Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 24, p. 194. Works number was 20159 in February 1902.
The B & A Short Line didn't prosper during its steam era, the fault for which cannot be laid at the drivers of this small, but unremarkable Eight-wheeler. After electrification, the B & A operated for decades as an interurban. After buses took over passenger traffic in 19050, the B & A continued to run freight trains. Eventually the line was absorbed by the Maryland Transit Administration.
Part of the right-of-way regained its purpose in the 1990s and beyond when the Baltimore light-rail line system ran trains down to Glen Burnie.
