Electric-steam Locomotive
An electric-steam locomotive is a steam locomotive that uses electricity to heat the water in the boiler to create steam instead of burning fuel in a firebox. This is a highly unusual type of locomotive that only makes economic sense under specific conditions. Normally, it would be much more efficient to build and use an electric locomotive. However, lack of time and resources (as during wartime), lack of coal or similar fuel, and the presence of relatively cheap and available electricity may make conversion of an existing steam locomotive into an electric-steam locomotive a viable proposition. Switzerland Switzerland has no natural reserves of coal, but the mountainous region offers plentiful, and cheap, hydroelectricity. of SBB lines (73.6% of the network) were electrified by the outbreak of the Second World War, whilst the price of imported (German) coal kept rising. In an attempt to save on coal the Swiss Federal Railways fitted two small 0-6-0 steam shunters of class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crampton Locomotive
A Crampton locomotive is a type of steam locomotive designed by Thomas Russell Crampton and built by various firms from 1846. The main British builders were Tulk and Ley and Robert Stephenson and Company. Notable features were a low boiler and large driving wheels. The crux of the Crampton patent was that the single driving axle was placed behind the firebox, so that the driving wheels could be very large. This helped to give this design a low centre of gravity, so that it did not require a very broad-gauge track to travel safely at high speeds. Its wheel arrangement was usually or . Design variations Because the single driving axle was behind the firebox, Crampton locomotives usually had outside cylinders. However, some inside cylinder versions were built using indirect drive, then known as a ''jackshaft''. The inside cylinders drove a crankshaft located in front of the firebox and the crankshaft was connected to the driving wheels by outside rods. Some long-wheelb ...

The Railway Magazine
''The Railway Magazine'' is a monthly British railway magazine, aimed at the railway enthusiast market, that has been published in London since July 1897. it was, for three years running, the railway magazine with the largest circulation in the United Kingdom, having a monthly average sale during 2009 of 34,715 (the figure for 2007 being 34,661). It was published by IPC Media until October 2010, with , and in 2007 won IPC's 'Magazine of the Year' award. Since November 2010, ''The Railway Magazine'' has been published by Mortons of Horncastle. History ''The Railway Magazine'' was launched by Joseph Lawrence and ex-railwayman Frank E. Cornwall of Railway Publishing Ltd, who thought there would be an amateur enthusiast market for some of the material they were then publishing in a railway staff magazine, the ''Railway Herald''. They appointed as its first editor a former auctioneer, George Augustus Nokes (1867–1948), who wrote under the pseudonym "G. A. Sekon". He quickly ...

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, Sine wave, 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 o ...

Heilmann Locomotive
The Heilmann locomotives were a series of three experimental steam-electric locomotives produced in the 1890s for the French Chemins de Fer de l'Ouest (CF de l'Ouest). A prototype was built in 1894 and two larger locomotives were built in 1897. These locomotives used electric transmission, much like later-popular diesel-electric locomotives and various other self powered locomotives. La Fusée Electrique In 1890 registered a patent (France №. 207055) for a self powered electric vehicle; the design was intended to eliminate the unbalanced oscillatory moments and "hammer blow" caused by the cranked action of a conventional mechanical steam locomotive. His design used a balanced steam engine to drive the locomotive via an electrical transmission (an electrical generator driving electric motors via controlling rheostats and switches). Heilmann wished to create a machine specifically suited for high-speed trains without the high costs of an electrified infrastructure. His earliest ...

Electric Steam Boiler
An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals. Although they are more expensive to run than gas-fired or oil-fired boilers they are popular because of their simplicity and ease of use. Because of the large currents required, they are normally run from a three-phase electricity supply. They convert electrical energy into thermal energy with almost 100% efficiency but the overall thermal efficiency is variable, depending on the efficiency with which the electricity is generated. Making steam with an electric boiler The process of creating steam with an electric boiler is fairly simple. Electricity is run through a heating element that acts as a resistor to create heat through resistance. Water from the system or holding tank is then run ove ...

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 ...
