Cab Unit
In North American railroad terminology, a cab unit is a railroad "locomotive" with its own cab and controls. "Carbody unit" is a related term, which may be either a cabless booster unit controlled from a linked cab unit, or a cab unit that contains its own controls. Characteristics With both body styles, a bridge-truss design framework is used to make the body a structural element of the locomotive. The body extends the full width and length of the locomotive. The service walkways are inside the body. Carbody units, gaining rigidity from the body trusswork, require less structural weight to achieve rigidity than do locomotives with non-structural bodies. For that reason, carbody construction was favored to increase the power-to-weight ratio for early diesel locomotives, before the power available with diesel technology was increased. Recent years have seen carbody construction revived in the quest for greater fuel efficiency with passenger locomotives. The full-width body ...

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 ...

ALCO DL-203
The ALCO DL-202-2 and DL-203-2 diesel-electric locomotive (known informally as the Black Maria) was an experimental freight locomotive produced by ALCO of Schenectady, New York. The primary diesel builders Alco, Baldwin and EMD pushed the War Production Board (WPB) for more opportunities to build more diesels. The Transportation Equipment Division of the WPB announced a production schedule on December 10, 1943, that allowed Alco to build one 4500 horsepower experimental diesel locomotive. This experimental diesel locomotive was to be built in the fourth quarter of 1944. The two A units were built in January 1945 and the B unit at a later date in 1945. The two A units were put on test at Building No. 37 at Schenectady to work out problems with the connecting rods and turbocharger in the Alco 241 engine, developed by both McIntosh and Seymour and ALCo. The total production run included 2 cab DL202-2 A units, and a single DL203-2 B (cabless booster) unit. The locomotives were powere ...

ALCO DL-109
The ALCO DL-109 was one of six models of A1A-A1A Diesel locomotives built to haul passenger trains by the American Locomotive Company (ALCO) between December, 1939 and April, 1945 ("DL" stands for Diesel Locomotive). They were of a cab unit design, and both cab-equipped lead A units DL-103b, DL-105, DL-107, DL-109 and cabless booster B units DL-108, DL-110 models were built. The units were styled by noted industrial designer Otto Kuhler, who incorporated into his characteristic cab (US Patent D121,219) the trademark three-piece windshield design. A total of 74 cab units and four cabless booster units were built. History All models developed . The first unit built as ALCO Specification DL-103b was longer than the other cab units, and became Chicago, Rock Island and Pacific Railroad #624. The DL-103b had the two radiator sections positioned together at the end of the carbody, while all other units had a split radiator arrangement with one placed at the back of the unit and one ...

EMC AB6
The EMC AB6 was a type of diesel locomotive built exclusively for the Chicago, Rock Island and Pacific Railroad (the "Rock Island Line") by General Motors' Electro-Motive Corporation and delivered in June 1940. Two examples were built, numbered #750 and #751. They were built for the ''Rocky Mountain Rocket'' passenger train, which travelled as a unified train from Chicago, Illinois, to Limon, Colorado, which then divided. One section went to Colorado Springs, Colorado, and the other to Denver, Colorado. The Rock Island desired a locomotive that could look like an integrated part of the train during the Chicago-Limon portion of the route, and could then be operated independently to take three cars to Colorado Springs. A regular, cab-equipped A-unit could have been purchased, but that would have ruined the streamlined look of the train, so the RI had EMC build a flat-fronted locomotive based on an E-series E6B (B unit) but with an operating cab, headlight, pilot, and other fe ...

EMC AA
AA was a designator used for several different diesel locomotive types custom built by General Motors Corporation EMC/GM with passenger or baggage space in the same body. This locomotive is listed as class AA-6 by R. Craig, and the designation is logical as the locomotive is described as "half an E6" in the Second Diesel Spotter's Guide. One such was a single locomotive built for the Missouri Pacific Railroad, delivered in August 1940, numbered #7100. MP 7100 was built for service with the ''Delta Eagle'' passenger train, which ran between Memphis, Tennessee and Tallulah, Louisiana. Note: Missouri Pacific ordered all their 'E' units with portholes instead of square windows like most of the E series from the EA to E7's. This was the only MoPac unit with square windows (on the baggage door). Since the two-car train the unit would have to haul was comparatively light, the AA was built with only one 1,000 hp EMD 567 V12 prime mover, and a baggage compartment where the second d ...

EMD FL9
The EMD FL9 (New Haven Class EDER-5) is a model of electro-diesel locomotive, capable of operating either as a traditional diesel-electric locomotive or as an electric locomotive powered from a third rail. Sixty units were built between October 1956 and November 1960 by General Motors Electro-Motive Division for the New York, New Haven and Hartford Railroad (the "New Haven"). Design Due to concerns about diesel emissions in the East River Tunnels and the underground tracks of Grand Central Terminal and Penn Station, passenger trains entering New York City have long been required to use electrical power, as diesel exhaust would pose a hazard to human health in the confined underground spaces. At the same time, much of the New Haven's trackage was not electrified beyond New Haven. To allow passenger trains to travel to New York City from non-electrified lines without requiring a change of locomotives, the New Haven Railroad purchased a class of locomotive that could switch between d ...

