Data from Baldwin Locomotive Works datacard as digitized by the DeGolyer Library of Southern Methodist University, Volume 47, p. 273. See also the Tapline Case Summaries site at []. Works number was 38315 in September 1912.
This logging line ran from Warren to Hermitage, Ark and covered 15.6 miles, not counting the 5-mile branch line to Johnsville and the logging trails that amounted to another 15 miles. The WJ&SR was owned by the Bradley Lumber Company. The TapLines Case assessment underscored how specialized the railroad was: "The country through which the tap line runs is a wilderness, the only towns being Warren and Hermitage, the respective junction points with the trunk lines. There is very little traffic except that supplied by the lumber company, although it is stated that there are one or two short spurs used by independent producers of staves, bolts, and ties, and there is an occasional movement of fertilizer or cottonseed. "
This low-drivered Ten-wheeler was therefore perfectly suited to the WJ&SR's requirements, even after it reorganized as the Warren & Saline River in 1920.
