The R class of the Swedish State Railways (SJ) was a type of steam locomotive built between 1908 and 1909. The class was built primarily to pull heavy iron ore trains on the Iron Ore Line in northern Sweden.
As the iron ore trains became heavier in the early 1900s, it became obvious to the Swedish State Railways that their M class of locomotives could not pull the heavier trains without the help of a pusher engine. SJ then placed an order of five locomotives with a 0-10-0 configuration. The class was at its introduction in 1908 the most powerful steam locomotive built in Sweden, a record which lasted until 1930 when the M3t class was introduced.
In 1914 the electrification of the Iron Ore Line had begun, thus making the R class unnecessary at the Iron Ore line, and the locomotives were transferred south to be used in regular freight trains. In 1935 two locomotives were sold to the private railway Gävle-Dala Järnväg. In 1963 one locomotive (R 975) was sent to Denmark as a part of a deal to bring the F1200 locomotive of the F class. R975 was subsequently scrapped in Denmark in 1963. Of the remaining four locomotives in Sweden, three were scrapped in 1973. The last locomotive was preserved and is kept in running order by the Swedish Railway Museum, which uses the locomotive in heritage trains on special occasions.
Under the Whyte notation for the classification of steam locomotives, 4-6-2 represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The 4-6-2 locomotive became almost globally known as a Pacific type after a New Zealand locomotive that was shipped across the Pacific Ocean.
A 2-8-8-4 steam locomotive, under the Whyte notation, has two leading wheels, two sets of eight driving wheels, and a four-wheel trailing truck. The type was generally named the Yellowstone, a name given it by the first owner, the Northern Pacific Railway, whose lines ran near Yellowstone National Park. Seventy-two Yellowstone-type locomotives were built for four U.S. railroads.
A 4-6-0 steam locomotive, under the Whyte notation for the classification of steam locomotives by wheel arrangement, has four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels.
Under the Whyte notation for the classification of steam locomotives, 0-6-2 represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and two trailing wheels on one axle.
The London, Brighton and South Coast Railway (LB&SCR) A1 class is a class of British 0-6-0T steam locomotive. Designed by William Stroudley, 50 members of the class were built in 1872 and between 1874 and 1880, all at Brighton railway works. The class has received several nicknames, initially being known as "Rooters" by their south London crews. However, the engines were more famously known as "Terriers" on account of the distinctive 'bark' of the exhaust beat. Later in their careers, some engines were known as "Hayling Billy" on account of their work on the Hayling Island branch line. A pub of this name on the island was briefly home to the engine which is now No. W8 Freshwater.
The NZR C class consisted of twenty-four steam locomotives built to perform shunting duties on New Zealand's national rail network. It is sometimes known as the big C class to differentiate it from the C class of 1873.
The Iron Ore Line is a 398-kilometre (247 mi) long railway line between Riksgränsen and Boden in Norrbotten County, Sweden, owned by Trafikverket. The line also contains two branches, from Kiruna to Svappavaara and from Gällivare to Koskullskulle. The term is often colloquially used to also include the Ofoten Line, from Riksgränsen to Narvik in Norway, and the northernmost part of the Main Line Through Upper Norrland from Boden to Luleå. The railway from Narvik to Luleå is 473 kilometres (294 mi) long.
LKAB Malmtrafik, earlier Malmtrafik i Kiruna AB (MTAB), is a Swedish railway company which operates the iron ore freight trains on the Iron Ore Line and the Ofoten Line. MTAB is a wholly owned subsidiary of the mining company Luossavaara–Kiirunavaara (LKAB). In Norway, operations are handled by the subsidiary Malmtrafikk AS (MTAS). Malmtrafik hauls ore from LKAB's mines in Kiruna, Malmberget and Svappavaara to the ports of Luleå and Narvik, the latter located in Norway. The company owns 28 Iore locomotives and 750 hopper cars. Each train is 68 cars long and weighs 8,600 tonnes, allowing the company to transport 33 million tonnes per year.
Dm and Dm3 is a series of locomotives used by Swedish State Railways and later Malmtafik i Kiruna (MTAS) for pulling iron ore trains on the Iron Ore Line in Sweden and Ofoten Line in Norway. A total of 39 double-locomotives (Dm) were delivered between 1954 and 1971, built by ASEA. A further 19 center locomotives (Dm3) were later delivered. Norwegian State Railways also operated 12 similar locomotives, designated NSB El 12. The Dm is a articulated, freight-optimized version of the Da-locomotive.
