Weitzer Railmotor
The railmotors of J. Weitzer ''Engine- & Waggon-Building & Iron Casting Joint-stock Company'' ( Hu.: ''Weitzer János Gép,- Waggongyár és Vasöntöde Részvénytársaság'') were Europe's first self-propelled railcars with internal combustion engine built in considerable numbers. The principle of their petrol–electric transmission and the four-cylinder petrol engines came from De Dion-Bouton in France. The electric engines were produced Siemens-Schuckert in Germany. The first cars were constructed in 1903, the series since 1906. Reports of their use can be added to a total of 65 sold railmotors and 40 trailers. Most of these railmotors were built for , 11 for metre gauge and 11 for . The last ones ran on petrol-electric traction till 1960. History The Hungarian minister of trade, Lajos Láng, started a campaign for the development of self-propelled railcars in order to economize passenger transport on secondary railroads. The producers involved were Ganz & Cie., Weitze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolling Stock Of Romania
Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as ''pure rolling''. By definition, there is no sliding when there is a frame of reference in which all points of contact on the rolling object have the same velocity as their counterparts on the surface on which the object rolls; in particular, for a frame of reference in which the rolling plane is at rest (see animation), the instantaneous velocity of all the points of contact (e.g., a generating line segment of a cylinder) of the rolling object is zero. In practice, due to small deformations near the contact area, some sliding and energy dissipation occurs. Nevertheless, the resulting rolling resistance is much lower than sliding friction, and thus, rolli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

McKeen Railmotor
The McKeen Railmotor was a 6-cylinder self-propelled railcar or railmotor. When McKeen Company of Omaha, Nebraska, U.S.A., first unveiled the car in 1905, the McKeen was among the first engines with a distillate-fueled motor. Revisions to the McKeen car led to the modern self-propelled gasoline rail-motor vehicle, and the "contours of the porthole windows, the front-mounted gasoline engines, and other features anticipated the streamline concept." Design William R. McKeen was the superintendent of motive power and machinery at Union Pacific Railroad in 1904 when Edward H. Harriman, the head of UP, began encouraging him to develop the machine. The result of his experiments that year was a "knife-nosed" or "windsplitter" unit that slightly resembled a submarine on wheels, having a distinctive pointed nose, a rounded rear end, center-entry doors and porthole windows. Two lengths, , were offered, and both could be configured with either a large mail and express area ahead of the cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow Collector
A bow collector is one of the three main devices used on tramcars to transfer electric current from the wires above to the tram below. While once very common in continental Europe, it was replaced by the pantograph or the trolley pole, itself often later replaced by the pantograph. Origins When the bow collector was first conceived by German inventor Ernst Werner von Siemens in the late 1880s, American inventor Frank J. Sprague of Virginia had just patented his trolley pole system of current collection from an overhead wire. To avoid contravening this patent, the Siemens company was forced to design its own, unique form of current collection, namely the bow collector. The bow collector was first used by the Siemens electric company in its early electric tramcars in either the late 1880s or early 1890s. The Hobart electric tramway system - the first of its kind in the Southern Hemisphere, opened in 1893 - used Siemens cars with very early bow collectors. Many other continental E ...

Nyíregyháza
Nyíregyháza (, sk, Níreďháza) is a city with county rights in northeastern Hungary and the county capital of Szabolcs-Szatmár-Bereg. With a population of 118,001, it is the seventh-largest city in Hungary and the second largest in the Northern Great Plain region. Its development has been ongoing since the 18th century, making it the economic and cultural center of the region. Nyíregyháza Zoo, with over 500 species, is recognized throughout Europe. Geography Nyíregyháza is located in Szabolcs-Szatmár-Bereg County in the northern Plain region, which also comprises Hajdú-Bihar County and Jász-Nagykun-Szolnok County. It is located in the center of Nyírség as an agricultural town. The boundaries of the city are often understood as a very broad frame, because generally the near suburbs are included in them. It is located at the intersections of routes 4, 41, 36, and 38, making the city easy to reach, lying at the crossroads to Sub-Carpathia and Transylvania. ...

Căile Ferate Române
Căile Ferate Române (; abbreviated as the CFR) is the state railway carrier of Romania. As of 2014, the railway network of Romania consists of , of which (37.4%) are electrified. The total track length is , of which (38.5%) are electrified. The CIA World Factbook lists Romania with the 23rd largest railway network in the world. The network is significantly interconnected with other European railway networks, providing pan-European passenger and freight services. CFR as an entity has been operating since 1880, even though the first railway on current Romanian territory was opened in 1854. CFR is divided into four autonomous companies: * ''CFR Călători'', responsible for passenger services; * '' CFR Marfă'', responsible for freight transport; * ''CFR Infrastructură'' or ''CFR S.A.'', manages the infrastructure on the Romanian railway network; and * ''Societatea Feroviară de Turism'', or SFT, which manages scenic and tourist railways. CFR is headquartered in Bucharest a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
