The Ganz Machinery Works Holding is a Hungarian holding company . Its products are related to rail transport, power generation, and water supply, among other industries.
65-508: A railcar (not to be confused with a railway car ) is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach (carriage, car), with a driver's cab at one or both ends. Some railway companies, such as the Great Western , termed such vehicles " railmotors " (or "rail motors"). Self-propelled passenger vehicles also capable of hauling
130-470: A multiple-unit form, with one driver controlling all engines. However, it has previously been the practice for a railcar to tow a carriage or second, unpowered railcar. It is possible for several railcars to run together, each with its own driver (as practised on the former County Donegal Railway ). The reason for this was to keep costs down, since small railcars were not always fitted with multiple-unit control. There are also articulated railcars , in which
195-529: A body by American Car and Foundry , a Jacobs-Schupert boiler and a Ganz power truck in 1911. Numbered M-104, the experiment was a failure, and was not repeated. In 1904 the Automotor Journal reported that one railway after another had been realising that motor coaches could be used to handle light traffic on their less important lines. The North-Eastern railways had been experimenting “for some time” in this direction, and Wolseley provided them with
260-407: A dual-mode bus that can run on streets with rubber tires and on tracks with retractable train wheels. The term rail bus is also used at times to refer to a road bus that replaces or supplements rail services on low-patronage railway lines or a bus that terminates at a railway station (also called a train bus). This process is sometimes called bustitution . A UK company currently promoting
325-739: A fixed base, instead of running on bogies. Railbuses have been commonly used in such countries as the Czech Republic , France , Germany , Italy , Sweden , and the United Kingdom . A type of railbus known as a Pacer based on the Leyland National bus was still widely used in the United Kingdom until withdrawal in 2021. New Zealand railcars that more closely resembled railbuses were the Leyland diesel railcars and
390-423: A flat-four engine capable of up to 100 bhp (75 kW) for this purpose. The engine drove a main dynamo to power two electric drive motors, and a smaller dynamo to charge accumulators to power the interior lighting and allow electric starting of the engine. The controls for the dynamo allowed the coach to be driven from either end. For further details see 1903 Petrol Electric Autocar . Another early railcar in
455-989: A number of railcars for the Hungarian State Railways together with units with de Dion-Bouton boilers, Ganz steam motors and equipments, and Raba carriages built by the Raba Hungarian Wagon and Machine Factory in Győr . In 1908, the Borzsavölgyi Gazdasági Vasút (BGV), a narrow-gauge railway in Carpathian Ruthenia (today's Ukraine), purchased five railcars from Ganz and four railcars from the Hungarian Royal State Railway Machine Factory with de Dion-Bouton boilers. The Ganz company started to export steam motor railcars to
520-806: A single unit. Passengers may walk between the married pair units without having to open or pass through doors. Unit capacities range from 70 to over 300 seated passengers. The equipment is highly customisable with a wide variety of engine, transmission, coupler systems, and car lengths. Contrary to other parts of the world, in the United States these vehicles generally do not comply with Federal Railroad Administration (FRA) regulations and, therefore, can only operate on dedicated rights-of-way with complete separation from other railroad activities. This restriction makes it virtually impossible to operate them on existing rail corridors with conventional passenger rail service. Nevertheless, such vehicles may soon operate in
585-572: A solid technological superiority and revolutionized the world's milling industry. Budapest's milling industry grow the second largest in the world, behind the American Minneapolis. The Hungarian grain export increased by 66% within some years. In 1878, the company's general manager András Mechwart founded the Department of Electrical Engineering headed by Károly Zipernowsky . Engineers Miksa Déri and Ottó Bláthy also worked at
650-503: A stable output voltage, regardless of the actual load. In cooperation, Zipernovsky, Bláthy and Déri (known as the ZBD team) constructed and patented the transformer . The "transformer" was named by Ottó Titusz Bláthy. The three invented the first high efficiency, closed core shunt connection transformer. They also invented the modern power distribution system : Instead of a series of connections they connected supply transformers in parallel to
