If the USAT illustration currently on their site accurately represents there NEW F7 offering, I’d suggest it’s depicting an EARLY “Phase 1”, iteration. That said the new intake grilles are a quagmire herein as I can’t definitively ascertain if they are the early horizontal or later vertical configured openings. Providing the grilles are horizontal the new model represents an early Phase 1 F7. If the grilles have vertical openings, LATE Phase 1 is being modeled, if this is the case the USAT F7 late Phase 1 offering is sans several notable updates, i.e., rounded corner cab doors/frames, two weather drip strips over the windows and doors vs one, wing window changes and the delete of kick plates under the steps. In either case the trucks are ill equipped and or modeled with inaccurate braking features.
Perhaps the Daylight schemed F3 and the new F7’s are aimed at pulling passenger car consists, as I noted the F3 is identified/numbered as an E9 in the #6000 series which was painted in Daylight colors and used to pull passenger trains.
I’d suggest the NEW USAT F7 utilizes the original F3 shell, adding a 36” Dynamic Brake fan and replacing the wire intake covers with either horizontal or vertical intake grilles/frames.
