Data from Logging Locomotives 1913 (Philadelphia, Pa: Baldwin Locomotive Works, 1913), p 33. See also DeGolyer, Volume 48. p. 315. (Thanks to Chris Hohl for his 9 May 2015 calling my attention to the Baldwin specs pages in Volume 48 of the digitized records archived by SMU's DeGolyer Library.) Works number was 40081 in June 1913.
This little Prairie, one of the typical Baldwin light logging Prairies built in the 19teens) hauled carloads of cedar, cypress, and juniper logs on 30 lb/yard (15 kg/metre) rail from the Dismal Swamp to the RCW's Camden, Virginia saw mills for more than 30 years. An indication of the tight alignments the 10 encountered is the short adhesion wheelbase, the 3" (76 mm) swing to either side in the front truck and 3 1/2" (88 mm) in the rear truck.
Although the road itself was closed to common carriage in 1950, a 1948 photograph suggests the 10 had been idled before then when the tracks were pulled up.
