing, superheated, articulated 4-8-4+4-8-4 steam engine, of the AD60 class, built by Beyer, Peacock and Company, Manchester, England, for the New South Wales Government Railways. It was restored to operational condition in 2014.
Document 8: Southern Pacific 4460: Southern Pacific 4460 is the only surviving GS-6 Class steam locomotive. The GS-6 is a semi-streamlined 4-8-4 Northern type steam locomotive. GS stands for "Golden State". The locomotive was built by the Lima Locomotive Works for the Southern Pacific Railroad in 1943. The GS-6 lacked side skirting and red and orange "Daylight" paint found on previous locomotives of the GS class, and were painted black and silver instead. This was because the US government controlled locomotive manufacturers during World War II and had turned down Southern Pacific's order of fourteen new Daylight locomotives. Southern Pacific re-designed the engine for general service and it was finally approved, but the government took four of them and gave them to the smaller and power-starved Western Pacific Railroad. Their smaller size when compared to previous GS class locomotives and the fact that they were built during World War II earned them the nicknames of "War Babies" and "Baby Daylights".
Document 9: Santa Fe 2926: Santa Fe 2926 is a former Atchison, Topeka and Santa Fe Railway (Santa Fe) 4-8-4 steam locomotive originally built in 1944 by Baldwin (const #69814). This locomotive was part of the last group of steam passenger locomotives (class 2900) built for the Santa Fe railway. This class of locomotives were the heaviest 4-8-4's built in the United States, and among the largest. The railroad used the locomotive in both fast freight and passenger service, accumulating over one million miles of usage before its last revenue run on December 24, 1953. The locomotive and a caboose were donated to the city of Albuquerque, New Mexico in 1956 in recognition of the city's 250th anniversary, and placed in a city park.
Document 10: South Australian Railways 520 class: The South Australian Railways 520 class was a class of 4-8-4 steam locomotives operated by the South Australian Railways.
Document 11: River Don Engine: The River Don Engine is a 1905-built steam engine used for hot rolling steel armour plate. It is a 3-cylinder simple engine of 40 in diameter, 48 in stroke. At its operating steam pressure of 160psi, it developed 12000 hp , and was able to reverse from full speed in 2 seconds. The rapid reverse was an essential feature of an engine used for rolling, as delays would result in cooling of the workpiece. This engine was one of four built to the same design, one going overseas to the Japanese Government, one to John Brown's Atlas plant, and the destination of the final one being William Beardmore of Glasgow. It is claimed to be one of the most powerful steam engines ever built, and the most powerful remaining in Europe.
Document 12: UR G class: The UR G class, known later as the UR / KUR GA class, and later still as the KUR EB class, was a class of gauge 4-8-0 steam locomotives built by Nasmyth, Wilson and Company in Patricroft, Salford, England, for the Uganda Railway (UR). The seven members of the class entered service on the UR in 1914, and continued in service after the UR was renamed the Kenya-Uganda Railway (KUR) in 1926.
Document 13: South Australian Railways 400 class: The South Australian Railways 400 class was a class of 4-8-2+2-8-4 steam locomotives built in the early 1950s. The 400 class locomotives mainly hauled mineral trains on the South Australian Railways' narrow gauge Broken Hill line from 1953 to 1963, when they were replaced by diesel locomotives. They operated as far as far south as Port Pirie and Terowie and as far north as Quorn. The 400 class was temporarily returned to service in 1969 while the diesel locomotives were converted to . Two have been preserved, 402 at the Zig Zag Railway, Lithgow and 409 at the National Railway Museum, Port Adelaide.
Document 14: New South Wales 79 class locomotive: In 1943, during World War II, four diesel-electric industrial shunting type locomotives built by General Electric Company, Erie for the United States Army Transportation Corps (USATC) were imported from the United States of America by the Department of Supply under Lend-Lease conditions for use at the Dunheved munitions factory in Sydney. They were four units of 58 units built for the USATC by General Electric numbered 8499-8528 & 7900-7929.
Document 15: South Australian Railways W class: The South Australian Railways W/Wx class was a class of 2-6-0 steam locomotives operated by the South Australian Railways and later the Commonwealth Railways.
