Regarding it being unusual to see FP-7's in freight service, it was not uncommon to see them on the San Joaquin Division in 1968-69. We had those and passenger F-7's on some of the hotter trains (Fruit Block, No. 375, etc.) usually with six or seven F's and/or a GP9 or two. Regrettably, the only from-the-cab photos I took before leaving railroad service was on No. 375 from Fresno to Roseville, with five F's and a Geep trailing our FP-7 No. 6455. Once we cut off in Roseville, I took a pic of the power waiting to take our train north: Two SD-45's, 8844 and 8875. Considerably less horsepower than what came in with.
