Lafayette 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 12675)

Data from Baldwin Locomotive Works datacard as digitized by the DeGolyer Library of Southern Methodist University, Volume 25, p. 262. Works number was 22097 in May 1903.

Locobase can't seem to identify the purchaser, although it seems to have been a Georgia railroad that covered 22 mile. But when the LRR was abandoned, the engine was sold to the Chattahoochee Valley. Later, the 3 was sold to the locomotive rebuilder/reseller Georgia Car & Locomotive. After its reconditioning, the 3 was sold to Caroline Stone Company of Pageland, SC.
