FM H-24-66
The H-24-66, or Train Master, is a diesel-electric railroad locomotive produced by Fairbanks-Morse and its licensee, Canadian Locomotive Company. These six-axle hood unit road switchers were used in the United States and Canada during the 1950s. They were the successor to the unsuccessful Consolidated line of cab units produced by F-M and CLC in the 1950s. Each locomotive produced 2,400 horsepower (1.8 MW). Like other F-M locomotives, the Train Master used an opposed-piston prime mover. It rode on a pair of drop-equalized three-axle "Trimount" trucks, giving it a C-C wheel arrangement. Overview Advertised by Fairbanks-Morse as "the most useful locomotive ever built", the 2,400-horsepower (1.8 MW) H-24-66 Train Master was the most powerful single-engine diesel locomotive at its introduction in 1953. No competitor offered a locomotive with an equal horsepower rating until the ALCO RSD-7 entered production in January 1954. EMD followed suit in July 1958 with the SD24, and GE ...

Road Switcher
A road switcher locomotive is a type of railroad locomotive designed to both haul railroad car, railcars in mainline service and Shunting (rail), shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere. A road switcher must be able to operate and have good visibility in both directions. As a road engine, a road switcher must be able to operate at road speeds, with suitable power and cooling capacity. It has high-speed road trucks rather than low-speed switcher only trucks. Modern road trucks are always equipped with "frictionless" roller bearings, whereas switcher trucks were almost always equipped with "friction" plain bearings, until plain bearings were outlawed in interchange service on both railcars and locomotives. Overview For the reasons given above, road switchers are generally hood units. The set-back cab of a hood unit provides more safety in the event of a collision at speed than most switche ...

Canadian National Railway
The Canadian National Railway Company () is a Canadian Class I freight railway headquartered in Montreal, Quebec, which serves Canada and the Midwestern and Southern United States. CN is Canada's largest railway, in terms of both revenue and the physical size of its rail network, spanning Canada from the Atlantic coast in Nova Scotia to the Pacific coast in British Columbia across approximately of track. In the late 20th century, CN gained extensive capacity in the United States by taking over such railroads as the Illinois Central. CN is a public company with 24,671 employees and, , a market cap of approximately US$75 billion. CN was government-owned, as a Canadian Crown corporation, from its founding in 1919 until being privatized in 1995. , Bill Gates was the largest single shareholder of CN stock, owning a 14.2% interest through Cascade Investment and his own Gates Foundation. From 1919 to 1978, the railway was known as "Canadian National Railways" (CNR). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Pacific Transportation Company
The Southern Pacific (or Espee from the railroad initials) was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company. The original Southern Pacific began in 1865 as a land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad. The Southern Pacific legacy founded hospitals in San Francisco, Tucson, and Houston. In the 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This telecommunications network became part of Sprint, a company ...

Wabash Railroad
The Wabash Railroad was a Class I railroad that operated in the mid-central United States. It served a large area, including track in the states of Ohio, Indiana, Illinois, Iowa, Michigan, and Missouri and the province of Ontario. Its primary connections included Chicago, Illinois; Kansas City, Missouri; Detroit, Michigan; Buffalo, New York; St. Louis, Missouri; and Toledo, Ohio. The Wabash's major freight traffic advantage was the direct line from Kansas City to Detroit, without going through St. Louis or Chicago. Despite being merged into the Norfolk and Western Railway (N&W) in 1964, the Wabash company continued to exist on paper until the N&W merged into the Norfolk Southern Railway (NS) in 1982. At the end of 1960 Wabash operated 2,423 miles of road on 4,311 miles of track, not including Ann Arbor Railroad (1895–1976), the Ann Arbor Railroad and the New Jersey, Indiana and Illinois Railroad; that year it reported 6,407 million net ton-miles of revenue freight and 164& ...

