| Chicago Burlington & Quincy Railroad SD24 509 at Clyde, Illinois on March 7, 1965, Ektachrome by Chuck Zeiler. Built in May 1959 (c/n 25206) on EMD Order 5598 for 16 SD24's, it became BN 6249 and was retired in June 1982. A couple of notes about the SD24 in general: the semi-circular bulge in the hood behind the cab is often referred to as the turbocharger bulge; in fact the bulge accommodated the traction motor and generator blowers. The SD24 was the only EMD product equipped with D-47 traction motors which did not work in its favor when it came to stocking replacement parts. And, the SD24 was EMD's fist foray into the turbocharger arena, and like most first efforts, it was not without problems. |
