British Rail D0260
D0260, named ''Lion'', was a prototype Type 4 mainline diesel-electric locomotive built in 1962 by a consortium of Birmingham Railway Carriage and Wagon Company, Sulzer the engine maker and Associated Electrical Industries, at BRCW's Smethwick works near Birmingham. The locomotive's number was derived from its works number, DEL260. Specification ''Lion'' was a private venture to meet a requirement from British Railways for a powerful locomotive of Co-Co wheel arrangement, as a substitute for the earlier 1Co-Co1 locomotives such as the ''Peak'' classes. The specifications were revealed by the British Transport Commission (BTC) at a meeting on 15 January 1960. Train heating was to be by both steam and electric train heating (ETH). Unlike the earlier Pilot Scheme, the BTC expected that these prototypes would be funded by the makers, rather than bulk orders being placed sight-unseen. For the Type 4, that gave rise to three prototypes: ''Falcon'', DP2 and ''Lion'', the latter tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birmingham Railway Carriage And Wagon Company
The Birmingham Railway Carriage and Wagon Company (BRC&W) was a railway locomotive and carriage builder, founded in Birmingham, England and, for most of its existence, located at nearby Smethwick, with the factory divided by the boundary between the two places. The company was established in 1854. Production BRC&W made not only carriages and wagons, but a range of vehicles, from aeroplanes and military gliders to buses, trolleybuses and tanks. Nevertheless, it is as a builder of railway rolling stock that the company is best remembered, exporting to most parts of the new and old worlds. It supplied vehicles to all four of the pre-nationalisation "big four" railway companies (London, Midland and Scottish Railway, LMS, Southern Railway (UK), SR, London and North Eastern Railway, LNER and Great Western Railway, GWR), British Rail, Pullman Company, Pullman (some of which are still in use) and Compagnie Internationale des Wagons-Lits, Wagons-Lits, plus overseas railways with dive ...

British Rail Class 50
The British Rail Class 50 is a class of diesel locomotives designed to haul express passenger trains at . Built by English Electric at the Vulcan Foundry in Newton-le-Willows between 1967 and 1968, the Class 50s were initially on a 10-year lease from English Electric Leasing, and were employed hauling express passenger trains on the then non-electrified section of the West Coast Main Line between Crewe railway station, Crewe and Scotland. Initially numbered D400–D449 and known as English Electric Type 4s, the locomotives were purchased outright by British Rail (BR) at the end of the lease and became Class 50 in the TOPS renumbering of 1973. The class gained the nickname "Hoovers" because of the noise made by the clean air plant at the No. 2 end, prior to refurbishment, which was likened to that of a vacuum cleaner, a name believed given to them by the staff at Paddington Station. Once the electrification from Crewe to Glasgow was completed the locomotives were moved to the Grea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibreglass
Fiberglass (American English) or fibreglass ( Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non- conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Generator (railroad)
A steam generator is a type of boiler (steam generator), boiler used to produce steam for climate control and potable water heating in railroad Passenger car (rail), passenger cars. The output of a railroad steam generator is low-pressure, saturated steam that is passed through a system of water pipe, pipes and Water pipe, conduits throughout the length of the train. Steam generators were developed when diesel locomotives started to replace steam locomotives on passenger trains. In most cases, each passenger locomotive was fitted with a steam generator and a feedwater supply tank. The steam generator used some of the locomotive's diesel fuel supply for combustion. When a steam-generator–equipped locomotive was not available for a run, a so-called "heating car" fitted with one or two steam generators was inserted between the last locomotive in the consist and the rest of the train. Steam generators would also be fitted to individual cars to enable them to be heated independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vierendeel Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A ''two-force member'' is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, architectural trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as ...

Pratt Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin-jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with the strength to mainta ...

Cant (road/rail)
The cant of a Rail transport, railway track or camber angle, camber of a road (also referred to as superelevation, cross slope or cross fall) is the rate of change in elevation (height) between the two rails or edges of the road. This is normally greater where the railway or road is curved; raising the outer rail or the outer edge of the road creates a banked turn, thus allowing vehicles to travel round the curve at greater speeds than would be possible if the surface were level. Rail Superelevation in railway tracks ;Importance of superelevation In curved railway tracks, the outer rail is elevated, providing a banked turn. This allows trains to navigate curves at higher speeds and reduces the pressure of the wheel flanges against the rails, minimizing friction and wear. The difference in elevation between the outer and inner rails is referred to as cant in most countries. ;How superelevation works The main functions of cant are the following: * Improve distribution of th ...

BR Class 45
The British Rail Class 45 or Sulzer Type 4 are diesel locomotives built by British Railways' Derby and Crewe Works between 1960 and 1962. Along with the similar Class 44 and 46 locomotives, they became known as ''Peaks''. Technical details Engine The engine of the Class 45 was a marine-type, slow-revving diesel, a Sulzer 12LDA28B with a bore of (hence the 28 in the engine designation) and a stroke of . This gave per cylinder, or for the whole engine. The unit was turbocharged and intercooled and gave at 750 rpm. The engine was of the double bank type with two parallel banks of 6 cylinders, geared together to a single output shaft. Six-cylinder versions of the engine were fitted in the Class 25 locos (amongst others) and eight-cylinder versions in Class 33s. Class 45s were the updated versions of the Class 44 locomotives, the latter having a non-intercooled version of the same engine; i.e. the 12LDA28A. The later Class 47 had a modified version of the same ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Sulzer Diesel Engines
This article covers the History of Sulzer diesel engines from 1898 to 1997. Sulzer Brothers foundry was established in Winterthur, Switzerland, in 1834 by Johann Jakob Sulzer-Neuffert and his two sons, Johann Jakob and Salomon. Products included cast iron, firefighting pumps and textile machinery. Rudolf Diesel was educated in Augsburg and Munich and his works training was with Sulzer, and his later co-operation with Sulzer led to the construction of the first Sulzer diesel engine in 1898. In 2015, the Sulzer (manufacturer), Sulzer company lives on but it no longer manufactures diesel engines, having sold the diesel engine business to Wärtsilä in 1997. Overview Sulzer built diesel engines for stationary, road, rail and marine use. The engine types usually comprise a number, then some letters, then another number. For example, 6LDA28 indicates a six-cylinder engine in the "LDA" series with a 28 cm cylinder bore. Road In 1937, Sulzer introduced an opposed piston two-stroke di ...

U Engine
A U engine is a piston engine made up of two separate straight engines (complete with separate crankshafts) placed side-by-side and coupled to a shared output shaft. When viewed from the front, the engine block resembles the letter "U". Although much less common than the similar V engine design, several U engines were produced from 1915 to 1987 for use in airplanes, racing cars, racing and road motorcycles, locomotives, and tanks. Design The main benefit of a U engine layout is the ability to share common parts with a straight engine upon which is it based. Additionally, if the two crankshafts rotate in opposite directions, the gyroscopic effect of the rotating components in each cylinder bank cancel each other out. A V engine is typically more compact and lighter than a U engine, in part due to the lack of a second crankshaft, making V engines far more common than U engines. However, the V engine does not cancel the gyroscopic effect. The H engine layout uses a similar con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
