63-505: The name "VRH" comes from the engines' V configuration ("V"), their purpose as racing engines ("R"), and the fact that all of them have eight cylinders (with "H" being the eighth letter of the Latin alphabet ). In 1987, Nissan began work on an engine exclusively for race use; the result was the VEJ30 engine, developed by Yoshikazu Ishikawa. This engine was based on old technology, and was not

126-451: A General Electric electrical engineer, developed and patented a reliable direct current electrical control system (subsequent improvements were also patented by Lemp). Lemp's design used a single lever to control both engine and generator in a coordinated fashion, and was the prototype for all diesel–electric locomotive control. In 1917–18, GE produced three experimental diesel–electric locomotives using Lemp's control design. In 1924,

189-434: A V engine has a shorter length but is wider. This effect increases with the number of cylinders in the engine; the length difference between V-twin and straight-twin engines might be insignificant, however V8 engines have a significantly smaller length than straight engines. Compared with the less common flat engine , a V engine is narrower, taller and has a higher center of mass . The "V-angle" (or "included angle") between

252-511: A V12 engine is that of perfect primary and secondary balance. For V engines with fewer cylinders, the engine balance will depend on factors such as the firing interval, crankshaft counterweights and whether balance shafts are present. The crankpins on a V engine are usually shared by two cylinders from opposing banks, with an offset between the two cylinders. Alternative configurations are separate crankpins per cylinder (such as several V-twin engines) or articulated connecting rods (for example,

315-577: A VRH35L in the R390 GT1 . The VRH35ADE was used by Infiniti in their Indy race car. The VRH40ADE was used by Infiniti in their Indy race car. The VRH34A is one of two engines used in Nissan's GT500 -spec GT-R . The VRH50A was used in the Nissan R391 . The VRH34A and VRH34B are naturally aspirated engines used by Nissan in their GT-R Super GT race car from 2010. The VRH34A

378-480: A conventional diesel or electric locomotive would be unsuitable. An example is maintenance trains on electrified lines when the electricity supply is turned off. Another use is in industrial facilities where a combustion-powered locomotive (i.e., steam- or diesel-powered ) could cause a safety issue due to the risks of fire, explosion or fumes in a confined space. Battery locomotives are preferred for mines where gas could be ignited by trolley-powered units arcing at

441-463: A diesel–electric locomotive ( E 2 original number Юэ 001/Yu-e 001) started operations. It had been designed by a team led by Yury Lomonosov and built 1923–1924 by Maschinenfabrik Esslingen in Germany. It had 5 driving axles (1'E1'). After several test rides, it hauled trains for almost three decades from 1925 to 1954. An electric locomotive is a locomotive powered only by electricity. Electricity

504-423: A ground and polished journal that is integral to the axle. The other side of the housing has a tongue-shaped protuberance that engages a matching slot in the truck (bogie) bolster, its purpose being to act as a torque reaction device, as well as a support. Power transfer from motor to axle is effected by spur gearing , in which a pinion on the motor shaft engages a bull gear on the axle. Both gears are enclosed in

567-410: A high ride quality and less electrical equipment; but EMUs have less axle weight, which reduces maintenance costs, and EMUs also have higher acceleration and higher seating capacity. Also some trains, including TGV PSE , TGV TMST and TGV V150 , use both non-passenger power cars and additional passenger motor cars. Locomotives occasionally work in a specific role, such as: The wheel arrangement of

630-550: A higher power-to-weight ratio than DC motors and, because of the absence of a commutator , were simpler to manufacture and maintain. However, they were much larger than the DC motors of the time and could not be mounted in underfloor bogies : they could only be carried within locomotive bodies. In 1894, Hungarian engineer Kálmán Kandó developed a new type 3-phase asynchronous electric drive motors and generators for electric locomotives. Kandó's early 1894 designs were first applied in

