Walter H Gahagan 4-6-0 "Ten-Wheeler" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 13334)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 32, p. 51 and 311. Works numbers were 33013-33014 in October 1908 and 33255-33256 in March.

Gahagan was a large construction company that worked on civil-engineering projects across the country. Baldwin supplied two wheel arrangements to the company: this quartet of small Ten-wheelers and six 0-4-0 switchers.

All of the 4-6-0s were sold to other industrial or logging operators after a period in Gahagan service. The 1 went to the Isle d'Anticosti in Quebec's Gulf of St Lawrence and was used in logging operations. 2's first stop was locomotive rebuilder/reseller Birmingham Rail & Locomotive. BR & L sold the engine to Gulledge Lumber Company of Haines City, Fla, passed quickly to International Paper, and wound up with Polk City Lumber in 1927. 3 was sold to Warner Sugar Refining Company in Waukegan, Ill. 4 went to Wickwire Steel of Buffalo, NY by 1917.
