I do not have one of these boxcars but I do have several of the operating signalman cabooses. The cabooses come with the sliding shoes on each truck to be used with the five rail control track BUT it operates beautifully any where on the tracks using just the bell button.
It is a really fun car to operate while the train is in motion wherever you want.
I actually had to glue the pick up shoes in the up position to keep the caboose from derailing on some of my Atlas and Ross switches.
So, I suspect the boxcar you are looking at would most likely operate the same way.
Happy railroading,
Don
