SU42
SU42 is a Polish diesel-electric locomotive used for light freight and passenger traffic purposes. History The SU42 is in fact the same locomotive as SM42 and SP42. The original class SU42 were modifications of class SM42 done during the 1970s. This modification involved the installation of a 500 volt electric train supply for carriage heating, supplied directly by locomotive's generator. The class retained the original SM42 serial number, however most of those converted have now been converted back to SM42 or withdrawn as the carriages using 500 V supply have been withdrawn. The second phase of modification was carried out between 1999 and 2000 from class SP42. The modification centered on the addition of 3 kV electric train supply. The modified locomotives were classified as class SU42-5xx. 40 of the class were eventually modified and they are based at various depots across the network. Unlike previous iteration, SU42-5xx has electric train heating powered by a separate Caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PKP Class SM42
SM42 is the PKP class for a Polish shunter diesel locomotive for shunting and light freight traffic, built by Fablok in Chrzanów (manufacturer's designation is Ls800E, designer's designation 6D). History The SM42 was the first Polish-designed heavier diesel-electric locomotive and was the most numerous one in its country of origin. Introduction The technical documentation for this locomotive was developed in 1958-1962 by the state Central Construction Bureau of Railway Stock Industry (CBKPTK) in Poznań, as type 6D. The production was given over to the Fablok Locomotive Factory in Chrzanów, where it was designated Ls800E (meaning an 800 HP diesel locomotive with electric transmission). The prototype was ready in December 1963. It was lent to the Polish State Railways (PKP), as the SM42-001, the class designation 'SM' meaning a diesel shunter locomotive, and was tested in Warsaw in 1964. Two improved locomotives were built for the PKP in 1964, and twenty in 1965. In 1967, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PKP Class SP42
SP42 is the name for a Polish diesel locomotive used for passenger services. History The SP42 is in fact the same locomotive as SM42, but modified for passenger transport. The modification was carried out by adding a heating system for passenger cars on the locomotive. Withdrawal of this class started in '90s, some of them was rebuilt into SU42 class (electrical heating instead of steam). SP42 class were totally withdrawn from PKP's service in year 2008. The last one (number 007 from depot Skarżysko Kamienna) made its special run with Bhp class double deckers from Skarżysko to Tomaszów Mazowiecki. Nicknames This loco used to be called the following names: *Łajka *Kociołek (eng. ''boiler'') - because of the steam heating system *Zebra - from the painting *Wibrator (eng. '' Vibrator'') - from vibrations produced by the engine *Eleska - from the factory number: Ls800 *Fablok - from the name of the producer See also *Polish locomotives designation PKP classification system (Po ...

Fablok
Fablok is a Polish manufacturer of locomotives, based in Chrzanów. Until 1947 the official name was ''First Factory of Locomotives in Poland Ltd.'' ( pl, Pierwsza Fabryka Lokomotyw w Polsce Sp. Akc.), Fablok being a widely used syllabic abbreviation of ''Fabryka Lokomotyw'', among others as the company's telegraphic address. It is now named "BUMAR - FABLOK S.A. (corporation)". Fablok is located in the town of Chrzanów in Lesser Poland. As of 2009, Fablok no longer builds new locomotives. History Early years 1919-1939 Fablok was established in 1919. A year later a contract was signed with the Polish government to supply 1,200 steam locomotives within ten years to the Polish State Railways (PKP). The first locomotive was delivered on 7 April 1924. In 1931, the first locomotive was exported to the Bulgarian State Railways. During 1935 and 1936, five electric locomotives were built under license from Metropolitan-Vickers. In 1935–1936, Fablok produced five Luxtorpedas (fast ...

