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. By the outbreak of the Second World War, of SBB lines (73.6% of the network) had been Railway electrification system, electrified, whilst the price of imported German coal kept rising. In an attempt to save on coal the Swiss Federal Railways fitted two sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steam Turbine Locomotive
A steam turbine locomotive was a steam locomotive which transmitted 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 to both 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 ...

List Of Steam Technology Patents
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

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 No.. 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 ...

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 over or ...

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 (electricity), battery or a supercapacitor. Locomotives with on-board fuelled prime mover (locomotive), prime movers, such as diesel engines or gas turbines, are classed as Diesel–electric powertrain, diesel–electric or turbine–electric powertrain, gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a Transmission (mechanics), 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 loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1980–2015
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Hornby Railways
Hornby Hobbies Limited is a British-owned scale model manufacturing company which has been focused on rail transport modelling, model railways. Its roots date back to 1901 in Liverpool, when founder Frank Hornby received a patent for his Meccano construction toy. The first clockwork train was produced in 1920. In 1938, Hornby launched its first OO gauge train. In 1964, Hornby and Meccano were bought by their competitor, Tri-ang Railways, and sold when Tri-ang went into receivership. Hornby Railways became independent again in the 1980s, and became listed on the London Stock Exchange, but due to financial troubles reported in June 2017, became majority owned by British turnaround specialist Phoenix Asset Management. Hornby Hobbies bought model paint manufacturer Humbrol and their scale model kit subsidiary Airfix in 2007. The die-cast model car brand Corgi Toys, Corgi was added in 2008. Hornby's other brands include for model railways Bassett-Lowke, Jouef, Lima (models), Lima, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brienz–Rothorn Railway
The Brienz Rothorn Railway (, BRB) is a tourist rack railway in Switzerland, which climbs from Brienz, at the eastern end of Lake Brienz, to the summit of the Brienzer Rothorn. The railway is 7.6 kilometres (4.7 mi) long, is built to 800 mm gauge ( gauge), and uses the Abt double lamella rack system. Unusually for Switzerland, the line is not electrified, and most trains are operated by steam locomotives. The Brienz Rothorn Railway reaches a height of above sea level and is the fourth-highest railway in Switzerland.After the Jungfrau, Gornergrat, and Bernina railway History The railway was opened on 17 June 1892, after a two years construction period. The two designers, engineer Alexander Lindner and contractor Theo Bertschinger were supported by the mountain railway pioneer Roman Abt, who had responsibility for equipping the line with his newly developed Abt double lamella rack system. The line connected at Brienz with the Brünig railway line, which had bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
