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.[1]
All were built in American Locomotive Company's plant at Schenectady, New York. The first nine built in 1910 (builders numbers 47732-47736 & 49207-49210) were 5,000 pounds (2,300 kg) lighter than the infobox figure. Sub-class W-1 consisted of seven locomotives added in 1912 (builders numbers 50933-50939) and eight more (builders numbers 52989-52996) delivered in 1913. The last four designated sub-class W-2 (builders numbers 54564-54567) were delivered in 1914 and were 4,000 pounds (1,800 kg) heavier than the infobox figure.[1]
