Franz Krull Sk Class
The Franz Krull ''Sk''-class is a class of steam locomotive built by the Franz Krull metal works of Tallinn, Estonia between 1931-1940. The ''Sk'' were narrow-gauged and used oil shale as fuel, since it is the primary energy source in Estonia. A total of 16 units were produced, of which none has survived. The last ''Sk'', ''Sk-156'', was scrapped in 1980 in Beloretsk, Russia, where it was actively used until scrapping.

Oil Shale
Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens. Based on their deposition environment, oil shales are classified as marine, lacustrine and terrestrial oil shales. Oil shales differ from oil-''bearing'' shales, shale deposits that contain petroleum ( tight oil) that is sometimes produced from drilled wells. Examples of oil-''bearing'' shales are the Bakken Formation, Pierre Shale, Niobrara Formation, and Eagle Ford Formation. Accordingly, shale oil produced from oil shale should not be confused with tight oil, which is also frequently called shale oil. Deposits of oil shale occur around the world, including major deposits in the United States. A 2016 estimate of global deposits set the total world resources of oil shale equivalent of of oil in ...

Steam Locomotives Of Estonia
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

Symbols Of Communism
Communist symbolism represents a variety of themes, including revolution, the proletariat, peasantry, agriculture, or international solidarity. Communist states, parties and movements use these symbols to advance and create solidarity within their cause. These symbols often appear in yellow on a red background. The flag of the Soviet Union incorporated a yellow-outlined red star and a yellow hammer and sickle on red. The flags of Transnistria, Vietnam, China, North Korea, Angola and Mozambique would all incorporate similar symbolism under communist rule. The hammer and sickle have become the pan-communist symbol, appearing on the flags of most communist parties around the world. Some parties have a modified version of the hammer and sickle as their symbol, most notably the Workers' Party of Korea which includes a hammer representing industrial workers, a hoe representing agricultural workers, and a brush (traditional writing-implement) representing the intelligentsia.

Occupation Of The Baltic States
The Baltic states of Estonia, Latvia and Lithuania were invaded and occupied in June 1940 by the Soviet Union, under the leadership of Stalin and auspices of the Molotov-Ribbentrop Pact that had been signed between Nazi Germany and the Soviet Union in August 1939, immediately before the outbreak of World War II. The three countries were then annexed into the Soviet Union (formally as " constituent republics") in August 1940. The United States and most other Western countries never recognised this incorporation, considering it illegal. On 22 June 1941, Nazi Germany attacked the Soviet Union and within weeks occupied the Baltic territories. In July 1941, the Third Reich incorporated the Baltic territory into its '' Reichskommissariat Ostland''. As a result of the Red Army's Baltic Offensive of 1944, the Soviet Union recaptured most of the Baltic states and trapped the remaining German forces in the Courland pocket until their formal surrender in May 1945.

Beloretsk
Beloretsk (russian: Белоре́цк; ba, Белорет, ''Beloret'') is a types of inhabited localities in Russia, town in the Republic of Bashkortostan, Russia, located on the Belaya (Aghidhel) River, Belaya River, from Ufa. Population: History Town-factories were a peculiar phenomenon in the town-planning in Russia in the 18th and 19th centuries. Beloretsk Iron Factory was built in 1762-1767 by merchants I. B. Tverdyshev and I. S. Myasnikov, who bought 170,041 ''desiatinas'' of land from Bashkirs of Belokatayskaya Volost. Builders and first workers of the factory were purchased serfdom in Russia, serfs from Kazan Governorate, Kazan, Nizhny Novgorod Governorate, Nizhny Novgorod, Penza Governorate, Penza, and Ryazan Governorates. Beloretsk itself was founded as a factory settlement in 1762. A Bulletin of 1776 says that the Beloretsk Iron Factory was built in 1762 and had two blast furnaces and fourteen sledge-hammers.

Narrow-gauge
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany
Germany, officially the Federal Republic of Germany (FRG),, is a country in Central Europe. It is the most populous member state of the European Union. Germany lies between the Baltic and North Sea to the north and the Alps to the south. Its 16 constituent states have a total population of over 84 million in an area of . It borders Denmark to the north, Poland and Czechia to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in what is now Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithi ...
