Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 79, p 147+. Works numbers were 60694-60695 in December 1928.
Little wood-burners described as "switchers" and certainly small enough to discourage very long distance travel on this road. They used Rushton Improved cabbage stacks to catch sparks.
The 4 is described in Gene Connelly's production list as having retired in 1953.
