Yes I remember those circus cars. They are still available from Scenery Unlimited.
They come set up for being pulled by a circus crawler with an add-on wheeled hitch bogie.
The front 5th wheel bogies are removable to allow for road travel.
Early circus wagons were just that...wooden wheeled wagons pulled by trucks, tractors or worst of all animals.
When a more modern circus train was loaded whether or not the wheeled bogies were left under the trailer for transport could be researched. But that has to do with Circus trains specifically.
Early trailer transport on flatcars used temporary hitch stands and lots of chains:
After the invention of the ACF collapsible stand the railroads eventually accepted that all those extra chains weren't needed. The collapsible stands were raised and lowered by air powered socket wrenches.
My addition of the second fixed stand allows an S scaler to model early TOFC traffic.
I'm going to see if I can figure out a way to have the rear stand be magnetically attached to the flatcar. That way removal of the stand for use of a long trailer on the car would be easy.