715-549: A train are, in technical rail usage, more usually called " rail motor coaches " or "motor cars" (not to be confused with the motor cars, otherwise known as automobiles, that operate on roads). The term is sometimes also used as an alternative name for the small types of multiple unit which consist of more than one coach. That is the general usage nowadays in Ireland when referring to any diesel multiple unit (DMU), or in some cases electric multiple unit (EMU). In North America

#1732783879601780-415: Is linked to Donát Bánki and János Csonka but it is not clear that they ever worked for Ganz. Ganz produced engines whose designs were licensed to Western European partners, notably in the United Kingdom and Italy. The Ganz Company started to construct steam locomotives and steam railcars from the 1860s. Between 1901 and 1908, Ganz Works of Budapest and de Dion-Bouton of Paris collaborated to build
845-599: Is sparse, and where the use of a longer train would not be cost effective . A famous example of this in the United States was the Galloping Goose railcars of the Rio Grande Southern Railroad , whose introduction allowed the discontinuance of steam passenger service on the line and prolonged its life considerably. Railcars have also been employed on premier services. In New Zealand , although railcars were primarily used on regional services,
910-820: The Blue Streak and Silver Fern railcars were used on the North Island Main Trunk between Wellington and Auckland and offered a higher standard of service than previous carriage trains. In Australia , the Savannahlander operates a tourist service from the coastal town of Cairns to Forsayth , and Traveltrain operates the Gulflander between Normanton and Croydon in the Gulf Country of northern Queensland . William Bridges Adams built steam railcars at Bow, London in
975-811: The California Western Railroad . While early railcars were propelled by steam and petrol engines, modern railcars are usually propelled by a diesel engine mounted underneath the floor of the coach. Diesel railcars may have mechanical ( fluid coupling and gearbox ), hydraulic ( torque converter ) or electric ( generator and traction motors ) transmission. Electric railcars and mainline electric systems are rare, since electrification normally implies heavy usage where single cars or short trains would not be economic. Exceptions to this rule are or were found for example in Sweden or Switzerland . Some vehicles on tram and interurban systems, like
1040-593: The Erzsébet Bridge in Budapest, for public road bridges in Yugoslavia and for several industrial halls. The Ganz Shipyard experienced its most productive times during the four decades following nationalisation. In the course of this period 1100 ship units were produced, the number of completed seagoing ships was 240 and that of floating cranes was 663. As a result of the great economic and social crises of
1105-588: The MÁVAG Locomotive and Machine Factory under the name of Ganz-MÁVAG Locomotive, Wagon and Machine Works. Of the products of the Works, outstanding results were shown in the field of the manufacture of diesel railcars and multiple units . Traditional products included tramcars as well, and customers included the tramway network of Budapest. In the meantime the Foundry workshop was closed down. In 1974,
1170-846: The Red Car of the Pacific Electric Railway , can also be seen as railcars. Experiments with battery-electric railcars were conducted from around 1890 in Belgium, France, Germany and Italy. In the US, railcars of the Edison-Beach type, with nickel-iron batteries were used from 1911. In New Zealand, a battery-electric Edison railcar operated from 1926 to 1934. In Ireland, the Drumm Battery Train used nickel-zinc batteries on four 2-car sets between 1932 and 1946 on
1235-655: The Roller Mill Plant (referred to as Hengermalom in Hungarian). In 1854 he began manufacturing hard cast railroad wheels in his own plant founded in 1844. The management of the steam mill paid a share of the profit to Ganz. This enabled him to buy, in 1844, land and a house for 4500 Forints in Víziváros, Buda castle district. Abraham Ganz built his own foundry on this site and started to work there with seven assistants. They made mostly casting products for
1300-581: The Wairarapa railcars that were specially designed to operate over the Rimutaka Incline between Wellington and the Wairarapa region. In Australia , where they were often called Rail Motors, railcars were often used for passenger services on lightly-used lines. In France they are known as autorails . Once very common, their use died out as local lines were closed. However, a new model has been introduced for lesser-used lines. In Canada , after
