A1A-3 Locomotives
The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead. The AAR system counts axles instead of wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to two powered axles in a row, "C" to three powered axles in a row, and "D" to four powered axles in a row. "1" refers to one idler axle, and "2" to two idler axles in a row. A dash ("–") separates trucks or wheel assemblies. A plus sign ("+") refers to articulation, either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of couplers. 1A-A1 "1A- ...

Wheel Arrangement
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered. Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. Major notation schemes The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC classificat ...

FM OP800
The OP800 was a lightweight, streamlined railcar built by the St. Louis Car Company in 1939. Fairbanks-Morse supplied the , five-cylinder opposed piston engine prime mover. The units were configured in a highly unusual 2-A1A wheel arrangement ''(later converted to 3-A1A)'' mounted atop a pair of road trucks, and equipped with a front swing coupler pilot. The aft section was divided into two separate compartments: one was used to transport baggage and the other served as a small railway post office, or RPO (the forward door, located just behind the radiator louvers, was equipped with a mail hook). Six units, accompanied by matching trailing car sets, were manufactured exclusively for the Southern Railway. Two were later sold to the Georgia and Florida Railroad and Georgia Northern Railway as maintenance cars. The remaining four OP800s were scrapped in 1955; selected parts were retained for maintenance use on other SR F-M motive power. At least four of these cars had individu ...

GEVO
The Evolution Series is a line of diesel locomotives built by GE Transportation Systems (now owned by Wabtec), initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine. The Evolution Series was named as one of the "10 Locomotives That Changed Railroading" by ''Trains Magazine'' and was the only locomotive introduced after 1972 to be included in that list. The Evolution Series locomotives are some of the best-selling and most successful freight locomotives in United States history. Models Currently, six different Evolution Series models have been produced for the North American market. They are all six axle locomotives and have the wheel arrangement C-C ( AAR classification) or Co′Co′ (UIC classification), except for ...

BNSF
BNSF Railway is one of the largest freight railroads in North America. One of seven North American Class I railroads, BNSF has 35,000 employees, of track in 28 states, and nearly 8,000 locomotives. It has three transcontinental routes that provide rail connections between the western and eastern United States. BNSF trains traveled over in 2010, more than any other North American railroad. The BNSF Railway Company is the principal operating subsidiary of parent company Burlington Northern Santa Fe, LLC. Headquartered in Fort Worth, Texas, the railroad's parent company is a wholly owned subsidiary of Berkshire Hathaway, Inc., of Omaha, Nebraska. The current CEO is Kathryn Farmer. According to corporate press releases, the BNSF Railway is among the top transporters of intermodal freight in North America. It also hauls bulk cargo, including enough coal to generate around 25% of the electricity produced in the United States. The creation of BNSF started with the formation o ...

FM Erie-built
The Erie-built was the first streamlined, cab-equipped dual service diesel locomotive built by Fairbanks-Morse, introduced as direct competition to such models as the ALCO PA and FA and EMD FT. F-M lacked the space and staff to design and manufacture large road locomotives in their own plant at Beloit, Wisconsin, and was concerned that waiting to develop the necessary infrastructure would cause them to miss out on the market opportunity for large road locomotives. Engineering and assembly work was subcontracted out to General Electric, which produced the locomotives at its Erie, Pennsylvania, facility, thereby giving rise to the name "Erie-built." At the time, diesel road power was sold as multi-unit locomotives. The Erie-Built used the , ten-cylinder version of F-M's Model 38D 8-1/8 opposed piston diesel engine, which had seen success as a submarine powerplant in World War II, as its prime mover. This allowed the Erie-Built to deliver a locomotive consisting of only three unit ...

ALCO PA
The ALCO PA was a family of A1A-A1A diesel locomotives built to haul passenger trains. The locomotives were built in Schenectady, New York, in the United States, by a partnership of the American Locomotive Company (ALCO) and General Electric (GE) between June, 1946 and December, 1953. Designed by General Electric's Ray Patten (along with their ALCO FA cousins), they were of a cab unit design; both cab-equipped lead A unit PA and cabless booster B unit PB models were built. While externally the PB models were slightly shorter than the PA model, they shared many of the same characteristics, both aesthetically and mechanically. However, they were not as reliable as EMD E-units. ALCO's designation of P indicates that they were geared for higher speeds and passenger use, whereas the F designation marks these locomotives as being geared primarily for freight use. However, beyond this, their design was largely similar - aside from the PA/PB's both being larger A1A-A1A types with an e ...

