FS Class 671
The Rete Adriatica Class 500 (Italian: ''Gruppo 500''), classified after 1905 in the Ferrovie dello Stato Italiane (FS; Italian State Railways) as Class 670 (Italian: ''Gruppo 670'') was an unorthodox and iconic cab forward 4-6-0 (2'C) steam locomotive. Design and construction The Class 670 was designed by Eng. Giuseppe Zara of the Rete Adriatica (one of the two major railway companies in Italy at the beginning of the twentieth century); its design was very unorthodox, as the boiler was reversed on the frames, so that the cab and the firebox were leading and supported by the bogie, while the cylinders were at the rear. The compound arrangement was also highly peculiar, as it was the first experiment with the Plancher compound engine: this arrangement meant that there were four cylinders, in which the two high pressure (HP) ones and the two low pressure (LP) ones were paired together respectively on the left-hand and the right-hand side of the boiler, and each pair was served by ...

Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passenger Locomotives
A passenger (also abbreviated as pax) is a person who travels in a vehicle, but does not bear any responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle, and is not a steward. The vehicles may be bicycles, buses, passenger trains, airliners, ships, ferryboats, and other methods of transportation. Crew members (if any), as well as the driver or pilot of the vehicle, are usually not considered to be passengers. For example, a flight attendant on an airline would not be considered a passenger while on duty and the same with those working in the kitchen or restaurant on board a ship as well as cleaning staff, but an employee riding in a company car being driven by another person would be considered a passenger, even if the car was being driven on company business. Railways In railway parlance, passenger, as well as being the end user of a service, is also a categorisation of the type of rolling stock used.Simmo ...

Four-cylinder Compound Steam Locomotives
The engine configuration describes the fundamental operating principles by which internal combustion engines are categorized. Piston engines are often categorized by their cylinder layout, valves and camshafts. Wankel engines are often categorized by the number of rotors present. Gas turbine engines are often categorized into turbojets, turbofans, turboprops and turboshafts. Piston engines Piston engines are usually designed with the cylinders in lines parallel to the crankshaft. It is called a straight engine (or 'inline engine') when the cylinders arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat engines), each line of cylinders is referred to as a 'cylinder bank'. The angle between cylinder banks is called the 'bank angle'. Engines with multiple banks are shorter than straight engines and can be designed to cancel out the unbalanced forces from each bank, in order to reduce the vibration. Most engines with ...

Railway Locomotives Introduced In 1900
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breda Locomotives
Breda () is a city and municipality in the southern part of the Netherlands, located in the province of North Brabant. The name derived from ''brede Aa'' ('wide Aa' or 'broad Aa') and refers to the confluence of the rivers Mark and Aa. Breda has 185,072 inhabitants on 13 September 2022 and is part of the Brabantse Stedenrij; it is the ninth largest city/municipality in the country, and the third largest in North Brabant after Eindhoven and Tilburg. It is equidistant between Rotterdam and Antwerp. As a fortified city, it was of strategic military and political significance. Although a direct Fiefdom of the Holy Roman Emperor, the city obtained a municipal charter; the acquisition of Breda, through marriage, by the House of Nassau ensured that Breda would be at the centre of political and social life in the Low Countries. Breda had a population of in ; the metropolitan area had a population of . History In the 11th century, Breda was a direct fief of the Holy Roman Emperor, it ...

Franco-Crosti Boiler
The Franco–Crosti boiler is a type of boiler used for steam locomotives. It was designed in the 1930s by Attilio Franco and Dr Piero Crosti. The main difference between it and conventional feedwater heaters widely used on the continent is that the Franco-Crosti boiler uses both exhaust steam and exhaust gases from the firebox. Conventional feedwater heaters only use exhaust steam. Purpose The Franco–Crosti boiler is a modification of the conventional fire tube boiler design used on most steam locomotives. Unlike conventional boilers the heat remaining in the exhaust gases is used to preheat the water supply for the main boiler using a secondary heat exchange mechanism. This mechanism, known as the ''feedwater heater'' is essentially a secondary boiler. The preheated feedwater is fed at full boiler pressure into the main boiler via clack valves. The feedwater heater is not designed to produce steam, instead raising the temperature of the feedwater. This allows the heater to ...
