The photo on the right shows a 570 Series loco as first delivered in the Fall of 1942 (my birth year) and they were quickly dubbed "Yellow Jackets" for obvious reasons. The 576 as it appeared on home rails after 65+ years in Nashville's Centennial Park on March 9th is in photo on the left. As,delivered, they had cast conical smoke box fronts and wide skirting painted yellow. For ease of maintenance, the conical fronts were later replaced and the wide skirting removed, so that the running boards were painted with a single stripe of yellow paint.