693-498: A larger locomotive named Galvani , exhibited at the Royal Scottish Society of Arts Exhibition in 1841. The seven-ton vehicle had two direct-drive reluctance motors , with fixed electromagnets acting on iron bars attached to a wooden cylinder on each axle, and simple commutators . It hauled a load of six tons at four miles per hour (6 kilometers per hour) for a distance of one and a half miles (2.4 kilometres). It

756-410: A liquid-tight housing containing lubricating oil. The type of service in which the locomotive is used dictates the gear ratio employed. Numerically high ratios are commonly found on freight units, whereas numerically low ratios are typical of passenger engines. Electricity is typically generated in large and relatively efficient generating stations , transmitted to the railway network and distributed to

819-644: A locomotive as it carried a payload. The earliest gasoline locomotive in the western United States was built by the Best Manufacturing Company in 1891 for San Jose and Alum Rock Railroad . It was only a limited success and was returned to Best in 1892. The first commercially successful petrol locomotive in the United Kingdom was a petrol–mechanical locomotive built by the Maudslay Motor Company in 1902, for

882-486: A locomotive describes how many wheels it has; common methods include the AAR wheel arrangement , UIC classification , and Whyte notation systems. In the second half of the twentieth century remote control locomotives started to enter service in switching operations, being remotely controlled by an operator outside of the locomotive cab. The main benefit is one operator can control the loading of grain, coal, gravel, etc. into

945-484: A mid-train locomotive that is controlled remotely from the lead unit. The word locomotive originates from the Latin loco 'from a place', ablative of locus 'place', and the Medieval Latin motivus 'causing motion', and is a shortened form of the term locomotive engine , which was first used in 1814 to distinguish between self-propelled and stationary steam engines . Prior to locomotives,

1008-403: A separate fourth rail for this purpose. The type of electrical power used is either direct current (DC) or alternating current (AC). Various collection methods exist: a trolley pole , which is a long flexible pole that engages the line with a wheel or shoe; a bow collector , which is a frame that holds a long collecting rod against the wire; a pantograph , which is a hinged frame that holds

1071-483: A short three-phase AC tramway in Evian-les-Bains (France), which was constructed between 1896 and 1898. In 1918, Kandó invented and developed 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. In 1896, Oerlikon installed

1134-416: A steam locomotive was about two and a half times larger than the cost of supporting an equivalent diesel locomotive, and the daily mileage they could run was lower. Between about 1950 and 1970, the majority of steam locomotives were retired from commercial service and replaced with electric and diesel–electric locomotives. While North America transitioned from steam during the 1950s, and continental Europe by

1197-584: A success. For 1988, the VEJ30 was improved by Yoshimasa Hayashi and renamed the VRH30. Changes included increasing the displacement to 3.4 L (3,396 cc). This engine was, however, still based on the obsolete VEJ30, and development of the all-new VRH35 was started in parallel with the VRH30. In 1989, the VRH35 appeared as a new development engine and was used in the Nissan R89C . A 3.0-litre variant of

1260-574: A two-cylinder V-twin, was designed by Wilhelm Maybach and used in the 1889 Daimler Stahlradwagen automobile. The first V8 engine was produced in 1903, in the form of the Antoinette engine designed by Léon Levavasseur for racing boats and airplanes . The first V12 engine was produced the following year by Putney Motor Works in London , again for use in racing boats. The first V6 engine to reach production appeared soon after in 1908, by

1323-414: A year later making exclusive use of steam power for passenger and goods trains . The steam locomotive remained by far the most common type of locomotive until after World War II . Steam locomotives are less efficient than modern diesel and electric locomotives, and a significantly larger workforce is required to operate and service them. British Rail figures showed that the cost of crewing and fuelling

1386-484: Is 3.4 L (3,396 cc) and produces 450–500 PS (331–368 kW; 444–493 bhp) and over 290 lb⋅ft (393 N⋅m) of torque. The VRH34B is 3.4 L (3,396 cc) and produces 500–530 PS (368–390 kW; 493–523 bhp) and over 325 lb⋅ft (441 N⋅m) of torque. V engine A V engine , sometimes called a Vee engine , is a common configuration for internal combustion engines . It consists of two cylinder banks —usually with

