@Csxcellent posted:Something else came to mind. A B&O f3/ft passenger set. The last Santa Fe set had really nice interiors instead of the silhouettes.
The F3 and the FT diesel locomotives are not interchangeable.
The FT were sold in A-B units only
The F3 were available as individual A units and B units.
Somebody has to choose one or the other and not mix-up the concepts.
