Eustis / Franklin & Megantic / Sandy River & Rangely Lakes 0-4-4 "Forney" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 7 (Locobase 1009)

Data from (reviewed 13 Feb 2004) and 1934 Maine Central locomotive tables supplied by Allen Stanley in May 2005 from his extensive Raildata collection. See also DeGolyer, Volume 26, p. 44. Works numbers were 23245 in December 1903 and 23254-23255 in February 1904.

There was enough time between the delivery of the first engine and shipment of the others to ask for some changes. The side windows needed to slide and the cab should have doors. The grate now had rocking bars and drop plates and the blower valve would get a dry pipe leading to the dome.

20 was abandoned in 1922, 21-22 were stored in the early thirties.

Class N B Beal (Locobase 1005)

Data from (reviewed 13 Feb 2004) and 1934 Maine Central locomotive tables supplied by Allen Stanley in May 2005 from his extensive Raildata collection. See also (23 May 2004). Works numbers were 622 in May 1891.

Class S W Sargent (Locobase 1004)

Data from (reviewed 13 Feb 2004) and Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University Volume 13, p.158. Works number was 8304 in December 1886.

This 14 1/2-mile railway penetrated northern Maine's forests from Strong through Kingfield and ending at Bigelow. Opened in 1884, one of its first purchases was this little tank. Over the next 20 years, the F & M gradually wound its way north, running its own trains and hosting trains from the Sandy River Railroad. One outcome was the renumbering of the 2 to 3 to avoid duplication.

The Sandy River & Rangeley Lakes bought the line in 1908 and renumbered the aging 3 as their #4. In September 1912, #4 was scrapped at Phillips.