1449-458: Is a locomotive whose primary power source is a steam engine . The most common form of steam locomotive also contains a boiler to generate the steam used by the engine. The water in the boiler is heated by burning combustible material – usually coal, wood, or oil – to produce steam. The steam moves reciprocating pistons which are connected to the locomotive's main wheels, known as the " driving wheels ". Both fuel and water supplies are carried with

1512-416: Is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of three forms: an overhead line , suspended from poles or towers along the track or from structure or tunnel ceilings; a third rail mounted at track level; or an onboard battery . Both overhead wire and third-rail systems usually use the running rails as the return conductor but some systems use

1575-522: Is that these power cars are integral part of a train and are not adapted for operation with any other types of passenger coaches. On the other hand, many high-speed trains such as the Shinkansen network never use locomotives. Instead of locomotive-like power-cars, they use electric multiple units (EMUs) or diesel multiple units (DMUs) – passenger cars that also have traction motors and power equipment. Using dedicated locomotive-like power cars allows for

1638-542: Is usually rather referred to as a multiple unit , motor coach , railcar or power car ; the use of these self-propelled vehicles is increasingly common for passenger trains , but rare for freight trains . Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by

1701-778: The Deutz Gasmotoren Fabrik in Germany for use as a generator for gasoline-electric railway engines . However, it was not until 1950 that the V6 engine was used in series production automobiles, with the first example being the Lancia V6 engine . This V6 engine used a 60-degree V angle and separate crankpins for each cylinder, to reduce the vibration issues experienced by earlier attempts at production V6 engines. Compared with an equivalent inline engine (the most common configuration for engines with less than six cylinders),

1764-590: The EMD FL9 and Bombardier ALP-45DP There are three main uses of locomotives in rail transport operations : for hauling passenger trains, freight trains, and for switching (UK English: shunting). Freight locomotives are normally designed to deliver high starting tractive effort and high sustained power. This allows them to start and move long, heavy trains, but usually comes at the cost of relatively low maximum speeds. Passenger locomotives usually develop lower starting tractive effort but are able to operate at

1827-691: The Stockton & Darlington Railway in the north-east of England, which was the first public steam railway in the world. In 1829, his son Robert built The Rocket in Newcastle upon Tyne. Rocket was entered into, and won, the Rainhill Trials . This success led to the company emerging as the pre-eminent early builder of steam locomotives used on railways in the UK, US and much of Europe. The Liverpool & Manchester Railway , built by Stephenson, opened

1890-421: The cylinder banks varies significantly between engines. Some engines have used a V-angle of 180 degrees (the same angle as a flat engine ), such as several Ferrari V12 engines. At the other end of the scale, the 1922-1976 Lancia V4 engine and the 1991–present Volkswagen VR6 engine use V-angles as small as 10 degrees, along with a single cylinder head used by both banks of cylinders. The engine balance of

1953-414: The driving wheels by a transmission. They typically keep the engine running at a near-constant speed whether the locomotive is stationary or moving. Internal combustion locomotives are categorised by their fuel type and sub-categorised by their transmission type. The first internal combustion rail vehicle was a kerosene -powered draisine built by Gottlieb Daimler in 1887, but this was not technically

2016-564: The edge-railed rack-and-pinion Middleton Railway ; this is generally regarded as the first commercially successful locomotive. Another well-known early locomotive was Puffing Billy , built 1813–14 by engineer William Hedley for the Wylam Colliery near Newcastle upon Tyne . This locomotive is the oldest preserved, and is on static display in the Science Museum, London. George Stephenson built Locomotion No. 1 for

2079-500: The traction motors and axles adapts the power output to the rails for freight or passenger service. Passenger locomotives may include other features, such as head-end power (also referred to as hotel power or electric train supply) or a steam generator . Some locomotives are designed specifically to work steep grade railways , and feature extensive additional braking mechanisms and sometimes rack and pinion. Steam locomotives built for steep rack and pinion railways frequently have

