The last new diesel to be introduced by Atlas in the mid-1970s was an FP7. Late 1975 saw four road names and an undecorated FP7 join the collection of EMD HO-scale prototypes in the Atlas collection. This FP7 tooling would enjoy the longest run with Atlas and would also serve as the basis for an E-R Imports offering.
