In terms of making a model, details of one specific one would be needed, as they were generally converted from withdrawn passenger stock. There was at least one, I believe, which had been a horse box! (Probably only had maybe two bunk beds?).
The one above is a former GSWR first class six-wheeler. The thing behind it - I think there were at least two of these. There were also at least two long-wheelbase vans, painted brown even in the grey'n'green era, which i think were originally cattle driver's vans. One was used on the lifting train that was to be seen in West Cork and also Valentia after they closed. Probably Kenmare too.
I remember seeing one in the 1970s somewhere on the Midland, shoved up a siding somewhere, painted green with red ends, as many of those sort of things were. (Livery note; the red quickly faded to either an orangey colour, or a salmony pink). This vehicle was a six-wheeler of indeterminate origin - later research suggested MGWR, but it had the body shape of a GSWR vehicle, and was thus probably a GSR-era rebuild. It had only a few windows. I don't know what became of it.