2142-412: The 1935 Daimler-Benz DB 601 V12 engines. It is common practice for V engines to be described with "V # " notation, where # represents the number of cylinders. Configurations of V engines which have reached production are as follows: Locomotive A locomotive is a rail transport vehicle that provides the motive power for a train . If a locomotive is capable of carrying a payload, it

2205-493: The 1970s, in other parts of the world, the transition happened later. Steam was a familiar technology that used widely-available fuels and in low-wage economies did not suffer as wide a cost disparity. It continued to be used in many countries until the end of the 20th century. By the end of the 20th century, almost the only steam power remaining in regular use around the world was on heritage railways . Internal combustion locomotives use an internal combustion engine , connected to

2268-648: The 40 km Burgdorf—Thun line , Switzerland. The first implementation of industrial frequency single-phase AC supply for locomotives came from Oerlikon in 1901, using the designs of Hans Behn-Eschenburg and Emil Huber-Stockar ; installation on the Seebach-Wettingen line of the Swiss Federal Railways was completed in 1904. The 15 kV, 50 Hz 345 kW (460 hp), 48 tonne locomotives used transformers and rotary converters to power DC traction motors. Italian railways were

2331-498: The Deptford Cattle Market in London . It was an 80 hp locomotive using a three-cylinder vertical petrol engine, with a two speed mechanical gearbox. Diesel locomotives are powered by diesel engines . In the early days of diesel propulsion development, various transmission systems were employed with varying degrees of success, with electric transmission proving to be the most popular. In 1914, Hermann Lemp ,

2394-747: The VRH35Z was also used in the 1998 Courage -Nissan C51 at the 1998 24 Hours of Le Mans . Both C51s failed to finish . The design of the engine was later sold to McLaren , where it served as the basis of their M838T and M840T engines (which were used in all of McLaren's line-up since the McLaren MP4-12C ). The VRH30T was used in the R88C . The VRH35Z first appeared in 1990 in the R90C . Displacement: 3.5 L (3,495 cc) In 1997, Nissan, working in partnership with Tom Walkinshaw Racing , fielded

2457-813: The boiler tilted relative to the locomotive frame , so that the boiler remains roughly level on steep grades. Locomotives are also used on some high-speed trains. Some of them are operated in push-pull formation with trailer control cars at another end of a train, which often have a cabin with the same design as a cabin of locomotive; examples of such trains with conventional locomotives are Railjet and Intercity 225 . Also many high-speed trains, including all TGV , many Talgo (250 / 350 / Avril / XXI), some Korea Train Express , ICE 1 / ICE 2 and Intercity 125 , use dedicated power cars , which do not have places for passengers and technically are special single-ended locomotives. The difference from conventional locomotives

2520-460: The center section would have a 200-ton reactor chamber and steel walls 5 feet thick to prevent releases of radioactivity in case of accidents. He estimated a cost to manufacture atomic locomotives with 7000 h.p. engines at approximately $ 1,200,000 each. Consequently, trains with onboard nuclear generators were generally deemed unfeasible due to prohibitive costs. In 2002, the first 3.6 tonne, 17 kW hydrogen (fuel cell) -powered mining locomotive

2583-407: The collecting shoes against the wire in a fixed geometry; or a contact shoe , which is a shoe in contact with the third rail. Of the three, the pantograph method is best suited for high-speed operation. Electric locomotives almost universally use axle-hung traction motors, with one motor for each powered axle. In this arrangement, one side of the motor housing is supported by plain bearings riding on

2646-455: The collection shoes, or where electrical resistance could develop in the supply or return circuits, especially at rail joints, and allow dangerous current leakage into the ground. Battery locomotives in over-the-road service can recharge while absorbing dynamic-braking energy. The first known electric locomotive was built in 1837 by chemist Robert Davidson of Aberdeen , and it was powered by galvanic cells (batteries). Davidson later built

