East Texas & Gulf 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 53 (Locobase 15492)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 80, p. 428. See also Megan Biesele, "East Texas & Gulf Railway," Handbook of Texas Online ([]), accessed October 17, 2013. Published by the Texas State Historical Association; Railpictures.net has a 9 February 2010 entry by Tom Sink that shows his photo and comments about the gasoline-engine conversion described below; see http://www.railpictures.net/viewphoto.php?id=313615&nseq=0#remarks, last accessed 17 October 2013. Works number was 60786 in April 1929.

Lodwick Lumber Company's ET&G never was very long, so its motive power requirements could be satisfied by small oil-burning Moguls such as the 53. Its service began after the Hicksbaugh mill closed in 1928, so it soon moved on to other lines, keeping its road number through it all. Welori Lumber Company in Couchwood, La was the second timber company to own the 53. Its next owner was Gifford Hill, and finally the Woodward Walker Lumber of Ada, La bought the aging engine.

Here's where things get a bit bizarre. Tom Sink's photograph shows that for whatever reason, the shop at Ada decided to modify the 53 by installing a Ford V8 engine in the smoke box. After removing the rods (main and side), workers mounted a rear axle from a car or truck over the second driving axle. The driver's disk was fitted with a toothed wheel which was turned by the chain that looped around it and the hub of the driveshaft above it. A chain wrapped around a toothed hub on the second driver and a similar hub on the third driver turned the latter. (One possible wheel arrangment description is 2-4-0, another might be 2(+2)-4-0.

Ky.CatFan commented: "Also I nominate this critter for the Rube Goldberg Award ! Tom did not state if this was an automatic or a stick shift but this is a true oddball.". Mark Heidorn asked: "How about an internal combustion designation rather than one from steam? Say a 1-1-B. Or perhaps there is another chain on the other side making it a 1-C?."

Omahadivision added: "We now have an internal combustion steam engine!"

Locobase knows of another such conversion by the Paauhau Sugar Plantation Company, which he documents at Locobase 14752. That locomotive was a much smaller 0-6-0 saddle tank.