1365-619: The rotary phase converter , enabling electric locomotives to use three-phase motors whilst supplied via a single overhead wire, carrying the simple industrial frequency (50 Hz) single phase AC of the high-voltage national networks. After World War I , at the Ganz Works, Kálmán Kandó constructed a single-phase electric railway system using 16 kV at 50 Hz. A similar system, but using 15 kV at 16.7 Hz , later became widely used in Europe. The main attribute of Kandó's 50 Hz system

#17327838796011430-497: The 1840s. Many British railway companies tried steam rail motors but they were not very successful and were often replaced by push-pull trains . Sentinel Waggon Works was one British builder of steam railcars. In Belgium , M. A. Cabany of Mechelen designed steam railcars. His first was built in 1877 and exhibited at a Paris exhibition. This may have been the Exposition Universelle (1878) . The steam boiler
1495-748: The 1896 Millennium Exhibition, Röck and the Esslingen Machine Works presented a 6-tonne capacity artificial ice producing plant. In 1906, the first large Hungarian cold store (with a capacity of 3,000 tonnes, the largest in Europe) opened in Tóth Kálmán Street, Budapest, the machine was manufactured by the Ganz Works. Until nationalisation after the Second World War, large-scale industrial refrigerator production in Hungary
1560-600: The 1980s, Ganz-MÁVAG had to be reorganised. The company was transformed into seven independent Works and three joint ventures . In 1989, the British company Telfos Holdings gained a majority of the shares in Ganz Railway Vehicle Factory Co. Ltd. and the name of the company was changed to Ganz-Hunslet Co. Ltd. In the course of 1991 and 1992, the Austrian company Jenbacher Werke obtained 100% of
1625-553: The First World War, 116 naval vessels had been built by The Ganz-Danubius company. The company also produces transatlantic ocean liners for passenger lines Trieste - New York, Trieste - Montevideo, as a reflection of already formed wave of mass migration from Central Europe to America. The first Hungarian "aeroplane factory" ( UFAG ) was founded by the Ganz Company and Weiss-Manfréd Works in 1912. During World War I,
1690-598: The Ganz Company merged with the Danubius shipbuilding company , which was the largest shipbuilding company in Hungary. From 1911, the unified company adopted the "Ganz–Danubius " brand name. In the beginning of the 20th century the company had 19 shipyards on the Danube and the Adriatic Sea in the city of Rijeka and Pula. As Ganz Danubius, the company became involved in shipbuilding before, and during, World War I . Ganz
1755-630: The Ganz works. The voltage was significantly higher than used earlier and it required new designs for electric motors and switching devices. The three-phase two-wire system was used on several railways in Northern Italy and became known as "the Italian system". Kandó was invited in 1905 to undertake the management of Società Italiana Westinghouse and led the development of several Italian electric locomotives. In 1918, Kandó invented and developed
1820-706: The UK was designed by James Sidney Drewry and made by the Drewry Car Co. in 1906. In 1908 the manufacture was contracted out to the Birmingham Small Arms Company . By the 1930s, railcars were often adapted from truck or automobiles; examples of this include the Buick - and Pierce-Arrow -based Galloping Geese of the Rio Grande Southern Railroad , and the Mack Truck -based "Super Skunk" of
1885-406: The United Kingdom, Italy, Canada, Japan, Russia and Bulgaria. The Ganz Works, having identified the significance of induction motors and synchronous motors , commissioned Kálmán Kandó to develop them. In 1894, Hungarian engineer Kálmán Kandó developed high-voltage three-phase AC motors and generators for electric locomotives . The first-ever electric rail vehicle manufactured by Ganz Works
1950-600: The United States as manufacturers such as Siemens , Alstom and ADtranz affirm they may be able to produce FRA-compliant versions of their European equipment. Light regional railcars are used by a number of railroads in Germany, and also in the Netherlands , Denmark , Italy , United States and Spain . Models of new-generation multiple-unit and articulated railcars include: When there are enough passengers to justify it, single-unit powered railcars can be joined in
2015-499: The autumn of 1889, and the company was marketing the first induction kilowatt-hour meter by the end of the year. These were the first alternating-current wattmeters, known by the name of Bláthy-meters. In 1894, Hungarian inventor and industrialist István Röck started to manufacture a large industrial ammonia refrigerator (together with the Esslingen Machine Works) which was powered by Ganz electric compressors.