2709-405: The driving wheels by means of connecting rods, with no intervening gearbox. This means the combination of starting tractive effort and maximum speed is greatly influenced by the diameter of the driving wheels. Steam locomotives intended for freight service generally have smaller diameter driving wheels than passenger locomotives. In diesel–electric and electric locomotives the control system between

2772-524: The early 1950s, Lyle Borst of the University of Utah was given funding by various US railroad line and manufacturers to study the feasibility of an electric-drive locomotive, in which an onboard atomic reactor produced the steam to generate the electricity. At that time, atomic power was not fully understood; Borst believed the major stumbling block was the price of uranium. With the Borst atomic locomotive,

2835-520: The first commercial example of the system on the Lugano Tramway . Each 30-tonne locomotive had two 110 kW (150 hp) motors run by three-phase 750 V 40 Hz fed from double overhead lines. Three-phase motors run at constant speed and provide regenerative braking , and are well suited to steeply graded routes, and the first main-line three-phase locomotives were supplied by Brown (by then in partnership with Walter Boveri ) in 1899 on

2898-514: The first in the world to introduce electric traction for the entire length of a main line rather than just a short stretch. The 106 km Valtellina line was opened on 4 September 1902, designed by Kandó and a team from the Ganz works. The electrical system was three-phase at 3 kV 15 Hz. 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

2961-697: The first recorded steam-hauled railway journey took place as another of Trevithick's locomotives hauled a train from the Penydarren ironworks, in Merthyr Tydfil , to Abercynon in South Wales. Accompanied by Andrew Vivian , it ran with mixed success. The design incorporated a number of important innovations including the use of high-pressure steam which reduced the weight of the engine and increased its efficiency. In 1812, Matthew Murray 's twin-cylinder rack locomotive Salamanca first ran on

3024-400: The high speeds required to maintain passenger schedules. Mixed-traffic locomotives (US English: general purpose or road switcher locomotives) meant for both passenger and freight trains do not develop as much starting tractive effort as a freight locomotive but are able to haul heavier trains than a passenger locomotive. Most steam locomotives have reciprocating engines, with pistons coupled to

3087-657: The locomotive, either on the locomotive itself, in bunkers and tanks , (this arrangement is known as a " tank locomotive ") or pulled behind the locomotive, in tenders , (this arrangement is known as a " tender locomotive "). The first full-scale working railway steam locomotive was built by Richard Trevithick in 1802. It was constructed for the Coalbrookdale ironworks in Shropshire in England though no record of it working there has survived. On 21 February 1804,

3150-675: The locomotives were retired shortly afterward. All four locomotives were donated to museums, but one was scrapped. The others can be seen at the Boone and Scenic Valley Railroad , Iowa, and at the Western Railway Museum in Rio Vista, California. The Toronto Transit Commission previously operated a battery electric locomotive built by Nippon Sharyo in 1968 and retired in 2009. London Underground regularly operates battery–electric locomotives for general maintenance work. In

3213-484: The motive force for railways had been generated by various lower-technology methods such as human power, horse power, gravity or stationary engines that drove cable systems. Few such systems are still in existence today. Locomotives may generate their power from fuel (wood, coal, petroleum or natural gas), or they may take power from an outside source of electricity. It is common to classify locomotives by their source of energy. The common ones include: A steam locomotive

3276-688: The power supply of choice for subways, abetted by the Sprague's invention of multiple-unit train control in 1897. The first use of electrification on a main line was on a four-mile stretch of the Baltimore Belt Line of the Baltimore & Ohio (B&O) in 1895 connecting the main portion of the B&;O to the new line to New York through a series of tunnels around the edges of Baltimore's downtown. Three Bo+Bo units were initially used, at

3339-475: The same number of cylinders in each bank—connected to a common crankshaft . These cylinder banks are arranged at an angle to each other, so that the banks form a "V" shape when viewed from the front of the engine. V engines typically have a shorter length than equivalent inline engines , however the trade-off is a larger width. V6 , V8 and V12 engines are the most common layout for automobile engines with 6, 8 or 12 cylinders respectively. The first V engine,

