Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University,Vol 78, pp. 262+. Works number was 58548 in July 1925.
See Locobase 15397 for a description of this design. These and several others shown in Locobse 15396 were built as parts of a large order of locomotives for the Sao Paulo Rio Grande.
The 333 was numbered in the SPRG sequence, it would soon join that railway's roster.
