What was the Plymouth Locomotive Works?

This diminutive engine is the only one at IRM built by Plymouth. Plymouth was one of the most prolific builders of small internal combustion locomotives in America. Located in Plymouth, Ohio, the company – whose corporate name at the time was actually the Fate-Root-Heath Company – built its first gas-mechanical locomotive in 1910. It began constructing diesel-powered locomotives in the late 1920s. It built a handful of larger switchers, but almost all of its locomotives were small ones like this one and were built for industrial or mining operations. Plymouth remained in business until it was sold to Ohio Locomotive Crane in 1997.
