World War II slowed production of Diesel locomotives. GM was allowed to keep producing them provided it didn’t interfere with its production of Diesel engines for the Navy. However, it wasn’t allowed to design new locomotives, so the FT remained in production until the end of 1945. As with the E6, close examination suggests that GM artists used at least four foundation drawings for the FT, two facing right and two left.

There is no signature on this painting but my guess it that it is by Harry Bockewitz.

Like its partner Western Pacific, Rio Grande purchased twelve four-unit FT locomotives. It received the first one, the one shown in this painting, in January 1942.

Another painting that is probably by Bockewitz.

Seaboard’s first of 11 four-unit FTs was delivered in June 1942. Both it and the next five four-unit locos were painting in Knickerbocker’s citrusy color scheme. Later FTs would be painted black with a broad white stripe that was easier to maintain and eventually the early FTs would be repainted to match.

This painting is signed B. Dedek and dated February 3, 1944. We’ve already seen paintings by him dated February 4 and 8; he must have been doing one a day.

B&O ordered six four-unit FTs and confusingly numbered the first four 101, 5, 7, and 11. The first was delivered in August 1942, but number 11 was probably not delivered until October 1943.

This painting is signed B. Dedek and dated September 17 1943.

Atlantic Coast Line ordered 12 four-unit FT locomotives and the first, number 300, arrived in September 1943. This means that GM’s delivery of locomotives have caught up with Dedek’s paintings of those locomotives.

This painting is signed B. Dedek and dated what looks like August 10 1943, which would be just before it was delivered.

Boston & Maine is another railroad that bought twelve four-unit FT locomotives, starting with 4200 which was delivered in September 1943.

This painting is unsigned but looks like Bockewitz’s work.

Here’s another locomotive for which GM issued two different data cards. This is the same locomotive as the previous picture and painted on the same foundational drawing but the surrounding vegetation is a little different.