2080-576: The battery. A new breed of modern lightweight aerodynamically designed diesel or electric regional railcars that can operate as single vehicles or in trains (or, in “multiple units”) are becoming very popular in Europe and Japan, replacing the first-generation railbuses and second-generation DMU railcars, usually running on lesser-used main-line railways and in some cases in exclusive lanes in urban areas. Like many high-end DMUs, these vehicles are made of two or three connected units that are semi-permanently coupled as “married pairs or triplets” and operate as
2145-456: The beginning of the 20th century, 60 to 80% of the factory's products were sold for export. After the death of Abraham Ganz, the heirs entrusted the management of the factory to his direct colleagues at Ganz Művek: Antal Eichleter, Ulrik Keller and Andreas Mechwart, which then took the name Ganz & Co. The Ganz family sold the company, which consisted of five departments, and in April 1869 it
2210-608: The cessation of their mainline passenger service , BC Rail started operating a pair of railbuses to some settlements not easily accessible otherwise. In Russia , the Mytishchi -based Metrowagonmash firm manufactures the RA-1 railbus, equipped with a Mercedes engine. As of summer 2006, the Gorky Railway planned to start using them on its commuter line between Nizhny Novgorod and Bor . The term railbus also refers to
2275-548: The charge.[3] Ganz recognized that, to develop his factory, he had to make products that were mass-produced. In 1846 the Pest-Vác railway line was built. At that time, European foundries made wrought iron rims for spoked wagon wheels by pouring the casts in shapes in sand, and leaving them to cool down. He successfully developed a railway wheel casting technology; it was the new method of "crust-casting" to produce cheap yet sturdy iron railway wheels, which greatly contributed to
2340-450: The coastal and Harcourt Street railway lines . British Railways used lead–acid batteries in a railcar in 1958 . Between 1955 and 1995 DB railways successfully operated 232 DB Class ETA 150 railcars utilising lead–acid batteries . As with any other battery electric vehicle , the drawback is the limited range (this can be solved using overhead wires to recharge for use in places where there are not wires), weight, and/or expense of
2405-588: The company experienced its heyday and became the third-largest industrial enterprise in the Kingdom of Hungary after the Manfréd Weiss Steel and Metal Works and the MÁVAG company. Since 1989, various parts of Ganz have been taken over by other companies. The company was founded by Ábrahám Ganz in 1844. He was invited to Pest, Hungary , by Count István Széchenyi and became the casting master at
2470-574: The company made many types of Albatros and Fokker fighter planes. Before 1919, the company built ocean liners , dreadnought type battleships and submarines , power plants , automobiles and many types of fighter aircraft.

2990-473: The locomotive and wagon Works were merged under the name of Railway Vehicle Factory and then the machine construction branch went through significant development. The production of industrial and apartment house lifts became a new branch. Ganz-MÁVAG took over a lot of smaller plants in the 1960s and 1970s and their product range was extended. Among other things, they increased their bridge-building capacity. They made iron structures for several Tisza bridges, for
3055-579: The main line. The transformer patents described two basic principles. Loads were to be connected in parallel, not in series as had been the general practice until 1885. Additionally, the inventors described the closed armature as an essential part of the transformer. Both factors assisted the stabilisation of voltage under varying load, and allowed definition of standard voltages for distribution and loads. The parallel connection and efficient closed core made construction of electrical distribution systems technically and economically feasible. The Ganz Works built
