Mizens Railway
Mizens Railway is a 7¼ inch gauge miniature railway located in a 10-acre site near Woking in Surrey, England. The railway comprises three routes, the longest being nearly 1 mile long. A variety of locomotives are in use, including several steam engines. The railway was named after its original location at Mizens Farm, now the headquarters of McLaren until moving to the present site in 2000. Routes Three routes are operated by the railway on public running days, The Suburban, the Miler and the Highlander. A maximum of two of these routes can be operated at one time for the public. The Highlander saw its testing in mid-2014 with limited passenger runs. Technical difficulties prohibited opening in 2014 with final testing occurring in early 2015 before the start of the running season. Due to the demanding gradients of this route, it is only opened to the public in dry conditions and depending on the availability of locomotives and coaching stock. Trains on this route start and ...

South African Class A 4-8-2T
The South African Railways Class A 4-8-2T of 1888 was a steam locomotive from the pre-Union era in the Colony of Natal. In 1888, the Natal Government Railways placed the first five of its eventual one hundred Class D steam locomotives in service. The last was delivered in 1899. They were the first locomotives in the world to be built with a wheel arrangement, later to become known as the Mountain type. In 1912, when these locomotives were assimilated into the South African Railways, they were renumbered and designated Class A. In 1915, another two Class A locomotives were built from spare parts.South African Railways and Harbours Locomotive Diagram Book, 2'0" & 3'6" Gauge Steam Locomotives, 15 August 1941, as amended Manufacturers The Natal Government Railways (NGR) Class D tank locomotive was designed by William Milne, the Locomotive Superintendent of the NGR from 1877 to 1896, and was built by Dübs and Company.

Electric
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

Locomotives
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it 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 (see CargoSprinter). 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 a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first ...

British Rail Class 423
The British Rail Class 423 ( 4 VEP), electric multiple unit passenger trains were mostly built by British Rail (BR) at York Works from 1967 to 1974, although the MBSOs and TSOs of the first 20, 7701-7720, were built at Derby Works. They have manually opening doors next to every seating row and were the last coaching stock built in this pattern for BR. They were mostly found working outer-suburban services in South London and rural services in Kent, Sussex and Hampshire, up to 2005 when they were finally replaced by Electrostar and Desiro units. The fleet had a working life of 38 years. Description Standard units Ordered in 1965, 194 standard four-car 4 VEP units were built between 1967 and 1974, numbered 7701-7894; subsequently becoming class 423 under TOPS. They were subsequently renumbered in the 1980s into the 30xx and 31xx series in order to make numbers TOPS compliant. Between 1988 and 1995 the units were internally facelifted.

Miniature Railway
A ridable miniature railway (US: riding railroad or grand scale railroad) is a large scale, usually ground-level railway that hauls passengers using locomotives that are often models of full-sized railway locomotives (powered by diesel or petrol engines, live steam or electric motors). Overview Typically miniature railways have a rail track gauge between and under , though both larger and smaller gauges are used. At gauges of and less, the track is commonly raised above ground level. Flat cars are arranged with foot boards so that driver and passengers sit astride the track. The track is often multi-gauged, to accommodate , , and sometimes gauge locomotives. The smaller gauges of miniature railway track can also be portable and is generally / gauge on raised track or as / on ground level. Typically portable track is used to carry passengers at temporary events such as fêtes and summer fairs. Typically miniature lines are operated by not for profit organisations - often mod ...

Signal Box
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Station
A train station, railway station, railroad station or depot is a railway facility where trains stop to load or unload passengers, freight or both. It generally consists of at least one platform, one track and a station building providing such ancillary services as ticket sales, waiting rooms and baggage/freight service. If a station is on a single-track line, it often has a passing loop to facilitate traffic movements. Places at which passengers only occasionally board or leave a train, sometimes consisting of a short platform and a waiting shed but sometimes indicated by no more than a sign, are variously referred to as "stops", "flag stops", " halts", or "provisional stopping places". The stations themselves may be at ground level, underground or elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams or other rapid transit systems.
