IE 201 Class
The Iarnród Éireann (IÉ) / Northern Ireland Railways 201 Class locomotives are the newest and most powerful diesel locomotives operating in Ireland and were built between 1994 and 1995 by General Motors Diesel. They are model type JT42HCW, fitted with an EMD 12-710G3B engine of , weigh and have a maximum speed of . A freight version, the EMD Series 66, with the same engine, is used on privately operated European mainline freight duties. History By the early 1990s the locomotives operating passenger services in Ireland were becoming increasingly obsolete, with the newest type in service being the 071 Class introduced in 1976. The economic boom in Ireland in the mid-1990s allowed Iarnród Éireann to begin significant investment in the infrastructure of the railways, which began with an order for 32 brand new express locomotives from GM-EMD. Northern Ireland Railways also purchased 2. The first were delivered in 1994, with deliveries continuing until 1995. To allow clearance ...

General Motors Diesel
General Motors Diesel was a railway diesel locomotive manufacturer located in London, Ontario, Canada. It was established in 1949 as the Canadian subsidiary of the Electro-Motive Diesel division of General Motors (EMD). In 1969 it was re-organized as the "Diesel Division of General Motors of Canada, Ltd." The plant was re-purposed to include manufacture of other diesel-powered General Motors vehicles such as buses. Following the Canada-United States Free Trade Agreement in 1989, all of EMD's locomotives were built at the London facility. In 2005 new owners of EMD renamed the Canadian subsidiary "Electro-Motive Canada". The plant was closed by EMD's new owner Progress Rail in 2012, with EMD's production remaining in LaGrange, Illinois and Muncie, Indiana. History Early diesel locomotive manufacturing in Canada Diesel-electric locomotives were built in Canada beginning in 1928. The earliest diesels were custom built one-of-a-kind designs such as Canadian Nationals numbers 9000 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Driving Van Trailer
A Driving Van Trailer (DVT) is a Great Britain, British purpose-built control car railway vehicle that allows the driver to operate with a locomotive in Push-pull train, push-pull formation from the opposite end of a train. A key benefit of operating trains with DVTs is the requirement for fewer locomotives; for example, a second locomotive would otherwise have to join at the other end of the train after arrival at terminal stations to lead the train's onward journey. Unlike many other control cars, DVTs resemble locomotives, specifically British Rail Class 90, Class 90 for the 82/1 mark 3 series and British Rail Class 91, Class 91 for the 82/2 mark 4 series; thus when the train is operating in push mode, it does not appear to be travelling backwards. The vehicles do not have any passenger accommodation due to health and safety rules in place at the time of construction that prohibited passengers in the leading carriages of trains that run faster than .

Mark 4 (Iarnród Éireann)
The CAF Mark 4 (or MK4 or MKIV) are Passenger car (rail), railway carriages operated by Iarnród Éireann in Republic of Ireland, Ireland on the InterCity (Iarnród Éireann), InterCity service from Dublin to Cork. These carriages have no connection to the British Rail Mark 4. History Along with the occasional Cravens stocked train, the Dublin–Cork railway line, Dublin to Cork express was operated only with outdated slam-door British Rail Mark 2s and electric-door British Rail Mark 3, Mark 3s. Since only a limited amount of Mark 3 Driving Van Trailer, DVTs were available most services required a locomotive shunt at the end of each trip. This resulted in an infrequent service with most services bunched in the morning and evening rush hours. Iarnród Éireann opted to extend the service to an hourly clockface departure in order to increase growth on the line. Initially, to eliminate the Locomotive shunt, interest was expressed in a long range diesel multiple unit however, since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterprise (train Service)
''Enterprise'' is the cross-border inter-city train service between in the Republic of Ireland and in Northern Ireland, jointly operated by Iarnród Éireann (IE) and NI Railways (NIR). It operates on the Belfast–Dublin railway line. History The Great Northern Railway (Ireland) (GNR(I)) introduced the service as the "Enterprise Express" on Monday 11 August 1947 in an attempt to compete with air and road transport which were challenging the railways. In particular, business travel was and is an important market. Customs checks were limited to the Belfast and Dublin terminals to reduce journey times by ensuring that journeys were non-stop, and advance booking was available. The name of the train comes from the "enterprising" approach that the GNR(I) took to make journeys more convenient for passengers despite the requirement for customs checks. The initial service ran between and Dublin Amiens Street Junction (renamed in 1966). Locomotives of GNRI Class V were initially ...

Head End Power
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive (or a generator car) at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs. The maritime equivalent is hotel electric power. A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger cars on the London to Brighton route heralded the beginning of using electricity to light trains in the world. History Oil lamps were introduced in 1842 to light trains. Economics drove the Lancashire and Yorkshire Railway to replace oil with coal gas lighting in 1870, but a gas cylinder explosion on the train led them to abandon the experiment. Oil-gas lighting was introduced in late 1870. Electrical lighting was introduced in October 1881 by using twelve Swan carbon filament incandescent lamps c ...

CIE 201 Class
The Córas Iompair Éireann 201 Class was a class of 34 diesel electric locomotives manufactured by Metropolitan-Vickers at their Dukinfield Works in Manchester. They were a smaller, lighter and less powerful version of the 001 Class and were originally intended for branch line passenger and freight (mixed traffic) duties. They were introduced in 1956 and, although their duties changed over the years, were in regular service on the Irish railway network until the mid-1980s. Six were sold to Northern Ireland Railways (NIR) in 1986. Service history Unfortunately, these locomotives suffered from two distinct problems: * During the late 1950s and early 1960s, following the publication of the Andrews Report (mimicking the widescale the Beeching Axe in Britain), CIÉ undertook large-scale closures of branch lines, leaving the engines without a purpose. *The locomotives were of insufficient power for their duties and their Crossley engines suffered reliability problems.

CIE 001 Class
The Córas Iompair Éireann 001 Class locomotive was manufactured by Metropolitan-Vickers at their Dukinfield Works in Manchester. The 001 Class locomotive was the backbone of mainline passenger and freight train services on the Irish railway network for forty years from 1955 until the mid-1990s when they were replaced by the new 201 Class. Engines Crossley Initially they were fitted with eight-cylinder two-stroke, port-controlled Crossley engines. These were a loop scavenge type, which utilised a patented principle that recycled the normally wasted exhaust-pressure pulse to boost charge air in the cylinder. They produced at 625 rpm and could do . The original sandboxes, which were used to improve traction with the rail, were removed after a few years. Their Crossley engines proved to be notoriously unreliable from the start. Amongst a plethora of problems were: * Unbalanced engines resulting in vibration-induced fuel pipe and water pipe fractures * Cylinder defects * ...

Metropolitan-Vickers
Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metropolitan-Vickers F.2. Its factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world. History Metrovick started as a way to separate the existing British Westinghouse Electrical and Manufacturing Company factories from United States control, which had proven to be a hindrance to gaining government contracts during the First World War. In 1917 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Noise Control
Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in commercial airline headsets with the technology becoming available in the late 1980s. The technology is also used in road vehicles, mobile telephones, earbuds, and headphones Explanation Sound is a pressure wave, which consists of alternating periods of compression and rarefaction. A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) relative to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference. Modern active noise control is generally achiev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
