Well aren't we just getting spoiled by passenger equipment announcements of late ? A full size RPO isn't really all that useful to me but were the .I'll Rd and GN versions accurate I'd be hard pressed not to dive in - anyone know how close these are to a Mil Rd or GN version (I'm not near my Morning Sun books so I can't check anything)
This looks like the same prototype that's been done twice in N scale so far. Once by ConCor (poorly) and once by Kato (better). Fortunately the CCS version will likely have separate grabs and actual steps which the Kato version is sorely lacking. And it will come in more appropriate paint schemes. Off hand here's what I remember about these car.
UP is correct. C&NW had some as part of the Cities pool, they started in yellow and gray UP colors and did end up in C&NW yellow and green later. I'm not sure if it was the early scheme with the black pinstripes at that point, maybe someone can chime in. That also means that the SP cars might be correct under the same Cities pool thinking.
Milwaukee Road did reconstruct at least one car to mimic the UP car series. It might have had the wrap around vents on the roof though. And possibly port holes instead of rectangular windows in the doors. But doable with this release.
GN would be correct. The difference between the GN and UP cars was some shallow cutouts above the trucks. The Kato car had these (UP correct) so maybe the CCS car will have a straight sill and be the GN version.
IC is sorta close. The RPO windows were different proportion and the wide baggage door should be moved toward the middle of the car. I did the conversion in HO on the similar Walthers car. If you're good, you won't have to repaint.
I can't think of anything PRR/PC that's close off hand. Anyone know of a match?
NYC's similar cars had four split framed windows.
