Class Details by Steve Llanso of Sweat House Media

Class 61 (Locobase 12870)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 173.. Works numbers were 27069-27070, 29763, 29792-29793 in December 1906.

The first two of the 5 locomotives in the 1905 order were lettered for the Darien & Western. This short line curved northwest in an arc from Darien, Ga near the Atlantic to Ludowici by 1904. Before the next trio could be delivered, the D & W had been merged with the Reidsville & Southeastern and the Collins & Reidsville to form the GC & P. This latter's nickname was "Gopher, Coon & Possum". It eventually amassed 99 miles.

Quite probably it was the 18-mile extension south from Darien to Brunswick over two rivers (the Darien and the Altamaha) in March 1914 that irretreviably weakened the almagamated line. In any event the GC & P went into receivership in the next year and was sold off in 1919. Most of the trackage -- including the Brunswick-Darien segment -- was pulled up, although the 23-mile Collins-Glennville section remained in service under other names until 1941. Known first as the Collins & Ludowici, then the Collins & Glennville, the line retianed the 64

The locomotives were all sold to locomotive rebuilder/reseller Georgia Car & Locomotive. 62 went to C Crane & Company of Huntington, WVa in July 1918 as #6, 63 to Lyon Lumber of Garyville, La in August 1918, 61 went to Jacobi Lumber Company of Molino, Fla in June 1919. 65 was sold to Brooks Scanlon in Carbur, Fla in July 1919, but soon journeyed to Burton Swartz Cypress Company.
