Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 18, p.196 and Volume 19, p. 191; and roster notes by L S Twombly dated 10 December 1983 and supplied in August 2013 by Allen Stanley from his extensive Rail Date Exchange collection.

The History of the Chicago, Rock Island, & Pacific Railroads, Volume I: The Empire Years: 1850 Up to the Great War (Pittsburgh, PA: Dorrance Publishing Co , 2017) , p. 240. Works number was 13861 in December 1893.
OS RR ordered a total of 16 locomotives locomotives of this basic Mogul design. Only the first four (30-33) of the first batch of eight were delivered to the OS. L S Twombly's notes report that the last four of this batch suffered the effects of the 1893 Depression and were not delivered because of the OS's inability to pay cash.
Of the four not delivered, the nominally numbered 36 went to the Little Rock, Hot Springs & Texas as their #1. The LRHS&T was chartered in 1893 to connect the first two towns in its name over about 60 miles of Pulaski, Saline & Garland counties. Farnsworth's account describes the shoestring financing that eventually doomed the railroad to undergo reorganization in 1899 as the Little Rock & Hot Springs Western. It never made it to Texas.
But the 1 arrived in the Lone Star State in August 1896 when it was sold to the Galveston, La Porte & Houston as their #6 (and later the Galveston, Houston & Northern). In 1905, the Texas & New Orleans subsidiary of the Southern Pacific bought the #6 and renumbered it #409 in class M-3.
It was retired in 1932 and scrapped in 1935.
