Tank Locomotives
A tank locomotive is a steam locomotive which carries its water in one or more on-board water tanks, instead of a more traditional tender (rail), tender. Most tank engines also have Fuel bunker, bunkers (or fuel tanks) to hold fuel; in a #Tender-tank, tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for Shunting (rail), shunting and shorter-distance Main line (railway), main line duties. Tank locomotives have #Advantages and disadvantages, advantages and disadvantages compared to traditional locomotives that required a separate tender to carry needed water and fuel.

LBSCR J1 Class
The London, Brighton and South Coast Railway (LB&SCR (known also as the Brighton line, the Brighton Railway or the Brighton)) was a railway company in the United Kingdom from 1846 to 1922. Its territory formed a rough triangle, with London at its apex, practically the whole coastline of Sussex as its base, covering a large part of Surrey. It was bounded on its western side by the London and South Western Railway (L&SWR), which provided an alternative route to Portsmouth. On its eastern side the LB&SCR was bounded by the South Eastern Railway (England), South Eastern Railway (SER)—later one component of the South Eastern and Chatham Railway (SE&CR)—which provided an alternative route to Bexhill-on-Sea, Bexhill, St Leonards-on-Sea, and Hastings. The LB&SCR had the most direct routes from London to the south coast seaside resorts of Brighton, Eastbourne, Worthing, Littlehampton and Bognor Regis, and to the ports of Newhaven, East Sussex, Newhaven and Shoreham-by-Sea. It served ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Fairbairn & Sons
William Fairbairn and Sons, was an engineering works in Manchester, England. History William Fairbairn opened an iron foundry in 1816 and was joined the following year by a Mr. Lillie, and the firm became known as Fairbairn and Lillie Engine Makers, producing iron steamboats. Their foundry and millwrighting factory burned down on 6 August 1831 with damage estimated at £8,000. The business survived this event. Shipbuilding In 1830, they built the iron paddle-steamer ''Lord Dundas'', for use on the Forth and Clyde Canal. She proved so successful that the firm built eight more of a larger size within the next two or three years for Scottish canals, two passenger-boats with 40 horsepower engines for the Humber and two for the lakes of Zurich and Walenstadt in Switzerland, which, after being tried, were sent out dismantled.

Hunslet Engine Company
The Hunslet Engine Company is a locomotive building company, founded in 1864 in Hunslet, England. It manufactured steam locomotives for over 100 years and currently manufactures Diesel engine, diesel Switcher, shunting locomotives. The company owns a substantial fleet of Industrial and depot shunting locomotives which are available for hire. The company is part of Ed Murray & Sons Ltd. History The early years 1864–1901 The company was founded in 1864 at Jack Lane in Hunslet by John Towlerton Leather, a civil engineering contractor, who appointed James Campbell (son of Alexander Campbell, a Leeds engineer) as his works manager. The first engine was completed in 1865. It was ''Linden'', a standard gauge delivered to Thomas Brassey, Brassey and Ballard, a railway civil engineering contractor as were several of the firm's early customers. Other customers included collieries. This basic standard gauge shunting and short haul "industrial" engine was to be the main-stay of Huns ...

Smokebox
A smokebox is one of the major basic parts of a steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney (or funnel). Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two specific reasons. Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox. Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day. Without a smokebox, all char m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round-topped Boiler
A round-topped boiler is a type of steam boiler, boiler used for some designs of steam locomotive and portable engine. It was an early form of :en:locomotive boiler, locomotive boiler, although continuing to be used for new locomotives through to the end of steam locomotive manufacture in the 1960s. Firebox They use the early form of firebox (steam engine), firebox, where the outer wrapper of the firebox (steam engine), firebox is a semi-circular continuation of the cylindrical boiler barrel. They are relatively simple in shape and manufacture, but their design and service is complicated by the difference in shape between the outer and the flat-topped inner wrapper of the firebox. This requires complex Boiler stay, staying to support it. The first boilers of this form had raised fireboxes that were considerably larger, particularly higher, than the boiler barrel. In the extreme case, this gave rise to the haycock boiler, where the firebox was raised into a vaulted dome. In most c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belpaire Firebox
The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today it generally refers to the shape of the outer shell of the firebox which is approximately flat at the top and square in cross-section, indicated by the longitudinal ridges on the top sides. However, it is the similar square cross-section inner firebox which provides the main advantages of this design i.e. it has a greater surface area at the top of the firebox where the heat is greatest, improving heat transfer and steam production, compared with a round-top shape. The flat firebox top would make supporting it against pressure more difficult (e.g. by means of girders, or stays) compared to a round-top. However, the use of a similarly shaped square outer boiler shell allows simpler perpendicular stays to be used between the shells. The Belpaire outer firebox is, nevertheless, more complicated and expensive to manufacture than a round-top version. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ogee
An ogee ( ) is an object, element, or curve—often seen in architecture and building trades—that has a serpentine- or extended S-shape (Sigmoid curve, sigmoid). Ogees consist of a "double curve", the combination of two semicircle, semicircular curves or arc (geometry), arcs that, as a result of a inflection point, point of inflection from concave function, concave to convex function, convex or ''vice versa'', have ends of the overall curve that point in opposite directions (and have tangents that are approximately parallel). First seen in textiles in the 12th century, the use of ogee elements—in particular, in the design of arches—has been said to characterise various Gothic architecture, Gothic and Gothic Revival architecture, Gothic Revival architectural styles. The shape has many such uses in architecture from those periods to the present day, including in the ogee arch in these architectural styles, where two ogees oriented as mirror images compose the sides of the ar ...

Saddle
A saddle is a supportive structure for a rider of an animal, fastened to an animal's back by a girth. The most common type is equestrian. However, specialized saddles have been created for oxen, camels and other animals. It is not known precisely when riders first began to use some sort of padding or protection, but a blanket attached by some form of surcingle or girth was probably the first "saddle", followed later by more elaborate padded designs. The solid saddle tree was a later invention, and though early stirrup designs predated the invention of the solid tree, the paired stirrup, which attached to the tree, was the last element of the saddle to reach the basic form that is still used today. Present-day saddles come in a wide variety of styles, each designed for a specific equestrianism discipline, and require careful fit to both the rider and the horse. Proper saddle care can extend the useful life of a saddle, often for decades. The saddle was a crucial step in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valve Gear
The valve gear of a steam engine is the mechanism that operates the inlet and exhaust valves to admit steam into the cylinder and allow exhaust steam to escape, respectively, at the correct points in the cycle. It can also serve as a reversing gear. It is sometimes referred to as the "motion". Purpose In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure, minus transmission losses, against the piston throughout the stroke) while peak efficiency is achieved by only having the inlet valve open for a short time and then letting the steam expand in the cylinder (expansive working). The point at which steam stops being admitted to the cylinder is known as the '' cutoff'', and the optimal posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive Boiler
A fire-tube boiler is a type of boiler invented in 1828 by Marc Seguin, Marc Seguin, in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack boiler, haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume. The general construction is as a tank of water penetrated by tubes that carry the hot flue gases from the fire. The tank is usually Cylinder (geometry), cylindrical for the most part—being the strongest practical shape for a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
