Information: - A steam locomotive is a railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible materialusually coal/coke, wood, or oilto produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers). Both fuel and water supplies are carried with the locomotive, either on the locomotive itself or in wagons (tenders) pulled behind. The first steam locomotive, made by Richard Trevithick, first operated on 21 February 1804, three years after the road locomotive he made in 1801. The first practical steam locomotive was built in 1812-13 by John Blenkinsop. - The Milwaukee Road 's class F7 comprised six ( # 100 -- # 105 ) high - speed , streamlined 4 - 6 - 4 '' Baltic '' or '' Hudson '' type steam locomotives built by Alco in 1937 -- 38 to haul the Milwaukee 's Hiawatha express passenger trains . Following on from the success of the road 's class A 4 - 4 - 2s , the F7s allowed the road to haul heavier trains on the popular Chicago -- Twin Cities routes . The F7s are major contenders for the fastest steam locomotives ever built , as they ran at over 100 miles per hour ( 160 km / h ) daily . One run in January 1941 recorded by a reporter for Trains magazine saw 110 miles per hour ( 180 km / h ) achieved twice -- in the midst of a heavy snowstorm . Baron Gerard Vuillet , a French railroading expert , once recorded a run between Chicago and Milwaukee where the locomotive reached 125 mph ( 201 km / h ) and sustained an average 120 mph ( 190 km / h ) for 4.5 miles ( 7.2 km ) . However , the British locomotive LNER Class A4 4468 Mallard is officially accepted to be the world 's fastest , with a run recorded at 125.88 mph ( 202.58 km / h ) in 1938 . The Milwaukee F7s are accepted as the fastest steam locomotives by a different measure -- scheduled speed between stations . In 1939 , shortly after they were introduced into passenger service , the Twin Cities Hiawatha schedule was modified such that the engines would need to run the 78.3 mi ( 126.0 km ) between Portage and Sparta , Wisconsin in 58 minutes -- a start - to - stop average of 81 mph ( 130 km / h ) . First - built # 100 was also the first withdrawn from service , on November 10 , 1949 ; last - built # 105 was the final one in service , withdrawn August 10 , 1951 . All were scrapped . - On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. - Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels, six powered and coupled driving wheels and four trailing wheels. In France, where the type was first used, it is known as the Baltic, while it became known as the Hudson in most of North America.

Information: - Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Dusseldorf. - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. - The Spree is a river that flows through the Saxony, Brandenburg and Berlin states of Germany, and in the Usti nad Labem region of the Czech Republic. Approximately in length, it is a left bank tributary of the River Havel, which itself flows into the Elbe and then the North Sea. It is the river on which the original centre of Berlin was built. - The European Plain or Great European Plain is a plain in Europe and is a major feature of one of four major topographical units of Europe - the "Central and Interior Lowlands". It is the largest mountain-free landform in Europe, although a number of highlands are identified within it. - Berlin is the capital and the largest city of Germany as well as one of its constituent 16 states. With a population of approximately 3.5 million people, Berlin is the second most populous city proper and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has about 6 million residents from more than 180 nations. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers and lakes. - An urban area is a human settlement with high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets and in urban sociology or urban anthropology it contrasts with natural environment. The creation of early predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources leads to human impact on the environment. - Ronald Rauhe ( born 2 October 1981 in Berlin ) is a German sprint canoeist who has competed since 1997 . Competing in four Summer Olympics , he won a complete set of medals in the K - 2 500 m event ( gold : 2004 , silver : 2008 , bronze : 2000 ) . Rauhe has won 13 world championship gold medals ( 21 overall ) in the men 's kayak discipline , the most among all kayakers , breaking the tie he shared with Torsten Gutsche in 2010 . - Torsten Gutsche (born June 8, 1968 in Eisenhuttenstadt) is an East German-German sprint canoer who competed from the late 1980s to the late 1990s. Competing in two Summer Olympics, he won three golds (K-2 500 m: 1992, 1996; K-2 1000 m: 1992) and one silver (K-2 1000 m: 1996). What is the relationship between 'ronald rauhe' and 'canoer'?
