At first they were PAX only. Later I am sure they were used at time
for frieght service.
If you were modeling the 50s it would be PAX. If later, there are
probably photos of E-7s doing almost anything.
Engines are engines when you're a train master and you've got to get some
trains moving. Freight engines are sometimes put on passenger trains and
passenger engines are put on freight trains.
If you're a decade-based modeller, you'll want to try to keep things as
close to reality as possible.

If they were ever used for freight, it would have been in a very rare motive
power crisis. Consider:
o The UP had continued to have a robust passenger business into the late
1950's: the UP bought new dome cars as late as 1958, the City of Denver /
City of Portland were not combined until 1959 and the Cities of LA / SF in
o The UP needed good passenger power and returned the remaining E-7's to EMD
in the early 1960's for upgrading to E-9's.
o The 13 UP E-7's were geared for 90 MPH and did not have dynamic brakes,
making them less suitable for freight service.
o When the UP reassigned its Alco PA's to freight service, it re-reared them
for lower speed service.
In the late 1960's / 1970 the UP did use E-8's in mixed train service. They
were required to keep running some passenger trains that were down to a
single baggage car and single coach. The UP began treating these trains as
mixed trains, and photos show 2 or 3 E units pulling the two passenger cars
followed by 20 or so freight cars. Geezer
