Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899). (Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.) Works numbers were 2948-2950 in April 1898 and 3275 in July 1899.
The Washington County Railroad Company ran in Maine as an independent line until its takeover by the Maine Central in 1911. According to a list compiled by Mr. Bradley L. Peters in 1976 and preserved on [Data from "Locomotive Building," The Railroad Gazette, Vol XLI, No 9 (31 August 1906), p. 56. Works numbers were 41438-41439 in October 1997.
This Maine short line connected the town of Oakland on the Maine Central to Moosehead Lake (passing Moxie Pond on the way). The lake was a major attraction for nature-loving excursionists. According to 8th-grade Morgan Hisler's hist orry of the Somerset (in the Main Memory Network at [Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 20, p. 40. Works number was 144489 in October 1895.
The P&RF was based in Rumford, Maine and grew steadily. Its location and traffic levels led the Maine Central in 1907 to lease it and the Rumford Falls & Rangeley Lakes for 999 years. This Eight-wheeler served both railroads until the MEC scrapped it in December 1911.Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 28-29. Works numbers were 4224-4228 in November 1894.
Schenectady's catalogue says that the engine was "...in service on the fast heavy seaside passenger trains between Portland and Bar Harbor, Me."
