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.
The Sandy River and Rangeley Lakes Railroad (SR&RL) was a 2 ft narrow gauge common carrier railroad that operated approximately 112 miles (180 km) of track in Franklin County, Maine. The former equipment from the SR&RL continues to operate in the present day on a revived, short segment of the railway in Phillips, Maine.
The Monson Railroad was a 2 ft narrow gauge railway, which operated between Monson Junction on the Bangor and Aroostook Railroad and Monson, Maine. The primary purpose of this railroad was to serve several slate mines and finishing houses in Monson. According to the Scientific American of 17 May 1890, it was the smallest railroad in the United States.
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 Central Massachusetts Railroad was a railroad in Massachusetts. The eastern terminus of the line was at North Cambridge Junction where it split off from the Middlesex Central Branch of the Boston and Lowell Railroad in North Cambridge and through which it had access to North Station in Boston. From there, the route ran 98.77 miles west through the modern-day towns of Belmont, Waltham, Weston, Wayland, Sudbury, Hudson, Bolton, Berlin, Clinton, West Boylston, Holden, Rutland, Oakham, Barre, New Braintree, Hardwick, Ware, Palmer, Belchertown, Amherst, and Hadley to its western terminal junction at N. O. Tower in Northampton with the Connecticut River Railroad.
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.
The Mountain Division is a railroad line that was once owned and operated by the Maine Central Railroad (MEC). It stretches from Portland, Maine on the Atlantic Ocean, through the Western Maine Mountains and White Mountains of New Hampshire, ending at St. Johnsbury, Vermont in the Northeast Kingdom. The line was abandoned in 1983 by MEC's successor, Guilford Transportation Industries (GTI). Guilford retained a stub between Portland and Westbrook. A section in New Hampshire remains in use by heritage railway Conway Scenic Railroad.
The Bucksport Branch is a railroad line in Maine that was operated by the Maine Central Railroad. It is now part of the Pan Am Railways system.
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 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 L locomotives were intended for main line passenger service. They were of 4-4-0 wheel arrangement in the Whyte notation, or "2'B" in UIC classification. They were transferred to branch line passenger service as replaced by class N 4-6-0 locomotives beginning in 1899. Ten numbered 191 to 201 survived United States Railroad Administration operations to appear on a 1923 roster. All were retired between 1925 and 1947 and were scrapped from 1945-1955. None were preserved.
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.
The Sebasticook and Moosehead Railroad was a 19th-century Maine railroad which became the 20th century Harmony Branch of the Maine Central Railroad.
