Electric

The Milwaukee Road was one of the most electrified railroads in the United States. The system used was 3,000 volt DC overhead line.

Switchers

Milwaukee Road class ES-1 - 1 example (built 1915), the Great Falls, Montana switcher. Used 1,500 volts DC.
Milwaukee Road class ES-2 - 4 examples (built 1916–19).

Passenger

Milwaukee Road class EP-1 - 12 2-unit boxcab sets (24 locomotives) built in 1915 by ALCO/GE. Converted to freight class EF-1 in 1920. In 1950, two boxcab two-unit sets were converted for passenger service (class EP-1A).
Milwaukee Road class EP-2 - The "Bi-Polars". 5 built by GE in 1919.
Milwaukee Road class EP-3 - The "Quills" (quill drive). 10 built by Baldwin/Westinghouse in 1919.
Milwaukee Road class EP-4 - "Little Joes". Two examples built by GE in 1946. Converted to freight class EF-4 in 1956.

Freight

Milwaukee Road class EF-1 - 30 two-unit boxcab sets (60 locomotives) built in 1915 by ALCO/GE, identical to EP-1 but for gearing and paint. In addition, the EP-1 units were converted to EF-1 specification in 1920.
Milwaukee Road class EF-2 - 3-unit boxcab sets formed from EF-1s in the 1930s.
Milwaukee Road class EF-3 - 3-unit boxcab sets formed from EF-1s with the middle unit shortened by removing the cab and leading truck; the resultant B units were known as "bobtails".
Milwaukee Road class EF-4 - "Little Joes". 10 examples built by GE in 1946 for the Soviet Ministry of Railways as Class A. In addition, the EP-4 locomotives were converted to EF-4 specification in 1956.
Milwaukee Road class EF-5 - Four-unit boxcab sets formed with any combination of regular or bobtail units in the middle.
