Jerry;
If you plan on putting those units into passenger service, the passengers will freeze. There are no steam generators in them as indicated by the lack of the roof detail for them…that’s if proto detail is of any interest to you.
The same can be said for the Aristo FA and FB unit Alcos.
I don’t have any USTrains units to look at, but they may have that detail. I think the USTrains high hood GP7 had indications that it had a steam unit, by a vent on the short hood…but again, I’m just going by memory.
This could offer a neat project for you, which I started a few years ago, but never completed; a steam generator car.
I was getting the parts together to use an old Lionel LS reefer, or was it a plug door box car. It was too short to be of much use for anything else, so I was planning on putting it on a pair of passenger trucks (High speed), and plugging the big doors etc, along with the appropriate other details. With it you could use any unit you cared to, on a passenger consist, and have it appear closer to prototype.
