EMD E-units
EMD E-units were a line of passenger train streamliner diesel locomotives built by the General Motors Electro-Motive Division (EMD) and its predecessor the Electro-Motive Corporation (EMC). Final assembly for all E-units was in La Grange, Illinois. Production ran from May 1937, to December, 1963. The name ''E-units'' refers to the model numbers given to each successive type, which all began with E. The E originally stood for eighteen hundred horsepower (1800 hp = 1300 kW), the power of the earliest model, but the letter was kept for later models of higher power. The predecessors of the E-units were the EMC 1800 hp B-B locomotives built in 1935. These had similar power and mechanical layouts to the E-units, but in boxcab bodies on AAR type B two-axle trucks. EMC also introduced the TA model in 1937, selling six to the Rock Island. This had similar carbody styling, but otherwise had more in common with UP M-10001, M-10002, and M-10003 to M-10006, in that it was a ...

Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, 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-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 part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power station. Weight distribution The power unit rep ...

EMD E6
The EMD E6 was a , A1A-A1A, streamlined passenger train locomotive manufactured by Electro-Motive Corporation, and its corporate successor, General Motors Electro-Motive Division, of La Grange, Illinois. The cab version, E6A, was manufactured from November 1939 to September 1942; 91 were produced. The booster version, E6B, was manufactured from April 1940 to February 1942; 26 were produced. The was achieved by putting two , 12-cylinder, model 567 engines in the engine compartment. Each engine drove its own electrical generator to power the traction motors. The E6 was the seventh model in a long line of passenger diesels of similar design known as EMD E-units. Compared with passenger locomotives made later by EMD, the noses of the E3, E4, E5, and E6 cab units had pronounced slants when viewed from the side. Therefore, these four models have been nicknamed "slant nose" units. Later E models had the "bulldog nose" of the F series. One interesting E6 variant custom-produced for ...

EMD E5
The EMD E5 is a , A1A-A1A passenger train-hauling diesel locomotive manufactured by Electro-Motive Corporation, and its corporate successor, General Motors' Electro-Motive Division (EMD) of La Grange, Illinois, and produced exclusively for the Chicago, Burlington and Quincy Railroad (“The Burlington Route”), and its subsidiaries, during 1940 and 1941. The E5 was distinguished from the otherwise very similar E3, E4 and E6 by being clad in polished stainless steel to match the Burlington's ''Zephyr'' trains. It also featured unique small grill-like ornamentation on both sides of the upper headlight. Like the other models in the E-series, the E5 had a sloping “slant nose” and it was equipped with two headlights — a regular stationary headlight above a gyrating Mars signal light. The E5 was the sixth in the EMD E-unit series. Engine and powertrain The E5 used twin 12 cylinder 567 engines developing a total of at 800 rpm. Designed specifically for railroad locomotives, t ...

EMC E4
The EMC E4 was a , A1A-A1A passenger train-hauling diesel locomotive built by the Electro-Motive Corporation of La Grange, Illinois. All were built for the Seaboard Air Line Railway. The E4 was the fifth model in a long line of passenger diesels of similar design known as EMD E-units. The was achieved with two EMC model 567 V12 engines developing , each engine driving its own electrical generator to power the traction motors. The front noses of the EA, E1A, E3A, E4A, E5A, and E6A cab units had a pronounced slant when viewed from the side. Therefore, these six models have been nicknamed "slant nose" units. Later E-unit models received the same blunted "bulldog nose" as the F-units. Ironically, the E4 was produced before the E3. Both models were identical, save for the E4 having a pneumatically-operated nose door passageway in order to facilitate crew movement between units in a locomotive consist. All the E4s were retired and scrapped by 1964. Original owners See a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMC E3
The EMC E3 is a , A1A-A1A passenger train locomotive that was manufactured by Electro-Motive Corporation of La Grange, Illinois. The EMC demonstrator #822 was released from La Grange for test on September 12, 1938. The cab version, or E3A, was manufactured from September 1938 to June 1940, and 17 were produced. The booster version, or E3B, was manufactured in March 1939 and September 1939, and 2 were produced. The was achieved by putting two , 12-cylinder, model 567 engines in the engine compartment. Each engine drove its own electrical generator to power the traction motors. The E3 was the fourth model in a long line of passenger diesels of similar design known as EMD E-units. Compared with passenger locomotives made later by EMD, the noses of the E3, E4, E5, and E6 cab units had pronounced slants when viewed from the side. Therefore, these four models have been nicknamed "slant nose" units. Later E models had the more vertical "bulldog nose" of the F series. E3 demonstra ...

EMC E2
The EMC E2 was an American passenger-train diesel locomotive which as a single unit developed , from two (2) prime movers. These locomotives were typically operated as a unit set ( A - B - B) or ( A - B - A); where the three unit lashup developed 5400 horsepower. This was almost the ideal horsepower required () for the tonnage of a 15 - 18 car passenger train, operated over the ruling grades of virtually all of the mileage between major American cities. The units were of the A1A-A1A wheel arrangement, and manufactured by Electro-Motive Corporation (EMC), later Electro-Motive Diesel (EMD) of La Grange, Illinois. Two sets (each of three units, A-B-B) () were produced in 1937 for named passenger trains; the first set (SF-1, SF-2, and SF-3) for the '' City of San Francisco''. These motive-power sets were jointly owned and operated by the Union Pacific Railroad, the Chicago and North Western Railway, and the Southern Pacific Railroad. The second A-B-B set (LA-1, LA-2, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMC E1
The EMC E1 was an early passenger-train diesel locomotive developing 1,800 hp, with an A1A-A1A wheel arrangement, and manufactured by Electro-Motive Corporation of La Grange, Illinois. They were built during 1937 and 1938 for the Atchison, Topeka and Santa Fe Railway for a new generation of diesel-powered streamlined trains. 8 cab-equipped lead A units and three cabless booster B units were built. The initial three locomotives were AB pairs built to haul the Santa Fe's ''Super Chief'' diesel streamliners, while the others were built as single A units to haul shorter trains. The locomotives were diesel-electrics with two Winton 201-A engines each, with each engine driving its own generator to power the traction motors. The E1 was the second model in a long line of passenger diesels of similar design known as EMD E-units. All Winton 201A-engined Santa Fe passenger units, including the E1s, were extensively rebuilt into the 80-class E8M engines in 1952-53. These were simila ...

EMC EA/EB
The EMC EA/EB is an early passenger train-hauling diesel locomotive built from May 16, 1937, to 1938 by Electro-Motive Corporation of La Grange, Illinois for the Baltimore and Ohio Railroad. They were the first model in a long line of passenger diesels of similar design known as EMD E-units. Each locomotive unit developed from two Winton 201-A diesel engines, driving the wheels through an electric transmission—the generator driven by each engine provided current for traction motors. The locomotives were of A1A-A1A wheel arrangement—two three-axle trucks of which only the outer two axles were powered. Six two-unit locomotives were produced, each consisting of a lead cab-equipped EA A unit and a cabless booster EB B unit. They were numbered 51 through 56; the A units bore the bare number and the B units the number followed by 'X'.

Economies Of Scale
In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of time. A decrease in cost per unit of output enables an increase in scale. At the basis of economies of scale, there may be technical, statistical, organizational or related factors to the degree of market control. This is just a partial description of the concept. Economies of scale apply to a variety of the organizational and business situations and at various levels, such as a production, plant or an entire enterprise. When average costs start falling as output increases, then economies of scale occur. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis. The economic concept dates back to Adam Smith and the idea of obtaining larger production returns through the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