The SJ Class Ma is an electric locomotive used by Swedish State Railways and later other railways. 41 units were built by ASEA between 1953 and 1960. It is derived from the older Mg-series, but unlike its predecessor it is used for freight and passenger trains. It is also the longest used loco in Sweden.
U is a class of 152 electric shunter locomotives operated by the Swedish State Railways and Trafikaktiebolaget Grängesberg–Oxelösunds Järnvägar (TGOJ) of Sweden, and the Norwegian State Railways (NSB), LKAB and Norsk Jernverk of Norway. They were built by ASEA, Nyqvist och Holm, Motala, ASJ Falun and Thune between 1926 and 1956. NSB gave the class the designation El 10.
O is a series of electric locomotives used by Swedish State Railways for hauling heavy iron ore trains on the Iron Ore Line in Sweden. The type Oa locomotives were built by Siemens and type Ob were built by ASEA.
The Swedish State Railways class E10 was a type of steam locomotive which was used for freight traffic. Ten locomotives were built in 1947 as a slightly modified version of the older E9 class. They were used mainly on the Inland Line, before being placed in the strategic reserve, where some remained until 1990; five of them have been preserved.
The A class of the Swedish State Railways (SJ) was a type of steam locomotive built in 1906–1909 for hauling mainline express trains. The 26 locomotives were built to replace older types that could not cope with the increasingly heavy express trains, but soon became insufficient themselves. They were relegated to less important passenger trains, and five were transferred to then-independent Ostkustbanan (OKB) in the 1920s, but returned when that company was nationalized in 1933.
The B class of the Swedish State Railways (SJ) was a type of steam locomotive for mixed traffic, introduced in 1909. 96 locomotives were built for SJ by between 1909 and 1919. The 4-6-0 B class was part of the development of modern superheated locomotives that had begun with the A class in 1906. Intended for fast freight trains and heavy stopping passenger trains, they proved to be highly useful in all types of traffic, and remained in use until the end of steam operations in Sweden.
The E, E2 and E5 classes of the Swedish State Railways (SJ) were three closely related types of steam locomotives. The E class 0-8-0 locomotives were part of the development of modern superheated types that had begun with the A class in 1906, and were intended for both mixed traffic in Norrland and heavy freight trains in southern Sweden. Many of them were rebuilt to the 2-8-0 E2 class between 1935 and 1951, enabling a speed increase from 65 kilometres per hour (40 mph) to 70 km/h (43 mph). Three E class locomotives built for private railways became known as the E5 class following nationalization, as they were slightly heavier than the ones built for SJ.
The Mb, later G12 class of Halmstad–Nässjö Järnväg (HNJ), known after nationalization in 1945 as the E9 class of the Swedish State Railways (SJ), was a type of steam locomotive built primarily for freight traffic. They were the basis for the nearly identical SJ E10 class.
The passenger train locomotives number 27–29 of Stockholm–Roslagens Järnvägar, usually referred to as stortyskarna, were the largest steam locomotives ever built for the Swedish three foot gauge railways. Initially used in fast passenger trains from Stockholm to Rimbo and Hallstavik, they were moved to freight service after the Stockholm–Rimbo Line was electrified in 1946. They hauled iron ore from Dannemora mine and transporter wagons from Uppsala, but were replaced by diesel locomotives during the 1950s. Two locomotives were leased at different times to the narrow-gauge network in Västergötland. Their last service was between Rimbo and Hallstavik in 1960. SRJ 28 has been preserved.
The Chicago and North Western R-1 class was a class of 325 4-6-0 "Ten-Wheeler" steam locomotives built by the Schenectady Locomotive Works, the American Locomotive Company, and the Baldwin Locomotive Works from 1901 to 1908. The R-1 locomotives were so large and so heavy that the Chicago and North Western (C&NW) Railroad had to extensively rebuild their trackage, bridges, tunnels, turntables, and enginehouses to accommodate them.
The Manila Railway 70 class of 1908 was a class of at least twenty-two 0-6-2 side and well-tank locomotives built by the North British Locomotive Company. These locomotives were first put into service on a mainline during the late 1900s and early 1910s by the Manila Railway Company. Their primary purpose was to support the growing network and replace the aging Dagupan class engines. They were used on all the lines of the Manila Railway and its succeeding incarnation, the Manila Railroad. Over time, some locomotives were either scrapped or given to sugarcane plantations after being withdrawn. The last unit, No. 79, remained in service with the Pampanga Sugar Development Company as late as 1989.
