Jackshaft (locomotive)
A jackshaft is an intermediate shaft used to transfer power from a powered shaft such as the output shaft of an engine or motor to driven shafts such as the drive axles of a locomotive. As applied to railroad locomotives in the 19th and 20th centuries, jackshafts were typically in line with the drive axles of locomotives and connected to them by side rods. In general, each drive axle on a locomotive is free to move about one inch (2.5 cm) vertically relative to the frame, with the locomotive weight carried on springs. This means that if the engine, motor or transmission is rigidly attached to the locomotive frame, it cannot be rigidly connected to the axle. This problem can be solved by mounting the jackshaft on unsprung bearings and using side-rods or (in some early examples) chain drives.General Construction, Baldwin Gasoline Industrial LocomotiveBaldwin Locomotive Works Record No. 74, 1913; pages 7-9. Jackshafts were first used in early steam locomotives, although the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steam Turbine Locomotive
A steam turbine locomotive is a steam locomotive which transmits steam power to the wheels via a steam turbine. Numerous attempts at this type of locomotive were made, mostly without success. In the 1930s this type of locomotive was seen as a way both to revitalize steam power and challenge the diesel locomotives then being introduced. Advantages * High efficiency at high speed. * Far fewer moving parts, hence potentially greater reliability. * Conventional piston steam locomotives give a varying, sinusoidal torque, making wheelslip much more likely when starting. * The side rods and valve gear of conventional steam locomotives create horizontal forces that cannot be fully balanced without substantially increasing the vertical forces on the track, known as hammer blow. Disadvantages * High efficiency is ordinarily obtained ''only'' at high speed and high power output (though some Swedish and UK locomotives were designed and built to operate with an efficiency equal to or better th ...

Rhaetian Railway Ge 6/6 I
The Rhaetian Railway Ge 6/6 I is a class of metre gauge C′C′ electric locomotives operated by the Rhaetian Railway (RhB), which is the main railway network in the Canton of Graubünden, Switzerland. The class is so named because it was the first class of locomotives of the Swiss locomotive and railcar classification type ''Ge 6/6'' to be acquired by the Rhaetian Railway. According to that classification system, Ge 6/6 denotes a narrow gauge electric adhesion locomotive with a total of six axles, all of which are drive axles. Due to their shape – they are similar in form to the SBB-CFF-FFS Crocodiles of the Gotthard Railway – the Ge 6/6 I locomotives have also collectively been nicknamed the ''Rhaetian'' ''Crocodiles'' by rail fans. Their internal working RhB designation is ''C-C''. As with its standard-gauge counterpart, the Ge 6/6 is articulated, with a gear-driven Jackshaft between the two end axles of each unit ...

Crocodile (locomotive)
Crocodile (German ''Krokodil'') electric locomotives are so called because they have long "noses" at each end, reminiscent of the snout of a crocodile (see also Steeplecab). These contain the motors and drive axles, and are connected by an articulated center section. The center section usually contains the crew compartments, pantographs and transformer. The name was first applied to Swiss locomotives. Sometimes the term is applied to locomotives in other countries of a similar design. History Switzerland Class Ce 6/8 A prototype locomotive, SBB-CFF-FFS Ce 6/8 I number 14201, was ordered in June 1917. The production "Crocodiles" were the series ''SBB Ce 6/8 II'' and ''SBB Ce 6/8 III'' locomotives of the SBB, Swiss Federal Railways, built between 1919 and 1927. There were 33 class Ce 6/8 II and 18 class Ce 6/8 III, making a total (excluding the prototype) of 51 locomotives. These locomotives were developed for pulling heavy goods trains on the steep tracks of the Gotthar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR FF1
The Pennsylvania Railroad's class FF1 was an American electric locomotive, a prototype numbered #3931 and nicknamed "Big Liz". It was built in 1917 to haul freight trains across the Allegheny Mountains where the PRR planned to electrify. "Big Liz" proved workable but too powerful for the freight cars of the time with its 4600 available horsepower and astonishing of tractive effort. Pulling the train it regularly snapped couplers and when moved to the rear as a pusher its force was sufficient to pop cars in the middle of the train off the tracks. It had a 2-6-6-2 wheel arrangement in two half- frames, connected in the center. Each frame had a pair of three-phase AC induction motors driving a jackshaft through gearing and a spring drive; side rods then drove the wheels. The jackshafts can be mistaken for an additional fourth axle but the "wheels" are cogwheels to transfer power from the motors to the jackshaft. Three-phase power for the 4 massive motors was supplied from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR DD1
The Pennsylvania Railroad DD1 was a class of boxcab electric locomotives built by the Pennsylvania Railroad. The locomotives were developed as part of the railroad's New York Tunnel Extension, which built the original Pennsylvania Station in New York City and linked it to New Jersey via the North River Tunnels. The Pennsylvania built a total of 66 locomotives in its Altoona Works; they operated in semi-permanently coupled pairs. Westinghouse supplied the electrical equipment. The first locomotives entered service in 1910, with the opening of Pennsylvania Station. They operated between Manhattan Transfer and Pennsylvania Station, and from there to the coach yards at Sunnyside Yard in Queens, New York. With the arrival of the Class L5 locomotives in 1924, some DD1s moved to the Pennsylvania-owned Long Island Rail Road (LIRR), which had substantial electrified commuter rail operations. The conversion of the New York–Philadelphia main line to alternating current in the 1930s s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westinghouse Electric (1886)
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. The company acquired the CBS television network in 1995 and was renamed "CBS Corporation" until being acquired by Viacom in 1999, a merger completed in April 2000. The CBS Corporation name was later reused for one of the two companies resulting from the split of Viacom in 2006. The Westinghouse trademarks are owned by Westinghouse Electric Corporation, and were previously part of Westinghouse Licensing Corporation. The nuclear power business, Westinghouse Electric Company, was spun off from the Westinghouse Electric Corporation in 1999. History Westinghouse Electric was founded by George Westinghouse in Pittsburgh, Pennsylvania, on January 8, 1886. The firm became active in developing electric infrastructure throughout the U ...

Brown, Boveri & Cie
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network. Activity in Britain Brown Bove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maschinenfabrik Oerlikon
Maschinenfabrik Oerlikon was a Swiss engineering company based in the Zürich district of Oerlikon known for the early development of electric locomotives. It was founded in 1876 by the industrialist Peter Emil Huber-Werdmüller, and occupied a large site immediately to the west of Oerlikon railway station. In 1906 the armaments business was demerged to form ', which evolved into the technology company OC Oerlikon and the armaments company Rheinmetall Air Defence (formerly ''Oerlikon Contraves'').

Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles (electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control DC motor, Direct-current motors with series Field coil, field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...
