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 Bangor and Aroostook steam locomotives were likewise similarly classed, however, because the railroad owned a rather small fleet of steamers they are much easier to identify and keep track of. The information here is merely meant to list the general types of steam locomotives operated by the BAR and does not go into detail about their specific differences.
The Bangor & Aroostook never owned large steamers, most of which were only 4-6-0 Ten-Wheelers, 2-6-0 Moguls, or 2-8-0 Consolidations. The railroad's largest steam locomotives was a fleet of 10 Class M 4-8-2 Mountains purchased either new from Alco (the American Locomotive Company) or bought second-hand from the New York, Ontario & Western Railroad. Unfortunately today, no known Bangor and Aroostook steam locomotives survive.

Detailed information about Bangor and Aroostook steam locomotives (such as particular classes, boiler sizes, dimensions, etc.) can be very difficult to come by. However, if you're interested in learning more about the railroad's steam fleet one book which covers such, to some extent, includes Bangor and Aroostook Railroad in Color. The book features is a 128-page colored pictorial of the BAR and goes into some detail about the railroad's steam fleet. While certainly not a complete guide to the railroad's steam locomotives it is quite helpful in learning more about them.
