Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 30, p. 217. Works number was 30453 in March 1907.
This Consolidation was originally intended for the National Railway of Nicaragua, but was sold to Frazar & Company as agents for the Japanese Bibai Company. Its specifications were essentially identical to locomotives delivered in 1893 (Locobase 10934) and later designated 9040.
