Technical notes Milw Road purchased 42 two-unit sets from GE. Classified as EF-1s, the electric motors were initially semi-permanently coupled, and operated in two, three and four-unit sets. "A" and "B" motors were deemed the control locos, while "C" and "D" employed as boosters.

Twelve boxcabs were reduced in length by 14 feet; these "Bob-tail" units included: E25C, E25D, E30C, E30D, E33C, E34C, E34D, E35C and E52C, plus three others.
