Texas, Arkansas & Louisiana 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 13028)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p. 235. Works number was 29762 in December 1906. See also Cecil Harper, Jr., "TEXAS, ARKANSAS AND LOUISIANA RAILWAY," Handbook of Texas Online ([]), accessed August 16, 2011. Published by the Texas State Historical Association.

This short shortline connected its home base in Atlanta, Texas with Bloomburg 8 miles away. It primarily served agricultural and timber producers but would carry passengers. One 1901 timetable showed that the Atlanta-Bloomburg train left Atlanta at 8:10 AM, returning from Bloomburg at 10 AM.

Small Moguls usually had no trouble finding work and when the TA & L folded in 1919, the 3 was sold to Dowling & Camp Lumber Company as their #12. D & CL sold the 12 to locomotive rebuilder/reseller Birmingham Rail & Locomotive.

The next couple of years saw a flurry of transactions. The locomotive rebuilder/reseller sold the engine to Webster County Lumber on 28 February 1923, but the Cumberland, Miss logger sold it back to BR & L within the year. BR & L sold it on to Ingram Day Lumber Company in November 1923 and Batson Hatton Lumber bought it from Ingram Day. Finally BHL sold it to BR & L, who sold it to Georgia Car & Locomotive, who arranged for the 12 to be overhauled at the Gulf & Ship Island shops and sold it to JW McWilliams in October 1924.
