| Chicago Burlington & Quincy Railroad F3 164C at Clyde, Illinois on October 31, 1965, Kodachrome by Chuck Zeiler. Delivered October 1948 as the rear cab of semi-permanently coupled F3 A/B/B/A set 137, for maintenence purposes it was numbered 137D, but only 137 was displayed in the numberboard. In May 1950 the CB&Q acquired 10 F7 A's, and broke the 137 (and 138) sets into A/B F3's and mated them with the new F7 cabs, producing four three-unit motors (CB&Q term for coupled locomotives) 163 - 166. Again, the suffix letter was not displayed in the numberboard until the 1960's when the motors were broken up into individual units, couplers were installed at both ends, and the suffix letter was painted on the nose and applied to the numberboard. |
