Gulf, Sabine & Red River 4-6-0 "Ten-wheeler" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 9 (Locobase 13498)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 33, p.1. See also W T Block, "Part E [of Orange County Sawmills and Their History]: The Lutcher and Moore Lumber Company" archived at and Block, "The Sanders-Trotti Tram Company and the Gulf, Sabine and Red River Railroad," at, both last accessed 24 November 2011. Works number was 33424 in May 1909.

Lutcher and Moore Lumber Company was one of the biggest in southeastern Texas when it bought this Ten-wheeler from Baldwin's stock (i.e., locomotives built on "spec"). It was a standard logging 4-6-0 that had sisters operating on roads all over the country.

After its construction in 1893, the GS & RR grew into the largest tram road in Southwest. (A tram road was dedicated to logging and did not need to meet common-carrier standards.) By 1905, says Block in his history, "...the equipment of the Gulf, Sabine and Red River Railroad included 100 miles of main tracks and laterals, ten locomotives, and 151 log cars, making it certainly one of the biggest logging trams in the nation."

Block says that the GS & RR lands held enough to continue logging "at full pace" until 1920, after which the decline happened quickly.
