In 1892 Charles Heisler received a patent for a new kind of geared locomotive. Equipped with twin canted cylinders, the engine utilized a driveshaft 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.
