The American Locomotive Company was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969.
Under the Whyte notation for the classification of steam locomotives, 2-10-0 represents the wheel arrangement of two leading wheels on one axle, ten powered and coupled driving wheels on five axles, and no trailing wheels. This arrangement was often named Decapod, especially in the United States, although this name was sometimes applied to locomotives of 0-10-0 "Ten-Coupled" arrangement, particularly in the United Kingdom. Notable German locomotives of this type include the war locomotives of Class 52.
The Schenectady Locomotive Works built railroad locomotives from its founding in 1848 through its merger into American Locomotive Company (ALCO) in 1901.
Under the Whyte notation for the classification of steam locomotives, 2-8-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s Consolidation, the name of the first 2-8-0.
Locomotive classification on the Pennsylvania Railroad took several forms. Early on, steam locomotives were given single-letter classes. As the 26 letters were quickly assigned, that scheme was abandoned for a more complex system. This was used for all of the PRR's steam locomotives, and — with the exception of the final type bought — all electric locomotives also used this scheme.
The USRA 0-6-0 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light switcher locomotive of the USRA types, and was of 0-6-0 wheel arrangement in the Whyte notation, or "C" in UIC classification.
The USRA 0-8-0 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard heavy switcher locomotive of the USRA types, and was of 0-8-0 wheel arrangement in the Whyte notation, or "D" in UIC classification.
The USRA 2-6-6-2 is a standardized design of 2-6-6-2 Mallet locomotives developed by the United States Railroad Administration during World War I.
The Russian locomotive class Ye, and subclasses Yea, Yek, Yel, Yef, Yem, Yemv and Yes were a series of 2-10-0 locomotives built by American builders for the Russian railways in World War I and again in World War II. They were lightweight engines with relatively low axle loadings.
Maine Central Railroad Class W locomotives were intended for heavy freight service. They were of 2-8-0 wheel arrangement in the Whyte notation, or "1'D" in UIC classification. They replaced earlier class O 4-6-0 locomotives beginning in 1910. They were in turn replaced by class S 2-8-2 locomotives for the heaviest freight service beginning in 1914, but remained in use on lighter freight trains until replaced by diesel locomotives after World War II.
Maine Central Railroad Class S locomotives were intended for heavy freight service. They were of 2-8-2 wheel arrangement in the Whyte notation, or " 1'D1' " in UIC classification. They replaced earlier class W 2-8-0 locomotives beginning in 1914. They were the largest and most modern steam freight locomotives built for Maine Central; although former Boston and Maine Railroad 2-10-2s were later purchased to handle World War II freight traffic. Class S locomotives pulled freight trains over the main line between Portland and Bangor, Maine; and are best remembered for service on the Mountain Division from 1929, when the class X Mallet locomotives were scrapped, until replacement by diesel locomotives in the early 1950s.
Maine Central Railroad Class O locomotives were originally intended for heavy freight service. They were of 4-6-0 wheel arrangement in the Whyte notation, or "2'C" in UIC classification. They replaced earlier class P 2-6-0 locomotives beginning in 1903. They were in turn replaced by class W 2-8-0 locomotives for the heaviest freight service beginning in 1910, but remained in use on branch line trains until replaced by diesel locomotives after World War II. They proved so well-suited for branch line service the design was among the last steam locomotives built for the Maine Central.
Maine Central Railroad Class H locomotives were intended for branch line passenger service. They were of 4-4-0 wheel arrangement in the Whyte notation, or "2'B" in UIC classification. Built by the American Locomotive Company's (ALCO) Manchester in 1898 the last were completed at ALCO's Schenectady, New York plant in 1898 all were scrapped between 1916 and 1921. None of the Maine Central Class H 4-4-0 were preserved.
Maine Central Railroad Class N locomotives were intended for main line passenger service. They were of 4-6-0 wheel arrangement in the Whyte notation, or "2'C" in UIC classification. All were built at the Schenectady Locomotive Works which became the American Locomotive Company (ALCO) in 1901. They replaced earlier class L 4-4-0 locomotives beginning in 1899. They were transferred to branch line passenger service as replaced by class C 4-6-2 locomotives beginning in 1907. Most were scrapped during the Great Depression and none survived World War II.
Maine Central Railroad Class C locomotives were intended for main line passenger service. They were of 4-6-2 wheel arrangement in the Whyte notation, or " 2'C1' " in UIC classification. They replaced earlier class N 4-6-0 locomotives beginning in 1907. Class C locomotives pulled named passenger trains until replacement by diesel locomotives after World War II.
Maine Central Railroad Class M locomotives were originally intended for heavy freight service. They were of 2-6-0 wheel arrangement in the Whyte notation, or "1'C" in UIC classification. They were replaced by class P 2-6-0 locomotives for the heaviest freight service beginning in 1896, and spent their final years as yard switchers. The oldest of the class surviving past United States Railroad Administration operation were Portland Company builders numbers 606 and 607 built in 1890. Eleven built by Schenectady Locomotive Works in 1893 and 1894 also appeared in the 221-245 number sequence on Maine Central's 1923 locomotive roster. The longest surviving representatives of the class were three built by Schenectady in 1897 as Portland and Rumford Falls Railway numbers 10 through 12. These three were rebuilt with higher-pressure boilers in Maine Central's Waterville shop between 1914 and 1921 as sub-class M-5. These reboilered locomotives with 25,000 lbf (111.2 kN) tractive effort were numbered 246 through 248. Number 247 was the last survivor of the class when scrapped in 1946.
Maine Central Railroad Class P locomotives were originally intended for heavy freight service. They were of 2-6-0 wheel arrangement in the Whyte notation, or "1'C" in UIC classification. They replaced class M 2-6-0s for the heaviest freight service beginning in 1896. They were transferred to branch line service as replaced by class O 4-6-0 locomotives beginning in 1903. Most were scrapped during the Great Depression and none survived World War II.
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.
Canadian National Railway (CN) Class O-19 steam locomotives were of 0-6-0 wheel arrangement in the Whyte notation, or " C " in UIC classification. These USRA 0-6-0 locomotives were built for the Grand Trunk Railway (GT) in 1919 and remained in yard service until the final replacement of steam with diesel locomotives. ALCO builders numbers 60187 through 60191 were built at the Cooke plant as Grand Trunk Western Railroad numbers 1744 through 1748 while builders numbers 61298 through 61302 were built at the Schenectady, New York plant numbered 1824 through 1828 for use on New England lines. The locomotives were renumbered from 7522 through 7531 under Canadian National control, but retained Grand Trunk lettering for service in the United States.
The China Railways TH10 class steam locomotive was a class of 4-6-0 passenger steam locomotives operated by the China Railway. Originally amongst the first locomotives ordered by the South Manchuria Railway (Mantetsu), they were later operated by the privately owned Jichang Jidun Railway and its successor, the Manchukuo National Railway, which designated them Tehoni class. The "Teho" name came from the American naming system for steam locomotives, under which locomotives with 4-6-0 wheel arrangement were called "Ten-Wheeler".
