Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 60, pp. 142. Works numbers were 54254-54256 in January 1921.
Curves were a tight 45 degrees or 130 feet (39.6 metres) in radius. Consequently, the wheels on the middle axle were blind (i.e. without flanges).
