Being the serious and responsible model railroader that I am, now, for some reason, prototypically-incorrect, fantasy-themed equipment seems... well... odd and out of place; but, if I was still in O gauge, I sure wouldn't mind having an Andrew Dice Clay - Nursery Rhyme Box Car set; complete with Dice's lyrics - adorning the sides of the cars... maybe, even, some type of simulated leather-clad locomotive... on point.
What's your pleasure... when it come to fantasy themes?
