Many F7s remained in service for decades, as railroads found them economical to operate and maintain. However the locomotive was not very popular with the yard crews who operated them in switching service because they were difficult to mount and dismount, and it was also nearly impossible for the engineer to see hand signals from his ground crew without leaning way outside the window. As most of these engines were bought and operated before two-way radio became standard on most American railroads, this was a major point of contention. In later years, with the advent of the “GP” type “road switchers”, Fs were primarily used in “through freight” and “unit train” service where there was very little or no switching to be done on line of road.