3402-425: The south end of the electrified section; they coupled onto the locomotive and train and pulled it through the tunnels. DC was used on earlier systems. These systems were gradually replaced by AC. Today, almost all main-line railways use AC systems. DC systems are confined mostly to urban transit such as metro systems, light rail and trams, where power requirement is less. The first practical AC electric locomotive

3465-486: The such as the Rolls-Royce Merlin aero engine). Some airplanes of the 1920s and 1930s used inverted engines , whereby the crankshaft is located at the top of the engine and the cylinder heads are at the bottom. Advantages include better visibility in a single-engined airplane, a higher thrust line, and resultant increased ground clearance for the propeller. Examples include the 1928 Argus As 10 V8 engine and

3528-464: The trains. Some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility . The railway usually provides its own distribution lines, switches and transformers . Electric locomotives usually cost 20% less than diesel locomotives, their maintenance costs are 25–35% lower, and cost up to 50% less to run. The earliest systems were DC systems. The first electric passenger train

3591-671: Was demonstrated in Val-d'Or , Quebec . In 2007 the educational mini-hydrail in Kaohsiung , Taiwan went into service. The Railpower GG20B finally is another example of a fuel cell–electric locomotive. There are many different types of hybrid or dual-mode locomotives using two or more types of motive power. The most common hybrids are electro-diesel locomotives powered either from an electricity supply or else by an onboard diesel engine . These are used to provide continuous journeys along routes that are only partly electrified. Examples include

3654-471: Was designed by Charles Brown , then working for Oerlikon , Zürich. In 1891, Brown had demonstrated long-distance power transmission, using three-phase AC , between a hydro-electric plant at Lauffen am Neckar and Frankfurt am Main West, a distance of 280 km. Using experience he had gained while working for Jean Heilmann on steam–electric locomotive designs, Brown observed that three-phase motors had

3717-426: Was presented by Werner von Siemens at Berlin in 1879. The locomotive was driven by a 2.2 kW, series-wound motor, and the train, consisting of the locomotive and three cars, reached a speed of 13 km/h. During four months, the train carried 90,000 passengers on a 300-metre-long (984 feet) circular track. The electricity (150 V DC) was supplied through a third insulated rail between the tracks. A contact roller

3780-943: Was tested on the Edinburgh and Glasgow Railway in September of the following year, but the limited power from batteries prevented its general use. Another example was at the Kennecott Copper Mine , Latouche, Alaska , where in 1917 the underground haulage ways were widened to enable working by two battery locomotives of 4 + 1 ⁄ 2 tons. In 1928, Kennecott Copper ordered four 700-series electric locomotives with on-board batteries. These locomotives weighed 85 tons and operated on 750-volt overhead trolley wire with considerable further range whilst running on batteries. The locomotives provided several decades of service using Nickel–iron battery (Edison) technology. The batteries were replaced with lead-acid batteries , and

3843-650: Was the first in the world in regular service powered from an overhead line. Five years later, in the U.S. electric trolleys were pioneered in 1888 on the Richmond Union Passenger Railway , using equipment designed by Frank J. Sprague . The first electrically worked underground line was the City & South London Railway , prompted by a clause in its enabling act prohibiting use of steam power. It opened in 1890, using electric locomotives built by Mather & Platt . Electricity quickly became

3906-546: 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. A battery–electric locomotive (or battery locomotive) is an electric locomotive powered by onboard batteries ; a kind of battery electric vehicle . Such locomotives are used where

3969-638: Was used to collect the electricity. The world's first electric tram line opened in Lichterfelde near Berlin, Germany, in 1881. It was built by Werner von Siemens (see Gross-Lichterfelde Tramway and Berlin Straßenbahn ). The Volk's Electric Railway opened in 1883 in Brighton, and is the oldest surviving electric railway. Also in 1883, Mödling and Hinterbrühl Tram opened near Vienna in Austria. It
