Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21, p.161. Works number was 15832 in April 1898.
A small double-ended, wood-burning saddle tank for the standard gauge, which allowed the grate to reach the usual width of 34 3/8". BHL of Moody, California later became South Humboldt Lumber. The 2 was retired in 1941 and sold in 1979 to Northern Counties Logging Interpretive for possible restoration.
