Unfortunately, according to John B McCall's Modeling Santa Fe Passenger Service FT article, it seems that all of the latest O scale SF passenger FT's are missing an interesting detail Santa Fe modelers might want to consider.
I modified the opening sentence to more properly represent my thoughts. I consider the info in McCall's article to be of interest to Santa Fe modelers that own FT passenger units and wanting to add details missing from the models. This had nothing to do with a critique of the recent Sunset and Key FT's. I would leave that to those more knowledgeable than I.
McCall's excellent article in the Warbonnet publication of the SFRH&MS is very well researched and includes excellent pictures. He covers many questions commonly asked, but to me the newest revelation is that the passenger FT's had very visible screened vents in the rear side access side door on A units and both side access doors on B units.
The prototype pictures show them opened and black or with a silver colored metal cover. Either way they are visible. Mr. McCall modeled his HO units using cut black number board decals (2 on each door) to represent the vents.
Has anyone attempted to model this on their new passenger FT's?
