The GE three-power boxcabs were early electro-diesel hybrid switcher locomotives. These boxcabs were termed oil battery electrics [1] to avoid the use of the German name Diesel, unpopular after World War I. [2]
The prototype of these locomotives was New York Central 1525 delivered in February 1928. This locomotive had a center-cab design. After successful testing a series of 40 locomotives [1] with boxcab carbodies were built along with the line of the ALCO boxcabs by a consortium of ALCO, General Electric, Ingersoll Rand and Electric Storage Battery. ALCO built the locomotive frame, carbody and running gear, General Electric built the generator, traction motors and controls, Ingersoll Rand provided the diesel engine, and the traction batteries were made by the Electric Storage Battery Co. of Philadelphia (now Exide).
The locomotives were mainly used in city areas for switching work, where exhaust-emissions-free operation was required at spurs entering factory halls. The main batch was ordered by New York Central Railroad to be used in the New York City area operating on the West Side Line and the High Line. Some three-power boxcabs also worked Chicago, Detroit, and Boston. One locomotive was built for Rock Island, which used it for switching the LaSalle Street Station in Chicago.
The principle of operation was similar to that of modern hybrid locomotives, the diesel engine driving a main generator of 600 volts DC, which provided charging current to a bank of batteries which powered four traction motors, one per axle. In addition to being powered by the diesel engine, these locomotives were capable of operating as electric locomotives. Two of these locomotives were equipped to operate off of 3000 volt overhead lines, and 34 were capable of operating off of a 600 volt third rail. The locomotives were equipped with a six-cylinder four-stroke in-line engine of 300 hp (224 kW). The diesel motor was used to charge the batteries, which could not be charged by third rail power. [3] The battery consisted of 240 Exide Ironclad cells with a total capacity of 301 kWh. [4]
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 American Locomotive Company was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants.
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.
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system.
The GE U25B is General Electric's first independent entry into the United States domestic road switcher diesel-electric locomotive railroad market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco.
The U25C is a diesel locomotive built by General Electric intended for the United States domestic market. Launched in September 1963, it remained in production until December 1965. It was replaced by the U28C.
A road switcher locomotive is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere.
Electro-Motive Diesel is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD is now owned by Progress Rail Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel.
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.
The ALCO boxcabs were diesel-electric switcher locomotives, otherwise known as AGEIR boxcabs as a contraction of the names of the builders. Produced by a partnership of three companies, ALCO built the chassis and running gear, General Electric the generator, motors and controls, and Ingersoll Rand the diesel engine. The principle of operation was the same as modern locomotives, the diesel engine driving a main generator of 600 volts DC with four traction motors, one per axle.
The ALCO FA was a family of B-B diesel locomotives designed to haul freight trains. The locomotives were built by a partnership of ALCO and General Electric in Schenectady, New York, between January 1946 and May 1959. Designed by General Electric's Ray Patten, they were of a cab unit design; both cab-equipped lead FA and cabless booster FB models were built. A dual passenger-freight version, the FPA/FPB, was also offered. It was equipped with a steam generator for heating passenger cars.
A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system (RESS), placed between the power source and the traction transmission system connected to the wheels. Since most diesel locomotives are diesel-electric, they have all the components of a series hybrid transmission except the storage battery, making this a relatively simple prospect.
The Union Pacific GTELs were a series of gas turbine-electric locomotives built by Alco-GE and General Electric between 1952-1961 and operated by Union Pacific from 1952 to 1970.
Hermann Lemp born: Heinrich Joseph Hermann Lemp was a Swiss-American electrical engineer; he is credited as the inventor of the modern system of diesel electric traction co-ordination and control.
The GE boxcabs, sometimes also GE IR boxcabs, were diesel-electric switcher locomotives succeeding the ALCO boxcabs. The locomotives were built by General Electric and Ingersoll Rand without ALCO. Production lasted from 1928 to 1930. These boxcabs were often termed oil-electrics to avoid the use of the German name Diesel, unpopular after World War I.
R-Motor was the class designation given by the New York Central one prototype and a later fleet of 42 ALCO-GE built electric freight locomotives for use in the New York Electrified Zone. In conjunction with the P Motors, the Rs marked the second generation of electric locomotives built for the New York Central. Also like the P Motors they used advanced nose suspended traction motors and the R-2s were some of the first North American locomotives to make use of the C-C wheel arrangement, which later became the standard for diesel electric road freight.
Maine Central Railroad began operating diesel locomotives in 1935, and had retired all steam locomotives by 1954. That time interval was a joint operating period with the Boston and Maine Railroad (B&M). This article describes diesel locomotives owned by Maine Central through the period of joint operation and later independent operation prior to Guilford Rail System control in 1981.
The Great Northern Z-1 was a class of ten electric locomotives built for the Great Northern Railway They were used to work the route through the second Cascade Tunnel. They were built between 1926–1928 by Baldwin Locomotive Works, with Westinghouse electrics, and stayed in service until dieselisation in 1956. Each was of 1,830 horsepower (1,360 kW) with a 1-D-1 wheel arrangement, although they were always used in coupled pairs.
