Bomlitz–Walsrode Railway
The Bomlitz–Walsrode railway is a railway line in the German state of Lower Saxony that is operated by the Osthannoversche Eisenbahnen (OHE). Route *Bomlitz–Gleisdreieck (triangular junction)–Cordingen (old Wolff Walsrode industrial siding) * Cordingen–Vogelpark–Walsrode (the former DB line from Walsrode to Visselhövede) Working in close cooperation with the railway today is the Walsrode branch of the '' Verden-Walsrode Railway Company'': *Walsrode–Vorwalsrode–Hollige– Altenboitzen (line belonging to the ''Verden-Walsroder Eisenbahn'', infrastructure only). History The gunpowder manufacturing company Wolff & Co. (later ''Wolff Walsrode AG'', now ''Dow Wolff Cellulosics'') opened an industrial railway from Cordingen to Bomlitz on 15 May 1915; the track ran as far as Kiebitzort at opening and was completed in 1916. At first only one steam locomotive was employed, but after a short time the line was electrified to a 600 volt, direct current system. For that, t ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Jordanbach
The Jordanbach is a river of Lower Saxony, Germany. It is a right-bank tributary of the Böhme. The Jordanbach lies entirely within the borough of Walsrode which is part of Heidekreis district in Lower Saxony. It is about long and has its source in the bog Vehmsmoor, which it drains. It flows in a southerly direction through Altenboitzen and discharges southwest of the village into the Böhme. The Jordanbach gives its name to a railway line between Bomlitz and Altenboitzen, that is nowadays only used for tourist purposes, such as the special trains of the Heath Express run by the Lüneburg Transport Society (''Arbeitsgemeinschaft Verkehrsfreunde Lüneburg''). This section of the Verden – Walsrode line operated by the Verden-Walsrode Railway, which was formed in 1910, is also called the Jordan-Bomlitz Railway, because it runs from the valley of the Jordanbach to the Bomlitz valley.

Heide Express
The Heide Express (literally: "Heath Express") is the name used by the Lüneburg Transport Society (Arbeitsgemeinschaft Verkehrsfreunde Lüneburg) or AVL to market special railway trips with their historic trains on the East Hanoverian Railways (OHE) railway network in northern Germany. Activities In addition to running special trains, the society organises presentations, model railway swapmeets, film showings and exhibitions, usually in Lüneburg. These are accompanied by excursions. Operations today The Heide Express operates today on the OHE lines around Lüneburg, Winsen, Soltau and Celle as well as Walsrode. Services operate irregularly several times a year and, in the summer months for special occasions. There are no regular weekend services as, for example, on the Moor Express. The following routes are operated: * Winsen (Luhe)–Niedermarschacht (with bus connexions to the Geesthacht Railway Society) * Winsen (Luhe)–Salzhausen–Hützel * Lüneburg–Bleckede (†...

Deutsche Bundesbahn
The Deutsche Bundesbahn or DB (German Federal Railway) was formed as the state railway of the newly established Federal Republic of Germany (FRG) on 7 September 1949 as a successor of the Deutsche Reichsbahn-Gesellschaft (DRG). The DB remained the state railway of West Germany until after German reunification, when it was merged with the former East German Deutsche Reichsbahn (DR) to form Deutsche Bahn, which came into existence on 1 January 1994. Background After World War II, each of the military governments of the Allied Occupation Zones in Germany were ''de facto'' in charge of the German railways in their respective territories. On 10 October 1946, the railways in the British and American occupation zones formed the ''Deutsche Reichsbahn im Vereinigten Wirtschaftsgebiet'' (German Imperial Railway in the united economic area), while on 25 June 1947, the provinces under French occupation formed the Südwestdeutsche Eisenbahn. With the formation of the FRG these succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellulose
Cellulose is an organic compound with the formula , a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton. Some animals, particularly ruminants and termites, can digest cellulose with the help of ...

Benzene
Benzene is an organic chemical compound with the molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline. It is used primarily as a precursor to the manufacture of chemicals with more complex structure, such as ethylbenzene and cumene, of which billions of kilograms are produced annually. Although benzene is a major industrial chemical, it finds limited use in consumer items because of its toxicity. History Discovery The word "''benzene''" derives from "''gum benzoin''" (benzoin res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Electric Locomotives
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of rec ...
