Fernwood & Gulf 2-8-2 "Mikado" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 13 (Locobase 12597)

Data from Baldwin Logging Locomotives 1913 Catalogue, p.48. See also DeGolyer, Volume 45, p. 67. Works number was 40734 in October 1913.

Logging Mikados had big boilers and relatively big grates and, perhaps most important, a light rail loading. This F & G 2-8-2 was no exception. The F&G offered a maximum of 1.5% grade and 16-degree curves (383 ft/117 metre radii); its most challenging section consisted of a 1.2% combined with a 4-degree curve. Still, the specs also show that the F&G asked Baldwin to make the Hodges outside rear truck more flexible and to shorten the boiler.

The F&G was later reorganized as the Fernwood, Columbia & Gulf when the railroad reached Columbia.

The 13 would later be operated by three other timber harvesters: Apollonia Lumber Co. of Pelahatchie, Miss; Natalbany Lumber Co, headquartered in Natalbany, LA; and Jahncke Service Co. in Bluff Creek, LA
