Scale Rail,
Nope. Scale-Craft came out with OO well before Lionel who copied their cars and was sued for patent infringement by Scale-Craft. Scale-Craft had patented their truck design and claimed copyright infringement for the cars which were nearly direct copies by Lionel. Lionel settled. Rumor was that Lionel wasn't interested in reviving OO after WW2 as they didn't want to pay any royalties to Scale-Craft - I don't know if that part is really true.
