Ok, I try again, in my faulty English.
Rolling stock is, well, rolling stock.
Cars used to transport livestock are called stock cars or cattle cars, or both?
Obviously, asking about green stock cars in ATSF rolling stock might have sounded confusing, so I opted to ask about cattle cars.
I do have a book about Santa Fe Freight and passenger equipment, and none of the stock cars /cattle cars /whatever is green.
Without said book, I would not have even suspected of the uncorrect greencolor.
Now, in N scale, at least two manufacturers, whose products I purchased, and other manufacturers that I am aware of, but whose products I did not bother to buy, made the same mistake, and followed Lionel's goofing.
It is obviously my layout, and I know I could run whatever color pleases me, but I happen to prefer to have my equipment in prototypical livery.
So, I have to repaint any cattle car ( be it green or whatever color it comes in) in the correct ATSF color.
One solution would be to mark as ATSF the pre merger Burlington cars, but were they actually green? A yes or no kind of answer would be the helpful one.
