Regarding the FP45; Milwaukee Road had these without dynamic brakes. Delivered in the UP Colored Passsenger Scheme, later repainted in Orange and Black "freight scheme". Three different lettering options. Small side lettering, Herald only and Large side lettering. It appears that a roof top winterization hatch was added during the first repainting.
I've read the talk about the SDP40F. It would be neat if we could have those as well for Amtrak. If not, the FP45s painted Amtrak might suffice. I hate to ever mention that, but I don't know what the overall interest is for the SDP40F. The HO crowd finally got theirs just prior to covid.
If variations are possible, perhaps the F40C could also be produced. Milwaukee Road had these for the Chicago commuter service. Later repainted into Metra Colors. These ran up until a couple years ago. Metra still has a pair stored.
As far as I, I, I; Me, Me, Me; Me, I; Me, I, Me, I: My interest would be 2 Milwaukee Road Yellow FP45s, 1 Milwaukee Road Orange/Black Herald Only, 2 Amtrak SDP40F's and 1 Metra F40C.
From here, we get into the Calculus of FP45s. In one direction you have the F45 which was ordered by more road than just Santa Fe and Milwaukee Road. In the other direction we have the SD45 which should be a future consideration. And yes, when we get down and dirty into the SD45 discussion, C&NW had them without dynamic brakes and EL had SDP45's, which were a bit longer. Wisconsin Central ended up with one of these (6634), so it would be a request:-)
