| Chicago Burlington & Quincy Railroad F3 136A eastbound at Naperville, Illinos on February 12, 1966, Kodachrome by Chuck Zeiler. The EMD F-units were known as Graybacks on the CB&Q. This particular unit (or motor, as the individual units were called on the Q) was built on EMD Order E-957 in November 1948 (c/n 7018) as the lead cab of a drawbar-coupled A-B-B-A set of Phase IV F3's, road number 136. Beginning in 1951, the Burlington began replacing the drawbars with couplers, at first breaking the A-B-B-A sets into A-B sets, still drawbar coupled. Eventually even those drawbars were replaced with couplers. This motor was traded in to EMD on an order of GP40's in March 1968. |
