Yes, you are correct. WP bought A-B-B F3's for passenger service only.
However, the Sacramento Northern, WP's former interurban subsidiary, bought three F3A's from the New York, Ontario & Western when the NYO&W went bankrupt in 1957. One of those was transferred to WP and renumbered 801-D, a passenger unit. The other pair of F3A's worked in freight service on Sacramento Northern, wearing WP colors and SN lettering. SN, like other dieselized interurbans, was not a fast freight railroad.
