Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 49, p. 128, Vol 54, pp. 319+; and Vol 66, pp. 103+. Works numbers were 40544 in September 1913, 43336 in May 1916, 51201 in February 1919.
Locobase 13467 gives a brief account of the Norte's origins and original intentions, noting that the actual railway was relatively short. Even so, the company chose a superheated Consolidation design in 1913 and added sister engines in 1916 and 1919.
