Steam & Excursion > V4!

Hey gang, did anybody ever make a V4 Heisler?

Uh, almost.

"The first Heisler engine was also the last built at Dunkirk, for Charles Heisler left Brooks shortly after the engine was completed. He moved to Philadelphia and searched for a company to manufacture his locomotive, which he patented in 1892 after making some design improvements.

An agreement was soon reached with Stearns Manufacturing Company of Erie, Pennsylvania, and the first Stearns-built Heisler was shipped in 1894. Large-scale production of engines ranging from fourteen to sixty-five tons soon followed. In 1897, Charles Heisler patented a three-truck locomotive that included an optional four-cylinder engine. Although a number of three-truck Heislers were built, there are no indications that the four-cylinder design was ever constructed."

Thanks Jack...I'm going to guess that in a 4 cylinder design, there was no real way to significantly improve on the power or even the torc on the center drive shaft given the relatively light weight and adhesion of even a 3 truck Heisler....
