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. For example, the United States generally used the Whyte notation for steam locomotive classification, but the Baldwin Locomotive Works had their own classification system.
