CB&Q F7 164A
Title:  CB&Q F7 164A
Description:  Chicago Burlington & Quincy Railroad F7 164A at Clyde, Illinois on June 6, 1965, Kodachrome by Chuck Zeiler. When it was built in May 1950 (c/n 9693) on EMD Order 3021A, this locomotive was numbered 164 and mated with two F3's (137C and 137D) delivered in October 1948 to produce a semi-permanently-coupled 4500 horsepower locomotive 164. It remained in this configuration until a few months after this photo, when the drawbars were removed and replaced with couplers. At that time, the glass-beaded numberboard between the headlights was removed and the number with the letter A suffix was painted in its place. It was traded in as credit on an order of SD45's in February 1969.

CB&Q F7 164A
Title:  CB&Q F7 164A
Description:  Chicago Burlington & Quincy Railroad F7 164A eastbound at Naperville, Illinois on July 28, 1965, Kodachrome by Chuck Zeiler. I was fortunate to be able to read the model plate on the side of the locomotive, identifying it as an F7. Otherwise, I could not tell the difference between a Phase IV F3 and a Phase I F7, since EMD utilized the same carbody for both models. The following is from the Burlington Route Historical Society's Bulletin #10:

In May 1950, the CB&Q proper acquired its only F7's - 10 A's and three B's. These units had a 36 inch diameter dynamic brake fan ahead of the four radiator fans, thus differentiating them from the Phase IV F3's. Nine of the F7's were numbered as three-unit drawbar-coupled A/B/A sets 167-169, while the other four A's were 163A through 166A. With the delivery of the F7's, two of the previously delivered four-unit F3 sets (137A-D and 138A-D) were broken up and reassembled with the remaining single F7 A-units to make up three-unit F3-A/F3-B/F7-A sets 163 through 166. The renumbering went as follows: 137A became 163C, 137B became 163B, 137C became 164B, 137D became 164C, 138A became 165C, 138B became 165B, 138C became 166B, 138D became 166C. The units in these F3-7 sets matched well, the only outwardly visible difference between the A-units being in the rooftop dynamic brakes. From the ground, the 163-166 sets appeared identical the pure F7 sets 167-169. Later, most of them were split into separate units, coupler equipped at both ends. The three-unit A/B/A sets were not split up until well into the 1960's, with the 167 trio finally being broken up into individual units late in 1965. Suffix letters had been assigned to the locomotives for maintenance purposes, but only appeared in small 1 inch lettering on the side below the word BURLINGTON, until the locomotives were broken up and equipped with couplers at both ends.

CB&Q F7 164A
Title:  CB&Q F7 164A
Description:  Chicago Burlington & Quincy Railroad F7 164A at Clyde, Illinois on October 31, 1965, Kodachrome by Chuck Zeiler. Thic locomotive was built in May 1950 (c/n 9693) and traded to EMD in February 1969. It was delivered as 164 and mated with two F3's previously delivered as 137C and 137D. The F3's were renumbered as 164, and were semi-permanently coupled to the newly delivered F7 to form a single locomotive numbered 164. Suffix letters were assigned to the individual units for maintenance purposes, but not displayed in the numberboards. As delivered, the cab units had glass-beaded numberboards below the top headlight. Sometime between July 28 and October 31, 1965, this locomotive was shopped and the drawbars were replaced with couplers, the glass-beaded numberboards were removed, and the road number with the suffix was painted below the top headlight. The suffix letters were added to the numberboards, and a suffix letter was added to the side number below the side cab window. It is seen here still coupled to the original F3's to which it was assigned, former 137C and 137D, now 164B and 164C.
