| 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. |
