CIE 421 Class
The Córas Iompair Éireann 421 Class was a railway locomotive, built by the CIÉ at Inchicore Works between 1962–1963 and designed for branch line traffic use and shunting. The 421 Class was a larger development of the earlier 401 Class, and were fitted with a Maybach MD220 engine of with diesel hydraulic transmission via a Mekydro KL64U transmission. Unlike the earlier E401 class, these locomotives were fitted for multiple operation. They were of C wheel arrangement. The first of the class made its debut in early October 1962 on pilot duties in the Dublin area and although they had a design maximum speed of , experience (notably the derailment of a trial train hauled by E421) showed that they did not ride well when travelling at speeds over and so henceforth were limited to that speed and used simply for shunting duties instead. They were numbered E421–E434, and were withdrawn from service between 1979 and 1983. Three of these locomotives have been preserved, as fol ...

CIÉ
Córas Iompair Éireann (''Irish Transport Company''), or CIÉ, is a statutory corporation of Ireland, answerable to the Irish Government and responsible for most public transport within the republic and jointly with its Northern Ireland counterpart, the Northern Ireland Transport Holding Company for the railway service between the Republic of Ireland and Northern Ireland. The company is headquartered at Heuston Station, Dublin. It is a statutory corporation whose members are appointed by the Minister for Transport. Services Since the enactment of the ''Transport (Re-organisation of Córas Iompair Éireann) Act, 1986'' CIÉ has been the holding company for Bus Éireann, Dublin Bus and Iarnród Éireann/Irish Rail, the three largest internal transport companies in Ireland. It was originally to have operated the Luas tram system in Dublin, but that project was transferred to the newly created Railway Procurement Agency. CIÉ's services are provided through three operating com ...

UIC Classification
The UIC classification of locomotive axle arrangements, sometimes known as the German classification''The Railway Data File''. Leicester: Silverdale, 2000. p. 52. . or German system,Kalla-Bishop P.M. & Greggio, Luciano, ''Steam Locomotives'', Crescent, 1985, p. 226. describes the wheel arrangement of locomotives, multiple units and trams. It is used in much of the world, notable exceptions being the United Kingdom, which uses a slightly simplified form of UIC (except for steam locomotives and small diesel shunters, where Whyte notation is used), and in North America, where the AAR wheel arrangement system (essentially another simplification of the UIC system) is used to describe diesel and electric locomotives; Whyte notation is used in North America only for steam locomotives. The classification system is managed by the International Union of Railways (UIC). Structure The UIC uses the following structure: ; Upper-case letters : Indicate driving axles, starting at A for a singl ...

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 ...

Diesel-hydraulic Locomotives
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 quic ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ...

Downpatrick And County Down Railway
The Downpatrick and County Down Railway (DCDR) is a five-foot, three-inch (1,600 mm) gauge heritage railway in County Down, Northern Ireland. It is operated by volunteers and runs passenger trains using steam and diesel locomotives, diesel railcars, and vintage carriages. The railway has approximately three miles (4.8 km) of track in a triangular-shaped layout, which connects the town of Downpatrick with the historical sites of Inch Abbey to the north and King Magnus’ Grave to the south. It also houses a museum of railway artefacts and rolling stock originating from both Northern Ireland and the Republic of Ireland, dating from the 1860s to the 1980s. The DCDR’s development was spearheaded by a group of local railway enthusiasts in the early 1980s, and work started on building the railway in 1985. Most of its track is on part of the now-closed Belfast and County Down Railway (BCDR) mainline which ran between Belfast, Downpatrick, and Newcastle. The heritage ra ...

Inchicore Railway Works
Inchicore railway works, also known locally as 'Inchicore' or 'The Works', was founded by the Great Southern and Western Railway in 1846 and emerged to become the major engineering centre for railways in Ireland. Located west of Dublin city centre, the works cover an area of approximately . The works are responsible for the overhaul, repair, servicing, spraying and washing of locomotives and rolling stock. In the past, the manufacture, assembly and rebuild of locomotives and rolling stock has been performed at Inchicore. History When the works was opened in 1846, there were a total of 39 employed at the facility. The locomotive erecting shop had 18 pits on one side and 16 on the other. By 1886, the works had expanded to 52 acres. In 1934 the erecting shop was replaced by a building with through roads. In 1976 the works employed over one thousand people and was 72 acres in size. Site The works are situated alongside and to the south of the Dublin to Cork main line about ...
