NCC Class X
The Northern Counties Committee (NCC) Class X was a solitary diesel-hydraulic shunting (switcher) locomotive built by Harland and Wolff (H&W) for service in the NCC's yards and at Belfast docks. It was one of several pioneering designs of diesel locomotive produced by H&W under their ''Harlandic'' trademark during the 1930s and 1940s. History There was only one member of Class X, No.17. It was built by Harland and Wolff in Belfast and delivered to the NCC in 1936 under a lease arrangement; it was not actually taken into stock until 1941 when the NCC purchased it. No.17 had an 0-6-0 wheel arrangement and was powered by an eight-cylinder diesel engine developing at 1200 rpm. Transmission was via a torque converter and a jackshaft final drive mounted ahead of the leading coupled wheels. In addition, there was a two-speed gearbox with ratios of 5.76:1 and 19.52:1 giving top speeds of and respectively in both forward and reverse. As delivered, it had its maker's trade name ''Harl ...

Diesel-hydraulic
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quick ...

Torque Converter
A torque converter is a type of fluid coupling that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. It is usually located between the engine's flexplate and the transmission. The equivalent location in a manual transmission would be the mechanical clutch. The main characteristic of a torque converter is its ability to increase torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear. This is a feature beyond that of the simple fluid coupling, which can match rotational speed but does not multiply torque and thus reduces power. Hydraulic systems By far the most common form of torque converter in automobile transmissions is the hydr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5 Ft 3 In Gauge Locomotives
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form 3p ...

C Locomotives
C, or c, is the third letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''. History "C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name ''gimel''. Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek ' Γ' (Gamma) was adopted into the Etruscan alphabet to represent . Already in the Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical Etru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jackshaft
A jackshaft, also called a ''countershaft'', is a common mechanical design component used to transfer or synchronize rotational force in a machine. A jackshaft is often just a short stub with supporting bearings on the ends and two pulleys, gears, or cranks attached to it. In general, a jackshaft is any shaft that is used as an intermediary transmitting power from a driving shaft to a driven shaft. History Jackshaft The oldest uses of the term ''jackshaft'' appear to involve shafts that were intermediate between water wheels or stationary steam engines and the line shafts of 19th century mills. In these early sources from New England mills in 1872 and 1880, the term ''"jack shaft"'' always appears in quotes. Another 1872 author wrote "Gear wheels are used in England to transmit the power of the engine to what is usually called the jack shaft."Coleman Sellers, Transmission of MotionJournal of the Franklin Institute Vol. LXIV, No. 5 (Nov. 1872); pages 305-319, ''countershaft'' i ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Ulster Transport Authority
The Ulster Transport Authority (UTA) ran rail and bus transport in Northern Ireland from 1948 until 1966. Formation and consolidation The UTA was formed by the Transport Act 1948, which merged the Northern Ireland Road Transport Board (NIRTB) and the Belfast and County Down Railway (BCDR). Added to this in 1949 was the Northern Counties Committee (NCC), owned by the British Transport Commission's Railway Executive since its previous owner, the London, Midland and Scottish Railway (LMS), had been nationalised in 1948. Branch railway closures In January 1950 the UTA closed almost the entire BCDR network except the Queen's Quay, Belfast – Bangor commuter line. In the same year it closed the Macfin – Kilrea section of the former NCC's Derry Central Railway and the freight-only former NCC line from Limavady to Dungiven. It also withdrew passenger services from the former NCC branch lines to Cookstown, Draperstown and Limavady and the Magherafelt – Kilrea section of th ...