GE U25C
The U25C is a diesel locomotive built by General Electric intended for the United States domestic market. Launched in September 1963, it remained in production until December 1965. It was replaced by the U28C. Development The origin of the U25C grew out of the need for six axle locomotives to operate on a 12-mile heavy haul railroad to construct Oroville Dam. The General Electric salesman to Oro Dam Constructors offered essentially a U25B riding on six axle trucks. When the salesman got back to GE's Erie Plant it was discovered that no six axle U25 was available, nor did GE wish to construct a domestic six axle road switcher until the horsepower threshold reached 3000 horsepower. Rather than lose the four unit sale GE quickly began a design of a six axle U25 that relied heavily on the U25B for engineering. The U25C was longer than the U25B by four feet four inches. The extra length was needed to accommodate the improved Trimount trucks. Completed in September 1963 the U25C was th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD24
The EMD SD24 is a six-axle ( C-C) diesel-electric locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois between July 1958 and March 1963. A total of 224 units were built for customers in the United States, comprising 179 regular, cab-equipped locomotives and 45 cabless B units. The latter were built solely for the Union Pacific Railroad. The SD24 was the first EMD production locomotive to be built with an EMD turbocharged diesel engine. The first SD24 was built sixteen months before the four-axle ( B-B) model GP20. Power output of the SD24 was 33 percent higher than the of the concurrent Roots blower-equipped SD18s with the same engine displacement. The SD24 has per axle, limited by the traction motors available. Nevertheless, the turbocharged SD24 provides full rated power at all altitudes, which the Roots-blown SD18 could not provide. In terms of sales, the SD24 was only a moderate success, and had average service lives in SD24 configuration (th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electro-Motive Diesel
Electro-Motive Diesel (abbreviated EMD) is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD has been owned by Progress Rail since 2010. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail, a subsidiary of the heavy equipment manufacturer Caterpillar Inc., Caterpillar. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel. EMD's headquarters and engineering facilities are based in McCook, Illinois, while its final locomotive assembly line is located in Muncie, Indiana.

ALCO RSD-7
The ALCO RSD-7 was a diesel-electric locomotive of the road switcher type built by ALCO at Schenectady, New York between January 1954 and April 1956. Two versions were built, with the same RSD-7 model designation but different specifications and power ratings, although both used the ALCO 244 engine in V16 configuration. Specification DL-600, of which only two were built, developed and used the 244G engine. The revised specification DL-600A, numbering 27 locomotives, was rated at and used the 244H engine. The RSD-7 was superseded by the ALCO 251-engined ALCO RSD-15, which looks very similar. The RSD-7 was the last ALCO diesel built with a 244 engine. Both rode on a pair of three-axle trucks with all three axles on each truck powered; this is a C-C wheel arrangement. These trucks have an unequal axle spacing due to traction motor positioning; the outer two axles on each truck are closer together than the inner two. The RSD-7 used the GE 752 traction motor. The six-motor design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie
A bogie ( ) (or truck in North American English) comprises two or more Wheelset (rail transport), wheelsets (two Railroad wheel, wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly (trailer), dolly in a road train or in railway bogie exchange). It may include Suspension (vehicle), suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of continuous track, tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. Rail ...

Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts chemical energy of a fuel into useful work. In a locomotive, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-hydraulic locomotive, the prime mover is the diesel engine that powers the pumps of one or more torque converters mechanically coupled to the drivers. In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not p ...

Opposed Piston Engine
An opposed-piston engine is a piston engine in which each cylinder has a piston at both ends, and no cylinder head. Petrol and diesel opposed-piston engines have been used mostly in large applications such as ships, military tanks, and factories. Current manufacturers of opposed-piston engines include Cummins, Achates Power, and Fairbanks-Morse Defense (FMDefense). Design Compared to contemporary two-stroke engines, which use a conventional design of one piston per cylinder, the advantages of the opposed-piston engine are: * Eliminating the cylinder head and valve-train, which reduces weight, complexity, cost, heat loss, and friction loss of the engine. * Creating a uniflow-scavenged movement of gas through the combustion chamber, which avoided the drawbacks originally associated with the crossflow-scavenged designs of early piston-engines. * A reduced height of the engine The main drawback was that the two opposing pistons had to be geared together. This added weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
