The diesels were built by Electro Motive Company before being absorbed by General Motors and becoming a division of that company (EMD). EMC considered (2) two unit sets of 2750 hp back to back a single locomotive (A-B-B-A). Interestingly enough, the name "FT" is derived from "Freight-Twenty-seven hundred HP" total.
The units were delivered in 1941. In 1954, FT 102 sports a modified "Catwhisker" paint scheme, cream yellow and blue, and red pin stripes on the nose section. There were many variations to this paint scheme.
