Class Details by Steve Llanso of Sweat House Media

Class 104 (Locobase 13313)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 32, p. 16. See also S. G. Reed, "BEAUMONT AND GREAT NORTHERN RAILROAD," Handbook of Texas Online (http://www.tshaonline.org/handbook/online/articles/eqb04), accessed October 28, 2011. Published by the Texas State Historical Association. Works number was 33105 in January 1909.

The B & GN was established in 1905 to connect Trinity (about 70 miles mostly north of Houston) with Livingston, which lay 37 miles to its southeast. In 1908, the newly completed line was sold to a Mr R C Duff for his ambitious Waco to Port Arthur line. But in 1910, one of the original investors - William Carlisle of Atchison, Kans -- bought it back and added 15 miles from Trinity northwest to Weldon in the next year.

Duff bought back the now-longer segment of his dream railroad to sell it to the Missouri-Kansas-Texas apparently because they intended to extend the line past Weldon all the way to Waco. Prohibited by the Texas Attorney General from consolidating the line into the Katy proper, the bigger road leased it for 99 years in exchange for a plan to build the Weldon-Waco segment.

Instead, the Katy went into receivership and the railroad grew no larger. When the road reverted to Duff and his investment partners in 1923, they dubbed it the Waco, Beaumont, Trinity and Sabine Railway. The Katy willingly sold Duff the 66-mile Trinity-Colmesneil portion of their Sabine line. Alas for Duff, he was never able to build the Weldon-Waco segment and the whole railroad went into receivership in 1930, a suspension that would last until its official demise in 1961.

During this period, according to Don Ross of http://donsdepot.donrossgroup.net/dr024.htm (last accessed 28 October 2011), its nickname was "Wobblety Bobblety Turnover and Stop." He adds, in a smile-inducing aside, "Now, can anyone pronounce Wobblety Bobblety without grinning?"
