Hohenzollern Locomotive Works
The Hohenzollern Locomotive Works (Aktiengesellschaft für Lokomotivbau Hohenzollern) was a German locomotive-building company which operated from 1872 to 1929. The Hohenzollern works was a manufacturer of standard gauge engines and about 400 fireless locomotives as well as diesel locomotives of various rail gauges. The company was founded on 8 June 1872 in Grafenberg near Düsseldorf. The firm produced around 4,600 locomotives. After the increasingly critical situation in the German locomotive building industry around 1929 the works was closed in November 1929. The Hohenzollern AG had hoped in vain for follow-on orders for the DRG Class 80 from the Deutsche Reichsbahn-Gesellschaft (DRG). Locomotive number 80 030 in the Bochum-Dahlhausen Railway Museum was one of the last that had been built by the Lokomotivbau Hohenzollern and is preserved today in photograph-grey livery. The last locomotives had left the factory in September 1929; it was then immediately torn down. Fire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limited Company
In a limited company, the liability of members or subscribers of the company is limited to what they have invested or guaranteed to the company. Limited companies may be limited by Share (finance), shares or by guarantee. In a company limited by shares, the liability of members is limited to the unpaid value of shares. In a company limited by guarantee, the liability of owners is limited to such amount as the owners may undertake to contribute to the assets of the company, in the event of being wound up. The former may be further divided in public companies (public limited company, public limited companies) and private companies (private limited company, private limited companies). Who may become a member of a private limited company is restricted by law and by the company's rules. In contrast, anyone may buy shares in a public limited company. Limited companies can be found in most countries, although the detailed rules governing them vary widely. It is also common for a distinct ...

Articulated Locomotive
An articulated locomotive is a steam locomotive (rarely, an electric locomotive) with one or more engine units that can move independent of the main frame. Articulation allows the operation of locomotives that would otherwise be too large to negotiate a railroad's curves, whether mainlines or special lines with extreme curvature such as logging, industrial, or mountain railways. Articulated locomotives saw service in many nations, but were very popular on narrow-gauge railways in Europe. The largest examples were developed in the United States, where the Union Pacific Big Boy 4-8-8-4s and the Allegheny H-8 2-6-6-6s were some of the largest steam locomotives ever built. Many schemes for articulation were developed over the years. Of these, the Mallet locomotive and its simple-expansion derivative were the most popular, followed by the Garratt type (mostly built in the United Kingdom, popular throughout Europe, Africa and European colonies), and the various geared steam locomot ...

South African Class 16DA 4-6-2
The South African Class 16DA 4-6-2 include two locomotive types, both designated Class 16DA in spite of their difference in respect of firebox size and performance. The first type was built by Hohenzollern Locomotive Works and Baldwin Locomotive Works in 1928 and 1929 respectively. The Henschel-built Class 16DA locomotives of 1930, with their much wider fireboxes, their correspondingly larger grate areas and slightly larger diameter trailing wheels were sufficiently different from the Baldwin and Hohenzollern-builts to justify a separate classification, such as Class 16DB, but this did not happen and the locomotives ended up being known as the Wide Firebox Class 16DA.Espitalier, T.J.; Day, W.A.J.

Maschinenfabrik Esslingen
Maschinenfabrik Esslingen (ME), was a German engineering firm that manufactured locomotives, tramways, railway wagons, roll-blocks, technical equipment for the railways, (turntables and traversers), bridges, steel structures, pumps and boilers. Founding It was founded by Emil Kessler on 11 March 1846 in Stuttgart, as a result of an initiative of the Kingdom of Württemberg to create a railway industry that was not dependent on foreign manufacturers. Emil Kessler brought vital experience from his time with the engineering works in Karlsruhe, where he had been a member of the board since 1837 and the sole director since 1842. The foundation stone of the new factory was laid at Esslingen am Neckar on 4 May 1846. One year later, in October 1847, the first locomotive ordered by the Royal Württemberg State Railways (''Königlich Württembergische Staats-Eisenbahnen'') or ''K.W.St. E.'' was delivered.

Iurii Vladimirovich Lomonosov
Yury Vladimirovich Lomonosov (russian: Юрий Владимирович Ломоносов; 24 April 1876 – 19 November 1952) was a Russian railway engineer and a leading figure in the development of Russian Railways in the early 20th century. He was best known for design and construction of the world's first operationally successful mainline diesel locomotive, the E el-2. This was completed in 1924 and went into service in 1925.Heywood, p.209 In the late 1920s, Lomonosov immigrated to Europe and later became a British citizen. Early years Lomonosov was born in 1876 in Gzhatsk (now Gagarin), a town in Smolensk Oblast of Russia. His father Vladimir Grigorievich Lomonosov was a former cavalry officer who worked as a judge since 1870. His mother Maria Fedorovna Lomonosova (née Pegelau) was a housewife known for establishing a public library.Norman E"Тепловоз профессора Ю.В.Ломоносова – первенец советского и мирового т ...

Russian Locomotive Class E El-2
The E el-2 (Cyrillic script: Ээл2) was a Soviet diesel-electric locomotive designed by Yury Lomonosov and built in Germany. The work was started by Hohenzollern Locomotive Works in Germany but, for political reasons, it was later transferred to Maschinenfabrik Esslingen. The locomotive was completed in 1924. On January 20, 1925 it was transferred to the USSR and presented to the press and officials. The rest of that year it spent on several mainline routes and then worked mostly between Moscow and Kursk, Russian SFSR, but later moved to Ashkhabad (Ashgabat, Turkmenistan). Despite some technical troubles in the early years of service, it underwent several modifications and lasted until 1954, running about a million kilometers in total. Powertrain The prime mover was an MAN submarine-type diesel engine, weighing 26 tonnes, and there were five traction motors, one for each driving axle.

Electromagnetic Clutch
Electromagnetic clutches operate electrically but transmit torque mechanically. This is why they used to be referred to as electro-mechanical clutches. Over the years, EM became known as electromagnetic versus electro-mechanical, referring more about their actuation method versus physical operation. Since the clutches started becoming popular over 60 years ago, the variety of applications and clutch designs has increased dramatically, but the basic operation remains the same today. Single-face clutches make up approximately 90% of all electromagnetic clutch sales. Electromagnetic clutches are most suitable for remote operation since no mechanical linkages are required to control their engagement, providing fast, smooth operation. However, because the activation energy dissipates as heat in the electromagnetic actuator when the clutch is engaged, there is a risk of overheating. Consequently, the maximum operating temperature of the clutch is limited by the temperature rating of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constant-mesh Gearbox
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the hydraulic automatic transmission (AT), and the continuously variable transmission (CVT), whereas the automated manual transmission (AMT) and dual-clutch transmissio ...

Russian Railways
Russian Railways (russian: link=no, ОАО «Российские железные дороги» (ОАО «РЖД»), OAO Rossiyskie zheleznye dorogi (OAO RZhD)) is a Russian fully state-owned vertically integrated railway company, both managing infrastructure and operating freight and passenger train services. The company was established on 18 September 2003, when a decree was passed to separate the upkeep and operation of the railways from the . RZhD is based in Moscow at Novaya Basmannaya str., 2. The operating units of the central part of the staff are at Kalanchevskaya str., 35. Railways in Crimea are controlled by Crimea Railway, a separate company. History Background and 2003 reform After the collapse of the Soviet Union in 1991, the Russian Federation inherited 17 of the 32 regions of the former Soviet Railways (SZD). By 1998, total freight traffic was half the 1991 figure. Government investment in the railway system was greatly curtailed, and passenger fares wer ...

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 ...
