A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight trains.
The ALCO Century Series locomotives were a line of road switcher locomotives produced by Alco, the Montreal Locomotive Works and AE Goodwin under license in Australia.
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
The GE U50 was an eight-axle, 5,000 hp (3,700 kW) diesel-electric locomotive built by GE Rail. They were twin-engined locomotives, combining two 2,500 hp (1,900 kW) diesel engines.
The Consolidation Line was a series of diesel-electric railway locomotive designs produced by Fairbanks-Morse and its Canadian licensee, the Canadian Locomotive Company. Railfans have dubbed these locomotives “C-liners”, however F-M referred to the models collectively as the C-Line. A combined total of 165 units were produced by F-M and the CLC between 1950 and 1955.
An electro-diesel locomotive is a type of locomotive that can be powered either from an electricity supply or by using the onboard diesel engine. For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose.
Railpower Technologies is a subsidiary of R.J. Corman Railroad Group that builds environmentally friendly hybrid Green Goat and Genset switching locomotives, founded by Frank Donnelly and Gerard Koldyk. Its locomotives have been purchased by Canadian Pacific Railway, BNSF Railway, Kansas City Southern Railway and Union Pacific Railroad among others.
The ALCO RSD-1 was a diesel-electric locomotive built by the American Locomotive Company (ALCO). This model was a road switcher type rated at 1,000 horsepower (750 kW) and rode on three-axle trucks, having a C-C wheel arrangement. It was often used in much the same manner as its four-axle counterpart, the ALCO RS-1, though the six-motor design allowed better tractive effort at lower speeds, as well as a lower weight-per-axle. It was developed to meet the need to supply the Soviet Union over the Trans-Iranian Railway starting in mid 1943. On the other hand, due to the traction generator and appurtenant control apparatus being sized for four axles and yet having two additional powered axles, it had poorer performance at higher speeds.
The FM H-12-44TS was a light road switcher version of the Fairbanks-Morse H-12-44 yard switcher locomotive. Only three of the 1,200-horsepower (890 kW), six-cylinder opposed piston engine locomotives were manufactured especially for the Atchison, Topeka and Santa Fe Railway in May, 1956. The units had an extended frame to accommodate the addition of a short hood behind the cab, and were configured in a B-B wheel arrangement and mounted atop a pair of two-axle AAR Type-A switcher trucks with all axles powered. H-12-44TSs also came equipped with steam generator units as they were acquired solely for shuttling passenger cars in and around the Dearborn Station terminal in Chicago, Illinois.
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 2,250 hp and used the 244G engine. The revised specification DL-600A, numbering 27 locomotives, was rated at 2,400 hp 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.
The FM H-15-44 was a diesel locomotive manufactured by Fairbanks-Morse from September 1947 to June 1950. The locomotive was powered by a 1,500-horsepower (1,100 kW), eight-cylinder opposed piston engine as its prime mover, and was configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type-B road trucks with all axles powered. The H-15-44 featured an offset cab design that provided space for an optional steam generator in the short hood, making the model versatile enough to work in passenger service as well as freight duty.
The Alco S-5 was a diesel-electric switcher locomotive rated at 800 horsepower (600 kW), that rode on two-axle trucks, having a B-B wheel arrangement.
The ALCO DL420 was the prototype ALCO S-5 diesel-electric switcher locomotive.
The Baldwin RS-4-TC is a diesel-electric switcher locomotive built by the Baldwin-Lima-Hamilton Corporation between July 1953 and January 1955. The RS-4-TCs were powered by a supercharged twelve-cylinder diesel engine rated at 400 horsepower (298 kW), and rode on a pair of two-axle trucks in a B-B wheel arrangement. 74 of these models were built mainly for the Army while a few of them went to the Air Force.
The Baldwin DRS-6-4-1000 is a diesel-electric locomotive built by Baldwin Locomotive Works between 1948 and 1949. The DRS-6-4-1000s were powered by a turbo-charged six-cylinder diesel engine rated at 1,000 horsepower (746 kW), and rode on a pair of three-axle trucks in an A1A-A1A wheel arrangement. 20 of these models were built for a railroad in Algeria.
The Baldwin DRS-6-4-660, known in France as the A1AA1A 62000, is a road switcher diesel-electric locomotive built by Baldwin Locomotive Works between 1946 and 1948. The DRS-6-4-660s were powered by a naturally aspirated six-cylinder diesel engine rated at 660 horsepower (492 kW), and rode on a pair of three-axle trucks in an A1A-A1A wheel arrangement. 106 of these models were built for railroads in Morocco and France.
The Railpower GG20BGreen Goat is a low-emissions diesel hybrid switcher locomotive built by Railpower Technologies Corp. It is powered by a single Caterpillar C9 six cylinder inline engine developing 300 horsepower (224 kW), which is also connected to a large battery bank where both sources combine for a total power output of 2,000 horsepower (1,490 kW). To date, there have been more than 50 GG20B diesel-electric hybrid switchers manufactured since their first introduction in 2004.
The RP20BD is a diesel-electric switcher locomotive built by Railpower Technologies. It is a "genset" locomotive, having three engine-generator sets.
The RP14BD is a diesel-electric switcher locomotive built by Railpower Technologies. It is a "genset" locomotive, having two engine-generator sets.
Baldwin, the locomotive manufacturer, and Westinghouse, the promoter of AC electrification, joined forces in 1895 to develop AC railway electrification. Soon after the turn of the century, they marketed a single-phase high-voltage system to railroads. From 1904 to 1905 they supplied locomotives carrying a joint builder's plate to a number of American railroads, particularly for the New Haven line from New York to New Haven, and other New Haven lines. Westinghouse would produce the motors, controls, and other electrical gear, while Baldwin would produce the running gear, frame, body, and perform final assembly.
