I suspect not. The passenger car might have been coupled to another or additional locomotive

I hope someone can answer this question definitively. I know in some cases it did happen, involving "change of gauge", hence the term. I do not know but I suspect that was fairly rare except when crossing national borders with different gauges. Now I am curious, so I will try to research it unless someone does know the correct answer.
