Mineral Locomotive
A drag freight is a long, slow, high-tonnage railroad train, often carrying commodities such as coal or ore. Compared to "fast freight" trains, drag freight trains have a very low power-to-weight ratio, making them somewhat unpredictable on steep grades or hilly routes. This causes many dispatchers to be extremely conservative with how they handle drag freights, especially when they share lines with higher priority fast freights and passenger trains. Power Before and during WWI and into the 1920s, large locomotives such as the 2-8-2 Mikado or mainly larger types like articulated locomotives or larger rigid-frame wheel arrangements such as the 2-10-4 Texas were typically used for drag freight operations. After the railroads dieselized, heavy duty diesel locomotives (typically six-axle units, to improve adhesion) were used for the drag freights. Multiple unit operations allowed one person to control multiple locomotives. As many as 4 to 11 locomotives may be used for a heavy ha ...

1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD70MAC
The EMD SD70 is a series of diesel-electric locomotives produced by the US company Electro-Motive Diesel. This locomotive family is an extension and improvement of the EMD SD60 series. Production commenced in late 1992 and since then over 5,700 units have been produced; most of these are the SD70M, SD70MAC, and SD70ACe models. While the majority of the production was ordered for use in North America, various models of the series have been used worldwide. All locomotives of this series are hood units with C-C trucks, except the SD70ACe-P4 and SD70MACH which have a B1-1B wheel configuration, and the SD70ACe-BB, which has a B+B-B+B wheel arrangement. Superseding the HT-C truck, a new bolsterless radial HTCR truck was fitted to all EMD SD70s built 1992–2002; in 2003 the non-radial HTSC truck (basically the HTCR made less costly by removing radial components) was made standard on the SD70ACe and SD70M-2 models; the radial HTCR truck remained available as an option.

Freightliner Group
Freightliner Group is a rail freight and logistics company headquartered in the United Kingdom. It is owned by Brookfield Corporation, Brookfield, a Canadian investment management company and GIC (sovereign wealth fund), GIC, a Singaporean sovereign wealth fund. It was originally created after the Transport Act 1968 as Freightliner Limited, a British government-owned company. From its onset, Freightliner was focused on the haulage of international traffic, thus came to centre its activities around Britain's sea ports, often building new multimodal freight depots adjacent to such locations to better capture this business. During the late 1970s, it was reorganised under British Rail, and became a part of its Railfreight Distribution subsidiary during the late 1980s. Work to expand the loading gauge on routes such as the East Coast Main Line were undertaken, allowing trains hauling larger containers to be routes, were conducted around this time. Numerous domestic depots previously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DB Cargo UK
DB Cargo UK (formerly DB Schenker Rail UK and English, Welsh & Scottish Railway) is a British rail freight company owned by Deutsche Bahn and headquartered in Doncaster, England. The company was established by Wisconsin Central Ltd., Wisconsin Central in early 1995 as ''North & South Railways'', successfully acquiring and merging five of the six freight companies that were sold during the privatisation of British Rail.The sixth rail freight company created during privatisation, Freightliner Group, Freightliner, was privatised through a management buyout. On 25 April 1996, the English, Welsh & Scottish EWS brand was revealed and implemented over successive months. By the end of March 1997, it controlled 90% of the UK rail freight market, operated a fleet of 900 locomotives and 19,000 wagons, and had 7,000 employees. During the late 1990s, EWS invested heavily into rolling stock renewal, procuring a large number of British Rail Class 66 diesel locomotives. EWS reduced staff number ...

British Rail Class 66
The British Rail Class 66 is a type of six-axle diesel-electric freight locomotive developed in part from the , for use on UK railways. Since its introduction the class has been successful and has been sold to British and other European railway companies. In Continental Europe it is marketed as the EMD Class 66 (JT42CWR). History Background On the privatisation of British Rail's freight operations in 1996, Wisconsin Central Transportation Systems under the control of Ed Burkhardt bought a number of the newly privatised rail freight companies: Transrail Freight, Mainline Freight, Loadhaul, and later, Railfreight Distribution and Rail Express Systems; thus controlling 93% of UK rail freight. After a public relations exercise involving the input of the general public, the company was named English Welsh & Scottish Railway (EWS). EWS inherited a fleet of 1,600, mainly diesel, locomotives, with an average age of over 30 years; 300 had been cannibalised for spares. Typical o ...

