”This caboose, which I find strangely enough not listed in any of my collector's guides, dates from about 2011. It was part of a set, called if I recall, the NYC flyer. Its really a nice car with lots of detail and add on features. Its illuminated of course. So here is the Lionel #36670 NYC work caboose.”
From the 6-30200 NYC Flyer Freight Set. There are several other Lionel freight sets with similar names.
