I tried that long ago, and it didn't work as far as I can remember. Mind you, the game was still offially known as Railworks back when I did those tests...
In any case, I think the issue was that the car physics simply stopped being simulated when the car got some distance away from the train (or camera, don't remember).
There is only one train simulator that I know of which simulates rail vehicles phyiscs on the whole map:
Derail Valley! Which is in my opinion also the best train game for fans of yard and industrial switching (or perhaps even the best train sim/game ever). It doesn't have a hump yard in it, but some yards are next to a downhill slope which could be used. Kicking (unbraked) cars also works really well in DV.
