Diesel Locomotive
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 ...

Rail Transport In Great Britain
The railway system in Great Britain is the oldest railway system in the world. The first locomotive-hauled public railway opened in 1825, which was followed by an era of rapid expansion. Most of the track is managed by Network Rail, which in 2017 had a network of of standard-gauge lines, of which were electrified. These lines range from single to quadruple track or more. In addition, some cities have separate metro, light rail and tram systems (including the extensive and historic London Underground). There are also many private railways (some of them narrow-gauge), which are primarily short lines for tourists. The main rail network is connected with that of continental Europe by the Channel Tunnel and High Speed 1 (originally the Channel Tunnel Rail Link), which fully opened in 1994 and 2007 respectively. In 2019, there were 1.738 billion journeys on the National Rail network, making the British network the fifth most used in the world (Great Britain ranks 23rd in ...

TOPS
Total Operations Processing System (TOPS) is a computer system for managing railway locomotives and rolling stock, known for many years of use in the United Kingdom. TOPS was originally developed between the Southern Pacific Railroad (SP), Stanford University and IBM as a replacement for paper-based systems for managing rail logistics. A jointly-owned consultancy company, ''TOPS On-Line Inc.'', was established in 1960 with the goal of implementing TOPS, as well as selling it to third parties. Development was protracted, requiring around 660 man-years of effort to produce a releasable build. During mid-1968, the first phase of the system was introduced on the SP, and quickly proved its advantages over the traditional methods practiced prior to its availability. In addition to SP, TOPS was widely adopted throughout North America and beyond. While it was at one point in widespread use across many of the United States railroads, the system has been perhaps most prominently used ...

British Rail Class 21 (NBL)
The British Rail Class 21 was a type of Type 2 diesel-electric locomotive built by the North British Locomotive Company in Glasgow for British Rail in 1958–1960. They were numbered D6100-D6157. Thirty-eight of the locomotives were withdrawn by August 1968; the rest were rebuilt with bigger engines to become Class 29, although those locos only lasted until 1971. Description Under the British Railways Modernisation Plan, a batch of ten diesel-electric locomotives were ordered from the North British Locomotive Co. for evaluation under BR's dieselisation pilot scheme. At the same time, six externally similar locomotives with hydraulic transmission were ordered for comparison, these becoming Class 22. Repeat orders resulted in a total of 58 of the diesel-electric locomotives being built (numbered D6100–6157). They were delivered between December 1958 and November 1960. Operation Eastern Region The first 38 locomotives entered service in 1958-59 from the Eastern Region dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North British Locomotive Company
The North British Locomotive Company (NBL, NB Loco or North British) was created in 1903 through the merger of three Glasgow locomotive manufacturing companies; Sharp, Stewart and Company (Atlas Works), Neilson, Reid and Company (Hyde Park Works) and Dübs and Company (Queens Park Works), creating the largest locomotive manufacturing company in Europe and the British Empire. Its main factories were located at the neighbouring Atlas and Hyde Park Works in central Springburn, as well as the Queens Park Works in Polmadie. A new central Administration and Drawing Office for the combined company was completed across the road from the Hyde Park Works on Flemington Street by James Miller in 1909, later sold to Glasgow Corporation in 1961 to become the main campus of North Glasgow College (now Glasgow Kelvin College). The two other Railway works in Springburn were St. Rollox railway works, owned by the Caledonian Railway and Cowlairs railway works, owned by the North British Railway ...

British Rail Class 21 (MaK)
The second use of the TOPS classification Class 21 for locomotives used on the British railway network came through the use of a number of related diesel-hydraulic and diesel-electric locomotives procured following the opening of the Channel Tunnel. The total of 16 locomotives were obtained by two separate operators, with some used for freight, and others to propel service trains and as "Thunderbird" locomotives. History In the early 1980s, Maschinenbau Kiel introduced its MaK DE 1002 design of diesel-electric locomotive, which was chosen by Nederlandse Spoorwegen as the basis of its Class 6400 freight locomotive. In 1991, Eurotunnel procured five similar locomotives as its Class 0001, for use both to operate service trains through the Channel Tunnel and as rescue locomotives. In 2005, Euro Cargo Rail (ECR) was formed as a freight operator in France by English, Welsh and Scottish Railway (EWS). Its initial operations were carried out by a quartet of Vossloh G1206 diesel-hydr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maschinenbau Kiel
Maschinenbau Kiel GmbH designed, manufactured and marketed marine diesel engines, diesel locomotives and tracked vehicles under the MaK brand name. The three primary operating divisions of Maschinenbau Kiel GmbH were sold to different companies in the 1990s. Rheinmetall acquired the military vehicles division in 1990. Siemens acquired the locomotive manufacturing division in 1992. Siemens sold the locomotive division to the current owner, Vossloh, in 1998. Caterpillar Inc. acquired the marine diesel engine division in 1997. Both Vossloh and the marine diesel engine division of Caterpillar are still based in Kiel. Caterpillar continues to use MaK brand name on their products. The companies are major employers in Kiel. History Origins The companies origins can be traced back at least as far as 1918. With the Treaty of Versailles limiting arms production in Germany, the defence based industries in Kiel sought other markets. Kiel Deutsche Werke AG (DWK) was founded; producing ...
