Atlantic Coast Line Mikados

The Atlantic Coast Line received its first "Mikados" from the Baldwin Locomotive Works in 1911. These 20 locomotives were designated as Class M and assigned road numbers 800-819. In 1919 ten Baldwin-built 2-8-2 were added to the roster. The ACL bought seven more Class M-2s from Baldwin in 1923.

The ACL took control of the Atlanta, Birmingham & Coast Railroad in 1926 and merged it into its company in 1945. With the AB&C came seventeen more 2-8-2s.

There are no surviving ACL 2-8-2 "Mikado" type locomotives.
