Southern Pacific 9010
Southern Pacific 9010 is a KM ML 4000 C′C′ diesel-hydraulic locomotive, built in 1964 by German manufacturer Krauss-Maffei for the Southern Pacific Railroad. SP 9010 generated from two V16 Maybach MD870 diesel engines. It is the sole surviving ML 4000 C′C′ built for use in North America, and the sole surviving mainline diesel-hydraulic locomotive in North America. (Several diesel-hydraulic switchers exist in service and in museums). It was painted to Southern Pacific's 1958 standard, the so-called 'bloody nose' colors of Scarlet and Lark Dark Gray, for its entire operating career. It was renumbered to SP 9113 in late 1965, rebuilt extensively at SP's Sacramento General Shops (later Sacramento Locomotive Works) during the latter half of 1966, and was initially retired in 1968. It was revived and rebuilt by Sacramento General Shops into a 'camera car' for the purpose of shooting motion picture background plates for a ground-based full-motion locomotive training simulat ...

C′C′
Co-Co is the wheel arrangement for diesel and electric locomotives with two six-wheeled bogies with all axles powered, with a separate traction motor per axle. The equivalent UIC classification (Europe) for this arrangement is Co′Co′, or C-C for AAR (North America). Use Co-Cos are most suited to freight work as the extra wheels give them good traction. They are also popular because the greater number of axles results in a lower axle load to the track. History The first mainline diesel-electric locomotives were of Bo-Bo arrangement. As they grew in power and weight, from 1937 the EMD E-units used an A1A-A1A layout with six axles to reduce axle load. After WWII, the British LMS ordered two prototype locomotives with some of the first Co-Co arrangements. The first C-C design recorded was a narrow-gauge Hornsby opposed-piston Hornsby-Akroyd-engined locomotive of 1903 for the Chattenden and Upnor Railway. There was a two-speed mechanical transmission with drive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

EMD SD45
The SD45 is a six-axle diesel-electric locomotive class built by General Motors Electro-Motive Division between 1965 and 1971. It has an EMD 645E3 twenty- cylinder engine generating on the same frame as the SD38, SD39, SD40, and SDP40. As of 2023, most SD45s have been retired, scrapped or rebuilt to SD40-2 standards. Design A total of 1,260 were built for American railroads before the SD45-2 replaced it in 1972, along with the related SD45T-2 'Tunnel Motor'. SD45s had several teething problems. Reliability was not as high as anticipated; the twenty-cylinder prime mover was prone to crankshaft failure from engine block flex. Though it produced more than the 16-645E3 in the SD40, some railroads felt the extra horsepower was not worth it, even after EMD strengthened the block to eliminate crankshaft failures. At low speeds when tractive effort was adhesion-limited, the SD45 provided no advantage over the SD40. Buyers included the Burlington Northern, Southern Pacific ...

EMD GP9
The EMD GP9 is a four-axle diesel-electric locomotive built by Electro-Motive Diesel, General Motors' Electro-Motive Division between 1954 and 1963. The GP9 succeeded the EMD GP7, GP7 as the second model of EMD's General Purpose (GP) line, incorporating a new sixteen-cylinder (engine), cylinder engine which generated . This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives. The GP9 was succeeded by the similar but slightly more powerful EMD GP18, GP18. Design and production EMD designed the GP9 as an improved version of the GP7, with an increase in power from 1,500 hp to 1,750 hp, and a change in prime mover to the latest version of the EMD 567, 567 engine, the 567C. Externally, the GP9 strongly resembled its predecessor. Most were built with high short hoods, but the Southern Pacific Transportation Company, Southern Pacific ordered a number with low short hoods for improved crew visibility. EMD b ...

EMD F7
The EMD F7 is a model of diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD). Although originally promoted by EMD as a freight-hauling unit, the F7 was also capable of passenger service, and used in hauling trains such as the Santa Fe Railway's high-speed flagship trains, the '' Super Chief, & El Capitan'', and the Ontario Northland's '' Northlander''. History The F7 was the fourth model in GM-EMD's successful line of F-unit locomotives, and by far the best-selling cab unit of all time. In fact, more F7s were built than all other F-units combined. The F7 succeeded the F3 model in GM-EMD's F-unit series, and was replaced in turn by the F9. Final assembly was at GM-EMD's La Grange, Illinois, plant or GMD's London, Ontario, facility. There was no F4, -5 or -6 model; "7" was chosen to match the contemporary twin-engine E7, and was also applied to the new GP ...

Donner Pass
Donner Pass is a mountain pass in the northern Sierra Nevada, above Donner Lake and Donner Memorial State Park about west of Truckee, California. Like the Sierra Nevada themselves, the pass has a steep approach from the east and a gradual approach from the west. The pass has been used by the California Trail, First transcontinental railroad, Overland Route, Lincoln Highway and Victory Highway (both later U.S. Route 40 and still later Donner Pass Road), as well as indirectly by Interstate 80. The pass gets its name from the ill-fated Donner Party who overwintered there in 1846. Today the area is home to a thriving recreational community with several alpine lakes and ski resorts ( Donner Ski Ranch, Boreal, and Sugar Bowl). The permanent communities in the area include Kingvale and Soda Springs, as well as the larger community below the pass surrounding Donner Lake.

Consist
A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive ...

EMD F-unit
EMD F-units are a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois, and the GMDD plant in London, Ontario. They were sold to railroads throughout the United States, Canada and Mexico, and a few were exported to Saudi Arabia. The term ''F-unit'' refers to the model numbers given to each successive type (i.e. F3, F7, etc.), all of which began with the letter ''F''. The ''F'' originally meant "fourteen", as in , not "freight". Longer EMD E-units for passenger service had twin diesel engines (called " prime movers" in that type of application). The ''E'' meant "eighteen" as in . Similarly, for early model EMD switchers, ''S'' meant "six hundred" and ''N'' meant "nine hundred horsepower" ( respectively). F-units were originally designed for freight service, although many without steam generat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
