The classifications given by railroads to their steam locomotive fleets were as varied as the machines themselves with several different designations within a particular class! The Central Vermont Railway steam locomotives also carried several class designations and although the railroad was rather small in size fielded some very large models including 4-8-2 Mountains and 2-10-4 Texas Types. In any event, the information here is merely meant to list the general types of steam locomotives operated by the Central Vermont Railway and does not go into detail about their specific differences.
While the CV did have large steamers like Mountains and Texas Types for heavy drag service in northern New England it tended to rely on smaller wheel arrangements for most tasks such as Ten-Wheelers and Consolidations (along with a few Pacifics). As with the rest of the industry, the CV had retired its steam fleet by the late 1950s in favor of diesel. While none of the railroad's large steam locomotives are known to survive, at least one original CV steamer is known to exist, a 4-6-0 Ten-Wheeler preserved at the Shelburne Museum in Shelburne, Vermont.
