E22A was converted to EF-1 in 1939 to E22A+B. Twenty-four such combinations were assembled.
E22A+B, as well as her sister E23A+B, were converted to passenger service as class EP-1A in 1954. She was fitted out with a rounded "streamlined" cab front, and repainted with the Union Pacific Railroad paint scheme of Armour Yellow with Harbor Mist Gray roofs, and red dividing lines.

I had a chance to ride an EF-1 monster from Black River Junction to VanAsselt Yard, and was struck by the definite lack of space in the cab, the noise of blowers, groaning of gear sets, and the smell of electricity – ozone.
It is interesting to note that the original freight motors had a top speed of 35 mph. Going faster resulted in the armatures flying apart! Installing high strength steel bands to hold the armatures together and other motor improvements allowed the top speed of 45 mph in the 50’s!

Drawing 3,000 volts DC from the overhead trolley, one hour overload ratings for the GE Motor was 123% of horsepower (3,000 x 2 units) and 132% tractive effort, compared to an F-7 85% and 102%. So they were well suited for the Cascades and Pipestone!