Bo′Bo′
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives. Bo-Bo Bo-Bo is the UIC indication of a wheel arrangement for railway vehicles with four axles in two individual bogies, all driven by their own traction motors. It is a common wheel arrangement for modern electric and diesel-electric locomotives, as well as power cars in electric multiple units. Most early electric locomotives shared commonalities with the steam engines of their time. These features included side rods and frame mounted driving axles with leading and trailing axles. The long rigid wheelbase and the leading and trailing axles reduced cornering stability and increased weight. The Bo-Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel-electric Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover (locomotive), 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 engine, 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 transmission (mechanics), 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 le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Train Supply
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive (or a generator car) at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs. The maritime equivalent is hotel electric power. A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger cars on the London to Brighton route heralded the beginning of using electricity to light trains in the world. History Oil lamps were introduced in 1842 to light trains. Economics drove the Lancashire and Yorkshire Railway to replace oil with coal gas lighting in 1870, but a gas cylinder explosion on the train led them to abandon the experiment. Oil-gas lighting was introduced in late 1870. Electrical lighting was introduced in October 1881 by using twelve Swan carbon filament incandescent lamps ...

Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power station. Weight distribution The power unit rep ...

Electric Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromagnetic ...

The last steam locomotive was serviced in 1972. After the fall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pojazdy Szynowe Pesa Bydgoszcz
Pesa (Pojazdy Szynowe Pesa Bydgoszcz) is a Polish company manufacturing railway vehicles based in Bydgoszcz. The name 'Pesa' derives from the initials PS which stand for ''Pojazdy Szynowe,'' 'railway vehicles' in Polish. Pesa is a successor to the Bydgoszcz repair shops of PKP ''Polskie Koleje Państwowe,'' Polish State Railways. From the 1950s until 1998 the repair shops operated under the name ZNTK Bydgoszcz, ''Zakłady Naprawcze Taboru Kolejowego,'' 'Repair Shop for Railway Rolling Stock' in Bydgoszcz. For most of its history the Bydgoszcz shop overhauled and repaired steam locomotives and freight cars. After the collapse in 1989 of the Communist regime in Poland the ZNTK Bydgoszcz repair shop was spun off in 1991 as an independent company. This led to a re-thinking of the firm's activities, and in 2001 the company was renamed ''Pojazdy Szynowe Pesa Spółka Akcyjna Holding'' (its present name) and its activities were re-oriented away from repair to the construction of ...

Colorado Potato Beetle
The Colorado potato beetle (''Leptinotarsa decemlineata''), also known as the Colorado beetle, the ten-striped spearman, the ten-lined potato beetle, or the potato bug, is a major pest of potato crops. It is about long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. Native to the Rocky Mountains, it spread rapidly in potato crops across America and then Europe from 1859 onwards. Taxonomy The Colorado potato beetle was first observed in 1811 by Thomas Nuttall and was formally described in 1824 by American entomologist Thomas Say.see pp. 453–454: "Doryphora, Illig.: D. 10-lineata"./ref> The beetles were collected in the Rocky Mountains, where they were feeding on the buffalo bur, '' Solanum rostratum''. The genus ''Leptinotarsa'' is assigned to the chrysolmelid beetle tribe Chrysomelini (in subfamily Chrysomelinae). Description Adult beetles typically are in length and in width. They weigh 50-170 mg. The beetles ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vibrator (mechanical)
A vibrator is a mechanical device to generate vibrations. The vibration is often generated by an electric motor with an unbalanced mass on its driveshaft. There are many different types of vibrator. Typically, they are components of larger products such as smartphones, pagers, or video game controllers with a "rumble" feature. Vibrators as components When smartphones and pagers vibrate, the vibrating alert is produced by a small component that is built into the phone or pager. Many older, non-electronic buzzers and doorbells contain a component that vibrates for the purpose of producing a sound. Tattoo machines and some types of electric engraving tools contain a mechanism that vibrates a needle or cutting tool. Aircraft stick shakers use a vibrating mechanism attached to the pilots' control yokes to provide a tactile warning of an impending aerodynamic stall. Industrial vibrators Vibrators are used in many different industrial applications both as components and as individu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