British Rail Class 60
The British Rail Class 60 is a class of Co-Co locomotives, Co-Co heavy freight diesel-electric locomotives built by Brush Traction. They are nicknamed ''Tugs'' by rail enthusiasts. During the 1980s, it became increasingly apparent that British Rail required a more capable British Rail locomotive and multiple unit numbering and classification#1957 numbering and classification, Type 5 locomotive for its heavy freight trains. Dissatisfaction with the British Rail Class 56's reliability led to the stipulation of a 95 per cent availability, a stringent requirement at the time. A total of three bids were received to a competitive tender issued on 10 August 1987; of these, Brush Traction's submission was selected and an order for 100 locomotives was issued during the following year. Despite the first example being completed during June 1989, due to a number of technical issues discovered during testing, the first examples of the Class 60 would not enter revenue service until late 1990. ...

Brake (railway)
A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains. Early developments In the earliest days of railways, braking technology was primitive. The first trains had brakes operative on the locomotive tender and on vehicles in the train, where "porters" or, in the United States brakemen, travelling for the purpose on those vehicles operated the brakes. Some railways fitted a special deep-noted brake whistle to locomotives to indicate to the porters the necessity to apply the brakes. All the brakes at this stage of development were applied by operation of a screw and linkage to brake bloc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Coupling
A coupling or coupler is a mechanism, typically located at each end of a rolling stock, rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train. Throughout the history of rail vehicles, a variety of coupler designs and types have been developed worldwide. Key design considerations include strength, reliability, easy and efficient handling, and operator safety. Automatic couplers engage automatically when the cars are pushed together. Modern versions not only provide a mechanical connection, but can also couple brake lines and data lines. Different countries use different types of couplers. While North American railroads and China use Janney couplers, railroads in the former Soviet Union use SA3 couplers and the European countries use Scharfenberg coupler, Scharfenberg and Buffers and chain coupler, screw ...

LNWR 17in Coal Engine
The LNWR 17in Coal Engine was a class of 0-6-0 steam tender engines designed by Francis Webb for the London and North Western Railway. They were simple locomotives and in UK service they were very reliable. "17in" refers to their cylinder diameter in inches. They were called "Coal Engines" because they were used for hauling coal trains. Design and construction The ''17in Coal Engine'' was the first new design of engine to be built by Webb since he became Chief Engineer of the LNWR in September 1871. A policy of 'low costs' was in force at the LNWR, with running costs per engine mile reduced from d per engine mile in 1857 to d by 1871. The first 17in Coal Engine was constructed in 1873, the first of almost five hundred built. Ernest L. Ahrons is quoted as regarding the type as "probably the simplest and cheapest locomotives ever made in this country", and O. S. Nock described them as "splendid". Many aspects of the 17in Coal's design reflected John Ramsbottom's final desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

EMD SD40
The EMD SD40 is a model of 6-axle diesel-electric locomotive built by Electro-Motive Diesel, General Motors Electro-Motive Division between January 1966 and August 1972. 1,268 locomotives were built between 1966 and 1972. In 1972, an improved version with new electronics was developed and marketed as a new locomotive, the EMD SD40-2, SD40-2. Design Like its predecessor in EMD's catalog, the EMD SD35, SD35, the SD40 is a high-horsepower, six-axle freight locomotive. The SD40 is a member of EMD's long-running Special Duty class of locomotives, which all are built with 6 axles. In 1966, Electro-Motive Diesel, EMD updated its locomotive catalog with entirely new models, all powered by the new EMD 645, 645 diesel engine. These included six-axle models EMD SD38, SD38, SD40, EMD SDP40, SDP40 and EMD SD45, SD45.

GE AC4400CW
The GE AC4400CW, sometimes referred as "AC44CW", is a diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. It is similar to the Dash 9-44CW, but uses AC traction motors instead of DC, with a separate inverter per motor. 3,018 units were built for North American railroads over an 11-year production and 540 AC44i units for the Brazilian railroads. In 2005, all Class I freight railroads except Norfolk Southern and Canadian National owned at least one AC4400CW. Norfolk Southern ordered the very similar C40-9Ws, although NS would later acquire 36 former CEFX AC4400CWs in August 2023. As a result of more stringent emissions requirements that came into effect in January 2005, GE no longer offers the AC4400CW, replacing it with the ES44AC. Design variations The AC4400CW was the first GE locomotive to offer an optional self-steering truck design, intended to increase adhesion and reduce wear on the railhead. This option was specifie ...
