@BlueComet400 posted:Thanks guys; these are beautiful cars but I prefer trains longer than 4 cars. The hunt begins for the add-on cars!!
John, since the PRR often mixed up their passenger consists, you could widen your search for some of the other K-Line PRR 18” cars. There are some 2 and 4 car sets you could add to your Spirit of St. Louis set, such as the Jeffersonian or Broadway Limited sets. They are often on eBay. You could even add in a Congressional car set too.
Good luck with your search!!
