| Chicago Burlington & Quincy Railroad E7 9949 at Denver, Colorado on August 20, 1964, Ektachrome by Chuck Zeiler Built in September 1947 (c/n 4501) on EMD Order E792A, it became BN 9925 and was retired in September 1970. This unit is the only E7 on the CB&Q roster that did not have a suffix letter. There was only one other single E7 (9937A), all the other E7's were ordered in pairs. Also, the first E8 was numbered 9937B, and there was a single E8 numbered 9949A. I cannot explain why this unit was not numbered 9937B. |
