Sandy River 0-4-4 "Forney" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 1005)

Data from [link] (reviewed 13 February 2004) and 1934 Maine Central locomotive tables supplied by Allen Stanley in May 2005 from his extensive Rail Data Exchange. See also [link] (23 May 2004) [link], last accessed 1 July 2017; and Chuck Collins, "Sandy River #4" in the "Prototype Information: the SR&RL locomotives' entry on The Maine On2 FAQ at [link], last accessed 6 July 2024. . Works numbers were 616 in October 1890 and 622 in May 1891.

A modified Hinkley Forney design, the two engines displayed the Forney's strengths and weaknesses. The 4 ran the SR's freight engine for a year. It then pulled passenger trains such as the Rangeley Express. Damaged in an 1897 engine house fire but repaired, the 4 suffered three derailments, the first on a plow train in 1903, then two rollover derailments, one in 1908 owing to excessive speed and a sceond in 1913 as the Sandy River & Rangeley Lakes #5.

Sidelined in 1916, the #5 was sold for scrap in 1919.

SR's #5 first hauled freight on the Phillips & Rangeley, suffering a rollover in 1892. It was damaged in the 1897 engine house fire, repaired, then hit by a standard-gauge engine in December. After a year's service as the Franklin & Megantic's freight engine, it settled into a role in 1900 as the F&M's passenger power for the next 25 years, ( In 1908, the consolidation of 2' lines led to its renumbering as Sandy River & Rangeley Lakes #6.) despite a rollover in 1917.

Beginning in 1925, the #6 went on standby for the Kennebec Central ast their #4 and the Wiscasset, Waterville & Farmington as their #9./ As each railroad closed in 1929 and 1933, erspectively, the 6 survived and was later sold to a private owner in 1937.
