QUOTE: Originally posted by CSSHEGEWISCH ATSF had F's, E's and PA's in passenger service. The E's may not have lasted long in mainline passenger service because of grades. They were often found on the Denver-La Junta connecting runs and possibly other light service. The PA's had GE 752 motors so the idler axle may have been less of a factor. After all, many PA's spent fairly long careers pulling freight. F's with steam lines and steam generators were dual-service power and may have filled in on freights during traffic surges. Availability or non-availability of dynamic brake on E's could also be a factor.
