All the locomotives listed here actually operated at one time or another on a North American railroad. This includes common carriers, elevated railways,cog railways and logging roads.
Whyte's system of classification is used to describe the wheel arrangementof conventional steam locomotives. In this system, the first number is thenumber of leading wheels, and the last is the number of trailing wheels. The middle number (or numbers) give the number and arrangement of drivers.
A "T"at the end indicates a tank engine. The system normally used to describe diesel-electric locomotives has also been used here for steam turbine electric locomotives. In this system,non-powered axles are given as numbers and powered axles are given as letters.There is no standard system of classification for geared locomotives such as Shays, Heislers and Climaxes. Instead, a brief description is given for each.