EMD FP9
The EMD FP9 is an American , B-B dual-service passenger and freight-hauling diesel locomotive that was produced between February 1954 and December 1959 by General Motors Electro-Motive Division, and General Motors Diesel. Final assembly was at GM-EMD's La Grange, Illinois plant, except for Canadian orders, which were assembled by Canadian subsidiary GMD at London, Ontario. The FP9 was essentially EMD's F9 locomotive extended by four feet to give greater steam generator and water capacity for hauling passenger trains. A total of 90 cab-equipped lead A units were built; unlike the freight series, no cabless booster B units were sold. Regular F9B units were sometimes used with FP9 A units, since they, lacking cabs, had more room for water and steam generators. The FP9 and its predecessor, the FP7, were offshoots of GM-EMD's highly successful F-unit series of cab unit diesel locomotives.

EMD FP7
The EMD FP7 is a , B-B dual-service passenger and freight-hauling diesel locomotive produced between June 1949 and December 1953 by General Motors' Electro-Motive Division and General Motors Diesel. Final assembly was at GM-EMD's La Grange, Illinois plant, excepting locomotives destined for Canada, in which case final assembly was at GMD's plant in London, Ontario. The FP7 was essentially EMD's F7A locomotive extended by four feet to give greater water capacity for the steam generator for heating passenger trains. Design While EMD's E-units were successful passenger engines, their A1A-A1A wheel arrangement made them less useful in mountainous terrain. Several railroads had tried EMD's F3 in passenger service, but there was insufficient water capacity in an A-unit fitted with dynamic brakes. The Atchison, Topeka and Santa Fe Railway's solution was to replace the steam generators in A-units with a water tank, and so only fitted steam generators into the B-units. The Norther ...

EMD E9
The E9 is a , A1A-A1A passenger train-hauling diesel locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois, between April 1954 and January 1964. 100 cab-equipped A units were produced and 44 cabless booster B units, all for service in the United States. The E9 was the tenth and last model of EMD E-unit and differed from the earlier E8 as built only by the newer engines and a different, flusher-fitting mounting for the headlight glass, the latter being the only visible difference. Since some E8s were fitted with this, it is not a reliable way to distinguish the two. The E9 has two , V12 model 567C engines, each engine driving one generator to power two traction motors. Engine and powertrain The E9 uses twin 12 cylinder 567C engines developing a total of at 800 rpm. Designed specifically for railroad locomotives, this Roots-blown, mechanically-aspirated 2-stroke 45-degree V-type, with an , bore by stroke, giving displacement per cylinder, remained i ...

EMD E8
The E8 is a , A1A-A1A passenger-train locomotive built by General Motors' Electro-Motive Division (EMD) of La Grange, Illinois. A total of 450 cab versions, or E8As, were built from August 1949 to January 1954, 447 for the U.S. and 3 for Canada. 46 E8Bs were built from December 1949 to January 1954, all for the U.S. The 2,250 hp came from two 12 cylinder model 567B engines, each driving a generator to power the two traction motors on one truck. The E8 was the ninth model in the line of passenger diesels of similar design known as EMD E-units. Starting in September 1953, a total of 21 E8As were built which used either the 567BC or 567C engines. In profile the front of the nose of E7, E8, and E9 units is less slanted than earlier EMD units, and E7/8/9s (and their four axle cousins, the F-unit series) have been nicknamed " bulldog nose" units. Earlier E-unit locomotives were nicknamed "slant nose" units. After passenger trains were canceled on the Erie Lackawanna in 1970 ...

EMD E7
The E7 was a , A1A-A1A passenger train locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois. 428 cab versions, or E7As, were built from February 1945 to April 1949; 82 booster E7Bs were built from March 1945 to July 1948. (Circa 1953 one more E7A was built by the Los Angeles General Shops of the Southern Pacific by rebuilding an E2A.) The 2,000 hp came from two 12 cylinder model 567A engines. Each engine drove its own electrical generator to power the two traction motors on one truck. The E7 was the eighth model in a line of passenger diesels of similar design known as EMD E-units, and it became the best selling E model upon its introduction. In profile the front of the nose of an E7A was less slanted than on earlier EMD passenger locomotives, and the E7, E8, and E9 units have been nicknamed “ bulldog nose” units. Some earlier units were called “shovel nose” units or “slant nose” units. In film A Gulf, Mobile and Ohio Railroad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
