The American Locomotive Company was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969.
The Philippine National Railways (PNR) is a state-owned railway company in the Philippines which operates one commuter rail service between Metro Manila and Laguna, and local services between Sipocot, Naga City and Legazpi City in the Bicol Region. It is an attached agency of the Department of Transportation.
A diesel locomotive is a type of railway locomotive in which the prime mover 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.
A cowl unit is a body style of diesel locomotive. The terminology is a North American one, though similar locomotives exist elsewhere. A cowl unit is one with full-width enclosing bodywork, similar to the cab unit style of earlier locomotives, but unlike the cab unit style, the bodywork is merely a casing and is not load-bearing. All the strength is in the locomotive's frame, beneath the floor, rather than the bridge-truss load-bearing carbody of the earlier type.
A hood unit, in North American railroad terminology, is a body style for diesel and electric locomotives where the body is less than full-width for most of its length and walkways are on the outside. In contrast, a cab unit has a full-width carbody for the length of the locomotive and walkways inside. A hood unit has sufficient visibility to be operated in both directions from a single cab. Also, the underframe is the main load-bearing member, allowing the hood to be non-structural and easily opened or even removed for maintenance.
In North American railroad terminology, a cab unit is a railroad "locomotive" with its own cab and controls.
The GE AC4400CW is a 4,400 horsepower (3,300 kW) diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. It is like the Dash 9-44CW, but features AC traction motors instead of DC, with a separate inverter per motor. In appearance, the AC4400CW is somewhat similar to GE's more powerful locomotive, the AC6000CW.
Dieselisation is the process of equipping something with a diesel engine or diesel engines. It can involve replacing an internal combustion engine powered by petrol (gasoline) fuel with an engine powered by diesel fuel, as occurred on a large scale with trucks, buses, farm tractors, and building construction machinery after the Second World War. Alternatively it can involve replacing the entire plant or vehicle with one that is diesel-powered; the term commonly describes the generational replacement between the 1930s and the 1970s of steam locomotives with diesel locomotives, and associated facilities.
A boxcab, in railroad terminology, is a locomotive in which the machinery and crew areas are enclosed in a box-like superstructure. It is a term mostly used in North America while in Victoria (Australia), such locomotives have been nicknamed "butterboxes". Boxcabs may use any source of power but most are diesel or electric locomotives. Few steam locomotives are so described but the British SR Leader class was a possible exception. Most American boxcabs date from before World War II, when the earliest boxcabs were often termed "oil-electrics" to avoid the use of the German name "Diesel" due to propaganda purposes.
The GE Universal Series locomotives were diesel locomotives originally launched by GE in early 1956. The latest variant in the Universal Series was built in 2005. Initially, there were nine U-series models: U4B, U6B, U9B, U9C, U12B, U12C, U18B, U18C and UD18B. They were designed to be readily adaptable to different track gauges for export markets and very reliable. The U5B and U8B appeared later, being first built for RFFSA, Brazil in 1961.
The South African Railways Class 34-500 of 1974 is a diesel-electric locomotive.
The PNR 900 class of 1973 are GE Universal Series Diesel-Electric Locomotives in service with the Philippine National Railways. Initially used for long-distance express services throughout Luzon, they were relegated to hauling commuter trains within Metro Manila, a task previously done by PNR's diesel multiple units fleet. This was further exacerbated by the closure of the PNR South Main Line's intercity section in 2012 after an accident in Sariaya, Quezon.
The PNR South Main Line is one of the two trunk lines that form the Philippine National Railways' network in the island of Luzon, Philippines. It was opened in stages between 1916 and 1938 by the Manila Railroad. Services peaked in the 1940s until the late 1960s, when the system started to decline. Since 1988, it was the only functioning inter-city rail after its counterpart to the north, the North Main Line, was closed. The intercity section of the line in Laguna, Quezon and the Bicol Region was then closed and reopened repeatedly between 2004 and 2014 due to a combination of declining ridership and was closed since then. Currently, only two short sections of the line survive; the PNR Metro Commuter Line between Tutuban station and Laguna, and the Bicol Commuter regional rail service between Sipocot and Naga, Camarines Sur.
The Manila Railroad 45 class of 1919 were twenty-one 4-6-0 Ten-wheeler steam locomotives. Twenty locomotives were built by American light duty locomotive manufacturer H.K. Porter, Inc. between 1919 and 1921 for the Manila Railroad Company (MRR). The so-called Porters were the most successful steam locomotive class in Philippine service. They carried express trains for passengers as well as short-range maintenance trains for 70 years and served both the MRR and its successor, the Philippine National Railways. However, like all tender engines from the Manila Railroad era, the last locomotive was scrapped in the 1990s without a single unit preserved.
The Manila Railroad 200 class were 2-10-2 Santa Fe steam locomotives operated by the Manila Railroad Company (MRR), predecessor of the Philippine National Railways. They were built alongside the 4-8-2 Mountain-type 170 class by the American Locomotive Company at its Brooks facility between 1921 and 1922. During its service at the MRR, it carried heavy freight trains on the South Main Line between Manila and the Bicol Region.
The Manila Railway Dagupan class of 1890 were thirty 0-6-2 side tank locomotives. Thirty locomotives were built for the Manila Railway Company between 1888 and 1890. They were the first true mainline locomotives in service of the Ferrocarril de Manila a Dagupan inter-city rail line, succeeding two of five Manila class light-duty locomotives. One of these locomotives, No. 17 Urdaneta, survives today on static display on an open-air museum in Dagupan, Pangasinan.
The Manila Railroad 170 class were ten 4-8-2 Mountain steam locomotives operated by the Manila Railroad Company (MRR), predecessor of the Philippine National Railways. They were built alongside the 2-10-2 Santa Fe-type Manila Railroad 200 class by the American Locomotive Company at its Brooks facility between 1921 and 1922. During its service at the MRR, it carried passenger trains on the South Main Line between Manila and the Bicol Region.
The Manila Railway 70 class of 1908 were at least twenty 0-6-2 combination side- and well-tank locomotives built by the North British Locomotive Company. It was first operated as mainline locomotives in the late 1900s and early 1910s by the Manila Railway Company, primarily to support its growing network and replace the aging Dagupan class engines. They were used on all the lines of the networks of both the Manila Railway and its succeeding incarnation, the Manila Railroad. Since the 1920s, some locomotives were retired then either scrapped or given to sugarcane plantations. The last unit, No. 79, survived with the Pampanga Sugar Development Company as late as 1989.
