Enjoy this wonderful 28 page heavily illustrated catalog, with specifications, company history, and most importantly photos of a wonderful variety of locomotives.
The Heisler locomotive was the last variant of the three major types of geared steam locomotive, Charles L. Heisler receiving a patent for the design in 1892 following the construction of a prototype in 1891. Somewhat similar to a Climax locomotive, Heisler's design featured two cylinders canted inwards at a 45 degree angle to form a 'vee-twin' arrangement. Power then went to a longitudinal driveshaft that drove the outboard axle on each powered truck. The inboard axle on each truck was then driven from the outboard one by external side (connecting) rods. The Heisler was the fastest of the geared steam locomotive designs.
