@falconservice posted: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.

Some railroads (like Santa Fe) ordered couplers between the FTA and B units. Great Northern ordered ABA sets of FTs.
Lionel's been selling LionChief passenger sets with only an FTA unit for years.
