I just purchased an MTH PRR Premier N-8 caboose. The item No. on the box is 20-91098. The caboose has a road number 478171 and is designated as Pittsburgh Region. It also has a black cupola (with yellow) and radio antenna.
However I also have another caboose that I purchased years ago with similar paint but with road number 478108. This caboose is shown on the MTH website.
I cannot find a listing on the MTH website that shows this car with road number 478171.
