Data from the T&NO 3 -1932 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Vol 73, p. 364+. Works number was 58268 in May 1925.
When Tatum Lumber Company finally gained the ICC's approval for its purchase of the branch line that would be known as the B&HS, it immediately ordered some new locomotives. Passenger power on the the 27-mile line was this superheated Eight-wheeler costing $19,285, which admitted steam to its cylinders through 8" (203 mm) piston valves. The design appears to have been derived from a quintet of San Antonio & Aransas Pass locomotives produced in November 1924 (see Locobase 8653).
Its classic profile served the B&HS until 1953, when the TLC sold the branch to fellow Tatum subsidiary Fernwood, Columbia & Gulf and sent the 200 to the ferro-knacker.
