Thunder Mesa No. 8 ~ The R. H. Gurr

The Bob

Thunder Mesa's newest locomotive is a trusty and reliable 14-ton Stearns-Heisler, circa 1895. The repainted and detailed Bachmann model is named in honor of Disney Imagineering legend, Bob Gurr. It has always been Thunder Mesa's practice to name its locomotives in honor of Disney artists and Imagineers, and If you're not familiar with Bob Gurr, you should be. He designed just about everything with wheels in the early days of Disneyland, including the Monorail, Autopia cars, and Main Street vehicles. On the Thunder Mesa layout, the R. H. Gurr wears the number 8, and has the distinction of being the first geared locomotive used on the line. Lacking a third truck, #8 has something of a short, squished appearance, and that has earned it the nickname of "The Bob" with the Thunder Mesa crews.

Heisler History

Thunder Mesa's R.H. Gurr locomotive is based upon a small, 14-ton version of Charles L. Heisler's 1892 patented design. Heisler's design featured two cylinders canted inward at a 45º angle, with power transferred via a center mounted longitudinal drive shaft connecting enclosed gearboxes between the truck frames. Outside connecting rods then distributed power between the wheels. This was a variant similar to the Climax design where the cylinders are canted at an angle but mounted inline with the locomotive boiler.

The Stearns Manufacturing Company of Erie, Pennsylvania built Heislers from 1894 to 1907, when they reorganized as the Heisler Locomotive works and continued producing the design until 1941. As befitting a locomotive name in honor of Bob Gurr, Stearns claimed that the Heisler was the fastest of the geared locomotive designs, but with the same low-speed hauling ability as a Shay or Climax.

Though a later model, Roaring Camp & Big Trees Narrow Gauge Railroad's Stearns-Heisler #2, the Tuolumne, inspired some of the color and design choices on TMMC's #8. The Tuolumne originally belonged to the fabled West Side Lumber Company where it wore the number 3.

 

The Bachmann Stearns-Heisler

Bachmann's On30 version of the 14-ton Stearns-Heisler is an accurately detailed and fine running model without any of the split gear issues that plagued their Climax and Shay offerings. Mine has become the reliable workhorse of the TMMC and you can see it earning its keep at most Open Studio days. I look forward to adding another to the roster at some point in the future.

For this model, I replaced the original cab with a Banta Modelworks cab kit and stained the wood cherry red. Then I stripped the factory paint and decals off of the tender and repainted it with a gloss Hunter Green, painting the cab window trim to match. I replaced the headlight with a backdated box-style headlight salvaged from an old Bachmann Porter, then built up a new load for the tender from real Utah Juniper twigs, split and stacked as cordwood. The pilots and running boards were all repainted to add realism and dull the shine. Custom water-slide gold decals where printed for me by Stan Cedarleaf, and the crew is a pair of repainted Arttista figures. The tools and details are white metal castings from Wiseman Model Services.

I hope Bob will forgive me for naming a slow, geared locomotive after him. He would probably prefer something sleek, fast, and candy-apple red!

Thanks for checking in, amigos. Adios for now!
