List of Milwaukee Road locomotives

These are locomotives of the Chicago, Milwaukee, St. Paul and Pacific Railroad, often referred to as the "Milwaukee Road". The Milwaukee was acquired by the Soo Line in 1985 and the Soo subsequently became part of the Canadian Pacific Railway.

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.

Steam
Only six Milwaukee Road steam locomotives survive:

In addition, the tender from a class S2 locomotive also survives in Ingomar, Montana.
