Bachmann Spectrum On30 14-Ton Two-Truck Stearns-Heisler


The Stearns-Heisler continues Bachmann's collection of On30 geared steam locomotives along with their On30 Shay and On30 Climax. This 14-ton two-truck engine was an early Heisler, manufactured from the late 1890s.

The Heisler locomotive was the last variant of the three major types of geared steam locomotive. Its designer and manufacturers claimed it was the fastest of the three but retained the low-speed hauling capability. As such it was used in mining and logging/lumbering industries as well as other places which required heavy hauling. From a 1923 Heisler marketing catalog:

"Why you can haul at least 30% more per ton of locomotive with the modern Heisler"

Bachmann has delivered a DCC-equipped model with the fine detailing expected in the Spectrum® line, along with 16-bit Tsunami® plug-and-play sound capability. (Separate-sale Bachmann Item No. 44953, Stearns-Heisler Sound Module, required for sound on board performance)

  • DCC-equipped for speed, direction and lighting control
  • Sound ready with factory-installed speaker
  • Dual-mode NMRA-compliant decoder

Heisler Locomotive Works. Heisler Geared Locomotives Catalog. Erie, Penna.: Heisler Locomotive Works, 1923, 38 pages.
About this book from BarnesandNoble.com: In 1892 Charles Heisler received a patent for a new kind of geared locomotive. Equipped with twin canted cylinders, the engine utilized a drive shaft to power outboard axles and connecting rods to power the inboard axles. As a result of this 'vee-twin' arrangement, the Heisler was one of the fastest geared steam locomotives, providing more power with lower operating costs. Over 600 Heislers were produced from the 1890's until 1941, when the Heisler Locomotive Works closed its doors. This reproduction of the company's illustrated catalog dates from the 1920's. It shows the full line of Heisler products and presents a compelling argument for their use.

About this book from BookFinder.com: Fascinating and handsomely done authoritative history of the Heisler geared locomotive. Chapters include a biography of Charles L. Heisler, a description of the Stearns Manufacturing Co., the Heisler Locomotive Works, the Whitney Engineering Co., the origins, development and refinement of the Heisler, the purpose, distribution and performance of the Heisler, competitors of the Heisler, the construction of a Heisler, Heisler's last years, detailed scale drawings, builder lists, and an owner list. Illustrated throughout with black and white photos. With bibliography and index. Some copies of the book contain an Addenda and Errata Sheet with list of existing Heislers as of November, 1982.