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 ...

Chicago And North Western Railway
The Chicago and North Western was a Class I railroad in the Midwestern United States. It was also known as the "North Western". The railroad operated more than of track at the turn of the 20th century, and over of track in seven states before retrenchment in the late 1970s. Until 1972, when the employees purchased the company, it was named the Chicago and North Western Railway (or Chicago and North Western Railway Company). The C&NW became one of the longest railroads in the United States as a result of mergers with other railroads, such as the Chicago Great Western Railway, Minneapolis and St. Louis Railway and others. By 1995, track sales and abandonment had reduced the total mileage to about 5,000. The majority of the abandoned and sold lines were lightly trafficked branches in Iowa, Illinois, Minnesota, South Dakota and Wisconsin. Large line sales, such as those that resulted in the Dakota, Minnesota and Eastern Railroad, further helped reduce the railroad to a mainline ...

Baldwin DR-6-2-10
Baldwin Locomotive Works produced several different Baldwin DR-6 models of 6-axle passenger train-hauling diesel locomotives between 1945 and 1948. The series comprised eight individual versions, all of which sold only in small numbers; across all versions, only 39 locomotives were produced. Each version was produced only for a single railroad. Many shared the same Baldwin model number, DR-6-4-2000, even though they were rather different; this was because the Baldwin model only encoded the total axles (6), the driven axles (4) and the power output (). The single exception was the single unit produced for the Chicago and North Western Railway, which had a single engine and was model number DR-6-2-1000. In the AAR wheel arrangement scheme of classification, these locomotives were of A1A-A1A and A1A-3 arrangements, respectively. Baldwin demonstrators The first produced version comprised a pair of DR-6-4-2000 demonstrators built in 1945. This, unlike later models, used Baldwin's ...

General Pershing Zephyr
The ''General Pershing Zephyr'' was the ninth of the Chicago, Burlington & Quincy Railroad's ''Zephyr'' streamliners, and the last built as an integrated streamliner rather than a train hauled by an EMD E-unit diesel locomotive. It was constructed in 1939 with bodywork and passenger cars by Budd Company and diesel engine, electric transmission, power truck, and other locomotive equipment by General Motors Electro-Motive Corporation. Because its intended Kansas City to St Louis route passed near the birthplace and boyhood home of famous World War I General John J. Pershing, the train was named after him. The power car was named ''Silver Charger'', after Pershing's horse ''Charger'', while the passenger cars were named after United States Army badges of rank—''Silver Leaf'', ''Silver Eagle'', and ''Silver Star''. The train replaced the '' Ozark State Zephyr'', which had been inaugurated three years earlier. In September, 1938, a second set was added, the 9903, which had ...

Rebel (train)
The Gulf, Mobile and Northern Railroad ''Rebels'' were lightweight, streamlined diesel-electric trains built by American Car and Foundry. The first two trains, purchased in 1935, provided service over the roughly between New Orleans, Louisiana, and Jackson, Tennessee. The third train, purchased in 1937, allowed service to be added between Jackson and Mobile, Alabama. Unlike other earlier diesel streamliners, these trains were not articulated, as their normal operation required adding and removing cars from the consist. The trains were powered by lightweight, shovel-nosed power cars, styled by Otto Kuhler, and equipped with , six-cylinder McIntosh & Seymour 531 prime movers and Westinghouse electric transmission components. The units had an uncommon 2-B wheel arrangement, mounted atop a pair of road trucks. The aft section was divided into two separate compartments: one was used to transport baggage and the other served as a small railway post office, or RPO (the forward ...

American Car And Foundry
ACF Industries, originally the American Car and Foundry Company (abbreviated as ACF), is an American manufacturer of railroad rolling stock. One of its subsidiaries was once (1925–54) a manufacturer of motor coaches and trolley coaches under the brand names of (first) ACF and (later) ACF-Brill. Today, the company is known as ACF Industries LLC and is based in St. Charles, Missouri. It is owned by investor Carl Icahn. History The American Car and Foundry Company was originally formed and incorporated in New Jersey in 1899 as a result of the merger of thirteen smaller railroad car manufacturers. The company was made up of: Later in 1899, ACF acquired the Bloomsburg Car Manufacturing Company of Bloomsburg, Pennsylvania. Orders for new freight cars were made very quickly, with several hundred cars ordered in the first year alone. Two years later, ACF acquired the Jackson and Sharp Company (founded 1863 in Wilmington, Delaware) and the Common Sense Bolster Company (of Chic ...
