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 this tank 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 9 years of service, the 162 was scrapped in September 1916.
