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.

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. 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.
