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. [1]
All were built in American Locomotive Company's plant at Schenectady, New York and were numbered from 450 to 470 as delivered. The original C class were builders numbers 42439 & 42440 delivered in 1907, 46036-46038 in 1909, 47731 in 1910, and 49205-49206 in 1911. Sub-class C-1 consisted of builders numbers 50940 & 50941 built in 1912, and 52985-52986 & 53291 completed in 1913. Builders numbers 54568 through 54570 arrived in 1914 as sub-class C-2 with weight increased to 238,500 lb (108.2 tonnes). [2]
The last five Maine Central Pacifics were built with booster engines. Increasing cylinder diameter to 24 inches (610 mm) increased tractive effort to 36,500 lbf (162.4 kN) or 46,800 lbf (208.2 kN) with the booster. Enlarged tenders held 13 tons of coal and 9,100 US gal (34 m3) of water. Builders numbers 57885 through 57887 were delivered in 1917 with weight increased to 268,300 lb (121.7 tonnes). Building of new 4-6-2s was interrupted by World War I when the United States Railroad Administration (USRA) authorized construction of non-standard class O 4-6-0s because Maine Central Pacifics were so much smaller than USRA Light Pacifics. The final two class C engines were builders numbers 65554 and 65555 delivered in 1924. [3] Number 470 was preserved in Waterville, Maine after pulling the last Maine Central steam-powered train on 13 June 1954. [4]
The last steam locomotives built for Maine Central were class D 4-6-4s numbered 701 and 702 from Baldwin Locomotive Works in 1930. [1] The Budd Company Flying Yankee train set and unstreamlined 600 horsepower (450 kW) oil-electric rail car number 901 arrived in 1935. EMD E7s numbered 705 through 711 began pulling main line passenger trains in 1946. Steam-generator-equipped road switchers pulled a declining number of branch line passenger trains from 1950 until Maine Central discontinued all passenger service in 1960. [5]
Under the Whyte notation for the classification of steam locomotives, a 2-10-4 locomotive has two leading wheels on one axle, usually in a Bissel truck, ten coupled driving wheels on five axles, and four trailing wheels on two axles, usually in a bogie. These were referred to as the Texas type in most of the United States, the Colorado type on the Burlington Route, and the Selkirk type in Canada.
Under the Whyte notation for the classification of steam locomotives, 4-8-4 represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern.
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.
Under the Whyte notation for the classification of steam locomotives, 2-10-2 represents the wheel arrangement of two leading wheels, ten powered and coupled driving wheels, and two trailing wheels. In the United States and elsewhere the 2-10-2 is known as the Santa Fe type, after the Atchison, Topeka and Santa Fe Railway that first used the type in 1903.
Under the Whyte notation for the classification of steam locomotives, 2-6-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels. This arrangement is commonly called a Mogul.
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.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-6-6-2 is a locomotive with one pair of unpowered leading wheels, followed by two sets of three pairs of powered driving wheels and one pair of trailing wheels. The wheel arrangement was principally used on Mallet-type articulated locomotives, although some tank locomotive examples were also built. A Garratt locomotive or Golwé locomotive with the same wheel arrangement is designated 2-6-0+0-6-2 since both engine units are pivoting.
The Portland Terminal Company was a terminal railroad notable for its control of switching (shunting) activity for the Maine Central Railroad (MEC) and Boston & Maine (B&M) railroads in the Maine cities of Portland, South Portland, and Westbrook.
Pennsylvania Railroad Class L1s were 2-8-2 "Mikado"-type steam locomotives that were used on the Pennsylvania Railroad during the early twentieth century. These 574 locomotives were manufactured between 1914 and 1919 by the railroad's own Juniata Shops as well as the Baldwin Locomotive Works (205) and the Lima Locomotive Works (25).
The USRA Light Pacific 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. It was the standard light passenger locomotive of the USRA types, with a 4-6-2 wheel arrangement in the Whyte notation, or 2′C1′ in UIC classification.
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 steam switchers were designated Class K. They were of 0-6-0 wheel arrangement in the Whyte notation, or "C" in UIC classification. American Locomotive Company (ALCO) began building more powerful yard locomotives for Maine Central in 1909. Twenty locomotives numbered 161 through 180 were active in 1923, and worked in Maine's largest cities until replaced by diesels 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 switcher locomotives. 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.
Maine Central 470 is a 4-6-2 "Pacific" type steam locomotive built by the American Locomotive Company (ALCO) in May 1924 for the Maine Central Railroad (MEC). Currently owned by the New England Steam Corporation, it is being restored to operating condition at Washington Junction in Hancock, Maine.
Atlantic Coast Line 1504 is a 4-6-2 steam locomotive built in March 1919 by American Locomotive Company (ALCO) of Richmond, Virginia, for the Atlantic Coast Line Railroad (ACL) as a member of the P-5-A class under the United States Railroad Administration (USRA) standard. No. 1504 was assigned to pull ACL's premier main line passenger trains during the 1920s to early 40s and even secondary passenger trains and main line freight trains in the late 1940s until it was retired from revenue service at the end of 1952.
The Norfolk and Western Y3 Class was a class of 2-8-8-2 "Mallet" articulated steam locomotives with a total of 80 locomotives built for the Norfolk and Western Railway between 1919 and 1923.
