Data from Baldwin Locomotive Works Specification for Engines, 1890, as digitized by the DeGolyer Library of Southern Methodist University Vol 20, p. 38. Works numbers were 14494 in October 1895 and 14955 in July 1896.
These locomotives were identical except that the 4 had bigger side tanks that held 1,600 gallons of water.
The RF & RL covered 38.7 miles of standard gauge from Rumford, where it met with its parent Portland & Rumford Falls, to Kennebago farm on the shore of Lake Mooselucmaguntic.
In 1903, the Portland & Rumford Falls renumbered these tanks 51-52. Four years later, the Maine Central leased the P & RF and RF & RL for 999 years, which resulted in another renumbering.
The MEC didn't hang on to 112, selling it to International as their #6 in September 1907. 113 remained with the railroad until it was scrapped in May 1919.

In 1903, Portland & Rumford Falls renumbered the 2 as 53. In 1907, Four years later, the Maine Central leased the P & RF and RF&RL for 999 years, which resulted in another renumbering. Unlike the 2-6-2T shown in Locobase 12169, however, the MEC held onto the 162, converting it to a 2-6-2T and placing in its own class F.
After another nine years of service, the 162 was scrapped in September 1916.
