A closeup of the cylinders on a Shay locomotive in Washington, United States.

The Shay locomotive, built by Lima Locomotive Works of Lima, Ohio, was the most widely used geared steam locomotive. They were built to the patents of Ephraim Shay, who can be fairly credited with the popularization of the geared steam locomotive concept. Although the design of Ephraim Shay's early locomotives differed from later ones, there is a clear line of development that joins all Shays.
