Alfred, did yours come with two stock cars? mine has a reefer car with it
As far as I recall, Lionel/MPC never duplicated cars in the FARR sets. In later years of that time period, there were a couple of unit-trains offered. But the FARR "sets" all had unique cars. I use the term "sets" somewhat loosely though, because I'm pretty certain the FARR locomotives and rolling stock were all available for separate purchase. So it's possible folks could have purchased duplicates of certain cars to suit their fancy. No set boxes as I recall.
