Class (locomotive)
A class of locomotives is a group of locomotives built to a common design, typically for a single railroad or railway. Classes can vary between country, manufacturer, and company.[1] For example, the United States generally used the Whyte notation for steam locomotive classification,[2] but the Baldwin Locomotive Works had their own classification system.[3] A list of locomotive classification systems follows:
