[edit] Steam locomotives

Milwaukee Road steam locomotives were organized into classes by wheel arrangement.

Additional suffixes, where used indicated:

• s: fitted with superheater (where the class was not fitted from new)
• r: fitted with a mechanical stoker (where the class was not fitted from new)

[edit] Class A: 4-4-2

Class A was the 4-4-2 type.
